WD Black 10TB Desktop Hard Drive

The WD Black WD101FZBX is a 10TB 3.5 inch internal hard drive built for desktop PCs. It uses a SATA 6.0Gb/s interface and spins at 7200 RPM with 256MB of DRAM cache. The CMR recording technology supports sustained performance for creative professionals, gamers and system builders who need large capacity storage.

Standard 3.5 Inch SATA Installation

Installation follows the standard 3.5 inch drive bay pattern using SATA data and power cables. The drive measures 147.00mm long, 101.60mm wide and 26.10mm high. Ensure the case bay and cable routing accommodate these dimensions. A common issue is forgetting to connect both the SATA data cable to the motherboard and the SATA power cable from the power supply.

10TB CMR Capacity Decides Suitability

The single specification that determines fit is the 10TB CMR capacity combined with 7200 RPM speed and 256MB cache. This configuration targets users who need high-capacity mechanical storage for large game libraries or media files. Buyers who want faster boot times or silent operation should consider solid-state alternatives instead.

Questions about this item

How can I confirm the drive is running at 7200 RPM with 256MB cache after installation?

Use a tool such as CrystalDiskInfo to verify the rotational speed shows 7200 RPM and the buffer size reads 256 MB; the SATA 6.0Gb/s link rate should also be reported.

What is included in the box and what must be purchased separately for this 3.5" SATA drive?

The retail or OEM package contains the 10TB drive only; you will need to supply a SATA data cable, a SATA power connector from your PSU, and a 3.5" drive bay or mounting bracket.

Which capacity version should I choose if I want the 256MB DRAM cache and 10TB storage?

The WD101FZBX model provides the full 10TB capacity with 256MB cache; lower-capacity models in the same series may have smaller cache sizes.
