FREQUENTLY ASKED QUESTIONS ABOUT VK001920GXAWN
What is the difference between VK001920GXAWN, P40499-B21 and P41524-001?
This page, VK001920GXAWN, 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 part number, the orderable kit that includes the drive on its carrier. P41524-001 is the spare part number used for service replacement. 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 revision, and OEM model numbers vary by the vendor that produced the drive. All are listed in the cross-reference block on this page.
VK001920GXAWN ships in several HPE option kits — which one do I need?
This drive ships under P18426-B21, P19941-B21 and P40499-B21. All three are Read Intensive kits. P40499-B21 uses the BC (Basic Carrier) and covers Gen10, Gen11 and Gen12 servers. P18426-B21 and P19941-B21 both use the SC carrier and cover Gen8, Gen9 and Gen10 servers. Match the carrier to your chassis bays first, then confirm your exact server model against the compatibility list on each kit's page before ordering.
Which servers accept this drive on the BC carrier?
The BC-carrier configuration is listed for 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. It occupies a 2.5-inch SFF hot-swap bay.
What are the performance and endurance figures for VK001920GXAWN?
The interface runs at 6 Gb/s with an external transfer rate of 600 MBps. Internal data rates are 520 MBps read and 470 MBps write. Random performance is 55,500 IOPS at 4KB read and 24,000 IOPS at 4KB write. Endurance is 0.8 drive writes per day for a total of 2400 TB written, which places it in the Read Intensive drive class rather than mixed use or write intensive.
What are the physical and power characteristics?
The drive is a 2.5-inch SFF unit 0.3 in high, weighing 17.64 oz including the bundled HPE Basic Carrier, and connects through a single 7-pin Serial ATA port. Idle draw is 1.35 W. Random read, random write and mixed random read/write all draw 3.15 W, sequential read 3.16 W, and sequential write 3.53 W, which is also the maximum figure. NAND is triple-level cell (TLC).
