Micron's P320h solid state drive (SSD) is targeted at applications that require high performance and enterprise-class storage reliability. The P320h delivers extremely high IOPS performance due to its ability to support up to 256 outstanding commands while ensuring full end-to-end data protection. The P320h comes in a half-height, half-length (HHHL) form factor and uses a second generation (Gen 2) PCIe x8 lane interface on the host side and 32 ONFI 2.1-compliant channels on the Flash side. The single-chip, Micron-developed ASIC controller, along with the host and Flash interfaces, provide an embedded ATA host bus adapter, a host/Flash translation layer, Flash maintenance, channel control, and Flash RAID (RAIN) protection. Flash endurance and reliability are optimized through the Flash maintenance features, including static and dynamic wear leveling and RAIN protection. Most of these functions are implemented directly within the controller hardware to optimize performance. The device is shipped in the configurations shown below.
- 350GB Capacity
- Micron SLC NAND Flash (34nm)
- ONFI 2.1-compliant Flash Interface
- PCIe Gen2 x8 host interface
- Endurance (total bytes written): 25PB
