Backup drive replacement time

I'm currently using a couple of external hard drives for backup purposes. One of them just had its fifth birthday, and now the other one (two years old) is throwing up some read errors periodically in HD Sentinel. This worries me a bit, and I'm thinking about replacing them both with either a NAS box or a little RAID box like this one:

I could also theoretically create a RAID on desktop PC (I've plenty of free SATA slots), but I'm worried about recovery if the entire tower gets fried in a freak accident.

What would you recommend? Complicating matters is that I don't have much space to play with, and my wife doesn't want to devote much more room to computer equipment. That means I could, at best, fit a mini-ITX NAS box in here, and that's pushing it. She's also averse to spending much on whatever solution I develop.

Oh, and am I right that, regardless of what RAID system I design, I want to use something like WD Red drive for it?

A NAS box is a good simple easy idea.

If you setup raid on a PC then make sure you have a UPS battery hooked up to it. In most cases rarely do Power Supplies cause damage because of them. its usually because someone shorts something or a power surge blows on though the PSU. In most cases PSU's these days shut off when any of that happens preventing any damage. Either way a RAID or NAS should work for you just depends on what. A NAS would use a lot less power and smaller but only have 2-4 drive bays on average depending on how much storage you want.

Either way I would get the backup drives replaced. the WD RED drives are good. They are meant for NAS's. They are low power 5400 rpm drives that are still fast for 5400 RPM

Would I need a UPS hooked to a RAID 1? RAID 0 I can see, but RAID 1?



Cool. Is there anything else I should know about them, or any other kind anyone would recommend?

of course.
Both drives will still do many functions at the same time; seek, write...
so if you lose power during one of these operations you can be sure both drives will likely get damaged and *poof* no more data. Raid is not a backup. Its meant to keep your system running in the event of a drive failure.
 
yea if you have valuabe data and your using a low end raid card, especially one that doesn't have a battery for the Raid Controller then yes it is recommened. Now I do run a Raid 0 and i don't have a UPS but i run a Dell PERC 5 Raid card with an onboard battery and 1 Gig of ram so it uses the battery to save the information that was being transfered when the power cuts out and finished it when the PC turns back on.

You do understand that the battery does not power the drives so in the event that you are reading/writting when the power goes out you may experience a damaging head crash anyways? I say may because some drives have a little protection from this type of fault.
