I'm looking for a 4 ports pci or pci-express (not pci-x) sata controller with these features: - real hot swap support - no RAID support, or with RAID support that can be disabled through the controller bios interface or reflashing the bios

My need is to hot plug/unplug one or more different sata1 and/or sata2 disks from different brands size and speed (even at the same time), coming from my customers computers to perform lab activities on them, like backup.

I tried several Silicon Image controllers (3112,3114,3124) and Promise TX4. Everyone has issues: some disks are not seen or are dropped during the backup process while the Promise even hangs the host pc with some hard-drives. Adaptec raid (Serveraid 8s) controllers aren't transparent to the operating system and it seems there is noway to disable the raid.

What would you suggest?

Thank you!

what is the host OS? – iPaulo Feb 18 '10 at 17:34
@iPaulo it's a debian lenny 64bit – dam Feb 19 '10 at 0:18
Did you find something? Did you try the Areca ARC-1300-4e? – iPaulo May 24 '10 at 23:28
yes! I bought a Silicon Image 3124 Addonics multilane PCI-Express ADSA3GPX8-ML. It works very well! – dam May 29 '10 at 21:52
and no I never tried the Areca. Do you have any report about it? – dam May 29 '10 at 21:52

Did you consider a SAS card? They usually allow also SATA.

Could something like Intel SASWT4I (WILDWOOD TRAIL) fit the bill? I have absolutely no experience with it, but on paper it does everything you need.

Have had sucess with this card LaCie 2Port They also make a four port but it is not inexpensive. Have had issues with some Startech cards not allowing Dell servers to boot and have not found a solution.

Have you considered a SATA USB Dock? http://www.thinkgeek.com/computing/a7ea/

Not sure what performance you are trying to achieve but this could be handy.

yes I did, but usb is too slow for a professional use and all those devices are too much fragiles: they are not supposed to be used several thousands times in a year. Thank you anyway. – dam Feb 19 '10 at 0:21

As you mentioned fragility in a comment: Be really careful, as SATA plugs aren't supposed to be used thousands of time, in fact they are really fragile, as I have learned the hard way just two days ago.

For this kind of use I would try to find a controller with e-sata ports since they are designed for much greater stress.
