***************************
I thought I would be able to set a number of drives writing to my ram drive
with no problem but as soon as I start just one additional write to the ram drive
it all slows down.
One seq. write 4GB/sec but 2 writes are slower then what my physical drives are capable of.
Samsung 3TB drives (1TB per platter) can write at 170-200 MB/s.
I guessing some kind of windows file handling issue.
Want to see what others think about the bottleneck.
Thanks
