Hallo
I have installed a S150 SX4 Fasttrak with RAID 5 (3 Harddisks 160 GB).
After I make insmod FastTrak.o everything works but the writing speed
(dd if=/dev/zero of=test bs=1M Count=500 -> needs 170 seconds)
is very slow about 3-4 MB/s. Reading is very fast 50 MB/s.
I have a AMD 2600 with ASUS A7N8X Board.
What for writing speed I should expect ?
Do anyone have solve this problem ?
cat /proc/scsi/FastTrak/1
Promise FastTrak S150 SX4 Linux Driver Version 1.01.00.57 (4.Aug.2004)
Adapter1 - FastTrak S150 SX4
Adapter2 - - (unknown)
Array - Array[1] : 2+1 Raid 5 (OK-Gigabyte Boundary)
