Im still learning a lot about computers, so I was just wondering. Say I had 2 120gb SSD's as well as a 250gb HDD, or maybe 250gb ssd. Would there be anyway to run the 2 SSD's in raid 0 for the increase in performance, but then put that raid config in a raid 1 with the third drive, so that you would get all the information. Im familiar how raid 0/1 works, and i know it wouldn't really, but is there someway to set it up so that I could essentially copy all the storage from both drives, into that single drive? This way I'd have the raid 0 speed, with the backup of raid 1 as well?
I haven't done it before but i do know that you can do a raid 0+1 function.
Basically you do a raid 0 with the dual ssd's. Then you make another raid aray with the dual ssd's and the 250gb hdd. Though after the math is done with the dual ssd, you're going to have to exactly match after the loss. You don't exactly get 240gb after raid 0..more like 221gb. So you'll turn the 250gb hdd into 221gb and then i guess you can use the left over as a scratch disk.
That would be my way of doing it. I'm not 100% sure if a z87/z77 board could do that, but my Gigabyte 990fx-ud3 can't at all, just raid 0, 1, 5, and 10. AMD doesn't support raid 0+1 as far as i know...i've built on a ASUS Forumla Z which doesn't have that function 100%.
if i were you i would look into raid 0+1 because i'm pretty positive i'm off a bit.
i dont think onboard raid can pull that off, but dedicated raid cards? maybe. hope someone knows.
raid 0 + raid 1 = raid 10, doable in linux with only 2 drives, in windows only doable with 4 drives.
How do you do raid 0 and raid 1 with 2 drives? Raid 0 combines 2 drives to double the space and increase speed, and raid 1 mirrors the drives. Unless the drives were heavily partitioned, that wouldnt work.
There's no point in doing raid 0 with SSDs, just to slow them down by doing raid 1 with a mechanical drive. To benifit from haing SSDs at all, ALL of the drive would need to be SSDs.
Raid 0 the drives, then raid 1 the drives with the other one. Like stated before. If that doesnt work, Do raid 0 in UEF/BIOS then inside of Windows/Linux whatever, Change the second drive to a dynamic disk, and mirror the first one.
Just with mdadm, the standard linux software RAID tool. There are actually multiple options to make this work, depending on block format.
With linux, 1 SSD + 2 HDD's can offer a pretty good solution. Linux can use a standard SSD like a high performance hybrid drive, there are a couple of standard tools for that.
Yes, but OP proposed 2SSDs, and 1HDD. Which would not benefit.
Well you can get good performance boost but you're going to have to turn some RAM into a cacher...mainly because since the hdd doesn't perform, you can make it up with a ram disk....something like a 2gb ramdisk would be sufficient. Then you cache with the ram onto the hdd and possibly get a performance boost. I'm not entirely sure how well intel does it on their z87 platform. I've seen those things work on a workstation board so my best bet is this might be a workstation function. I think you can turn ram into cache for hdd through software like AMD Ramdisk or other programs that work that way.
Thanks for all the help guys, I kind of dumbed out, not realizing that the raid 1 would basically cancel out the performance boost of having it, even if it was with another SSD, but thanks for all the input.
