I bought this because I needed a eSATA port multiplier for my 4xHDD enclosure that has eSATA + USB 3.0.Installed the card in a Win 7圆4 system and it installed default drivers. So, I can't comment on the non-RAID firmware available. We don't need or want the RAID features, but for us the default RAID-enabled firmware seems to be causing to problems. Our cards came with the RAID enabled firmware. I'm thinking about buying several spares to have on hand in case availability of this card wanes in the coming years.PS - There apparently is separate firmware that can be downloaded to this card to remove the RAID features. I wouldn't be inclined to use this card for multiple drives or an SSD, unless you can tolerate the performance hit.Newer controllers exist, but we needed hot-swap reliability under Linux, and this one is delivering. This exceeds the typical IO performance of most SATA drive, so controller performance isn't really a constraint for us. I imagine that it would be so with any version of Linux, even older versions, since the chipset is pretty old.This is only a single lane PCIe SATA II controller, and other reviewers have said its throughput is limited to around 125 MBps or so. This hot-swap card, thanks to its SI元132 chipset, is rock solid. The servers have not been rebooted since the installation of the new hardware. The call to scsiadd unregisters the drive and spins it down too, ready for removal.We have put about 25 hot-swap insert/remove cycles on the servers so far with no misbehavior. To remove a drive, we have a script that unmounts any active partitions, then issues 'scsiadd -r. This allows use of the scsiadd utility (newer kernels can use a script that comes with the scsitools package). We use the Proxmox VE kernel for Debian 6, which still supports the old /proc/scsi/sci interface. You should shut the drive down first to prevent unwanted data loss. With the right hot-plug setup, you could make the drive's partitions auto-mount as well, but we didn't want that for our use.Hot remove also works perfectly. Plug in a drive and it automatically spins up, is registered with the SCSI layer, and its relevant /dev/sdX and /dev/sdXN device nodes get created. We couldn't be happier.Hot insert works great. I coupled these cards with Kingwin KF-1000-BK tray-less hot-swap drive adapters, as part of our off-site backup strategy. This controller is hot-swap capable and nearly plug-and-forget under Debian 6. The drives even obey the windows drive spin down time you have set, just as I wanted.All in all a very good and cheap way to add back in a feature (esata) that even good boards tend to leave out these days.ĥ Excellent hot-swap controller for Debian 6 (Squeeze) I had to set it to gen1 to get it to pick up.After that windows 10 booted and had already installed the drivers needed with no fuss.All 4 of the hard drives in my enclosure came right up so this card definitely supports port multiplying. Turns out my board (z370 tomahawk), is set through bios for PCIE gen3, which this is not compatible with. Purchased this as I wanted to hook up my mediasonic 4 bay enclosure via esata (instead of usb 3).I ran into a few speed bumps getting card to install though.
