I am running 4.7 stable with 10 HDD (9 storage + parity).

The parity and first 5 storage drives are connected to the motherboard and the other 4 storage drives are connected to a promise tx4/300 pci card.

 

I am only getting 2.5MB/s read and write speeds to the drives on the tx4.  These are the copy speeds shown by windows and the same when I run hdparm in the terminal using telnet.

 

Does anyone know why this would be happening?

 

My hardware is:

Asus P8H67-M-LEV3 H67

Intel Core i3 2100 3.10Ghz

OCZ 4G (2x2G) DDR3 1333 PC10666 Gold Edition LV

Fractal Design Define XL Full Tower Black

Cooler Master 600W Silent Pro Modular

Promise TX4/300

 

I have included the hdparm results:

Promise tx4:  sda sdb sdc sdd

Onboard: sde sdf sdg sdh sdi sdj

Flash drive containing UnRAID: sdk

 

All hard drives are Seagate SD2000DL003

The first 8 storage drives are full (except the 80GB free I told UnRAID to leave)

The 9th is ¼ full.

syslog-2012-2-2.txt

Swapped the tx4/300 for my spare tx4/300 and copied a file at 79MB/s to windows.

 

All sata cables were plugged in to the same port on the card and all drives are in the same order in UnRAID.

 

The other card must be somehow faultyv(the first was bought 2 years before the second) so it may be firmware.

 

Not sure which is the old and which is the newer one.

 

SOLVED

 

If anyone has knowledge on what the problem with the first card was, please post or link to a solution.
