VK000960GWTTB is the OEM model number supplied in HPE option kit P47808-B21 for 960GB SATA 6G Read Intensive LFF LPC Multi Vendor SSD. If you have pulled a drive and read VK000960GWTTB from the label, you are looking at a 960GB TLC solid state drive on a SATA 6Gb/s interface, mounted in an HPE Low Profile carrier for 3.5-inch LFF Low Profile bays. It is a hot-swap, read intensive class drive rated at 0.8 drive writes per day and 1400 TB total endurance, with digitally signed firmware. Because HPE ships this drive under a multi vendor arrangement, the OEM model number on the label can vary between otherwise identical units.

FREQUENTLY ASKED QUESTIONS ABOUT VK000960GWTTB
What is the difference between VK000960GWTTB, P47808-B21 and P48229-001?
This page covers VK000960GWTTB, an OEM model number — the identifier the drive manufacturer puts on the physical label. P47808-B21 is the HPE option kit, the orderable number for the drive with its Low Profile carrier. P48229-001 is the HPE spare number used for replacement fulfillment. All three refer to the same physical 960GB SATA 6G read intensive drive. This family also includes one assembly revision, a manufacturing-level build identifier, and eight OEM drive models, all listed in the cross-reference block on this page.
VK000960GWTTB ships in several HPE option kits — which one do I need?
Four kits carry this drive: P05932-B21, P18424-B21, P40498-B21 and P47808-B21. All are read intensive. The difference is the carrier and the server generations each supports. P47808-B21 uses the LPC low profile carrier for Gen10 and Gen11. P40498-B21 uses the BC carrier for Gen10, Gen11 and Gen12. P05932-B21 and P18424-B21 both use the SC carrier for Gen8, Gen9 and Gen10; check the compatibility list on each kit's page to match your server.
What performance and endurance should I expect from this drive?
VK000960GWTTB delivers 58,500 IOPS on 4KB random reads and 29,000 IOPS on 4KB random writes. Internal data rates are 515 MBps read and 480 MBps write, with a 600 MBps external transfer rate over the SATA 6Gb/s link. Endurance is rated at 0.8 drive writes per day for a total of 1400 TB written, which places it in the read intensive class for workloads dominated by reads rather than sustained heavy writes.
Which servers accept this drive?
The drive fits 3.5-inch LFF Low Profile bays and ships in an HPE Low Profile carrier at 0.3 in height. Supported platforms include the DL20 Gen10 Plus, DL160 Gen10, DL180 Gen10, DL320 Gen11, DL325 Gen10 Plus, DL325 Gen10 Plus V2, DL325 Gen11, DL345 Gen10 Plus, DL345 Gen11, DL360 Gen10 Plus, DL360 Gen11, DL365 Gen10 Plus, DL365 Gen11, DL380 Gen10 Plus, DL380 Gen11, DL385 Gen10 Plus, DL385 Gen10 Plus V2, DL385 Gen11, ML30 Gen10 Plus, ML110 Gen10, ML350 Gen10 and ML350 Gen11.
What are the power and firmware characteristics?
Power draw is 1.35 W at idle, 3.02 W during random read, random write and mixed random read/write, 3.05 W on sequential read and 3.37 W on sequential write, with a 3.37 W maximum. The drive uses digitally signed firmware, so the server validates firmware authenticity before it loads. The single interface is one 7-pin Serial ATA connector running at 6 Gb/s, and the drive supports hot-swap installation.
