I couldn't read WINMAIL.DAT but I use RAID0 and EIDE drives (2.0.36
kernel):
[tim@asus]$ cat /etc/raidtab
raiddev /dev/md0
raid-level 0
nr-raid-disks 2
nr-spare-disks 0
chunk-size 16
device /dev/hdg7
raid-disk 0
device /dev/hde7
raid-disk 1
[tim@asus]$ cat /proc/mdstat
Personalities : [1 linear] [2 raid0] [3 raid1]
read_ahead 8 sectors
md0 : active raid0 hdg7 hde7 6345600 blocks 16k chunks
md1 : inactive
md2 : inactive
md3 : inactive
[tim@asus tim]# fdisk -l /dev/hd{e,g}
Disk /dev/hde: 255 heads, 63 sectors, 790 cylinders

Also look at raidadd(8) and the Software-RAID mini HOWTO.
raidtools-0.50beta10-2 has some samples. Basically add raid to the kernel
pick partitions NOT on the same IDE controller. The only reliability
issues I've had is when I changed /etc/raidtab without reinitializing
/dev/md0, and/or forgot raidstop/start.
Performance is at minimum double the non-RAID0 speed of each partition.
For drives on separate ide controllers with separate interrupts (init 5):
16-17MB/s for large contiguous files. With a single interrupt (Promise
Ultra/33), 13-14MB/s.
