I've been investigating Linux only solutions for mass storage as I'd rather
avoid using ZFS or hardware RAID controllers.

I set up a system using ext4 over a Linux software RAID0, as well as
another RAID5 set. The results are extremely impressive. I was beginning to
worry about my choice of SSDs since the same type of test on Windows 7
yielded a poor result. The biggest thing for me is that it was *extremely*
easy to set up dmraid/mdadm on Linux (Arch Linux). It was versatile, easy
to use, stable, and very fast.

# ext4 over Linux software RAID0 on two OCZ Vertex 4 128GB SSDs:
$ dd if=3D/dev/zero of=3Dtest.bin bs=3D4M count=3D1000 conv=3Dfdatasync
1000+0 records in
1000+0 records out
4194304000 bytes (4.2 GB) copied, 5.54955 s, *756 MB/s*

# plain ext4 partition on a relatively new 1TB hard disk
$ sudo dd if=3D/dev/zero of=3D/boot/test.bin bs=3D4M count=3D1000 conv=3Dfd=
atasync
1000+0 records in
1000+0 records out
