Bad Sectors On Two Drives: Unlucky?

MarkeR · 24 Oct 2019 at 10:47

4 bay hp micro gen 8 server running xpenology just for Plex and Emby.
Populated by a 250gig drive and the other 3 bays with 3 2TB drives for storage, no raid setup as the data isnt that important.
Had some bad sectors which caused a volume to crash, so I copied the data over onto another drive with the intention of buyoing a new drive then recopying the data back.
Woke up this morning to find that another drive has failed, the one which the data was being copied to. Unlucky coincidence or something else do you think? File sizes were between 4gig and 10 gig. Transfer rate was good at the time.

Thanks

Always have a good backup.

Similar drives from the same batch run at the same time have similar lifespans? Extra stress from reading/writing a load of data result in death?

Why not use this as a good reason to review the way you have chosen to do things? Firstly a hacked Synology OS is not something you probably want to trust your data to, you shouldn’t have needed to copy your data anywhere. Choose a storage system that actually suits your needs, that can and will be fault tolerant to the level you want. The two main contenders are Unraid (great Docker/VM support) or FreeNAS or one if it’s derivatives (slightly chequered history, choose wisely). Obviously redundancy is not the same as a backup, cloud storage is cheap, unless you have a really slow connection it’s a no brainier for the sort of content you describe and the running costs are a lot less than you’ll pay to buy/power replacement drives over several years.

So probably just blastng the drive with that amount of data killed it?
The data that was stored isn't important, can always get it again, no need for raid and doubling my costs.
If I needed 6TB of cloud storage where would you recommend I get that from?
thanks

RAID in this sort of environment is the last thing you want, something like Unraid where you use a single drive for parity is a much more efficient option. As for cloud storage Google... under £8/m for unlimited, mount either via rclone or Docker.
