16GB USB Flash Drive
I needed a new USB flash drive, so I went to Amazon and browsed for a while. I chose this one mostly because it had a good capacity (16GB) and it came in assorted colors. Before, I had a grey USB drive and most recently a black one. It was nice to be able to choose something more colorful. Available colors are cyan (blue), yellow and pink. Another nice feature is that there isn't a loose cap to lose. The flash drive has a metal cover that slides to the side when you need to plug it into your USB port. When you're done, you can just slide the cover back over the USB connector. This cover is easy to move, but that also means that it is easy to bump out of the way unintentionally. I wouldn't recommend putting this USB drive on your keychain. It would likely be okay on a lanyard. There are two small holes on the end of the metal cover, and it looks like it would be hard to run a cord through them. If it were on your keychain, I think it would be jarred open simply by everyday use of your keys. There is a small green light that comes on when you first plug in this USB drive and also when it is in use. It reads and writes at 10 MB/sec using USB 2. The drive is 2.19 inches long, 0.68 inches wide, and 0.36 inches high. I paid $31.98 on Amazon. I'm not sure how reliable their list price information is, but the website currently says this flash drive costs $45.99. I also got free shipping, which is always a good reason to buy from Amazon.The package says it works with Windows Vista, XP and 2000, as well as with Mac OS X 10.3.x+ and Linux 2.6.x+. It even has a five-year warranty, and if you go to the website listed on the package you can file a claim or get technical support. Overall, I am very happy with this drive. USB drives have made it extremely convenient to carry and transfer large files, especially if you are a student.

DataTraveler Locker+ 16GB USB Flash drive
USB Flash drives are a great way of carrying around portable data. However, keeping this data safe from prying eyes usually requires some form of security; whether it is password or encryption protection. In most cases, hardware encrypted USB Flash drives are the most secure way of locking up ones data. Of course these drives can be rather expensive. Thankfully, Kingston has released the relatively affordable DataTraveler Locker+ USB Flash drive, which features hardware-based encryption.
With the DataTraveler Locker+, Kingston implements a 256-bit AES hardware-based encryption to protect its contents. To keep this data safe, the DataTraveler Locker+ will lock down and reformat after 10 intrusion attempts. Now if you lose or have your USB Flash drive stolen, the encrypted data is protected from ever being accessed. The DataTraveler Locker+ is totally encrypted requiring a password to be entered each time the drive is plugged into a computer. Kingston makes a similar model called the DataTraveler Locker which allows the user to create both a secure and unsecure partition. On the DataTraveler Locker+ there is not unsecure partition.
The DataTraveler Locker+ is available in 4, 8, 16 and 32 GB sizes and does not require administrator access or any installation of software to run on Windows machines. It also works on Macs running OS X (10.4 or higher).
The Kingston DataTraveler Locker+ comes on a blister card with the standard Kingston packaging. On the back of this card is a list of features and an OS compatibility table. What separates the DataTraveler Locker+ from other hardware-encrypted drives is the Mac OS X 10.4-10.6 capability. As a dual OS user this is a terrific feature; thank you Kingston for the Mac love.
Inside the packaging we find the drive, a lanyard and the white backing card.
The DataTraveler Locker+ should look very familiar to the owners of the DataTraveler 400 as the USB housing is identical. The device measures 65.76mm x 17.98mm x 10.7mm is a swivel design which eschews the cap solution. Another nice touch by Kingston as I tend to lose USB Flash drive caps rather quickly.
DataTraveler Locker+ is composed of a gunmetal grey aluminum exterior, which swivels off the actual drive that is covered by a black rubber material. The aluminum housing has an opening at one end for attaching the included lanyard.
Markings on the drive include the DataTraveler Locker+ name and drive size on one side and the Kingston logo on the other. Next to this Kingston logo is an opening for the operating LED found on the black portion to shine through.

