HP Legacy SCSI Hard Drives — Ultra320 & Ultra3

Keeping G2–G5 ProLiants and industrial systems alive since the OEMs moved on

About Legacy SCSI Drives

Somewhere in most industrial plants, labs and government facilities there is a machine that cannot be replaced — running on parallel SCSI storage that HPE stopped selling fifteen years ago. We maintain one of the largest remaining US inventories of HP Ultra320, Ultra3 and Wide Ultra SCSI drives, covering the full capacity ladder: 9.1, 18.2, 36.4, 72.8, 146 and 300 GB at 7.2K, 10K and 15K RPM.

Fitment

  • ProLiant G2–G5 hot-swap bays — DL360/DL380/ML350/ML370 era, in the classic 1-inch hot-plug tray
  • StorageWorks enclosures — MSA500/MSA1000/MSA1500 shelves and legacy EVA
  • 80-pin SCA-2 and 68-pin wide connector variants — check your backplane before ordering

Every drive is surface-tested and SMART-checked before it ships; these are working spares, not as-is pulls. When you are nursing a legacy RAID-5 set, we recommend buying a cold spare with the replacement — this stock does not get remanufactured. Email the part number on the failed drive's label (a 6-digit HP number ending in -001 or a -B22 option kit) and we will match it same day.

Frequently Asked Questions

Can you still buy SCSI hard drives in 2026?

Yes — from refurbished enterprise stock like ours. No manufacturer has produced parallel SCSI (Ultra320) drives since roughly 2010, so the remaining supply is tested surplus inventory. If your system depends on SCSI storage, buy spares now; supply only shrinks.

What is the difference between Ultra320, Ultra3 and Wide Ultra SCSI?

They are generations of the parallel SCSI bus: Wide Ultra (40 MB/s), Ultra3/Ultra160 (160 MB/s), and Ultra320 (320 MB/s). They are backward compatible — an Ultra320 drive works on an Ultra160 bus at the lower speed — as long as the connector matches (80-pin SCA hot-swap or 68-pin).

Can I replace a failed 36.4GB SCSI drive with a 72.8GB one?

In most HP Smart Array RAID sets, yes — the controller uses only 36.4GB of the larger drive to match the array. The reverse (smaller replacing larger) does not work. Match the RPM class where possible to keep rebuild times and array behavior consistent.

Do these drives work in non-HP systems?

The bare drives (Seagate Cheetah, Fujitsu, Maxtor mechanisms with HP firmware) follow the SCSI standard and work in any system with the right bus and connector. The hot-swap tray, however, is HP-specific. For Dell PowerEdge or IBM systems, see the equivalent legacy drives with their own trays.
