Testing F2FS With Its Multi-Drive Capabilities

Late last year F2FS picked up multiple device support for this Flash-Friendly File-System. This F2FS multi-drive capability isn't native RAID support like Btrfs but just allows a single F2FS file-system to span multiple devices. But it's more than that in that block allocation and the garbage collection policy is modified to boost I/O performance by taking advantage of the multiple SSD/flash devices.
