Hi, my question is: what are the drawbacks of having a system configured in RAID mode but with no slave drives (i.e. AHCI would work). Is there a performance drag? If so, how much? Is there a higher chance for system errors or drive failure?
If it matters, the reason I am asking is below:
I recently updated my system from a 1TB HDD with 40GB SRT cache to a 256GB SSD. I moved the 1TB drive to a secondary drive, but made the mistake of unnecessarily leaving the 40GB SRT drive in the machine to cache the 1TB drive. That gave me a config of:
* 256GB SSD
* 1TB 7200 RPM
* 40GB SSD(SRT/cache for the 1TB drive)
About a week after spending 12 hours doing a full reinstall (and 5 more days downloading my company's server) the 40GB SSD drive failed.
Removing the failed drive caused a chain reaction of problems: an EC flash error occurred, and I had to reset the CMOS. That reset the machine to AHCI and it wouldn't boot. I reset to RAID mode, and for my next 3 reboots had numerous startups errors and delays.
The machine is now booting properly and seems to be running at full speed. I really do NOT want to have to reinstall windows again, unless is is necessary.
Thanks for your help!!!
