What customers say about "Key Specs"
ADATA SU900 128GB Ultimate 3D NAND MLC 2.5 inch Internal Solid State Drive - Black
  • Easy to install and setup. Gave my 7 year old Mac a new lease on life! Very impressed. Great quality. Great value.
  • Not the fastest but its stable and gets my work done! I do recommend this drive.
  • Very happy i got the larger GB size, it installed fine and i have the extra room for more games now. I see nothing wrong with this hard drive. It works perfectly fine.
  • This was the best value I could find online or in-store for an SSD. It was large enough to replace the HDD in my laptop without having to sacrifice storage space.
  • Not the best read and write speeds, but for the significantly cheaper price tag id say it's a good option for those wanting a budget SSD.
Samsung 860 EVO 250GB 2.5" Internal Solid State Drive
  • Took about 30 minutes to make the switch and be up and running. It's faster than I anticipated and am very pleased with this purchase.
  • Slim design and easy install. Setup in disk management on windows is a snap...highly recommended.
  • Installation was a snap and coupled with enhanced RAM this new SSD cut boot time tpo a fourth of what it had been.
  • I think Samsung SSDs are one of those having the greatest compatibility to various systems and quality and durability.
  • This is quite a boost in startup time in Windows 10. Took a quiet a few restarts to train it seems like but now it starts up so fast.
  • Only issue would be the price but if you get this on sale, then it is a great deal.
  • No instructions, no cables, doesn't even tell you what cable you need. PC will not recognize it.

What customers say about "Features"
ADATA SU900 128GB Ultimate 3D NAND MLC 2.5 inch Internal Solid State Drive - Black
  • Some Trim painfully slow. Luckily this nice 3D NAND SSD works very well. I got the 128GB SU900 model. Specs show it to be virtually as fast as the larger capacities.
  • The biggest advantage of this product is that it is a 3D MLC NAND SSD. It is known that MLC has a longer data cell life than TLC, so it can be satisfactorily used.
  • This SSD has read and write speeds at what they advertise. The great thing is, if you are upgrading from an older drive ADATA gives you Acronis True Image.
  • Major gripe is SSD Toolbox software not compatible with SU900. The support responds quickly to your queries, but their response is pointless and does not help.
Samsung 860 EVO 250GB 2.5" Internal Solid State Drive
  • This thing is great! I used the Samsung software and cloned my old drive and then boom, like a whole new computer!! Startup takes seconds instead of 15 minutes like it used to!
  • Laptop boots up in 8 seconds.. all programs and downloads have increased approx 80 % !! amazing.
  • Bought this for gaming, and programs start about 30% faster with no stuttering during gameplay. The 1 TB is a must to start, but might add another SSD in the future.
  • Data access is liekwise much faster, programs boot up much more quickly and it's almost like a new laptop rather than over 6 years old.
  • My Mac used to take around 3 minutes to boot. Now with the SSD, I clocked the boot time at 25-28 seconds, the desktop, applications appear immediately.
  • These drivers are to terrible. Samsung's own magician software doesn't even recognize either drive.
