Quality score
How we score →Scored from what the maker publishes: cache, capacity (under 1TB loses points), endurance per terabyte and warranty. Every SATA drive is capped by the same connection, so speed does not count.
Value weighs the score against the price, compared with other 500GB SATA SSDs: this drive costs $503.62/TB against a typical $221.90/TB. At a typical price, value equals the score. Cheaper raises it and dearer lowers it, but price counts for less than quality.
A factor we hold no value for scores zero rather than being skipped, so a drive we know little about never outranks a fully documented one. A low score with low confidence means undocumented, not bad. This is a specification index, not a benchmark, and it only compares SATA SSDs with each other.
See every capacity of the WD Red SA500 on one page, or compare it with every other drive on the SATA SSDs table.
