Greetings,
I am considering buying some 250G SATA drives (3 in a RAID5 config)
for multimedia backend storage.
disks will likely be WD SATA WD2500JD unless somebody points out good
reasons not to. Can get those for about 200 Euro excluding VAT each.
This is going to be used to store interactively accessed MPEG2 video
files. They will be stored from at least 2 (on short notice 3)
sources, and simultaously read from 2 or 3 locations. In other words:
storage backend for a MythTV setup with 2 or 3 backends, and multiple
frontends using a combination of PVR-250 and PVR-350s. 350 for
frontend connected to a TV, several frontends using X for output.
The controller i am considering is the Promise SATA TX4.
kernel: 2.6.4 or later from kernel.org on a recent slackware-current
distro.
Any experience, either with this controller, with SATA, with other
controllers, please share so I can make a better decision. I've
currently no real experience with SATA.
Filesystem choice has been made: Reiserfs3. This is going to be a
production machine, I will not yet test Reiserfs4 on that. Too risky
considering "comments" i would get on failure...
Regards,
Rudy
xfs might be better for this than v3, to be honest. delayed allocation
matters for this workload.
