Lenovo 4XB7A77447 internal hard drive 4 TB 7200 RPM 3.5" Serial ATA III

Product Overview

AI-generated summary

For £601 ex‑VAT for a 3.5" 4TB 7200 RPM SATA drive, this is only “good value” if you specifically need capacity on the cheap and you’re buying in bulk or dropping it into an existing 3.5" SATA server/NAS chassis that already runs on spinning disks. In that scenario, it can make sense: the performance is what you’d expect from 7200 RPM drives, and it’s straightforward to deploy. If your environment is mostly sequential workloads (bulk storage, backups, archives, media servers, general file storage), you’ll likely be happy.

That said, I’d be cautious if you’re buying this for anything that needs lots of random I/O (databases with heavy read/write churn, virtualisation hosts, VDI). In those cases, SSDs (or at least a cache/boot SSD strategy) usually pay for themselves in responsiveness and reduced operational pain. Also, price matters here: if you can get comparable capacity SATA drives from the major OEMs at a notably lower street price, you’ll probably get the same real-world outcome. My honest take: buy it only when you’re confident you want/need HDD capacity on SATA, and you’re not expecting “fast” in the SSD sense.

If you tell me what it’s going into (server model/NAS vs workstation, RAID level, and workload type), I’ll say whether this price is actually sensible or whether you should steer toward something else.
