Our take on the Seagate BarraCuda ST328040A 28GB 7200RPM IDE Ultra ATA/66 512KB Cache 3.5-inch Hard Drive

The Seagate BarraCuda ST328040A is a 28GB 3.5-inch desktop hard drive with a 7200RPM spindle, 512KB cache and an IDE Ultra ATA/66 interface. It is a period part for keeping old PCs, retro builds and legacy workstations running, not a drive for a modern machine. Against today's SATA and NVMe drives it is tiny, slow and obsolete, and its value is compatibility with old IDE controllers and motherboards. Buyers of these drives want a working replacement for a failed original, not capacity or speed.

Questions and answers

Will this drive work in a modern PC?
No. It uses a 40-pin IDE Ultra ATA/66 interface, which current motherboards do not have. You would need an old IDE controller or a bridge adapter.
Is 28GB enough for Windows?
It can hold an older Windows install and basic files, but not a modern OS with updates and applications. Treat it as a period-correct drive for retro use.
What cable and power does it need?
A standard 40-pin IDE ribbon cable and a Molex power connector. It is a 3.5-inch desktop drive, so it mounts in a standard bay.
How does it compare with a SATA drive?
A SATA drive is far faster, larger and easier to connect. This drive only makes sense when the machine has no SATA ports.
Can I use it as an external drive?
Yes, with a USB-to-IDE enclosure that supports 3.5-inch drives and provides external power. Check the adapter lists Ultra ATA/66 support.
