HPE 781516-B21 is the option kit for a 600GB Enterprise hard drive in the SmartDrive Carrier. The drive is 2.5 inch small form factor, runs at 10,000 rpm and connects through a 12Gb/s SAS interface. It was a standard drive option across HPE ProLiant Gen9 and Gen10 servers and also fits Gen8 SFF SmartDrive bays.
This is a dependable choice for organisations that need reasonable capacity with Enterprise-grade performance. Typical uses include virtual machine datastores for small clusters, application servers, line-of-business databases and RAID 10 sets for mixed workloads. It is also widely used as a like-for-like replacement in servers that shipped with 600GB 10K drives.

The -B21 ending marks an HPE option kit, the form in which a part is sold for upgrades and new configurations. HPE service supplies the same 600GB 10K drive as spare part 781577-001, and an Australian HPE parts distributor lists 781516-B21 as the option equivalent of that spare. Drive model numbers reported under this kit include EG0600JEHMA, EG0600JEMCV, EG0600JETKA and EG000600JWEBH.
Several assembly numbers also point to it, such as 768788-002 and 781514-001. If you hold a drive with any of these numbers, 781516-B21 is the matching option kit. Ordering against the exact number protects you from mixing in a 15K drive or an older 6G model by mistake.
Gen9 and Gen10 Smart Array controllers support 12Gb/s SAS, so this drive links at full speed there. In a Gen8 server, the controller tops out at 6Gb/s, and the drive simply runs at that rate. A single 10K disk does not saturate either link, so the practical difference is small for one drive. It matters more in fully populated chassis where many drives share the controller.
The drive can therefore be used to replace a failed 6G 600GB 10K drive in a Gen8 server, although it is best practice to keep the drives within one array as alike as possible.
A New 781516-B21 is suited to filling bays in a server you have just bought, building a new array from scratch or keeping a sealed spare. The product page carries the condition and warranty details for New units.
Choosing Refurbished can make sense when you need to replace a failed drive in a server that still has years of useful life. It keeps costs predictable for maintenance budgets. Condition and warranty for Refurbished units are on the product page.
Lists of this kind are compiled from parts data and may miss some systems. Check your server model, controller and existing drive label before you order.
The assembly number HPE 768788-002 is linked to this option kit. Listings for HPE 787677-002 and HPE EG000600JWJNP cover other 600GB 10K 2.5 inch drives in our catalogue.
Replacing 300GB drives with 600GB drives can double usable space without changing servers. With Smart Array, you can swap drives one at a time, waiting for each rebuild, then expand the array and logical drive once all members are larger. It takes patience, so take a full backup first and schedule the work over several quiet periods.

Yes, it is listed for Gen8 SFF SmartDrive bays as well as Gen9 and Gen10, and in Gen8 servers it runs at the 6Gb/s speed of the controller.
The spare part number for the 781516-B21 option kit is 781577-001, and both refer to the 600GB 12G SAS 10K SFF SC Enterprise drive.
