Micron has introduced the next generation of its SSD.
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.
That is fast.
There is no question: If you don't have a solid state disk as your boot drive, then getting one is the best upgrade you can make.
