Not with proper error correction, and you'll be taking a performance hit, negating the benefits of the RED drives.

If RED drives were good for all situations, they'd have simply replaced the green drives.
Where are you getting that the Red drives don't have any error correction? That is simply not true. The Red drives have TLER enabled, a feature that used to be on pretty much all desktop drives. The drive can still handle error correction on its own, however TLER limits the amount of time it will leave the controller waiting for a response. Drives without TLER will not send a response to a command until after the error recovery is completed, if the RAID controller has to wait too long it will mark the drive as bad and drop it from the array. TLER forces the time that the drive waits to send a response to a much shorter time, so the drive will respond to the RAID controller informing it that there was an error. The controller can then issue the drive a command on how to handle the error correction, but if no command is issued the drive will handle the error correction(remap the bad sector) on its own. There is no lack of error correction on a drive with TLER enabled, TLER was a standard feature in desktop drives for years until WD got greeding and disabled it(and eventually removed it entirely) on their desktop drives to stop people from buying the cheaper drives for RAID arrays.

Unfortunately, no. Though you can pick up a cheap stand-alone RAID controller to set up a hardware RAID if you want.

Something like this: HighPoint RocketRAID 620 PCI-Express 2.0 x1 SATA I...

Mind you, the SATA 6.0Gb/s ports aren't really important since the mechanical drives won't even come close to using the bandwidth SATA 3.0Gb/s provides, but the card is so cheap it is a nice bonus to have SATA 6.0Gb/s ports.

120MB/s isn't even enough to saturate a SATA 1.5Gb/s connection...
