Western Digital WD Blue WD10EZEX 1TB internal hard drive NO.2

A 3.5" desktop HDD running 7200 RPM with 64MB cache on a SATA 6Gb/s interface. This is a tested pull, removed from working equipment, wiped, and verified on SMART before listing. WD Blue is the standard desktop line, which makes this a direct fit for OEM tower rebuilds, boot and storage drives, media libraries, external enclosures, and DVR replacements where a 1TB SATA drive is the specified part.

What ships 1x Western Digital WD10EZEX 1TB hard drive Shock-protective packaging SATA data and power cables, mounting screws, and drive rails are not included. Compatibility Any system with an open 3.5" bay and a SATA port takes this drive. That covers Dell OptiPlex, HP ProDesk and EliteDesk, Lenovo ThinkCentre and other OEM towers, custom desktop builds, external enclosures and docks, NVR and DVR security recorders, and entry-level NAS units. It works with Windows, macOS, and Linux. The drive is rated for desktop duty cycles rather than continuous 24/7 enterprise workloads. Before you buy This is a mechanical hard drive, not an SSD. Use it for capacity, archives, and secondary storage. If you want a fast boot drive, pair it with an SSD and use this for bulk files. Any single drive is a single point of failure, so keep an independent backup of anything you cannot lose. If the drive fails within the warranty window, return it for a replacement or refund. FAQ Is the WD10EZEX an SMR drive? No. It is a conventional CMR drive, so write performance stays consistent as the drive fills and it behaves correctly in a RAID array. Is this the 7200 RPM version or the 5400 RPM version? 7200 RPM. The 5400 RPM WD Blue at this capacity carries the WD10EZRZ model number. This drive is WD10EZEX. Can I use it as a boot drive? Yes. Windows, macOS, and Linux all install to it directly. An SSD boots faster, but this drive works as a full system drive. Does it need a SATA III controller? No. The drive negotiates down to SATA II and SATA I automatically. Older controllers cap throughput but the drive still works. Is the data from the previous owner still on it? No. Every drive is securely erased before listing. Is a caddy or cable included? No. The listing covers the bare drive only.
