Lenovo 01KP040 internal hard drive 900 GB 15000 RPM 2.5" SAS

Product Overview

AI-generated summary

For £706 ex-VAT, a 900GB 2.5" SAS drive spinning at 15k rpm is basically a “performance tax” you’re paying for random I/O, not capacity or cost-per-gigabyte. In the real world, these are the right kind of drives for older SAN/NAS servers, virtualization hosts, or database workloads that genuinely benefit from low-latency reads/writes (think heavy VM storage, transactional DBs). If your chassis/controller is already set up for SAS 2.5" 15k drives, this is the sort of like-for-like replacement that won’t force changes to firmware, caddies, or drive backplane compatibility.

That said, I wouldn’t buy this just to “get more storage for less.” At this price point, you’re usually better off sizing whether you actually need 15k behavior—modern SSDs often give far better responsiveness and can be cheaper once you factor in power, cooling, and the opportunity cost of slower storage. Also, if the system isn’t already configured for SAS performance (or if your workload is throughput-heavy rather than latency-sensitive), you may not feel the difference. Bottom line: buy it for mission-critical, low-latency workloads where the platform expects 2.5" SAS 15k drives; think twice if you’re buying primarily on storage volume or budget.
