Has anyone tried RAID100?

As in 2 RAID10 arrays in RAID0. You will need at least 8 drives. If so how's the performance? Just curious.

Sexy.
Why? Won't this just be like putting the discs into a bigger raid 10 array?
lol
Plaid RAID can be good for large database servers. I think that I'd probably stay with RAID 10 for Web servers though.
.
How about four RAID10 arrays in RAID10?
16 disk minimum (:
No I think he means RAID10 with 4 RAID1 mirrors which would be faster than 4 drive RAID10 of 2 RAID1 mirrors. You stripe over 4 sets of drives instead of 2.
Performance of 8 drive RAID10 vs 4 drive RAID10:

Ah yes true that. Got slightly confused with the ordering. Stand corrected. I've seen 6 drives in RAID10 being slower than 4 drives in RAID10 but.
Yep I have played with Raid 100, 2 x HW Raid 10 arrays (6 disk per array) in mdadm raid 0, close to 1GB p/sec sequential.
Not sure I would trust mixed raid for production though, if I was going to do this for anything but fun it would be a full mdadm set up, a controller that supports raid 100 is as rare as rocking horse shit and twice as expensive.
Sounds fun. Don't have a spare server with that spec to play with right now, otherwise would give it a try too.
It worked right? Not compatibility issues. Was it simply a test?
RAID 1010?

Pretty much linear as stated in WHT thread, more spindles = better performance. Tried it myself with 8x 60GB SSD raid 10 + LSI 9260-8i
RAID´s everywhere...