DataTraveler Locker+ 16GB USB Flash drive
Kingston’s DataTraveler Locker+ USB Flash drive is ideal for people and organizations that require the most secure way to store and transfer portable data. It uses hardware encryption to safeguard 100 percent of stored data in case the drive is lost or stolen. No need to worry about sensitive and personal documents ending up in the wrong hands. DataTraveler Locker+ also provides a fully customizable security policy.
Kingston’s DataTraveler® Locker+ USB Flash drive is designed for organizations that require a secure way to store and transfer portable data. One hundred percent of the stored data is secured by hardware-based encryption to guard even the most sensitive data in case the drive is lost or stolen.
Features/Benefits:-Full Encryption — 100 percent of stored data is protected by hardware-based encryption -Secure — drive locks down and reformats after 10 intrusion attempts. -Enforced password protection — complex password issuer set with minimum characteristics to prevent unauthorized access -Easy to use — no admin rights or application installation required -Guaranteed — five-year warranty and 24/7 tech support
Specifications:-Capacities — 4GB, 8GB, 16GB, 32GB -Dimensions — 2.58″ x 0.71″ x 0.41″ (65.76mm x 17.98mm x 10.7mm) -Simple — just plug into a USB port -Guaranteed — five-year warranty -Minimum System Requirements — –USB 2.0 compliant and 1.1 compatible –Two (2) free consecutive drive letters required for use+
For testing the DataTraveler Locker+ I used my MacBook Pro running Snow Leopard (OS X 10.6) and my Desktop PC with Windows 7 64 Bit Professional installed. Upon insertion of the Kingston USB Flash Drive we see a 9MB file named DTplus appear on the desktop. This is a read only file and is recognized as a CD/DVD file type to prevent erasure. On Windows machines the file should autorun and start the setup process, while on the Mac side the user needs to manually open the folder and start the installation from the Mac subfolder.
Setup takes less than a minute and involves selecting the default language, accepting the License Agreement and finally choosing a password. Kingston requires the password to be 6 to 16 characters long and contain three of the following: upper case letters, lower case letters, digits and special characters. Before the initial format Kingston allows Contact Information to be entered. Once the format is completed we see the 16GB drive on either the Windows or Apple machine.
Initially when I first plugged in the DataTraveler Locker+ into my MacBook Pro, I was unable to execute the DTLocker+ application and received the following error:
After some investigation I found the System Preference program USB OverDrive caused a USB conflict and once I uninstalled this program and rebooted I was able to use the DataTraveler Locker+. So if you are running any third party programs and have issues with installation or reading the USB drive, check to see if anything is tied to the USB control.
Every time the DataTraveler Locker+ is plugged into a Windows or OS X machine, the password needs to be entered to access the contents on the drive. From the Dock in OS X and the System Tray on Windows we find the DTLocker icon from which settings can be changed, the drive can be formatted or unmounted.
To compare the speed of the DataTraveler Locker+, I pitted it against some recent large capacity USB Flash drives including the DataTraveler 400 (16GB) (a password protected but not encrypted drive), Corsair Voyager 16GB and the OCZ Rally2 64 GB drives.
For testing I used DiskBench running the copy and read bench marks. As you can see the DataTraveler Locker+ was actually faster than the others on both benchmarks with the hardware encryption running. This was quite surprising, so I ran another set of benchmarks with the same four drives.
For the second test I used HD Tune Pro 4.0 running the Read benchmark. The two Kingston Drives ran at similar speeds while the Corsair and OCZ drives were slightly slower. None of these drives are designed for speed performance but for everyday use. The DataTraveler Locker+ seems to hold its own and actually stands out against these drives even with the hardware encryption running.
Since the ENTIRE USB drive is encrypted, a password must be entered each time the drive is plugged into a computer. This may be a hassle to some, but for true security there is no way around this.
Of course for security and protection that is found in the Kingston DataTraveler Locker+ there is a premium to be paid and that is the price of the actual device. It is generally more expensive than similar capacity flash drives. But for this price you are getting security, cross platform capability and Kingston’s five year warranty.
