To kiwi and other computer-savvy folks on ET: How important is the write speed (sequential and random) of an SSD used in a computer exclusively for trading (including charting)? I already use a Ramdisk to hold the execution and charting programs, and am trying to figure out how best to add/utilize an SSD (with mediocre write speeds) in the current hardware configuration. For instance, Sierra Chart and NinjaTrader charting seem to do plenty of (4K) random writes. Leaving aside the longevity issue, does it follow that putting such a charting program on the SSD, instead of a Ramdisk, is better in performance terms? Thanks in advance for any feedback!
