VK001920GZCNH is the OEM model number supplied in HPE option kit P40499-B21 for 1.92TB SATA 6G Read Intensive SFF BC Multi Vendor SSD. If you pulled this string from a drive label, an iLO inventory report or a Smart Array controller listing, it identifies a 1.92TB 2.5-inch SFF hot-swap solid state drive using triple-level cell NAND on a SATA 6Gb/s interface. HPE ships this drive under a Multi Vendor designation, so the OEM model number recorded by your server depends on which manufacturer supplied that unit. All of the models under this designation carry the same capacity, interface, endurance rating and performance figures.

FREQUENTLY ASKED QUESTIONS ABOUT VK001920GZCNH
What is the difference between VK001920GZCNH, P40499-B21 and P41524-001?
They identify the same physical drive at different levels. VK001920GZCNH, the subject of this page, is an OEM model number — the manufacturer's own identifier printed on the drive and reported by system inventory tools. P40499-B21 is the HPE option kit, the orderable boxed product. P41524-001 is the spare part number used for service replacement. This family also includes one assembly revision and eight further OEM drive models, all listed in the cross-reference block on this page. An assembly part number identifies a factory build configuration of the drive.
Which kit do I need — P18426-B21 or P40499-B21?
Both are Read Intensive kits for this 1.92TB SATA drive, and the difference is the carrier and the server generations supported. P18426-B21 uses the SC carrier and covers Gen8, Gen9 and Gen10 servers. P40499-B21 uses the BC carrier and covers Gen10, Gen11 and Gen12 servers. VK001920GZCNH ships in P40499-B21 with an HPE Basic Carrier. Check the compatibility list on each kit's page against your server model before ordering.
What performance and endurance does this drive deliver?
The SATA 6Gb/s interface gives an external transfer rate of 600 MBps. Internal data rates are 520 MBps read and 470 MBps write, with 55,500 IOPS on 4KB random reads and 24,000 IOPS on 4KB random writes. Endurance is rated at 0.8 drive writes per day, or 2400 TB written over the drive's rated life, which places it in the Read Intensive drive class for workloads dominated by read activity.
Which servers accept this drive?
The BC carrier kit 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 bay and is hot-swap capable.
What are the physical and power characteristics?
The drive is a 2.5-inch small form factor unit 0.3 in high, weighing 17.64 oz with the bundled HPE Basic Carrier. Power draw is 1.35 W at idle, 3.15 W during random read, random write and mixed random read/write operations, 3.16 W on sequential read and 3.53 W on sequential write, which is also the maximum. Firmware is digitally signed, and the drive connects through a single 7-pin Serial ATA port.
