What customers say about "Key Specs"
  • It has not failed yet. I have it set up as mainly my OS drive and I have another HDD for storage. It's fast and makes windows 10 run smooth.
  • Great drive. Works well, and is very fast.
  • Very affordable price for the quality of this SSD. Pc starts up like a dime running windows 10 off of this ssd.
  • This SSD seemed to be great value so gave it ago, installed it without any difficulties and is working great (early days), laptop feels more responsive with boot up times into Windows 10 noticeably improved.
  • Adata's RMA process is a hassle, and YOU pay return shipping. The SU650 120gig is likely a defective model, and I think Adata knows it.
  • This drive has failed at multiple locations for us. Go with the blue labeled drives by Adata instead. this drive definitely has a problem.
ADATA SU655-1 480GB 3D NAND 2.5 inch SATA III
  • So far, so good. easy to install, did a fresh Win10 home install. Sequential read/write speeds seem spot.
  • Super fast, easy to install and it’s one of the cheapest nvme ssd out. If you want a good middle ground, this is perfect.
  • Quick product. Works reliable and fast and seems go have no weird bugs like some china alternatives, 10 out of 10.
  • If you're just looking to upgrade your slow hard drive and move into the world of blazing fast solid state drive technology, this will get your foot into the door and more.
  • This disk is overheating, then again, the case is made of plastic and plastic is not really heat conductive... I will probably remove it from it's plastic cover to help it.

What customers say about "Features"
  • ADATA SSDs have always been my first choice. ALWAYS AS FAST AS ADVERTISED!!! NO FAILURES.
  • It doesn't have the look or feel of a premium product, packaging is adequate and the drive itself is best described as hollow feeling plastic, don't let this put you off - it comes across as a good value product.
  • Very fast boot up times of around 36 to 40 seconds on my system, with no loading or stutters from apps once on the desktop, ready to go once desktop is loaded with instant performance :)
  • I set it aside for a year and a half not needing it after all. Now that I do need it, it is dead.
ADATA SU655-1 480GB 3D NAND 2.5 inch SATA III
  • Great drive. Great value! Installed it on an 8 year old laptop running windows 10. And it boots up relatively instantly! Easy to install.
  • Works great on PC, but some macbook pros it wont work on properly it freezes and wheel appears. but in linux it works fine.
  • Working great, quick game load times, no problems whatsoever, doesnt run hot. Only con is I wish I had a couple more =D
  • Installed windows 10 on this (as well as a few programs) and the boot speed in insane! Way faster than a SSD, totally worth the cost.
  • Extremely fast boot time. I installed this with a new mother board as my boot drive. From power button press to Windows 10 log in screen in 19 seconds.
  • Shows Disk Failure, i took it out and put it again a couple a days later the same message disk failure.
