I think most of us on this forum probably have suffered a crash or two, given the large amount of audio and video we consume.
I had two crashes myself - one Seagate and one WD
One of them I was able to recover fairly cheaply - the other one was impossible to recover.
After my second HDD crash, I started looking for options of avoiding a repeat.
The hardware RAID option was the first thing that came to mind. However reading up on it wasnt very reassuring. Mainly the fact that the data is saved spread across multiple disks. Hence the data is only readable via the RAID array. You cannot pull out a drive and connect it to a different computer and find readable data.
Then I came across software backup options. And Flexraid (
Data Protection & Recovery | FlexRAID) stood out. It maintains parity data on a separate drive and the other data drives are normal windows drives. Meaning they are accessible with or without flexraid. It is not real time like RAID but for media files, backing up once a day or once a week is more than enough.
[edit : now that I read it, it sounds like a Flexraid advertisement. So just announcing - I am in no way related to Flexraid. Just a supremely satisfied customer]
My current file server has 3 data drives and 1 parity drive. It has been about 2 years now. I have suffered one 2TB drive crash. Shipped off the defective drive to WD. Replacement arrived in a week. Put drive back in and overnight all the data was restored.
Now I am much more relaxed - knowing the system can handle one disk crash. And the software cost just $38 for a lifetime license
IMO, make a point to keep backups of your collection and remember RAID is not a backup.
It is possible to make backups of important stuff like financials/work files/sentimental pictures etc. But is it always possible to back up audio video collection ? I have media spread over 3+2+2 TB. Backing it up with identical disks is possible but ridiculously expensive
