I have a Western Digital WD Black WD2002FAEX 2TB, now every once in a while during boot that sucker will get really effin loud and it sounds like its spinning fast. Luckily I don't have a ton of precious data on there, I mean there are pictures but not a crap load that I can't put on my old 500gb WD black.
I'm thinking of buying another Western Digital WD Black WD2002FAEX 2TB and mirroring them in RAID 1; because I do want to start puting more media on my current drive. My question is would that be more cost-efficient or would it be more cost-efficient to make images of all the data I really care about and just burn them to re writable bluray disks, and just copy over when need be?
Thanks in ahead
Edit: It should be noted that I boot from a Samsung 830 256gb SSD; so I'd like to back that up too but its not at the top of my list(I don't even use 70gbs of it..mainly because I don't game anymore and deleted them all)
There's a "short" and "long" test (may be called "extended" I can't recall). Use the long test to be really sure there's nothing wrong with the drive.
For backing up your data I would not create backup images. Just copy the data to a pair of external hard drives so the files can be retrieved easily without need for using proprietary recovery software. You can write the data to blu-ray if you'd prefer, but my own preference is to use external hard drives (four of them, in fact, so I have three backups if one should fail.
Creating a partition-image is something I do only to back up my OS drive.
Have you considered using a cloud service for your backup needs? From the sound of it you do not have a lot of data you want to back up. I would recommend using google drive or skydrive as they are free services and give you a great backup option.
