SSD vs HDD for Synology NAS in RAID1

  • 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.

    just offload photos from mobile storage to nas every 3 weeks, plus occasionally steam drama series from nas via dlna or plex.

    SSD vs HDD for Synology NAS in RAID1

  • if i remembered correctly, the crucial mx500 had a same price point vs a HDD for 2TB hence i went ahead to purchase SSD use for NAS.

    SSD vs HDD for Synology NAS in RAID1

    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?
