FREQUENTLY ASKED QUESTIONS ABOUT VK001920GXWBQ
What is the difference between VK001920GXWBQ, P40499-B21 and P41524-001?
All three identify the same physical 1.92TB SATA 6G read intensive SSD. VK001920GXWBQ, this page, is an OEM model number: the identifier the drive manufacturer prints on the label, which is what you see when you pull the drive. P40499-B21 is the HPE option kit you order, which includes the drive in an HPE Basic Carrier. P41524-001 is the spare part number. This family also includes one assembly revision and eight OEM drive models, all listed in the cross-reference block on this page. An assembly part number identifies the drive-plus-carrier build as HPE assembles it.
Which kit do I need — P18426-B21 or P40499-B21?
Both are Read Intensive kits built around the same 1.92TB SATA 6Gb/s drive, and the difference is the carrier and the server generations it fits. P18426-B21 ships with an SC carrier and covers Gen8, Gen9 and Gen10 servers. P40499-B21 ships with the HPE Basic Carrier (BC) and covers Gen10, Gen11 and Gen12 servers. Match the carrier type to your chassis drive bays, then confirm your exact model against the compatibility list on the kit page.
Which servers accept this drive?
The BC-carrier configuration 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 bay must be a 2.5-inch SFF SATA bay.
What workloads is this drive rated for?
It is a read intensive class drive at 0.8 drive writes per day with 2400 TB of rated endurance, so it suits read-heavy workloads such as boot volumes, content serving, virtual desktop images and analytics reads. Random performance is 55,500 IOPS at 4KB read against 24,000 IOPS at 4KB write, reflecting that read bias. Sustained write-intensive logging or database journaling is better served by a higher DWPD class.
What are the physical and power characteristics?
The drive is a 2.5-inch SFF hot-swap unit, 0.3 in high, weighing 17.64 oz with the bundled HPE Basic Carrier. Power draw is 1.35 W idle, 3.15 W during random read, random write and mixed random read/write, 3.16 W for sequential read and 3.53 W for sequential write, with a maximum of 3.53 W. External transfer rate is 600 MBps over the SATA 6Gb/s interface.
