If Internal drives, unless you can identify the chipset, I'd avoid this card and go for something else. If external drives, then it's worth trying to find-out what the underlying chip-set is. Personally, if you have 8 external drives, I'd consider SCSI, just to cut-down on the number of cables! (Although the cost of the drives might well be a factor for you, as it is offten for me )-: If internally, I'd go for a board that has open-source drivers. I've just been trying the Highpoint 4-port card - no open source driver, and their own supplied Linux driver is some 10-15% slower than another SATA card (SII chipset) and didn't support SMART command pass-through. If your motherboard has multiple PCI buses, you might want to look at 2 x 4-port cards which will probably improve performance somewhat if you can get them on separate busses. The cheaper cards that I've used seem to have mostly the SII chipset - and that appears to be well supported by Linux. The 3112 is a dual-port card, the 3114, quad. There are RAID and non-RAID variants, and all the ones I've used seem to have a JBOD mode anyway (so you use s/w RAID rather than their supplied h/w RAID) (The exception would seem to be the Dell/Adaptec 6-port SATA card I had recently - it has 3 x SII 3112 chips on it, and a big Adaptec/Dell chip which hides them from bus )-: Gordon - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
