Our take on the Seagate Barracuda 400 GB 3.5 Internal Hard Drive - Retail - SATA/300 - 7200 rpm - 16 MB Buffer

The Seagate Barracuda ST3400633AS-RK is a 3.5-inch desktop hard drive with 400 GB of capacity, a 7200 rpm spindle and a 16 MB buffer over a SATA/300 interface. It is a retail-boxed drive from the era when 400 GB was a mid-size desktop disk, so it suits older PCs, spare-part builds and bulk storage of files rather than a modern system drive. Against today's large-capacity drives it offers a fraction of the space and slower sequential transfers, and its age means used or new-old-stock units carry real reliability risk. Buy it for a legacy machine that needs a period-correct SATA disk, not for a new build.

Questions and answers

Is this drive good for a modern PC build?
No. Its 400 GB capacity and older SATA/300 interface make it a poor choice for a new system. Use it for a legacy machine or secondary storage.
Will it work in a laptop?
No. It is a 3.5-inch desktop drive, which is too large for a laptop bay. It needs a desktop case or an external enclosure with its own power.
What interface does it use?
It uses SATA/300, which connects to standard SATA ports on desktop motherboards. It will run at the slower of the drive and port speeds.
How much can it hold?
It holds 400 GB. That is roughly 80,000 photos or a few hundred hours of compressed video, far less than current drives.
Does it come with cables?
It is a retail-boxed drive, but the listing does not specify included cables. Check the box contents before relying on it for a build.
