Intel Optane 905P Series 3D XPoint SSDs Detailed

Ahead of its launch, Intel's upcoming Optane 905P SSD surfaced on Newegg, with 960 GB capacity, and an insane $1,600 price (pre-launch price), and a glowing shroud. The retailer put out close to no technical details of the drive, but leaked documents from Intel website do that job for us. Apparently, the Optane 905P comes in both PCI-Express 3.0 x4 add-on card (up to 960 GB) and 15 mm-thick 2.5-inch 32 Gbps U.2 (up to 480 GB) form-factors.

The drive offers sequential transfer rates of up to 2600 MB/s reads, with up to 2200 MB/s writes. The 4K random access numbers are stellar - up to 575,000 IOPS random reads, and up to 550,000 IOPS random writes, with under 10 µs (micro-seconds) latencies. Drives from both form-factors have a rated endurance of 10 DWPD (drive writes per day). These make the 905P slightly faster than the 900P, which clocks in at 2500/2000 MB/s sequential reads/writes, and 550,000/500,000 IOPS 4K random access.

16.4W for burst sequential writes.
For comparison, Samsung 970 Pro is specced at 8.5W.

I am waiting for Optane drive in M.2 form but that might still take a while.

I'm fine with the U2 format. It's good to keep such a power hungry SSD off the motherboard. But the price is insane.

Yeah, but if the 906P can get the job done in half the time, then yu use the same amount of energy.
Sadly, sequential transfers are not twice as fast as NVMe atm.
