FREQUENTLY ASKED QUESTIONS ABOUT VK001920GXNZC
What is the difference between VK001920GXNZC, P40499-B21 and P41524-001?
VK001920GXNZC, this page, is an OEM drive model number — the identifier printed on the drive itself by the manufacturer that built it. P40499-B21 is the HPE option kit part number you order to receive the drive with its Basic Carrier. P41524-001 is the spare part number used for service replacement. All three refer to the same physical 1.92TB SATA 6G Read Intensive SFF SSD. 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 manufactured.
Which kit do I need — P18426-B21 or P40499-B21?
Both are Read Intensive kits, and the difference is the carrier and the servers it fits. P18426-B21 ships on an SC carrier and supports Gen8, Gen9 and Gen10 servers. P40499-B21 ships on a BC (Basic Carrier) and supports Gen10, Gen11 and Gen12 servers. This page covers the drive as supplied in P40499-B21. If your platform is Gen10, check the compatibility list on each kit's page to confirm which carrier your chassis bays accept.
Which servers accept this drive?
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. The bay must be 2.5-inch SFF.
What endurance and power figures apply to VK001920GXNZC?
This is a Read Intensive class drive rated at 0.8 drive writes per day with 2,400 TB total endurance, using triple-level cell NAND. Power draw is 1.35 W at idle, 3.15 W during random read, random write and mixed random read/write, 3.16 W on sequential read, and 3.53 W on sequential write, which is also the maximum. The drive is 0.3 in high and weighs 17.64 oz with carrier.
What interface speed does this drive run at?
VK001920GXNZC uses a single SATA 6 Gb/s connection over a 7-pin Serial ATA interface, giving an external transfer rate of 600 MBps. Internal data rates are 520 MBps read and 470 MBps write. It is a hot-swap drive, so it can be installed or removed while the server is running, provided the controller and array configuration support that operation.
