A few days ago I’ve hooked-up my newly bought Intel SSD drive to one of my ESX server but didn’t realize it was the one with an ICH9 SATA controller. After some first tests I was a bit disappointed with the outcome, only 150 MB/Sec. After exchanging some email with Simon Seagrave over at techhead.co.uk who also has bought an SSD drive, I realized I was using the wrong ESX server. The SSD drive is now hooked-up to a server with an ICH10 SATA controller. I quickly fired-up the servers to see how fast the SSD drive is running now and it really matters. The difference is significant.
