300 GB Ultra320 SCSI Drive

This IBM 40K1025 is a 300 GB internal hard drive with a 3.5 inch form factor. It spins at 10000 rpm and connects through an Ultra320 SCSI interface. The unit includes an 8 MB buffer and supports hot-swappable operation. It is supplied in refurbished condition.

Suits legacy SCSI systems

This drive fits PCs that require a 3.5 inch Ultra320 SCSI drive with hot-swap capability. It is not for buyers who need larger capacities, faster spindle speeds, or modern interface standards. Systems without a compatible Ultra320 SCSI controller cannot use this drive.

Ultra320 SCSI interface decides fit

The single specification that determines compatibility is the Ultra320 SCSI interface standard. Your system must provide a matching Ultra320 SCSI connection and support 3.5 inch hot-swappable drives for this unit to work.

Questions about this item

What maintenance will the 3.5" 10000 rpm mechanism need later?

Mechanical drives at 10000 rpm eventually require bearing or motor service; plan for replacement when error rates rise or SMART attributes degrade.

What limit appears first under sustained use on the Ultra320 SCSI interface?

The 320 MB/s bus ceiling is reached before the 8 MB buffer can absorb continuous write streams, capping sustained throughput.

How much noise, heat or power does the 300 GB drive produce running all day?

A 3.5" 10000 rpm SCSI drive generates noticeable whine and heat under constant load; ensure adequate chassis airflow and a robust power supply.
