hi folks.


for kicks i just tested a satalink 3112 based card in a U5/300.  it
seems to work fine.

satalink0 at pci2 dev 3 function 0
satalink0: Silicon Image SATALink 3112 (rev. 0x02)
satalink0: bus-master DMA support present
satalink0: primary channel wired to native-PCI mode
satalink0: using ivec 18 for native-PCI interrupt
atabus2 at satalink0 channel 0
satalink0: secondary channel wired to native-PCI mode
atabus3 at satalink0 channel 1
[ ... ]
wd1 at atabus2 drive 0: <ST3120026AS>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 111 GB, 232581 cyl, 16 head, 63 sec, 512 bytes/sect x 234441648 sectors
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd1(satalink0:0:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA data transfers)
wd2 at atabus3 drive 0: <ST3120026AS>
wd2: drive supports 16-sector PIO transfers, LBA48 addressing
wd2: 111 GB, 232581 cyl, 16 head, 63 sec, 512 bytes/sect x 234441648 sectors
wd2: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd2(satalink0:1:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA data transfers)


for the first GB i could read an individual disk at about 51MB/sec,
read both disks simultaneously at about 43MB/sec, (oop, i didn't test
write _speed_ and it's disconnected again now.)

for comparision, a dual xeon 2.4ghz system could read about 55MB/sec
from these disks and a xscale 600mhz system could read about 45MB/sec.


(i think i'm planning on putting one of these in my U10/440 later
this year.)
