Summary: This is third one of these I own. I just got another one for my smart TV. This drive writes at 13MB/s with many files approx 4MB each, and 16Mb/s with a single large file. It reads at 30MB/s. For comparison, 100MB LAN operates at about 11MB/s, and laptops copy files at about 26MB/s, so this drive can keep up with standard usage. Above average performance. I like the slim compact design. I have noticed some delays after writing files for refresh to complete.
Summary: I purchased this item based on the reviews and the claims of speed. I just got it and quickly did some basic tests copying several files ranging between 40MB to 1.6GB from my hard drive to this pen drive. The pen drive is connected to a powered USB hub, not directly to the computer. The speed indicated by Windows (7 64-bit) while copying goes between 14 and 20 MB/s. I found this speed to be more than acceptable.
Summary: I use a thumb drive to replace what I once used a portable hard drive to do - mainly backup important files frequently and keep them with me wherever I go. You never know when you might stagger into a library and need to take a quick listen to your latest pirated music collection! So far, this drive has plenty of space left for files but I do notice that smaller files take longer to access compared to my previous drive (a 4GB Transcend).
Summary: I needed a 16 GB USB drive for shuttling around files over an air gap. Wanted something faster, and ended up looking at the JetFlash 600 and a few others. Glad I went with the JF600- the drive has been reliable and very, very fast. Write speeds around 16-20 MB are common. My only complaints are a somewhat flimsy case and the removable (and losable) cap.
Summary: My last USB failed, but i got a great deal of use out of it. I decided to go for one that was a little more expensive, but it has been worth it. I download and back-up most of my programs and files and have been able to add much more information on this USB. Its packaging is small and easy to get into, which is a great plus in my book. Easy entrance of use. I have stored it for use in my bag and forgotten it for weeks on end. Each time of use, it is easy and efficient.
Summary: Love this flash drive. The simple black and small look is cool and clean, and to make it better the blue ring light around the rim when plugged in makes it look professional in my eyes. The read and write speed is good enough for me. I'm not a anal and picky person on that, but it sure goes fast and works just great! Only one thing I found I didn't like, was right when I pulled it out of the plastic. The drive is actually really light plastic.
Summary: I've been using this 64GB flash drive for my work. I use it on PCs and Apple machines. I even plugged it into a Mac OS 9 computer and it rebuilt the Desktop DB for it and mounted. That was great! It seems pretty bullet proof so far and the size really saves me a lot of 'download' time especially on software and OS updates that are hundreds of MB or even 1GB+. I'm not real shure about the actual thoroughput of the device for it seems like regular USB 2.0 speeds.
Summary: Great price for a 32 GB flash drive. I tried it out and it took about 40 minutes to offload 28 GB of pictures and video, so I am not sure if that is a fast speed. The flash drive is very small and looks real nice in black. It feels very fragile though, so I would recommend being careful with it and maybe placing it a little bubble pouch when carrying it around. For the price, you can't beat it.
Conclusion: Haven't used it a whole lot yet, but the price was great for the 32 GB storage size. If it's as fast as it's supposed to be, I'll be very happy. Very slick design too. My only complaints are you can't put the cap on the back end for storage while it's in use and it's a bit wide so it interferes with the neighboring USB port on my MacBook Pro.
