Can I connect 4 drives to this controller and make 2 different RAID arrays with 2 drives each?

I dont know since I only tried one drive in non RAID mode but it will boot windows from the one drive

This card doesn't actually do RAID (it's all done in software) so there is not really any restriction in how you can use it. For instance I used mine with 4 drives connected to this card and another to the on-board controller, for a total of 5 drives in the array.

Yes, there are three options- Speed (Raid 0), Security (Raid 1), Capacity (JBOD) = Just a Bunch Of Drives or like you asked "two disks separately as two 2TB drives". https://www.lacie.com/us/products/product.htm?id=10573

No, I am using it in a non-raid setup. I did try to use it with a 2 TB drive as a 4th drive. It didn't work. I then put a 500 MB drive on it and it worked. I put the 2 TB directly on a standard sata port.

Should not be a problem. upon powering up, push the raid button to your desired array, then hold the button in the back until it re-boots.

You can use the motherboard's onboard controller for booting the OS. This is how I've set up my controller. Only data is stored on the RAID. As for the second part, if you have 2 drives, they can be either striped (RAID0) OR striped (RAID1). If you have more drives, you can configure it in more ways. I use 4 3TB drives in a RAID10 (stripe and mirroring) configuration.

What you're describing isn't RAID, which by definition uses more than one disk. You're talking about disk mirroring, and even that makes little sense with a single physical drive. The whole point of both methods is to maintain data access when an entire physical drive fails.That said, you could set up a meaningful disk-mirroring configuration using this device and 2 of the drives within it. You would access one of the drives, and your mirroring would automatically write identical data to both drives in near real time, which is one level of RAID.

Yes. The redundancy level will vary by the number of drives but you can certainly start with 3 and add more later on.

I would strongly advise Against swapping the drives out for a DR purpose, as there is NO guarantee that you would be able to re-build the RAID on the system in the event that you lose both drives. You would be better keeping the drives singular out of RAID for that purpose, unless you are fully bringing down / rebuilding a RAID each time you swap the drives.. which gets costly / time consuming.

I just used two...one powered the first three buttons and the other powered the other three. You can use either the 4 pin (ATA) or the SATA. If you are only doing two drives....just hook up one side (either 1,2,3 or 4,5,6).

If you want to utilize hyperduo (ssd drives combined with hdd) you need to use the proprietary software or the software from Marvell for this specific raid controller. if you are not mixing drive types/capacity, and want to utilize software raid, I don't see why you couldn't don't use another raid software. The four drives will show up as separate so there shouldn't be any problems. However, hardware raid is usually preferred for better results.

I'm not sure you can span multiple controllers but you can have more than one in your computer. The card supports 5, 6 and 8TB drive.

Not really. You would have to format the existing drives when you added the new ones. What you're describing *might* be possible if you used the JBOD (just a bunch of disks) configuration, but not for any RAID. For all their RAID configs, you have to choose the number and size of disks at creation, and you can't change it without reformatting.

You can configure it as JBOD (just a bunch of drives) and consolidate your various drives. If you configure as RAID, you'll need to replace bad drives with exactly the same size and possibly type of drive

The hot swap functionality should be located in the raid controller not the drives, aside from possibilly energy feature on drive. I think you have drive optimized for network storage.

Yes, you can just use it as a regular SATA controller, you don't have to set up RAID if you don't want to. That's how I use it.

SAS RAID controllers allow using SAS expanders to increase the amount of ports that can be hooked up to the controller. For example, SAS controllers have two 4 port channels. Hook one up to this SAS expander and now you have 5 additional 4 port channels to hook up hard drives. They also can be daisy chained. Many controllers allow up to 128 drives per controller (and they can be SAS or SATA disks). Think of it as an network switch but for SAS controllers.

You can add drives as you need them. The drives can be of mixed sizes too for the hybrid raid configuation; however, I recommend you try to keep to one drive size so select your initial drives with the thought of expanding later.
