A bit of background information: I own both the Sandisk Cruzer Micro 4GB and 16GB versions. What I noticed is that the 16GB version is much slower than the 4GB version, especially when witting data. I even contacted Sandisk customer support, trying to find out what is the speed of Cruzer Micro. The response I got was quite useless:
"There is no guaranteed speed for SanDisk Cruzer Micro flash drives, as the speed for these flash drives have not been tested. If you need a flash drive with fast data transfer speed, we recommend SanDisk Extreme Cruzer Contour for this."
Prior to ordering this JetFlash drive, I visited the Transcend USA web site to search for information. Surprise, surprise! The data transfer speed of JetFlash 500 (under the 'V' series) is actually specified as:
"Read 15 MByte/s, Write 7 MByte/s (16GB)"
Once I received this Transcend JetFlash drive, I put it through several benchmark programs, to compare against the Sandisk Cruzer Micro:
- For typical photo files, write speed of the Transcend varies from 6.8MB/s (for 1MB file) to 11.3MB/s (for 5MB file). In contrast, the Sandisk only ranges from 2.0MB/s to 3.5MB/s. That means the Transcend is about 3x faster than the Sandisk! (See my Customer Images for details)
- For very large video files, the Transcend writes at about 7.8MB/s, while the Sandisk only reaches 5.1MB/s. The difference in smaller but still significant.
In terms of storage space: The Transcend drive reports 15.1GB of total capacity, while the Sandisk drive reports 14.9GB. Note that it is normal for a '16GB' flash drive to show only 14.9GB of storage, because 14.9GB for computer people (where 1GB = 2 to the power 30) actually translates to about 16,000,000,000 bytes. So that can be called '16GB' according to marketing people (where 1GB = one billion bytes).
In summary, the Transcend JetFalsh 16GB drive looks and works just like the Sandisk Cruzer Micro, but its write speed is +50% to +200% faster than the latter. As of this writing, both drives are available at similar prices, so this makes the Transcend a much better value.
[Update on Nov 3, 2010]:
- The price of this Transcend USB drive dropped further during the past two months. So now it is an even better value.
- Several reviewers have reported bad experiences using this USB drive on the Xbox 360. Right now your only safe bet is to get the Xbox 360 - 16 GB USB 2.0 Flash Drive by SanDisk, which costs twice as much.
- If you don't intend to use the software supplied by Transcend, simply rename the file "Autorun.inf" (located at the root directory of this drive) to something else, such as "Autorun._inf". Then you can use it as a simple USB storage device.
[Update on April 7, 2012]:
I have my Transcend USB drive connected to my desktop PC as secondary storage most of the time, only occassionally remove it to transfer files. So far it worked perfectly fine for 1.5 years. It should be noted that I have used at least half a dozen USB drives and at least 20 flash memory cards in the past decade, and none of them ever failed on me. So it could be that I am just more careful with semiconductor devices (I always discharge myself of any possible electrostatic charge before handling memory cards, for example)
Not much you can say about storage other than it's fast and dependable with free software to help make your life and work easier. It's a nice looking little unit and I really like the way you simply slide the connection out.
UPDATE: I accidentally left my Transcend in my jeans and washed them. I'm pleased to report that the Transcend manned up and worked as well as before it took a bath. While I don't recommend this sort of treatment, it's good to know this little guy can take a bit of rough treatment.

According to USBDeview the speeds for this device are approximately 7MB/s for write and 15MB/s for read. A bit on the slow side, so if you're going to be moving tons of data on & off this device on a regular basis it might get on your nerves. Not a huge deal for me, but to each their own!