The main drawback to the DataTraveler Locker+ is that it will not work with Linux. Hopefully Kingston will remedy this issue in the future for Linux users making this the optimal cross platform USB Thumb drive security solution.
Conclusion:
When grading the Kingston DataTraveler Locker+ against non-encrypted competitors it is a very good USB Flash Thumb drive. But once the security feature is taken into account the DataTraveler Locker+ becomes a phenomenal USB drive. The hardware encryption allows the Kingston drive to work in numerous computing environments including OS X and Windows machines without administrative access.
It is a 100% secure drive and all the contents within are protected by 256-bit AES hardware-based encryption. If you prefer to have a public and private partition then the Kingston DataTraveler Locker would be advised. However for the the truly security obsessive such as myself and business environments then the Kingston DataTraveler Locker+ is an ideal solution

16gb USB Drive Comparison – 17 Drives Compared
Yep, I’m at it again, this time I’ve got an assortment of 16gb USB drives, 17 of them in total from many different companies. I went and did a bit of searching and collected some of the more popular drives out there today, along with many others as well. I think we’ve got a nice representative sampling overall, we’ve got Sandisk, Verbatim, PQI, Kingston, OCZ, Patriot, Ridata, Imation, HP, Adata,Corsair, Memorex, Super Talent, PNY and Transcend in this little roundup.
I’d like to thank Super Talent, OCZ, PNY and Kingston for sending me drives for this little roundup.
So read on for some graphing fun… we got some extreme graphage going on inside…
So here’s the drives in the test:
Adata Sport Series RB19 16gb Corsair Flash Voyager HP USB Flash Drive v125W Imation Swivel Flash Drive Kingston Data Traveler100 Kingston DataTraveler HyperX Memorex Traveldrive OCZ Diesel OCZ Throttle Patriot Exporter XT PNY Attache PQI Traveling Disk 1221 Ridata EZdrive Lightning Series Sandisk Cruzer Micro Super Talent Pico-C Transcend JetFlash Elite Enabled Verbatim Store ‘n’ Go
and just for your information my system basically consists of:
Intel C2Q9650 CPU
8gigs OCZ Ram
EVGA NF680i SLI Motherboard
Windows Vista Ultimate x64
Ok, now onto the testing phase.
First up is SiSoft Sandra 2009 Sp2 Removable Storage Benchmark.
Combined Device Index: is a composite figure representing an overall performance rating based on the average of the Combined Index figures over the four file sizes. (Higher is better, i.e. better performance)
Endurance Factor: is a figure representing the Wear and Life Expectancy of flash devices; this is obtained by dividing the average performance (normal condition, i.e. sequential write) to the lowest performance (high-stress condition, i.e. same block re-write).
It measures the relative improvement of endurance caused by the wear levelling or flash management algorithm; the absolute endurance of a device (i.e. its expected life-time) is directly dependent, in addition to this Endurance Factor, on the nominal manufacturer rating of maximum erase/reprogram cycles, which is typically 100,000+ for SLC and 10,000+ for MLC devices. (Higher is better, i.e. longer life-time for the device)
In the following graph the higher scores are better, I’ve arranged the chart from worst to best according to how SiSoft Sandra scored them:
The top five as we see according to SiSoft Sandra are OCZ, Sandisk, Super talent, Patriot and Imation.
Here’s a closer look at the test, specifically the 256MB Files test, here we can see how Sandra scored the Read Performance and Write Performance of the drives. The chart is arranged using the Write Performance as the reference, worst to best, and of course higher is better.
As we can see we’ve basically got six drives tied for first place in this test.
Now, I’ve got Diskbench test up next, but I’ve done it a bit different this time, since there’s quite a few it gets a bit crowded, so I’ve broken the individual tests down into separate graphs. Also I added another test in here as well, I figured since these were 16gb drives, I would thrown in a nice large file transfer test as well, I used the Windows7 ISO file weighing in at 3.15GB. I also used the same 350MB .AVI Video file that I always use as well.
