They are not cheap, though ($5000 +).
Simply put, don't use Cat3 for Ethernet. Use Cat 5. Or, since Cat 5 is
deprecated, Cat 5e, which is 100 MHz too, but with enhancements. Or
Cat 6 (250 MHz), or Cat 7 (500 MHz, I think). But then you need to be
rich :)

not too expensive.
Beware : there are network boards with and integrated switch,
too. They will look almost the same, with 4 ports. But they are really
a single port + a switch, not four ports.

We use them in several "appliance like" servers at our customers.
The only drawbacks are :
- capacity (but as you said, for lots of tasks, that's not a problem)
- PIO only. Thus quite slow, about 1 MByte/sec.

Why on earth would you like to do PIO ? It's awfully slow and

hould probably try to time the disk reads, not the buffer cache...
hdparm -t
BTW, on my RAID5 setup (4 drives) with a 3Ware card, hdparm gives
pretty much the same result as a single drive.
I believe that the performance is enhanced in random access, not
linear, like hdparm does.

If it's just a matter of taking a snapshot every few seconds, or using
only one video feed at a time, the usb solution might be ok (as long
as you have at least two buses to connect all the cams). There might
just be a few nasty constants in the device drivers, which should be

s meant to handle one
connection/query per thread. Thus, you will get better results only if
you run simultaneous queries.
Finally, remember that some (not-so-fine-grained) locking happens on
write operations, and that your disk subsystem is hardly
multithread. Database design will make the difference.

mbox will be painful (corruption will happen).
cyrus looks interesting, but once you're there, you can't use anything
else, because the storage format is quite proprietary (although it's
not secret).
So my best advice would be : go for a Maildir based setup. Use your
erent data.
