I currently own 2 500GB WD5000AKS HDDS and I want to set them yp in Raid-0, but I researched that without the TLER the errors will be massive, and the HDDs were manufactured in early 2010 so the WDTLER utility is out of the solutions list, I havent install anything yet, just wanted to check with you guys to hear some suggestions before getting into it. My mobo is a MSI big Bang Trinergy

I wasnt sure what TLER was Wiki'ed it and it shows how to turn it off for a 500GB drive doesnt say anything about drives made in 2010. Personally I have not had any TLER errors on a raid between a 1600AAKS and a 160AAJS, or on my new RAID array of 3x 6400AAKS. You cal always greate the RAID and test it out if it gives doesnt give you any...

Hard drives for RAID are commonly said to benefit from TLER (time-limited error recovery) but I believe this does not apply to RAID 0. To the contrary, a RAID 0 setup, because it has no redundancy, can't afford to limit error recovery. So I believe that the TLER settings of RAID/Enterprise class hard drives are (at best) useless with RAID 0.

If this interpretation is correct then you're lucky that your year 2010 WD drive is non-RAID/Enterprise class. The WDTLER utility doesn't work with it, so you can't limit error recovery to 7 seconds, which limit you don't want with RAID 0.
