Indeed, some kind persons donated enough so I have now 4 300MB SATA
disks coming my way, plus a LSI MegaRAID SATA controller. I already
have a machine with 4 empty bays and power to spare, so I expect to
have a setup that's capable of creating large file systems running
soon.
In the mean time, I'm creating some test programs to fill file systems
with files containing simple patterns, so I later check the contents
both by reading and checking the complete file or just by sampling of
some bytes at different offsets.
Thanks to all who donated!
