long story short...
- hosted 2x2TB Crucial MX500 SSD in RAID1 in DNS-320L (Dlink)
- both metadata and superblock corrupted, unable to boot.
- spent $1.5k for data recovery and sent 1 of the SSD for RMA (bad sectors)
- bought new NAS 223j and 1x WD Red Plus 2TB
- insert WD Red+ and MX500 SSD cannot create SHR storage pool (because HDD and SSD cannot mix)
my solutions (3-2-1 backup strategy)..
- wait for RMA SSD to come back and insert 2xSSD (WD Red+ keep aside or try to sell off) + iDrive e2 as remote backup
- buy 1 more WD Red+ and insert 2xHDD (2xSSD keep aside or try to sell off) + iDrive e2 as remote backup
- ignore the 3-2-1 remote backup strategy: buy 1 more WD Red+ and insert 2xHDD to start using NAS + buy SSD enclosure to use 1 of the 2 SSD as 2nd backup (via NAS USB port) .. NOT paying for iDrive e2 subscription.
What will you do in my case?
i went ahead and setup 2x2tb wd red+ as raid1 in shr1 in synology 2bay 223j,but i still have commenters said i should deploy 2x SSD instead, for cache and indexing, i dont quite undetstand what benefits i can get from using SSD vs HDD.
