Is this drive good for gaming?

It holds a large game library and installs over standard SATA, but games load slower than from an SSD. Use it for storage and keep actively played games on an SSD.

Does it fit a laptop?

No. It is a 3.5-inch desktop drive, so it needs a desktop bay or an external enclosure.

What is the cache size?

256MB, paired with a 7200 RPM spindle and a SATA interface.

How long is the warranty?

Western Digital covers it with a five-year limited warranty.

Can I use it in a NAS?

It is a desktop gaming drive, not a NAS-rated model. For always-on multi-drive use, pick a drive rated for that workload.

What comes in the box?

The drive itself. SATA cables and mounting screws are not included, so check your case and motherboard for those.

Our take on the Western Digital WD_BLACK WD6004FZBX internal hard drive

The WD_BLACK WD6004FZBX is a 6TB 3.5-inch desktop hard drive spinning at 7200 RPM with a 256MB cache and a SATA interface. It is built for game libraries and large media collections, and Western Digital backs it with a five-year limited warranty. Against 5400 RPM bulk drives it moves large files faster, but it is a mechanical drive: a SATA SSD boots games and loads levels quicker. Buyers pick it for capacity per drive and for the long warranty rather than for speed.

What reviewers say

Owners treat this drive as bulk game and media storage: they like the capacity and the five-year warranty, and accept that it is a hard drive rather than an SSD. The recurring complaints are noise and the fact that it does not speed up game loading the way an SSD does.

What people mention

CapacityPraisedOwners like fitting a whole game library on one drive.
NoiseCriticisedThe 7200 RPM mechanism is audible during seeks and sustained writes.
SpeedMixedFast for a hard drive on large files, but far behind SSDs for game loading.
WarrantyPraisedThe five-year limited warranty is seen as reassurance for a storage drive.
BuildMixedSome owners report vibration that needs secure mounting in the case.
