What's the maximum length of a SATA cable?
know of any `four device' SATA adapters for RAID?
That is two RAID-0 pairs?

Thank you.. was all set to build a four-disk array of two IDE pairs
(two RAID-0 drives) on a single FT100 TX2 card.. but the 18" cable
length limit prevented it. Have been asking around for months and
years if going over the 18" length (to 24") is ok? for overlength IDE
ribbons with both MST and SLV devices connected. The answer is
always.. NO - it violates the spec .. except for the vendors who want
to sell cables.
Still have not built the file server with four ATA-100 drives on the
TX2 card that requires 24" ribbons.

I've done it several times using rounded cables with
twisted-pair construction (any decent cable will be built
this way). Use shortest cable possible. It will also help
that you're running in ATA100 instead of ATA133 mode.
Solution: Get a better case.
I have a 6-port Promise RAID card (PATA), and in a full-
tower case it was a real pain to get those cables up
into the upper drive bays.
Instead, look at cases like the Antec p160, Antec
Sonata, or Antec 3700-something where there are (4)
drive bays down at the motherboard in the lower-half of
the case. (I own 3 p160 cases and a single Sonata
case.)
In addition, they have a spot to install a 120mm fan so
that you can pull air in from the front, and it will
flow directly over those internal hard drive bays.
thanks.. I've read a lot about the round TP cables.. and agreed it
helps with ATA100 vs 133. The thing is.. what about FOUR drives on the
cables.. the 18" limit.. the position of the SLV device on the cable..
and of course.. having two RAID-0 pairs.. one pair MSTR and the other
pair SLV configuration. That is the issue. I'd not hesitate as much if
it were simply a drive at the far end of each ribbon.
The case I bought was for the Linux gateway.. that is before
inexpensive NAT devices came along. The TOWER is a mighty
SuperMicro which has up to nine fans. Try out a google search for
SuperMicro Case or SuperMicro Tower and you'll see these awesome
(yet expensive) boxes.
