I'm having problem with the raid 1+0 setup, i set it up in bios and formatted the array when i got into windows. Everything worked out great. Used the optimal setting in the controller bios which is 64k strip size. And used the "standard" cluster size in ntfs format.
I benchedmarked the array and got about 90-95mb/s average transfer rate which is good enough for me. I copied over about 300 gigs of data i had on an external drive. I used the array for a couple of days, installed dc++ and downloaded a bunch of stuff.
Everything seemd fined but a couple of days ago the array slowed down really bad. Now i get about 25mb/s avg transfer speed which is way to low and sometimes as lo as 5-6 and 2-3mb/s
So i did test in windows on the array, came out fine.
Then i went into the raid bios deleted the array and recreated it, formated the drives suddenly i'm up to 90-95mb/s average again.
I copied all the stuff back from the external drive. Everythin went fine. then i installed dc++ and downloaded about 100gigs in 2-3 days. And tonight it started to slow down really bad again?
