I'm putting together a storage-focused PC using a spare case, motherboard, and some RAM, with plans to add an optical drive and SD card reader. New 2 TB drives are unusually expensive right now, so I'm considering buying preowned hard drives or M.2 SSDs instead. How risky is that, and what should I check before using one?

Buying used drives is basically a gamble unless they’re part of a setup with redundancy and parity. If you do take the chance, test the drive thoroughly, keep backups, and treat it as expendable. A good deal isn’t worth it if losing the drive would also mean losing your only copy of something important.
For hard drives, check the SMART data and scan for bad or unstable sectors before trusting them. Hard drives can last a long time, but a drive with lots of bad sectors or unusual noises should be avoided. Make sure the discount is large enough to justify the risk, and never rely on a single copy of important data.
There are two separate concerns. As a precaution, wipe and format any used drive before loading your operating system or personal files. The bigger issue is remaining lifespan: SSD wear can be difficult to judge, and a heavily used flash drive may fail or become read-only with little warning. I’d avoid used SSDs for important data, though one could be acceptable for replaceable games or downloads.
Used SSDs can be a reasonable purchase if the price is low and the health data looks good. Check CrystalDiskInfo for total host writes, remaining life, power-on hours, and any warnings. A lightly used drive with a substantial discount is much less concerning than one showing heavy usage.
That makes sense. I’ll probably only consider a used drive for replaceable files and keep anything important backed up elsewhere.
