Lenovo 4XB7A80354 internal hard drive 20 TB 7200 RPM 3.5" Serial ATA III

Product Overview

AI-generated summary

For £1,685 ex-VAT, a 20TB 3.5" 7200RPM SATA drive needs a very specific job. If you’re trying to build or expand a NAS, archive array, or “bulk storage that doesn’t need fancy performance” kind of environment, it can make sense—assuming your controller, backplane, and warranty/support situation are solid. That said, at this price point you’d want to be sure you’re not paying a premium for the brand label when comparable-capacity drives (or even enterprise refurbs) could get you more storage per pound. In day-to-day UK SMB deployments, people usually buy these when they’ve done the maths and know they want spinning media at scale, not when they’re chasing speed.

Who I *would* recommend this for: businesses with 3.5" drive bays, SATA backplanes, and a clear need for capacity—think backup targets, media stores, lower-intensity file servers, or cold-to-warm archives. Who I *wouldn’t*: customers hoping to turn this into a performance upgrade, or anyone with a drive budget constraint who’s still comparing “£ per TB” without considering downtime risk, rebuild time, and support. Also, make sure it’s the right mix for your workload—if you’re doing lots of random I/O (databases, heavy VM storage, busy shared storage), these kinds of drives can feel slow and generate more wear than people expect. If you tell me the use case (NAS? server? number of drives? RAID level?), I can say whether this is a smart buy or just an expensive way to store data.
