Last week, ADATA announced its new inexpensive lineup of SATA SSDs: the new Premier SP580 drives use Marvell’s 'Artemis' controller aimed at value storage, as well as TLC NAND flash from SanDisk.

The new ADATA Premier SP580 family consists of two models, with 120 GB and 240 GB of TLC NAND produced using 15 nm process technology by SanDisk. The new drives are based on the Marvell 88NV1120 controller and do not use DRAM cache, which lowers their cost and puts them further into the cheap SSD category: DRAM-less controllers are expected to populate the low-cost segment over the next year. The manufacturer declares 560 MB/s / 410 MB/s maximum sequential speed for the 120 GB version of the SP580 SSD. ADATA notes that the 120 GB version is slower than the higher-capacity model, but does not elaborate as to the 240GB specification. Keeping in mind SATA performance limitations and how these drives work, read performance of both Premier SP580 SSDs should be similar, but expect the 240 GB model to offer slightly better write performance.
