Fantastic speed and durability! Still zero problems with it and it has been both speeding up computer with ReadyBoost as well as acting as mobile storage for large IT utilities and user data. I have stored everything from training videos (about 400 hours of them from CBT Nuggets) to my computer repair utilities to my full music library on this drive. As others have stated, the "positive locking" of the extended port plug is invaluable, especially for someone like me who is all thumbs!Additionally, like mentioned in the other reviews, this drive is capable of lightning fast file transfers... IF the files are singularly large. What I mean by this is:1,000 files that are each 1Mb in size each for a total of about 1,000,000Mb (or roughly 1GB) may take lets say 20 minutes to transferor1 file that is 1Gb in size may take only 5 minutes to transfer.The reason is because every time your computer finishes transfering file contents, it has to close that file, then create a new empty file, then open that file for editing, then transfer the contents, and repeat. If you have fewer files that are larger, then you will see more of the speed benefits of this drive.Also, as stated by other reviewers, if you plug this drive into a USB1.1 or USB2.0 port, you will only get the best possible speeds for that port, so don't blame this drive for slow response times on an old port. Upgrade to USB3.0!As far as if you have any issues with this drive being recognized on one computer, but not another, well, that is in the realm of the computer, not this drive. This drive utilizes a common USB (Universal Serial Bus) driver developed for USB3.0 devices. So if you have this issue, scan your computer for malware first. If that doesn't solve the problem, try another USB port on the computer until you go through them all (Try the port your USB mouse is plugged into!) If that doesn't work, ask your local computer tech (child, friend, co-worker, etc) to fix the issue. If it is software, it usually just involves deleting the bad driver so the computer redownloads it. Or you may just need them to install a new USB card in the computer and presto problem solved!
