Buying a second-hand SSD should be as simple as getting an email.
Every morning a system goes through Wallapop and Kleinanzeigen, keeps the new NVMe SSDs that fit what you are looking for —M.2 or U.2, consumer or datacenter— and emails them to you, ranked and explained: what others ask for the same drive, how much you pay per TB and per TBW, and what the listing says about its health. And below, what happened in storage: launches, NAND prices, reviews. No accounts, no app. Just email.
Write to
Which SSD you are after (one or several: "a 990 Pro or an SN850X", "a PM9A3 or a Micron 7450"), or what it must have: capacity, PCIe generation, form factor (M.2 2280, 22110, U.2), DRAM, TLC; your budget (each, or in €/TB), where you live or whether you want it shipped, and what you won't do without: invoice, warranty, stated health. If you just want to keep up, say so: "news only".
What you get
One email a day with the new SSDs that fit best, and a weekly roundup on Sunday. Each with its price, model and capacity, interface and form factor, whether it has DRAM or is QLC, its endurance (TBW) and, for datacenter drives, power-loss protection; where it is and whether it ships, and why it is on top: below what others ask for the same drive, the day's best price per TB, new, with invoice or warranty, SMART data shown, or a price drop. And what doesn't add up, flagged: pricier than other listings, too cheap to be true, QLC, or already through a good part of its TBW.
Whole PCs and laptops, empty enclosures, adapters, bundles and SATA drives (unless you ask) don't make it; broken drives neither; the same drive listed twice arrives once; and what you've seen doesn't come back, unless it gets cheaper. The news comes in your language or in English, and the same story told by several sites, once.
