WD Ultrastar DC SN640 prices — used NVMe SSD
WD's PCIe 3.1 NVMe data-center SSD, mostly sold as U.2 drives. Prices include shipping. The low end and the median use single-drive, fixed-price listings only, so multi-drive lots, auction bids and parts-only listings can't skew them. The low end is the 10th-percentile $/TB: one in ten listings ask that much per TB or less, so it's a price you can find near the top of a search sorted by price. The median is shown beside it.
As of October 1, 2026, used WD Ultrastar DC SN640 drives cost $155/TB shipped at the low end of eBay's market: one in ten of the 24 live single-drive listings asks that much per TB or less. The median ask is $182/TB. The low end was $163/TB on Aug 3, so it's down 5% since. The most-listed capacity is 7.68TB, where a drive costs $1,159 at the low end (one in ten of the 18 single-drive listings at that capacity asks that or less) and the median ask is $1,375.
