I own several of these devices. They are well designed, with the USB connector retracting into the body. The loop at the end is strong and will not break easily when carried in your pocked on a keychain.(Be sure to use the little ring included with the package to attach it.)

Read and write speeds are adequate. Some people have claimed that this particular unit is slow. I don't really understand what they are talking about. I routinely transfer several gigabytes of data to one of these units and it doesn't appear to take an unseemly amount of time. One has to wonder if the complainers aren't overlooking some other factors, such as a problem with the Windows copy process which is inherently flawed and that I never use for transferring large amounts of data or a great number of files. You are much better off using BeyondCompare or any number of other utilities for such tasks.

These devices often to on sale, so you might be well served being patient and waiting for such a sale.

Overall, I think these are terrific bargains and absolutely great for transporting significant amounts of data.

I was impressed with the previous 2Gig transcend model 110. I bought this one, thinking that it was going to be just as quick.
I was wrong. It is horrible with writes. 8GB models are a different technology from the 2Gigs models and probably the 4GB, too.
I am going to stick with SanDisk 4GB Titanium until I can find a review showing that 8GB devices are worthy. I think Transcend is a fine company, but they release leading edge products that should remain in the Q&A labs.

I will call them and see if I can get a replacement or credit.

Of course the drive has large capacity. But it is the SLOWEST USB 2.0 flash drive I have ever used. It took over 2 hours to transfer 4 GB of small photo files from my hard drive to the JetFlash, with no other applications running in the computer

I purchased one of these in April 2007 to replace my SanDisk 4GB U3 Cruzer that would not work with Vista. While the Transcend 8GB JetFlash V10 does work with Vista, it writes exceedingly slowly. I benchmarked the two Flash drives and came up with the following (Cruzer followed by V10):

Small File (1mb) Write: 2.391 - 6.532 seconds
Small File (1mb) Read: 0.672 - 0.938 seconds
Large File (10mb) Write: 17.656 - 22.594 seconds
Large File (10mb) Read: 6.813 - 6.281 seconds
File (20mb) delete: 0.110 - 1.953 seconds
Directory Lookup (10,000 files): 13.047 - 11.938 seconds
Overall Write Speed: 5,462 - 811 KB/second
Overall Read Speed: 31,723 - 30,883 KB/second

Overall, the read speeds are comparable, but the write speed on the V10 is significantly slower. Slow enough in fact, that the V10 is not fast enough to support Vista's ReadyBoost although at least it works as a Flash Drive in Vista while the older U3 Cruzer doesn't work at all with Vista (newer U3 Cruzers are Vista compatible - be sure the firmware is recent).

I purchased one of these about a year ago. The price for an 8MB Flash Drive looked like a fantastic deal at that time. The cliche "You get what you pay for" now comes to mind. I have owned at least six different USB drives over the last three years and this is by FAR the slowest of any of these many times over. 8MB is a lot of storage, but it takes FOREVER to write large files to this drive. I would strongly urge anyone considering this drive to spend the extra money for a faster high capacity drive if you will be copying large files to the drive on a regular basis. I regret trying to save money with this drive. It's really that slow.

This USB flash drive may be cheap, but it is also very slow, especially for one so big. If you need to carry an incredible amount of data with you that you hardly ever access and almost never change, then this might be for you. But, for the average user, the manufacturer says: System Performance Read 10 MB/sec Write 2 MB/sec. This is very slow, compared to any modern high-performance drive. My OCZ Rally2 4GB has an impressive 23.8MB/s average read speeds, 14.8MB/s write speeds. The Corsair Flash Voyager GT is even faster at read speed of 33.8MB/s. So buyer beware!

This unit works fine, no problems with it. The shipping time was great too.

So i bought this VERY cheap and then found out it was DEAD SLOW! I mean it took near 30min to transfer 500mb of photos. However, after fooling around with it i larn that its not the drive that's slow, its the software it comes with! DON'T USE IT! I formatted the drive and used the old method of dragging files right to the drive ... works perfect.

I bought the Hi Speed USB flash drive cause I thought it was high speed since the name said that.Instead it was very slow and took 1/2 hour to add files to it. I had to return it and bought a Corsair 8 GB USB 2.0 The specs. are: Write 34 MB/s Read 28 MB/s for about double the price but it is probably 4 X's faster.

For the price and how much it holds is great! But the drive is oh so slow.
But again, I have several of these type of drives by different manufactures and they are all slow. If you need the sapce and have the time, buy it you can't go wrong!
