Hi guys
I currently own an 80gig intel 320 drive. I've just bought a 330 series 60gb drive which i am going to put windows 7 64 bit on. What i want to know it which ACHI drivers should i use? I will enable it in bios, then install windows onto the 60gb drive in a sata 6 slot. The 80gb drive will be for my games and is sata 2. Do i need to do anything regarding achi apart from this? Can i leave it as it is or do i need to install the intel RST drivers upon installing windows?
Cheers

It would 'help' to install the Intel AHCI Driver (provided in their "f6 boot disk" zip package), however it is not essential since Windows 7 provides a half decent driver anyway.

Can you link me towards the relevant F6 driver i need to use please?
Also which RST version should i use? The latest or an older version? I heard the newer version causes problems for 320/330 ssd's with BSOD messages.

Well i set ACHI mode in bios, installed windows, install the intel INF, installed the intel RST drivers
and ran crystal mark and these are my results.[IMG]http://i.imgur.com/CJlN0.jpg[/IMG] http://i.imgur.com/CJlN0.jpg[/IMG]

I was expecting much better write speed results from my 330, which is supposed to do 450mb. As it stands my Intel 320 with 100mb write is faster. What gives?

You're seeing the affect of using all incompressible data in that test on a SSD with a SandForce controller.
If you check Table 3, page seven of this document: http://www.intel.com/content/www/us/en/solid-state-drives/ssd-520-specification.html?wapkw=520+ssdht... http://www.intel.com/content/www/us/en/solid-state-drives/ssd-520-specification.html?wapkw=520+ssdht...
you'll see that the sequential write spec for the 60GB 520 with all incompressible data is 80GB/s. All SSDs that use SandForce controllers will work this way, their performance is lower with incompressible data. Also, smaller capacity SSDs have lower write performance than larger ones. Intel is one of the few that actually put the incompressible data speeds in their specs.
For the average user, more of their data is compressible than not. Try ATTO Disk Benchmark to test your 520, it does not use incompressible data for testing.
