Adata's Premier line makes up the majority of the company's SSD offerings, and the baseline SP550 is frequently among the best-priced SSDs around. Another member is joining that family today: the Premier SP580 SSD. This budget SSD is equipped with TLC flash, a Marvell controller, and a SATA 6Gbps interface. Adata is quoting sequential numbers of 560MB/s for reads and 410MB/s for writes. As we've come to expect for budget drives, Adata doesn't specify random I/O performance.
Performance like that won't set anyone's hearts alight, but the marketing for this drive emphasizes that it is suitable for "any" computer, which we think suggests a very low price. The new drives support a "simulated SLC" mode, which should help performance in some cases. We reviewed the Premier SP610 back in 2014, and found it to be exceptionally power-efficient, a quality that Adata is also promoting for the SP580. The company claims the disk uses 0.5% of the idle power of a hard drive. Adata didn't specify pricing or availability for the new drive, but it will be offered in 120GB and 240GB capacities.
