HPE P18422-B21 480GB SATA 6G SFF Read Intensive SSD SC Multi Vendor

The HPE P18422-B21 is a 480GB, 2.5-inch SFF SATA SSD supplied in an HPE Smart Carrier (SC), the hot-plug tray with status LEDs used across ProLiant Gen10 servers. It is a Multi Vendor SKU, so the internal drive may come from any maker HPE has qualified for this part number. HPE PartSurfer maps it to spare part P18482-001. Do not confuse it with the P40497-B21: both are 480GB SATA Read Intensive drives, but the P40497-B21 ships in a Basic Carrier for Gen10 Plus and Gen11, while the P18422-B21 uses the Smart Carrier for Gen10.

At 480GB and a Read Intensive rating, this drive is mostly bought as a boot or OS drive, usually as a mirrored pair, or for light read-heavy roles such as hypervisor installs, management VMs, small web servers and appliance software. It is also a common like-for-like replacement for failed drives in existing Gen10 fleets, where keeping the same carrier and part number keeps the array and support records simple.

HPE's DL380 Gen10 and DL560 Gen10 QuickSpecs list this part among their SFF SATA Read Intensive options. Resellers also describe Smart Carrier SATA drives as working in older Gen8 and Gen9 servers, but HPE's documents for those generations were not checked here, so confirm with the QuickSpecs for your exact model. The drive runs at 6Gb/s SATA and works with HPE Smart Array controllers or a SATA-capable onboard controller through a SAS/SATA backplane.

• Confirm your bays take Smart Carrier (SC) drives; Gen10 Plus and Gen11 servers use Basic Carrier and need P40497-B21 instead.
• Check that your controller supports SATA drives in the target bay.
• For RAID replacement, match capacity and interface to the failed drive.
