Description
HP P18422-B21 480GB SATA 2.5" SSD
The P18422-B21 is HPĀs 480GB SATA drive in the 2.5-inch SFF size, running at 6Gb/s with a Read Intensive endurance rating and coded for ProLiant servers. Not every machine needs to be all flash. Plenty of servers run a mix, with a handful of SSDs carrying the data people actually touch and spinning disks underneath holding everything else. ItĀs internal, RoHS and WEEE compliant.

Performance and Applications
Hybrid arrangements work because data never gets used evenly. A small share of it gets read constantly while the rest sits untouched for months at a stretch. Put that busy portion on a pair of 480GB SSDs, leave the archive on cheaper high-capacity disks, and the server feels quick exactly where people notice without the bill an all-flash chassis brings. Read Intensive suits the flash tier precisely, since that tier serves out far more than it takes in. Database indexes, operating system volumes, and busy shared folders all belong there.
Compatibility and Installation
YouĀll need a free 2.5-inch SFF bay, a SATA connection, and the carrier tray matched to your chassis generation. Keep SSD and HDD groups separate on the controller rather than mixing drive types inside one RAID set, because an array runs at the pace of its slowest member and the flash advantage disappears entirely.
HP P18422-B21 480GB SSD for the Flash Tier in a Hybrid Server
For a machine running flash and spinning disks side by side, this is sized for the fast half of that pairing. 480GB of Read Intensive SATA storage in an SFF bay.
