I have a Work PC I tossed an SSD in hoping to get better speed. It feels a little fast but not much so I ran ASSSD and found peaks reads and writes of around 90mbs? I did fail to set the controller to AHCI before loading but even in IDE mode on other PC's I had no problems hitting high speeds. The PC is a HP DC5850 small form factor and it says it has a SATA 3.0gb controller which I thought would be good up to 270ish? The drive is a Micron C400 with 0809 firmware. I tried updating the firmware with the update from the Micron site but it keeps saying no ssd found. Thx for any advice!
