Western Digital
WD Blue SA510
SATA · 2TB · Released May 31, 2022
As the only SATA drive among these four Western Digital models, the SA510 caps out at 560/520 MB/s sequential and around 89K/75K random IOPS, limits set by the SATA interface itself rather than the controller. Endurance sits at 700TB written, the lowest figure in the WD Blue/Black lineup, backed by the same 5-year warranty as its NVMe siblings. It suits older systems or budget builds where a motherboard lacks NVMe slots, where raw NVMe speed was never part of the equation.