Diskbench is nice in that it tells us the actual times and transfer rates to complete the tasks of Copy To or Write To the USB drives, Read From and Copy From as well. I run these three tests on my USB drives because they are the most common things people are going to be doing with their USB drives.
First up is testing with the 350MB .AVI Video file, lower scores are better as they are shown in seconds. The first test is for Copy To or Write To the USB drives.
As you can see the OCZ Throttle drive has the fastest write time for this size of file, coming in three seconds faster than the closest competitor. The other fast drives all come it at around 20 seconds to complete the task which is very good overall. We can also see the Adata and Sandisk drives are over one minute, not that good really.
Next test is Read From, this test simulates reading a file from the USB drive, again it’s in seconds so lower is better.
Here we see a bit of rearranging going on with the ordering, with the top drives coming in at around 11 seconds.
Next test is the Copy From test, this gives us the time it takes to copy from the USB drive to my hard drive.
The ordering here is close to the Read From test but not the same, still though the PQI drive is number one.
Now here are the transfer rates for the tests in MB/s, so higher scores are better or meaning faster.
First graph is showing the results for the Copy To or Write test:
Clearly the OCZ Throttle is a fast drive coming in almost a full 3MB/s faster than the nearest competitor. Though 16 and 17 MB/s isn’t bad at all either, it’s nice and fast.
Next graph is Transfer Rates for the Read From test, higher is better of course:
Over 30 MB/s is good, very good actually for a USB drive, and we see quite a few hit 30 and above in this test.
Finally we have the Transfer Rates for Copy From:
Again over 30 MB/s is good, hitting 32 MB/s and above is even better as we can see a few are able to accomplish, most of the drives though aren’t too bad in this area really.
Ok, now for the last set of tests using Diskbench, this is where I used the ISO file that is 3.15GB in size. Same tests here, Copy To, Copy From and Read From, but I decided to only show you the times it takes, and not the transfer rates as they are pretty much the same as the other test, but seeing the actual time to do something can sometimes tell us more than seeing the transfer rates, at least I would rather see the times to do something, it’s easier to understand.
First up again is Copy To or Write to the USB drives, lower scores or times are better.
Over two minutes to copy the file to the USB drive for all of them, with the OCZ Throttle coming is number one here again, with a good 20 seconds better time. The main reason I wanted to show this is that things change with file sizes, the ordering of the drives has changed with the larger file as opposed to the smaller file transfer. Some drives got better when transferring the larger file, while others performed worse. The Patriot drive got worse, while the HP drive got better, the Kingston HyperX got worse, and so did the Verbatim drive. The PNY drive was actually in 12th place on the 350MB file test, here we see it moved up a few spots to number eight on the list.
Next is the Read From test:
Again the OCZ Throttle drive is number one, still the top five drives are all very close in performance for this test. Again the ordering has changed from the 350MB file test.
and finally here’s the results for the Copy From test:
and yet again the OCZ Throttle drive is in the top spot, and one thing has remained the same for all of the tests I think, the worst is still the worst no matter how you look at it… anyone want a Transcend drive?….
Seriously though, if I had a choice of these drives it would be the OCZ Throttle, but then again it might not be. Yes it’s the fastest of the bunch, but it’s a hybrid drive, it’s got both eSATA and USB connections on it, and to use the USB connection you need to carry a small USB cable with you with mini-USB connector to plug into the Throttle, to me that’s a bit of a hassle really. The next choice would be tied between the Kingston HyperX and the Patriot Exporter XT drive, both are fairly fast and both have good qualities in their construction as well. Then again why would I bother with 16gb drives when I’ve got 32gb and 64gb ones on hand?
If I’m looking for a USB drive, the first thing I look at is the Copy To or Write speeds, this is what is most important to me, the next thing would be the Copy From speeds, as for me what I do most is put data on it, then take it off, reading from the drive is not that important to me really. So it all depends on what your priorities are concerning USB drives, the results are here, you can judge for yourself which is best for you.
