  • Don’t take your computer apart - use this USB-connected SSD, to get the best bang for the buck!
Works great. Excellent value. I’m using as an external, USB-connected, MAC boot drive, also performs well on Windows PC. I have an iMac that is one sealed unit and is virtually impossible to get at the internals to update, so I can’t replace the internal hard drive - but using this SSD externally is a solution that gives much, much faster performance. ... show more

  • Good Product
Capacity: 256 GB Color: Black
I have not tested the water proof aspects, but I will say that this product handles my large indesign and Illustratior files with ease. There have only been a couple times when I have over six large files open where I start reciving lag off of it. However this is my fault and I can feel the ssd becoming very hot trying to work all of these files. As far as transfering data, everything works perfectly! ... show more

  • Four Stars
Problem with the wire and the connection to the SSD: very fragile, lost of contact.

  • Fast, reliable, durable
Capacity: 512 GB Color: Black
love that its sturdy, durable, rubber edge seems well enough to protect it from major (falling) shock damage, and it comes with a high speed USB cable. its quite small compared to other external hard drives I've used. Haven't had any issues with it.

  • Spectacular data failure
This review will be ongoing and is subject to change as I investigate the problem. We were using this drive as a more secure method of storing critical data for a doctoral degree. The device has had three spectacular failures. First, a word file suddenly reverted to an outdated replaced version of the same file, losing all work done on the file for a period of about 1.5 days. Second, the same kind of error occurred, losing a couple of hours of work. These first two losses we guessed might have been caused by some kind of very strange behavior on the part of Windows or MS Office, though as a programmer of several decades I could not quite imagine how. The third loss was the complete disappearance of a folder. just created the day before. We've used countless USB drives, and never before encountered such errors,. Not even old hard drives with failing sectors were able to create such insidious failures. My phone call to customer service was met with contempt for my intelligence, with the operator telling me these drives never fail and the error was surely a software error. He said I should try a flash drive and see if I have the same problem. Quite frankly, using someone else's drie was exactly my solution too, though I would have loved to speak with a little brighter light within the adata company in hopes of learning what kind of error this was, and anything adata knows about the problem. Having read this review, if you still want to put your data on this drive, all the best! ... show more
