Axiom SSDEV20HD480-AX 480Gb Enterprise SSD 3.5In Sata

Enterprise SSD for latency-sensitive workloads

The Axiom SSDEV20HD480-AX is a 480Gb Sata solid-state drive built for data centres that run 24/7. It uses 3-bit MLC V-NAND flash to serve mixed-use and read-intensive applications where consistent low latency matters more than peak burst speed. Hot-swap support lets technicians replace the drive without powering down the server chassis.

Sustained performance under continuous load

V-NAND technology keeps IOPS steady during long-running jobs rather than throttling after a short burst. The drive is rated for 1.4 drive writes per day and delivers up to 99K sustained read IOPS and 18K sustained write IOPS. Enterprise-grade power-loss protection preserves in-flight data if the supply fails, while onboard temperature monitoring helps the array controller manage thermal headroom.

Straightforward 3.5-inch hot-swap installation

The 3.5In form factor drops into standard enterprise drive bays and locks with the carrier handle; no cables or adapters are required. Installers should verify the backplane supports 6Gb/S Sata and that the RAID controller firmware recognises the EV200 model, otherwise the drive may appear offline or fall back to a lower link rate. Common issues are mismatched caddies and outdated HBA firmware that disables power-loss protection features.
