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)…

  1. wait for RMA SSD to come back and insert 2xSSD (WD Red+ keep aside or try to sell off) + iDrive e2 as remote backup
  2. buy 1 more WD Red+ and insert 2xHDD (2xSSD keep aside or try to sell off) + iDrive e2 as remote backup
  3. 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?
