The move to 25nm NAND gives us one major improvement: cost. The 512GB C400 will be priced at $825 in 1,000 unit quantities - that works out to be $1.611 per GB. The 256GB drive will go for $425, the 128GB at $210 and the 64GB somewhere above $100. As 25nm production ramps up I wouldn’t be too surprised to see SSD prices drop down to the magical $1/GB price point. Price isn’t the only benefit of the C400, performance should be much improved as well. Micron is claiming sequential read speeds of 415MB/s and sequential write speeds of up to 260MB/s (256/512GB drives). The 128GB drive is good for up to 175MB/s sequential writes. Random write performance is unknown at this point but I heard Micron mention something around 50,000 4KB random write IOPS. |
