AI-generated summary
If you’re buying a Lenovo internal 3.5" NL-SAS drive for server use, this is the kind of “keep the lights on” storage that makes sense when you *don’t* need top-end performance. The 14TB capacity at this price (around **£964 ex-VAT**) is broadly in the right zone for bulk storage—assuming you’re actually using it for backups, archive, capacity pools, or general RAID workloads where latency and IOPS aren’t the main goal. It’s also a sensible fit if you’re standardising on Lenovo hardware and want predictable behaviour with the rest of your platform.
That said, I wouldn’t buy this if your priority is speed (random I/O, fast rebuild times, performance-sensitive apps). NL-SAS is typically chosen for cost-effective capacity, not snappy performance, and you’ll feel that in more demanding workloads. Also, check compatibility and support expectations in your specific server/chassis/RAID controller—drive part numbers matter more than people think, and you don’t want a “it fits but it won’t behave properly” situation. If you tell me the server model and whether this is for RAID for production data or for backups/archival, I can give you a clearer go/no-go.
