I have been using ext4(pre-formatting, no LVM) on my SSDs,
(partitioned using gdisk with some of them,
to ensure the correct alignment)

[root at avon ~]# uname -a
Linux avon #1 SMP

[root at avon ~]# gdisk /dev/sda
GPT fdisk (gdisk) version 0.6.14

Found valid GPT with protective MBR; using GPT.

Command (? for help): p
Disk /dev/sda: 117231408 sectors, 55.9 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 94F57B19-B255-4B3A-A9A0-8983A3A61F04
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 117231374
Partitions will be aligned on 2048-sector boundaries
Total free space is 33343213 sectors (15.9 GiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048            4095   1024.0 KiB  EF02  BIOS boot partition3333
   2            4096        41947135   20.0 GiB    EF00  Linux/Windows data33333
   3        41947136        83890175   20.0 GiB    0700  Linux/Windows data

Didn't bother with /boot or swap (8GB of memory installed on this machine)
Not sure which of the Codes is best/correct EF00 or 0700
The second partition is ready for F15

No known problems

Interested in other replies re btrfs
Does older grub version permit booting from btrfs?
