641552-001 is the HPE assembly part number supplied in HPE option kit 507127-B21 for 300GB 2.5" SFF 6G Dual Port SAS 10K RPM Hot Plug Hard Drive. If you are reading this number off a drive label or a PartSurfer result, it identifies a 300GB 10,000 rpm SAS hard drive with a 6 Gb/s dual port interface in a 2.5-inch low profile form factor, measuring 0.591" high and 2.75" wide. The drive is a hot-plug server and storage unit device and ships with its hot-swap tray attached. Assembly numbers like this one appear on the physical product rather than on the orderable kit, so the number printed on your drive will often differ from the number you order under.

FREQUENTLY ASKED QUESTIONS ABOUT 641552-001
What is the difference between 641552-001, 507127-B21 and 507284-001?
All three identify the same physical drive. This page, 641552-001, is an assembly part number — the number HPE prints on the built drive assembly itself, which is what you typically see on the label or in PartSurfer. 507127-B21 is the orderable option kit number. 507284-001 is the spare part number used for service replacement. This family also includes ten further assembly revisions, 16 OEM drive models, two generic part numbers and one alternate part number, all listed in the cross-reference block on this page.
641552-001 ships in several HPE option kits — which one do I need?
This drive ships under option kits 507127-B21, 652564-B21 and AP875A. 652564-B21 is an Enterprise product line kit using an SC carrier and covering Gen8, Gen9 and Gen10 servers, so choose it if your server is one of those generations. 507127-B21 and AP875A cover other platforms; check the compatibility list on each kit's page against your specific server model before ordering, since the drive inside is identical in every case.
I have a drive labelled with an OEM model number, not 641552-001. Is it the same part?
Likely yes. An OEM model number is the drive manufacturer's own product code, printed on the label alongside HPE's numbers. This product family has 16 such OEM models, all corresponding to the same 300GB 6 Gb/s dual port SAS 10K rpm 2.5-inch hot-plug drive. Compare the model number on your label against the cross-reference block on this page to confirm it belongs to this family.
Which servers accept this drive?
It is supported in a broad range of HPE ProLiant, BladeSystem and Integrity platforms, including BL460c G1/G5/G6/G7, BL465c G1/G5/G6/G7, BL685c G1/G5/G6/G7, BL860c and BL870c, DL360 G4p through G7, DL380 G4 through G7, DL385 G1 through G7, DL580 G3/G4/G5/G7, DL585 G1 through G7, DL785 G5/G6, DL980 G7, ML350 G5/G6, ML370 G4/G5/G6, ML570 G3/G4, SL390s G7 and WS460c G6, among others listed on this page.
Does 641552-001 include a caddy?
Yes. The hot-swap tray is included and attached to the drive. The assembly is a 2.5-inch low profile SFF unit measuring 0.591" in height and 2.75" in width, configured as a hot-plug device for server and storage unit bays. No separate carrier purchase is needed for the bays this form factor and tray are designed for.
