FREQUENTLY ASKED QUESTIONS ABOUT MB004000JWWQB
What is the difference between MB004000JWWQB, 872487-B21 and 872745-001?
They identify the same physical drive at different points in HPE's numbering system. MB004000JWWQB, this page, is an OEM model number: the identifier printed on the drive itself by the manufacturer that built it. 872487-B21 is the HPE option kit number used for ordering the drive as a boxed product. 872745-001 is the HPE spare number used for replacement fulfilment. This family also includes one assembly revision and six OEM drive models, all listed in the cross-reference block on this page. An assembly part number tracks a specific build revision of the finished unit.
Which kit do I need — 833928-B21 or 872487-B21?
Both are Midline kits containing this 4TB 7.2K LFF SAS drive. 872487-B21 ships the drive in an SC carrier and covers Gen8, Gen9 and Gen10 servers, so it is the broader choice if your chassis is older than Gen10. 833928-B21 is listed as supporting Gen10. Check the compatibility list on each kit's page against your exact server model and generation before ordering, since carrier and backplane requirements vary by chassis.
Which servers accept a drive with model number MB004000JWWQB?
This drive is compatible with the ProLiant DL60, DL80, DL120, DL160, DL180, DL360, DL380 and DL388 Gen9 servers, DL360 and DL380 Gen10, DL320e Gen8 v2, DL360e, DL360p, DL380e and DL380p Gen8, ML150 Gen9, ML310e Gen8 v2, ML350p Gen8, ML350 Gen9, SL4540 Gen8 and SL4545 G7. The server must provide a 3.5-inch LFF bay for the Smart Carrier to seat correctly.
What are the performance specifications of this drive?
MB004000JWWQB is a 4TB midline hard drive spinning at 7,200 rpm with a single SAS 12 Gb/s interface port and a 12 Gb/s data transfer rate. It uses Serial Attached SCSI 3 as both the drive and storage interface and is formatted at 512 bytes per sector. It is a hot-swap unit, so it can be removed and replaced while the server is running, subject to the array configuration.
Does this drive include a carrier?
Yes. The drive is bundled with an HPE Smart Carrier sized for 3.5-inch LFF bays (8.9 cm). The carrier lets the drive seat directly into a supported ProLiant hot-swap backplane without a separate tray purchase. Drives with digitally signed firmware are validated by HPE Smart Array controllers during firmware updates, which confirms the firmware image originated from HPE before it is applied.
