SSD cache Plus RAID 1

post #1 of 3
Thread Starter 
Having to build a new system as old Mobo has died. I'm thinking of an i5 2500 on a P8Z68-V/Gen 3 board with 16GB of 1600. I have always set up RAID 1 as computer is used for work rather than any gaming, but am considering using a small SSD cache to speed access to common things. However, some descriptions refer to needing the RAID controller enabled for this. Does that mean I cant use it for RAID 1 set up for 2x 1TB SATA III drives?
Also slightly unsure if, in using RAID, the SATAs will operate at 6GB, some tend to hint that 3GB is the maximum, in which case I might as well put the RAID drives onto the SATA II headers....many thanks
Any other tips :-) ?

I am currently researching this myself.
Intel caps the cache at 64gb so don't bother using a ssd bigger than that or it will partition off the rest for you to use seperatly. Intel is selling a special drive at 20gb made for a longer life span as the cache drive will be constantly writing and reading whats on the HDD.
The cache must be set up from within windows, its a software layer and not in any way is dependent on any special hardware on the z68, its actually artificially bound by Intel to that specific chipset.

For you I think you should be absolutely fine with what your trying to accomplish. Enable Raid in the bios and set it up for raid 1 on your drives, install windows on the raid array. Then after restartign and such, install the SSD, initiate it in disk management and then set it up and use it as a cache drive.
The bios needs to be set up for Raid as it incorporates AHCI mode and other essentials for running multiple disks together. This will not effect your Raid array at all when the ssd cache drive is functioning.

My situation is a little different though, what I'm going to attempt is setting up my chronos 120gb ssd on the sata 3 as c drive with windows installed, I'm going to partition the drive with 20 gb left over for a second drive that I can use as a cache drive... cache drive for what you say? My Raid0 array caviar blacks on the sata 2 with all the room to store my games. I am just wonering the effects of partitioning a ssd, is it the same as a hdd or is the partition more theoretical and the data is written to the disk as if the partition wasn't there at all. If all else fails I can just install my old phoenix pro sata 2 as a cache drive for the hdd array and leave the chronos as the c drive with no partitions.

I've done a lot of searching on other fora and the conclusion is that using SSD cache with a RAID away inevitably leads to an unstable system, sometimes immediately, sometimes an hour or so down the line. One person has even has a conversation with Gigabyte with it and was eventually told it was not possible. The conclusion was from MoBo mfr and users that there is a problem with the Z68 in this regard
