Hello,

Any in the market? ...Looking for Fibre Channel single disk drive to run at 2Gbit/sec and write at about 180MByte/sec... Capacity 900GByte and over... Thanks.

Not likely possible, except possibly with fastest (most expensive) devices. Discs cannot physically write this fast. With appropriate cache on-disc, you can write small amounts to the disc at those rates, but the buffer cache will saturate quickly and the throughput will drop to the raw data write speed of the disc, which depends upon the rotational speed of the drive, number of heads, and such. My high-end 7200rpm drives can sustain a bit over 60MBps in write speed. If you have 15K drives with more heads, then 120-150MBps sustained may be possible, but the OS (disc drivers) will have to handle it as well, which also gets into the I/O channel speeds. IE, it isn't just a disc issue, but an entire system issue.
