FREQUENTLY ASKED QUESTIONS ABOUT VK000960GWTTB
What is the difference between VK000960GWTTB, P18424-B21 and P18483-001?
This page, VK000960GWTTB, is an OEM model number: the code the drive manufacturer puts on the label, which is what you see in inventory tools. P18424-B21 is the HPE option kit, the orderable boxed configuration. P18483-001 is the spare part number used for replacement fulfillment. All three refer to the same physical 960 GB SATA 6G Read Intensive SFF drive. The family also includes one assembly revision and nine other OEM drive models, all listed in the cross-reference block on this page. An assembly part number identifies a specific build revision of the drive and carrier.
VK000960GWTTB ships in several HPE option kits — which one do I need?
This drive ships under P05932-B21, P18424-B21, P40498-B21 and P47808-B21, all Read Intensive. The difference is the carrier and the server generations it fits. P05932-B21 and P18424-B21 use the SC carrier and cover Gen8, Gen9 and Gen10. P40498-B21 uses the BC carrier for Gen10, Gen11 and Gen12. P47808-B21 uses the LPC carrier for Gen10 and Gen11. Match the carrier to your chassis bays, then confirm against the compatibility list on each kit's page.
Will a drive labeled VK000960GWTTB work in my server?
In SC carrier form this drive is supported across a wide range of HPE platforms, including ProLiant DL and ML Gen8, Gen9 and Gen10 rack and tower servers, DL325 Gen10 Plus v1 and DL385 Gen10 Plus v1, BL and WS blades from Gen8 through Gen10, SL and Apollo XL nodes, and Synergy 480 and 660 compute modules in Gen9 and Gen10. The bay must be 2.5-inch SFF with a SATA 6 Gb/s connection.
What does Read Intensive mean on this drive?
Read Intensive is the HPE drive class designation for this 960 GB SSD. It describes the endurance tier HPE assigns to the drive, positioning it for workloads dominated by read operations rather than sustained heavy writes. All four option kits that carry this drive are Read Intensive, so the class does not change between kits. The interface remains a single SATA 6 Gb/s port with a 600 MBps external transfer rate.
Does VK000960GWTTB include a drive carrier?
Yes. As supplied in option kit P18424-B21, the drive is bundled with the HPE Smart Carrier (SC) and fits a 2.5-inch SFF hot-swap bay. The SC carrier is the tray used on Gen8, Gen9 and Gen10 platforms. Other option kits containing this same drive use the BC or LPC carrier instead, so verify which tray style your chassis bays accept before ordering a replacement.
