Optane 905P 1.5TB AIC SSD

The Intel Optane 905P 1.5TB add-in-card SSD is built for desktop and workstation users who need consistently low latency. It uses 3D XPoint memory and a PCIe NVMe 3.0 x4 interface to deliver up to 2600 MBps sequential read and 2200 MBps sequential write speeds. Random performance reaches 575,000 read IOPS and 550,000 write IOPS at 4KB. Both read and write latency are rated at 10 µs.

PCIe NVMe 3.0 x4 interface limits

The drive connects through a PCIe NVMe 3.0 x4 slot, so maximum throughput is bounded by that generation's signalling rate. Sustained workloads will not exceed the 2600 MBps read or 2200 MBps write ceilings, and random IOPS top out at the quoted 575,000 and 550,000 figures. Active power draw reaches 18.6W while idle consumption sits at 6.2W, which the host slot and system cooling must accommodate.

Upgrading from NAND NVMe SSDs

Moving from a conventional NAND-based NVMe SSD to this Optane 905P replaces variable latency with a steady 10 µs figure for both reads and writes. The jump is most valuable for workloads sensitive to tail latency, such as database logging, real-time analytics or high-queue-depth virtualisation. Endurance is rated at 1,600,000 hours MTBF, reflecting the durability of the 3D XPoint medium.
