What this drive is

The Intel Optane SSD 905P 1.5TB is a 2.5-inch U.2 internal solid-state drive that connects through a PCIe NVMe 3.0 x4 interface. It uses 3D XPoint memory and an Intel controller to deliver sequential reads up to 2600 MBps and writes up to 2200 MBps.

Who it suits

This drive is built for consumer desktops and single-user workstations that need high random performance, with 4KB random reads up to 575,000 IOPS and writes up to 550,000 IOPS at 10 µs latency. Systems without a U.2 backplane or PCIe NVMe 3.0 x4 support cannot install it.

The deciding spec

The U.2 form factor combined with the PCIe NVMe 3.0 x4 interface determines compatibility; the drive only fits bays and motherboards wired for that exact connector and protocol.

Highlights

  • Breakthrough performance with up to 2600 MBps sequential read speed
  • Responsive workloads from 575,000 IOPS 4K random read performance
  • Low 10 µs read latency cuts processor wait time
  • High endurance backed by 1,600,000 hours MTBF
  • 5TB capacity in 2.5" U.2 PCIe NVMe 3.0 x4 form factor
