Any good 64-bit SATA controllers?

[Chaotic42]

Just curious. Debating on this versus SCSI, but it needs to be 64bit 33MHz, and needs to work with Linux.

Thanks.

Yeah. 3ware sells several. But they cost $$$. Don't know about linux compat. You know, sata isn't really hardly any faster than pata except for the WD raptor. There's no substitute for SCSI if you need a really high transaction count.

i agree, with the dearth of SATA drives on the market now, it is nearly useless getting a high-end SATA controller. you are probably better off with an ATA card and JBOD or RAID 1 setup of ATA hard drives if you want cheap bulk storage or SCSI for higher end storage. my raptors are humming along in RAID 0 right now with the builtin SATA controller. if you were to add the cost of a 3ware SATA controller to these two raptors, it would be more cost effective to get a 15K SCSI hard drive with a decent SCSI card and you would get the same performance.

Hmm, well, I was going to go SATA based on the fact that I thought it would be much cheaper than SCSI. Whatever I choose, it needs to be 64-bit, because those are the only slots I have left, and I'd rather not slow the bus down if I ever get a gigabit NIC or something similar.

Thanks for the replies.

I'm not sure if the Promise Ultra 150 TX series can do 64-bit. I know that can go between 33 and 66 MHz, I'm just not sure about jumpin between 32- and 64-bit.

32-bit

You can put a 32bit card in a 64bit slot. Bit of a waste of a 64bit slot, but if it would otherwise be empty...

A 32 bit card in a 64 bit slot won't slow down the bus much - well, it will slow it down more than a 64 bit card in a 64bit slot, but it would be exactly the same as a 32bit card in a 32bit slot.
