FREQUENTLY ASKED QUESTIONS ABOUT VK001920GWTHC
What is the difference between VK001920GWTHC, P40499-B21 and P41524-001?
All three identify the same physical 1.92TB SATA 6G Read Intensive SFF SSD. VK001920GWTHC, this page, is an OEM model number: the identifier printed on the drive itself by the manufacturer that built it. P40499-B21 is the HPE option kit number you order. P41524-001 is the spare number used for replacement fulfilment. This family also includes one assembly revision and eight OEM drive models; an assembly number identifies the drive as built and tested for HPE. All are listed in the cross-reference block on this page.
VK001920GWTHC ships in several HPE option kits — which one do I need?
This drive ships under P06198-B21, P18426-B21 and P40499-B21, all Read Intensive. P40499-B21 uses the BC (Basic Carrier) and covers Gen10, Gen11 and Gen12 servers, which is the kit matching this page. P06198-B21 and P18426-B21 both use the SC carrier and cover Gen8, Gen9 and Gen10 servers; to choose between those two, check the compatibility list on each kit's page against your exact server model and generation.
What are the performance and endurance figures for this drive?
The drive delivers 55,500 IOPS on 4KB random reads and 24,000 IOPS on 4KB random writes. Internal data rates are 520 MBps read and 470 MBps write, with a 600 MBps external transfer rate over the SATA 6Gb/s interface. Endurance is rated at 2400 TB written, or 0.8 drive writes per day, which places it in the Read Intensive drive class for workloads weighted toward reads rather than sustained heavy writes.
Which servers accept this drive?
It fits 2.5" SFF hot-swap bays and is supported 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. The HPE Basic Carrier is included.
What power does the drive draw?
Idle draw is 1.35 W. Random read, random write and mixed random read/write operations each draw 3.15 W. Sequential reads draw 3.16 W and sequential writes 3.53 W, which is also the maximum figure. The drive is 0.3 in high and weighs 17.64 oz with its carrier. Firmware is digitally signed, so the drive validates authenticated firmware images before they are applied.
