Micron initially revealed the new RealSSD P320h at SNW in May. The drive is expected to ship in the third quarter of this year.

While the P320h is Micron's first PCIe-based SSD, it is only one in a category of products the company is aiming at the entry-level, midrange, and high-performance applications, such as relational databases and streaming video.
"We'll have a product out soon that will meet the enterprise entry-level category," Dibelius said. Dilbelius did not offer a timeframe for the upcoming high-performance SSD, nor did he say when an entry-level product would be released.
In the meantime, the P320h is aimed at the midmarket, or "mainstream" data center customer, and is optimized for use with Web servers and online transaction processing databases, as well as a server cache, Dibelius said.
Micron's P320h SSD
The P320h comes in 350GB and 700GB models. The P320h is a full-height, half-length PCI card that is 4.3 by 6.6 by 5.7 inches in size.
Using 4KB data packets, the 350GB model boasts an industry-leading 2GBps sequential read rate and a 2Gbps write rate. The drive has a random read/write rate of 750,000 and 298,000 I/Os per second (IOPS), respectively.
The 700GB model has the same sequential read/write rate, but sports a random write rate of 341,000 IOPS, said Janene Ellefson, a product marketing manager at Micron.
By comparison, Fusion-io's full-height, midrange PCIe SSD, the ioDrive Duo, offers up to 1.5GBps throughput and capacity from 320GB to 1.2TB. That card uses multilevel cell (MLC) NAND flash memory, instead of the higher-grade single-level cell (SLC) memory used by Micron in its P320h product.
Texas Memory Systems launched its second-generation PCIe-based SSD last month. Its RamSan-70 SSD has from 450GB to 900GB of capacity and features Toshiba's newest 32-nanometer single-level cell (SLC) NAND flash chips. It produces up to 2GBps throughput, still a full gigabyte per second slower than Micron's drive.
Ellefson said Micron has an advantage over competing PCIe SSD vendors such as Fusion-io in that it has built the card from the ground up using all of its own software and hardware.
"We give Fusion-io all the kudos for opening the door and getting the excitement going around [PCIe SSDs], but we're going to bring high performance to a new level in terms of price performance that will drive adoption," Ellefson said.
Ellefson pointed to that Micron produces its own NAND flash, DRAM and controller, which was built to be compatible with its memory. "That gives us a very good solution," he said. "So there's one throat to choke if something goes wrong."
