MB004000JWKGU is the OEM model number supplied in HPE option kit 872487-B21 for 4TB SAS 12G Midline 7.2K LFF (3.5in) SC Digitally Signed Firmware HDD. If you have pulled a drive from a chassis and read MB004000JWKGU off the label, that string identifies the drive model rather than the HPE ordering number, which is why it may not resolve directly in an HPE quote tool. The drive is a 4TB 7,200 rpm large form factor unit with a 12 Gb/s Serial Attached SCSI 3 interface, 512 bytes per sector, hot-swap operation, and an HPE Smart Carrier sized for 3.5-inch LFF bays. It belongs to the HPE Business Critical line and carries digitally signed firmware.

FREQUENTLY ASKED QUESTIONS ABOUT MB004000JWKGU
What is the difference between MB004000JWKGU, 872487-B21 and 872745-001?
They identify the same physical 4TB SAS 12G 7.2K LFF drive at different points in HPE's numbering. MB004000JWKGU, this page, is an OEM model number: the identifier the drive manufacturer prints on the label. 872487-B21 is the HPE option kit you order as new product. 872745-001 is the spare number used for service replacement. The same family also includes one assembly revision and six OEM drive models; an assembly part number tracks a specific build revision of the drive as HPE integrates it. All are listed in the cross-reference block on this page.
Which kit do I need — 833928-B21 or 872487-B21?
Both are Midline kits for this drive. 872487-B21 ships the drive in an SC carrier and covers HPE ProLiant Gen8, Gen9 and Gen10 servers, so it is the broader choice if your chassis is Gen8 or Gen9. 833928-B21 is listed for Gen10 support. If your server is Gen10, either kit may apply, so check the compatibility list on each kit's page and match it to your exact server model before ordering.
Which servers accept the drive shipped as MB004000JWKGU?
Supported ProLiant platforms include DL60 Gen9, DL80 Gen9, DL120 Gen9, DL160 Gen9, DL180 Gen9, DL320e Gen8 v2, DL360e Gen8, DL360p Gen8, DL360 Gen9, DL360 Gen10, DL380e Gen8, DL380p Gen8, DL380 Gen9, DL380 Gen10, DL388 Gen9, ML150 Gen9, ML310e Gen8 v2, ML350p Gen8, ML350 Gen9, SL4540 Gen8 and SL4545 G7. The server must provide a 3.5-inch LFF bay and a SAS controller.
Does the drive come with a carrier?
Yes. It is bundled with an HPE Smart Carrier for 3.5-inch LFF bays, so it installs as a hot-swap unit without transferring hardware from another drive. Confirm your chassis uses LFF bays, since the carrier is sized for 3.5-inch trays and will not seat in a small form factor slot.
What does digitally signed firmware mean on this drive?
The firmware image carried by this drive is digitally signed, a requirement introduced by HPE for drive firmware validation. Cross-referencing MB004000JWKGU tells you the drive is a digitally signed firmware unit rather than an earlier non-signed revision of the same 4TB SAS 12G 7.2K LFF capacity point, which matters when matching drives within an existing array.
