Today Micron finally made their PCIe-based SSD official, releasing a 350GB and 700GB version targeted at enterprise markets. The Micron SLC-based P320h will be capable of 750,000 random 4K IOPS read and 341,000 IOPS write, with up to 3GB/s sequential transfer speeds.

Earlier this year we got a chance to see the Micron RealSSD P320h up close and personal at SNW Spring 2011. On the show floor we saw the model with 512GB of raw storage capacity, giving the 350GB model roughly 32% of over-provisioning. That helps to explain some of the incredibly high endurance figures Micron quotes for the P320h, supporting 28TB of data written to the SSD each day over a span of five years on the 700GB model. To put that in other words, that is almost half the TBW value for the Crucial m4, written each day… for five years without failing.
Micron RealSSD P320h Specifications:
- Capacity: 350GB, 700GB
- Interface: PCIe (Gen2-compliant) x4, x8

- Random up to 750,000 IOPS READ/ up to 341,000 IOPS WRITE
- Latency: <50μs
- Active Power Consumption: 25W max
- Idle Power Consumption: 6.1mW
- MTBF: (mean time between failures) 2 million device hours
- Operating Temp: Commercial (0˚C to +70˚C)
- Form Factor: FHHL
- Dimensions: 111.15mm x 167.65mm x 14.47mm
Pricing has not been listed yet, although don’t expect these enterprise-class PCI-Express SSDs to come cheap. Fully loaded with SLC NAND, these drives will command a much higher price tag similar to the RealSSD P300‘s we reviewed earlier this year. Micron puts full production to start in the third quarter of this year, with some earlier samples starting to ship now.
