SSD on Pro
I am thinking of putting Samsung 840Pro SSDs in my ReadyNas Pro. Yes, I know it's not on the HCL but would like opinion. I currently have 2 512GB hard drives and 2 2TB hard drives. Could I migrate the...
SSDs do SMART (at least the crucial and Samsung drives I've used in laptops do). But some of the usual stats are not reported, or just made up. The crucial reports "flying head writes" which clearly is fabricated.
My main concern is the lack of support for TRIM - which will shorten their life and reduce their performance. There are steps to install TRIM in linux, but they might not work on the pro, given the age of its kernel. (https://wiki.archlinux.org/index.php/So ... rives#TRIM)
Also, I don't see a lot of value in using RAID with SSD. They don't have the same failure mechanisms as hard drives. Sizes also aren't aligned with hard drive sizes. I suspect your 512GB hard drives are actually 500 GB.
If I was going to play with it, I'd do a factory reset and set up the SSDs as jbod. Then use them for small files and databases, where the 0 seek time makes a huge performance difference. And of course back them up.
