Our take on the Seagate ST4000DX000 BarraCuda XT 4TB 7200RPM SATA 6Gb/s 64MB Cache 3.5-inch Hard Drive

The Seagate BarraCuda XT 4TB (ST4000DX000) is a 3.5-inch internal desktop hard drive spinning at 7200 RPM with a SATA 6Gb/s interface and 64MB cache. It is a mechanical drive built for bulk storage in a desktop tower or NAS-style enclosure, not for a laptop. Against 5400 RPM drives of the same capacity it moves large files faster, but it is louder and hotter, and against SSDs it is far slower for random access. It suits buyers who need a lot of room for media, backups or archives and have a spare 3.5-inch bay.

Questions and answers

Is this drive good for a desktop PC?
Yes. It is a 3.5-inch internal SATA drive, so it fits a standard desktop bay and works as a main or secondary data drive. It is not a laptop drive.
Should I use it as my Windows or game drive?
It works, but an SSD will boot and load games far faster. Use this drive for storage and keep the operating system and games on an SSD.
How fast is it compared with an SSD?
Sequential transfers are respectable for a hard drive, but random reads and writes are many times slower than an SSD. Expect seconds, not fractions of a second, for small-file work.
Does it need extra power or cables?
It uses a standard SATA data cable and a SATA power connector from the power supply. Both are typical in desktop builds.
Can I put it in a NAS or external enclosure?
It is a plain SATA drive, so it works in an enclosure or a small NAS. Check that the enclosure takes 3.5-inch drives and provides cooling.
Is 4TB enough for a media library?
It holds a large photo or music collection and a good number of HD films. Video editors and large game libraries will fill it quickly.
