What customers say about "Features"
ADATA SP920 1TB 2.5" SATA III Solid State Drive
  • Amazing SSD. I have had no problems from it.
  • This SSD works great for gaming very fast.
  • Works, great value, and fast. Easy to install.
  • The boot up is crazy fast! Great performance and encryption.
  • Installation was super easy and everything went smoothly.
Samsung 850 EVO 500GB 2.5 inch Solid State Drive
  • Uses normal SATA III interface and was recognized by computer with no problem.
  • If your system supports SATA 3 only, you won't be disappointed with this; I personally bought a few, and never had an issue with any of them.
  • Very fast SSD and offers 256-bit encryption, I cannot find a better SSD than this one.
  • The 32-layer 3D VNAND flash memory ensures reliable performance, and AES 256-bit encryption keeps my data private.
  • No reduction in start-up time. Still takes about 20-ish seconds. Not bad, but I don't understand why there isn't at least a little improvement.
