Ok recently I have been working on backing up my 17″ Mac Book Pro OS X machine (10.5). I am pretty good about backups… but not offsite backups, which would survive theft or server crash or house burning down.
I’ve become even more superstitious of late, because of what I’ve done to my Mac Book Pro – installing a striped RAID of two 500GB hard drives.
Yep, you read it right, I have almost a 1TB disk. How? I bought two nominally 500GB hard drives (amusingly, each enclosure contained a different manufacturer – one hitachi and one samsung).
Then I purchased an adapter from MCE Tech, which has the same internal shape as my MBP’s DVD drive, but adapts the DVD ATA connection to take a SATA hard drive:
I ordered the external DVD enclosure for $50 as well, but I’m going to return it, because it has no faceplate and is ugly.
Instead, I’m probably going to buy a Mac Book Air Superdrive and hack it.
A smart thing to do would have been either:
1) Make a RAID mirror of the two drives. I would only have 500GB of storage total, but my chance of data loss would be far less with a backup drive.
2) Leave the drives separate. I’d have 500GB + 500GB, and I could even back up critical data using Time Machine.
Of course I did the cooler, more risky thing: I used a RAID stripe – half the data to each drive, adding the drives together.
If either drive goes, I lose all my data.
This is why I need better backups now.
