Our take on the Seagate Barracuda ST3300631A 300 GB 3.5 Internal Hard Drive

The Seagate Barracuda ST3300631A is a 300 GB desktop hard drive on the older IDE Ultra ATA/100 interface, spinning at 7200 rpm with a 16 MB buffer. It is a period part for reviving or repairing a pre-SATA PC, not a drive for a modern build. Its 7200 rpm spindle and 16 MB cache were solid mid-range figures for its generation, but today's SATA and NVMe drives are far faster and far larger. Buy it only if your motherboard has an IDE header and you need a working drive for an old machine.

Pros
  • 300 GB capacity is generous for an IDE-era system
  • 7200 rpm spindle and 16 MB buffer for its class
  • Standard 3.5-inch desktop form factor
  • Seagate Barracuda line is well known among legacy PC builders
Cons
  • IDE Ultra ATA/100 interface will not connect to modern SATA ports
  • Mechanical drive with moving parts, so used units carry failure risk
  • Far slower and smaller than any current SATA or NVMe drive
  • No modern features such as SATA, NCQ or SMART over current tools

Questions and answers

Will this drive work in a modern PC?
No. It uses the IDE Ultra ATA/100 ribbon-cable interface, which current motherboards do not have. You need an older board with an IDE header, or an IDE-to-SATA/USB adapter.
How fast is it compared with an SSD?
Much slower. A 7200 rpm mechanical drive with a 16 MB buffer is measured in tens of megabytes per second, while SATA SSDs and NVMe drives are several times faster.
What is the difference between ST3300631A and ST3300631A-RK?
The -RK suffix marks the retail kit version of the same 300 GB Barracuda drive. The core specifications, 7200 rpm and 16 MB buffer, are the same.
Is 300 GB enough for an old PC?
For a Windows XP-era machine used for documents, photos and light software, yes. It is small by current standards, so plan on an external drive for large media libraries.
Can I use it in an external enclosure?
Yes, with an IDE-to-USB enclosure or adapter. The drive is a standard 3.5-inch unit, so it needs a powered enclosure.
Where is the Seagate Barracuda ST3300631A 300 GB 3.5 Internal Hard Drive cheapest?
At Tech Network Supply LLC, for $443.80, as of our latest check.
