SSD vs HDD for Synology NAS in RAID1
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)..
- 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?
Not sure what the point is of using a SSD in a NAS with only a 1Gbps ethernet port.
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.
I would think you'd be able to get at least a 4TB HDD for the price of a 2TB SSD, and with the right sale, even an 8TB. WD Blue are CMR and while for some reason hard to come by at the moment, run about $100-130 depending on the day.
