Hi all i recently got a 120Gb OCZ vertex plus.
there was no AHCI mode in my BIOS so i went ahead and installed windows 7 and all runs well.

My question is could or should i go into BIOS and swithch to RAID. what would be the benifits of swithcing to RAID if any. what to do before switching to RAID.

Also i set my paging file to 4000Mb max and 2000 allocated on my 500Gb HDD. I have 4Gb of RAM. is this the correct configaration.

many thanks

If this was an Intel based system, no problem as Intel will install a intel ahci driver when the bios is set to raid as long as the SSD is not a member drive of a raid 0/1 configuration.

You have a AMD chipset so not sure if amd also supports ahci when bios is set to raid.

Best option, unless someone else chims in that is more familar with AMD chipset:

First what mode is displayed when raid is NOT selected, if it states IDE, you DO NOT want that.

If Mode is unknow, try installing. after install download and run AS SSD and look in upper left (DO not need to run benchmark). if it is IDE it will also state "BAD".

Worst case is you would then have to re-install windows but with the BIOS set to raid and HOPEFULLY amd will have a equivalent driver for ahci mode that can be installed.

Hi thanks for your reply. i ran the benchmark and it say nvstor-ok. i asume the NV is nvidia. it does not say IDE.
this is my bench mark in txt form

First and foremost it is still way faster than a HDD!!
.. Yes 500 mb/s seq speed sounds impressive compared to your 203 - BUT Seq Performance is the LEAST important performance matrix for a OS = Program drive. Over 50% of your files will be under 32 K and a good % under 8 K and they are Randomly spaced. Reason RANDOM reads are the most important matrix for Booting into OS. And your Random reads are still 14 X faster than a HDD.

Not sure, But I think you are limited by SATA II interface.
Also while the Nvidea driver works it is NOT optimized for SSDs.

To get the "ADVERTIZED" performance the SSD would need to be (A) on sata III (6) and (B) on an Intel chipset, running the latest intel RST driver. (NOTE AMD driver is close)

Worst driver is the "marvel" driver for the older SATA III (6) Pci-e card (I have one) and the NVidea driver.
