FREQUENTLY ASKED QUESTIONS ABOUT VK001920GWTTC
What is the difference between VK001920GWTTC, P40499-B21 and P41524-001?
VK001920GWTTC, this page, is an OEM model number — the identifier the drive manufacturer assigns and the string that appears on the drive label and in controller inventory output. P40499-B21 is the HPE option kit, the orderable box that includes the drive on its carrier. P41524-001 is the spare part number used for replacement units. All three refer to the same physical drive. This family also includes one assembly revision and eight OEM drive models; an assembly number identifies a factory build configuration of the same drive, and the full cross-reference block on this page lists them.
VK001920GWTTC ships in several HPE option kits — which one do I need?
This drive ships under P05938-B21, P18426-B21 and P40499-B21. All three are Read Intensive kits. P40499-B21 uses the BC (Basic Carrier) and covers Gen10, Gen11 and Gen12 servers. P05938-B21 and P18426-B21 both use the SC carrier and cover Gen8, Gen9 and Gen10 servers; check the compatibility list on each of those two kit pages to match your specific server model. Match the carrier type to your chassis drive bays first, then confirm the generation coverage.
Which servers accept this drive?
With the BC carrier from kit P40499-B21, the drive fits 2.5-inch SFF bays in ML30 Gen10 Plus, DL20 Gen10 Plus, DL325 Gen10 Plus v2, DL345 Gen10 Plus, DL360 Gen10 Plus, DL365 Gen10 Plus, DL380 Gen10 Plus and DL385 Gen10 Plus v2; ML30, ML110, ML350, DL20, DL320, DL325, DL345, DL360, DL365, DL380, DL385 and DL560 Gen11; and ML350, DL320, DL340, DL345, DL360, DL380 and DL580 Gen12.
What endurance and performance should I expect from this drive?
It is classed Read Intensive at 0.8 drive writes per day, with 2400 TB of total write endurance across its life. Sequential rates are 520 MBps read and 470 MBps write, against a 600 MBps external transfer rate on the SATA 6Gb/s link. Random performance is 55,500 IOPS on 4KB reads and 24,000 IOPS on 4KB writes. The NAND is triple-level cell. This profile suits read-heavy workloads such as boot volumes, content serving and analytics reads.
What are the physical and power characteristics?
The drive is a 2.5-inch small form factor hot-swap unit, 0.3 inches high, weighing 17.64 oz with the HPE Basic Carrier it is bundled with. It connects through a single 7-pin Serial ATA port at 6 Gb/s. Idle draw is 1.35 W, rising to 3.15 W for random read, random write and mixed random read/write, 3.16 W for sequential read and 3.53 W for sequential write, which is also the maximum.
