pci express SATA controller questions

Recommended Posts

This is definitely going to sound like a noob question but so be it.

I've just upgraded my server from 5.x to 6.x and am having issues with my drives red balling.  I'm also getting reiserfs errors.  I'm concerned that it is my SATA controllers and I'm prepared to leave the system offline while I research & purchase a new controller.

Current config:

mobo is from a Dell inspiron 530s

processor:  core2due e4500 @2.20GHz

BIOS:  Phoenix-AwardBIOS v 1.0.3 07/12/2007

 

My first four drives are on the mobo

 

first SATA card

rocketraid 622sd 1126M64114173

rocket 62X

RocketRAID 62X/62XM

si-pex40064

 

second SATA card

syba SD-PEX40054

 

The motherboard has two PCIe slots.

One is x1 & x16 but I believe both are 2nd gen

 

The rocketRAID controller has no BIOS support to drop it into JBOD mode so I use a script documented here:

On top of the errors I'm also seeing parity check speeds of about 10mb.

 

Here's the question:  Am I right in assuming that an x16 card will give me faster speeds? And, can anyone suggest a card that won't cost more then I've spent on the rest of the very old hardware?
