The Pro 2500 will be available in four form factors, as a standard 2.5-inch drive, or as an M.2 drive in 42mm, 60mm and 80mm sizes. In terms of capacity, we are looking a 80GB , 180GB, 240GB and 480GB for 2.5-inch drives. M.2 units will range from 180GB to 360GB. Sequential read/write is 540/490MB/s, with 42k/54k IOPS.
Fultondale is a lot more impressive. Available only in enterprise friendly 2.5-inch and PCIe form factors, it will be available in capacities ranging from 200GB to 2TB. Read/write speeds are impressive, 2800/1700MB/s, along with IOPS of 450/150k. These 20nm HET MLC drives should show up in Q2 2014.
Peasantdale is very similar, but it is not a HET MLC-based product. It will be available in 250GB, 500GB, 1TB and 2TB capacities. It’s very fast, too, 2800/1700MB/s and 450k/40k IOPS. Like Foultondale it will only be available in 2.5-inch and card flavours.
