Description
HPE P40499-B21 1.92TB 2.5" SSD
The P40499-B21 is HPE's 1.92TB drive in the 2.5-inch size, running at 6Gb/s with a quoted 520MB/s. That sequential figure sits right where any 6Gb/s drive lands. It's also the number that matters least once the drive is in a rack, because server work looks nothing like copying one big file across. UPC 0190017508894 identifies the exact part on an order.
Key Features
- 1.92TB of capacity held in a single 2.5-inch body
- 6Gb/s interface with a quoted throughput of 520MB/s
- 2.5-inch SFF size, built for server and storage enclosure bays
- HPE part number P40499-B21
- UPC 0190017508894 for confirming the drive against a quote
- Internal drive that mounts into a chassis bay rather than connecting externally
Performance and Applications
Sequential speed is what sells consumer drives. Servers run on something else altogether. Twenty virtual machines, a database, and a backup job can all reach the same drive at once, in small scattered reads and writes with no pattern tying them together. Flash answers all of it without a head needing to move anywhere, and that's the real gain over a spinning disk. Sequential figures were never where the difference showed itself.
Compatibility and Installation
You'll need a 2.5-inch SFF bay, a connection on the backplane or controller, and the carrier tray matched to your server generation. HPE codes its drives tightly to particular platforms, so put the full part number on the order rather than the capacity and interface on their own.
HPE P40499-B21 1.92TB SSD for Random I/O in Server Workloads
For a server fielding dozens of small requests at once all day long, this handles the pattern that actually turns up. 1.92TB at 6Gb/s, sitting in an SFF bay your chassis already has.
