HPE 512GB SATA 6Gb/s 2.5-inch Hot-Swap SSD (704638-001)

The HPE 512GB SATA 6Gb/s 2.5-inch Hot-Swap SSD delivers fast, reliable storage for HPE ProLiant servers. With a SATA 6Gb/s interface and 2.5-inch small form factor, it offers sequential read speeds up to 500 MB/s and write speeds up to 400 MB/s, making it ideal for read-intensive workloads. Hot-swap capability allows drive replacement without downtime, and the HPE Smart Carrier ensures easy installation and management.

Advantages

This SSD provides high endurance with a TBW rating of 1310 TB and a mean time between failures (MTBF) of 2,000,000 hours. Its 3D TLC NAND flash technology balances performance and cost, while the read-intensive design suits applications with a high read-to-write ratio. The 2.5-inch form factor fits standard server drive bays, and hot-swap support simplifies maintenance.

Suitable for

• HPE ProLiant Gen8, Gen9, and Gen10 servers
