Manufacturer description
The ADATA Ultimate SU800 1TB brings 3D NAND flash to the 2.5-inch SATA III form factor, and it is aimed squarely at the upgrade you keep putting off: pulling a mechanical hard drive out of an aging desktop or laptop and giving it a second life. ADATA rates the SU800 at up to 560 MB/s sequential read and 520 MB/s write, which saturates the SATA III interface and turns multi-minute boots into seconds-long ones. A DRAM cache buffer paired with dynamic SLC caching keeps sustained writes from collapsing the way DRAM-less budget drives do, so large file copies and game installs hold their speed…
SpecPicks Verdict
SpecPicks scored ADATA USA Ultimate Su800 1TB 3D Nand 2.5 Inch SATA III Internal… using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. ADATA's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
How fast is the ADATA SU800 1TB?
ADATA rates it at up to 560 MB/s read and 520 MB/s write, which is effectively the ceiling of the SATA III interface it uses.
Will this SSD fit my laptop?
It is a standard 2.5-inch SATA III drive, so it fits any laptop or desktop with a 2.5-inch drive bay and a SATA connection. It will not fit an M.2-only slot.
Does the SU800 have a DRAM cache?
Yes. ADATA pairs a DRAM cache buffer with dynamic SLC caching, which is why sustained write performance holds up better than on DRAM-less budget SSDs.
What warranty does ADATA include?
The SU800 carries a 3-year warranty. Check the product listing for current terms and regional coverage before purchasing.
Is the SU800 a real upgrade over a hard drive?
Yes. At up to 560 MB/s read versus roughly 100-150 MB/s for a typical mechanical drive, boot and load times drop from minutes to seconds.
