Title sorta says it all. For quite a while I've seen issues where my disk utilization would spike to 100% and basically bring the system to it's knees. Any moderate disk writing would do this and the system would be almost unusable until the operation finished. After doing a lot of reading I grabbed Crystal Disk Mark to get some benchmarks to compare to a friends system (identical build save for he's not doing RAID). To make the numbers easy I'm getting around 700 mb/sec read times but a horrible 8-10 mb/sec writes. It's like a 100x difference between the two.
I've tried the following with no luck
- Disable write caching
- Verified all drivers are current
- Verified BIOS was current
- Made sure I'm using the Intel SATA ports and not the ASMedia ones (disabled those in BIOS as a test)
- TONS of research
I setup the RAID0 array in BIOS with 2 240GB (PNY XLR8 240GB drives, both identical). At this point I'm totally stuck and hate to admit it but I have no idea where to go next. It's extremely frustrating as otherwise it's an amazing machine, specs are:
Core i7 4770K 3.5Ghz
32GB 1867 MHz Ram
Nvidia Titan Z 12GB video card
2x 240GB PNY SSD drives
Bluray / HD-DVD burner
What am I missing? I feel like there's some silly check box somewhere that I haven't checked, I did poke around in BIOS but didn't see anything that jumped out at me. Any input would be greatly appreciated as it's so frustrating to have such a high end machine that's capable of so much yet have one silly thing like this bottlenecking it like crazy. Fortunately it's not affecting gaming too much since games are almost all read operations (and that's screaming fast).
Thanks for any ideas!!!
