Adata Ultimate SU800 SSDs use floating-gate 3D NAND

— 10:09 AM on August 25, 2016

Adata is bringing out a new series of Ultimate SSDs today, spearheaded by the SU800. These 2.5-inch SATA drives will come in capacities from 128GB to 1TB, and they'll use 3D TLC flash memory. That density should Adata to keep costs down and prices low. Adata says it's using 3D floating-gate flash in the SU800, a strong suggestion this drive is using the same Micron 3D NAND we saw in Crucial's MX300.

Alongside that TLC NAND, Adata's SU800 SSDs use both a DRAM cache and virtual-SLC mode to improve performance. Unfortunately, the company only provides numbers for sequential performance, but the specified 560MB/s read and 520MB/s write speeds are encouraging. The company claims the drives provide "high" TBW ratings, although curiously, it doesn't give actual endurance ratings. Adata does specify two-million-hour mean-time-between-failure ratings, though, and offers a three-year warranty.

Of course, the real news about these drives is the pricing. Adata suggests a price of $269 for the 1TB model. That's not a bad price for a 1TB SSD to begin with, and street prices will surely be lower with time. Adata says the SU800s should be available immediately from Amazon and Newegg, although they aren't listed the time of this writing.