If I had to give an ordering for the top three drives, taking everything here into account ,including my preferences, it would have to be the OCZ Throttle coming in first with the Kingston HyperX in second, the Patriot Xporter in third. Those are the ones that I would buy personally.
I hope you enjoyed this, I had fun doing it, I’ve got an even larger one in the works as well, but it’s going to be a bit different, so be on the look out for that within the next couple weeks.
I’d like to thank Super Talent, OCZ, PNY and Kingston for sending me drives for this little roundup.

The ordering here is close to the Read From test but not the same, still though the PQI drive is number one.
Now here are the transfer rates for the tests in MB/s, so higher scores are better or meaning faster.
First graph is showing the results for the Copy To or Write test:
Clearly the OCZ Throttle is a fast drive coming in almost a full 3MB/s faster than the nearest competitor. Though 16 and 17 MB/s isn’t bad at all either, it’s nice and fast.
Next graph is Transfer Rates for the Read From test, higher is better of course:
Over 30 MB/s is good, very good actually for a USB drive, and we see quite a few hit 30 and above in this test.
Finally we have the Transfer Rates for Copy From:
Again over 30 MB/s is good, hitting 32 MB/s and above is even better as we can see a few are able to accomplish, most of the drives though aren’t too bad in this area really.
Ok, now for the last set of tests using Diskbench, this is where I used the ISO file that is 3.15GB in size. Same tests here, Copy To, Copy From and Read From, but I decided to only show you the times it takes, and not the transfer rates as they are pretty much the same as the other test, but seeing the actual time to do something can sometimes tell us more than seeing the transfer rates, at least I would rather see the times to do something, it’s easier to understand.
First up again is Copy To or Write to the USB drives, lower scores or times are better.
Over two minutes to copy the file to the USB drive for all of them, with the OCZ Throttle coming is number one here again, with a good 20 seconds better time. The main reason I wanted to show this is that things change with file sizes, the ordering of the drives has changed with the larger file as opposed to the smaller file transfer. Some drives got better when transferring the larger file, while others performed worse. The Patriot drive got worse, while the HP drive got better, the Kingston HyperX got worse, and so did the Verbatim drive. The PNY drive was actually in 12th place on the 350MB file test, here we see it moved up a few spots to number eight on the list.
Next is the Read From test:
Again the OCZ Throttle drive is number one, still the top five drives are all very close in performance for this test. Again the ordering has changed from the 350MB file test.
and finally here’s the results for the Copy From test:
and yet again the OCZ Throttle drive is in the top spot, and one thing has remained the same for all of the tests I think, the worst is still the worst no matter how you look at it… anyone want a Transcend drive?….
Seriously though, if I had a choice of these drives it would be the OCZ Throttle, but then again it might not be. Yes it’s the fastest of the bunch, but it’s a hybrid drive, it’s got both eSATA and USB connections on it, and to use the USB connection you need to carry a small USB cable with you with mini-USB connector to plug into the Throttle, to me that’s a bit of a hassle really. The next choice would be tied between the Kingston HyperX and the Patriot Exporter XT drive, both are fairly fast and both have good qualities in their construction as well. Then again why would I bother with 16gb drives when I’ve got 32gb and 64gb ones on hand?
If I’m looking for a USB drive, the first thing I look at is the Copy To or Write speeds, this is what is most important to me, the next thing would be the Copy From speeds, as for me what I do most is put data on it, then take it off, reading from the drive is not that important to me really. So it all depends on what your priorities are concerning USB drives, the results are here, you can judge for yourself which is best for you.
If I had to give an ordering for the top three drives, taking everything here into account ,including my preferences, it would have to be the OCZ Throttle coming in first with the Kingston HyperX in second, the Patriot Xporter in third. Those are the ones that I would buy personally.
I hope you enjoyed this, I had fun doing it, I’ve got an even larger one in the works as well, but it’s going to be a bit different, so be on the look out for that within the next couple weeks.
