If you’re paying **£2431.97 ex‑VAT for an 8TB WD_BLACK SN850X**, you’d better have a very specific reason: sustained NVMe performance for heavy workloads. This drive is the sort of thing you buy when you’re doing real “IT” grunt work—think workstations running lots of large assets, build servers compiling constantly, data processing scratch space, or a high-end gaming rig that will happily eat drive bandwidth. The **encryption support** and **heatsink** are practical touches: it’s less faff than retrofitting cooling, and it’s genuinely helpful if you’re running sustained writes where thermals can become a bottleneck. In that context, it can feel like good value because you’re buying fewer problems, not just raw speed.
That said, **I wouldn’t recommend it for most businesses** unless you already know you need this class of drive. If this is mainly for general file storage, VDI boot images that don’t churn, or “we just need capacity,” you can almost always get better cost-per-GB with less premium and no measurable benefit to end users. Also, if you don’t have a platform that takes advantage of high PCIe/NVMe throughput, you’re essentially paying for headroom you won’t use. Bottom line: **buy it for performance-critical deployments with encryption needs**; **skip it** for anything capacity-led or lightly used.
