How this table works

We collect Buy It Now listings from eBay US several times a day and divide the total price, including shipping, by the capacity. Health is the remaining-life figure the seller states in the title (when a range like "90–98%" is given, we show the lower number). We remove external and USB drives, hard drives listed as SSDs, "box only" listings, multi-size listings, unbranded drives and capacities that real SSDs are not made in — a common sign of counterfeits.
