Within the last four years, my second of two WD external hard drives (EHDs) has failed; I need to make a smart decision about replacing them. Both EHDs were “My Book Studio for Mac, 2TB.”
Going forward, here’s what I’m looking for. . .
• An EHD for my Time Machine’s backups; need only 2TB capacity
• An EHD for archival storage of thousands of photos; need only 2TB capacity
Because I lost data with both failed EHDs, I want to avoid repeating those catastrophes. I need to maximize the protection of data on both new drives. In effect, I’m interested in learning — once I buy two new My Book 2TBs — how to back up each drive: my backup drive and my storage drive.
To do that, do you recommend that I buy two additional WD My Book EHDs? That’ll be four in total.
- One EHD for Time Machine backups
- One EHD to back up that first drive that holds the Time Machine files
- One EHD to store the photo archive
- And a fourth EHD to back up the photo storage data
Or, should I buy two of WD’s “dual-drive” EHDs? If so, would they be as vulnerable as a single-drive EHD? If one of the dual-drive elements fails, would the paired drive in that machine also be affected by the partner drive’s failure?
I hope that I’ve explained myself clearly and that someone knowledgeable of WD EHDs will provide helpful feedback.
Thanks, in advance.
