If you are looking for a 2.5″ SATA 6Gb/s internal solid state drive, then ADATA has quite a few similar products to choose from.
This Seeking Tech guide will help you differentiate the SU630, SU635, SU650, SU655, SU720, SU750, SU760, SU800 and SU900 models.
Quick Summary
When compared to the other ADATA Ultimate Internal SSDs, the SU900 have the fastest maximum sequential write speed and tied (along with the SU900) for having the fastest maximum sequential read speed. With that said, the differences aren’t really substantial.
In terms of durability, the SU900 is mostly the same as many of the other solid state drives in this comparison guide. However, the SU900 does have a potentially longer warranty period of 5 years as opposed to 3 years.
So, if you want the best performance and longest warranty coverage, then the SU900 is the best option available.
If you don’t mind losing out on the extra two warranty years, then the SU750, SU760 and SU800 offer similar read and write speeds at more affordable ranges.
