Quality score

How we score →

Scored from recording type (CMR or SMR), workload rating, warranty, measured failure rate where Backblaze covers the model, spindle speed, MTBF and cache. Use class and size filter; they never score.

Value weighs the score against the price, compared with other 6TB hard drives: this drive costs $55.00/TB against a typical $51.15/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 hard drives with each other.
