I'm surprised my burst is so low. AlsoI've never seen mechanical hard drives so stable over hd tune, as in no peeks and valleys, is there something going on there?

Its b/c of your short stroke that you are seeing it so consistent. Run it across the whole disk or the remainder of the drive and you will see the typical slope of degrading performance.

Lol, and i bet my single SSD is still faster at loading due to the access time being 800x lower :rock:

Still not bad at all. It'd be great for anything that requires a lot of sequential read or write.

80x faster. ;)

.1 vs 8.x

yeah it's a photoshop pc. used for a lot of large .psd documents ect. just got the RAID going and i love it. Windows 7 gives me a HDD rating of 6.5. Not bad at all for mechanical drives.

back up most files as i use then on a networked server, so the reliability problem doesn't really bother me, also acronis true image is a good way to protect yourself with a once a week clone of your PC.

have an i7 920 do at 4.2 ghz and 12 gigs of mem. this thing fly's multi-tasks like nothing else. for some reason i still page file at times, i like to keep all my apps open at once, so i guess that explains it. I use an old Patriot Warp SSD as my page file disk on an esata external dock. Also do clones on external dock to a crappy 1.5 tb WD green disk. Man greens are crappy HDDs.

do you guys think a RAID card would help at all? obviously it would to some degree but worth the $400 - $500 investment?

I'd want one that would be kinda future proof so when i do move up to a SSD RAID array i can use same RAID card.

RAID cards are good for RAID5/6 performance. It won't help w/ RAID0/1. Those Intel ports are your best bet for anything in RAID0.

RAID 0 on a hardware card helps by getting you on the PCI-E bus but you could get killed in I/O's per second depending on the Card. But it can get you over the Onboard 500MB/s limit.

surprised your not running your 980 faster. I know you don't NEED too, but just for vanity sake I'd try and get it to 4.5 with an H50 cooler. probably stays super cool at 4.0 though. CPU's (and pretty much all computer hardware) are such short term investments, i never really worried about burning em up, getting 2 years out of a CPU is a lifetime.

The H50 can beat out most air with push/pull (or a single good) on i7 wih 8 cores. You up that to 12 and well, that leads me to believe that 12 cores at 4Ghz isnt 'super cool'.

Air - what are your ambient, idle, and load temps? Im curious...
