Re: Real world performance impact for SSD opposed to spinning drives

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

My guess is your going to be very pleased.

There’s a tool call disk magic from IBM that you or your partner could use
to some predictive modeling on if you want more specific results.

Honestly I doubt I would spend the time.   6 to 5 devices should not affect
the I/O channels enough to make a difference plus the speed of the SSD vs.
spinning drives.

Go for it.

I’ve done this for other customers and the performance difference has been
almost shocking.

Not to mention the difference in CPU.
