WD_BLACK 10TB Performance Hard Drive (WD102FZBX): specs and who it suits

The WD_BLACK 10TB Performance drive (WD102FZBX) is a 3.5-inch internal hard drive for desktop PCs. Western Digital designs the WD_BLACK line for gamers, system builders and creative professionals who need a lot of storage for large game libraries, project files and archives. Here is what its specifications mean in practice.

Why capacity is the main point

Ten terabytes is room for a large collection of modern games, many of which take tens or even hundreds of gigabytes each, plus video footage, photo libraries and backups. Western Digital's description pitches it as a way to keep a big catalogue of current and older titles ready to play instead of constantly uninstalling.

As the brand notes, drive makers count 1TB as one trillion bytes, so the capacity your operating system reports will be somewhat lower. That is normal for every drive.

7200 RPM and the 512 MB cache

The platters spin at 7200 revolutions per minute. Faster rotation generally means the head reaches data sooner and sustained transfer is higher than with 5400 RPM drives, which is why 7200 RPM is common in performance desktop drives. The 512 MB cache is a buffer of fast memory on the drive that smooths short bursts of reads and writes.

It is still a mechanical drive. Compared with an SSD, a hard drive typically starts programs and loads game levels more slowly, and handles many small random reads less quickly. Many builders use an SSD for the operating system and most-played games and a hard drive like this for bulk storage.

StableTrac and Dynamic Cache

Western Digital says its StableTrac technology and Dynamic Cache technology increase reliability and optimise performance. As the brand describes it, StableTrac secures the motor shaft at both ends to reduce vibration, and Dynamic Cache adjusts how the cache is allocated according to the workload. Treat these as the brand's own descriptions of its design.

SATA 6 Gb/s connection

The drive uses the SATA III interface at 6 Gb/s, which almost every desktop motherboard supports and which is backward compatible with older SATA ports. A single hard drive does not fill that link, so the interface will not limit it. You need a SATA data cable and a SATA power connector from the power supply.

Size and fit

It is a standard 3.5-inch drive, around 7.6 x 5.0 x 2.5 inches and about 1.5 lb. It suits desktop cases with 3.5-inch bays, or a 2.5-inch bay with a bracket adapter, and is not designed for most laptops. Hard drives also make some noise while seeking, and spin up a little slower than solid-state storage.

Who it suits

It suits desktop owners who need a large amount of storage for games, media or work files, and builders adding a second drive to a system with an SSD. It is less suited to someone who wants the quickest possible load times from a single drive, or to laptop users.

What to check before you buy

• Bay space: confirm your case has a free 3.5-inch bay or an adapter for another size.
• Ports and cables: make sure a free SATA port, data cable and power lead are available.
• Backups: one drive is one copy; keep important files backed up elsewhere.
• Noise and vibration: check the case mounting and consider rubber grommets if noise matters.
• Usable space: expect the reported capacity to be lower than 10TB.

The short version

• A 10TB, 3.5-inch internal desktop hard drive, model WD102FZBX.
• 7200 RPM, 512 MB cache, SATA 6 Gb/s.
• Western Digital cites StableTrac and Dynamic Cache technology.
• Best understood as bulk storage next to an SSD, for gamers, builders and creators.
