TRIM mode is supported only if your hard drive is not part of an array. In this case, you will accelerate your SSD hard drive and this will become RAID 0.
Could you elaborate a bit more on the whole setup.
The main question was actually about splitting the SSD into two parts - data section(acting as a boot drive) and cache section.
I have since found that technically there is a way of doing, it's just WAY too complicated.
Are there any plans to simplify that process?
I also read that intel plans to add TRIM to RAIDs in with an upcoming RST update. Is there a time frame to that?
I have a RAID1 volume in an array accelerated by an 18GB volume on the SSD - the remaining 65 GB (90 GB SSD) have been used to install the operating system.
What I did was to boot with the old operating system, enable acceleration on the SSD - this created the two "RAID 0" volumes (I've put RAID0 in quotes because that is the way they are displayed, even though there is no RAID0 array, only two volumes marked as "data" and "cache") , and then boot with an OS install disk to install on the remaining space.
It doesn't seem that complicated - the only issue is that you need an OS to be installed on the HDD before configuring the acceleration.
