Replacing Raid 1 HDD's with SSD's - Migration question

post #1 of 4
Thread Starter 
Server Specs
Dell PowerEdge T620
Windows Server 2012 R2
2 x E5 2640 Procs
64 GB RAM
2 x 500GB HDD Raid 1 OS
6 x 2TB HDD Raid 5+1 Storage
Uses: Plex, VPN, BlueIris, Backups, File Sharing

I want to replace the OS HDD's with SSD's. I have 2 x 256GB Samsung SSD's.

Should I use SSD's in Raid 1? I've heard mixed reviews on using them in Raid 1 for a home server due to performance issues.

If I do end up using the SSD's in Raid 1 for the OS what would be the best way to migrate from the existing HDD Raid 1 to SSD Raid 1? Does Samsung Magician offer this capability? Can I just replace 1 HDD and let the array sync and when complete swap the other? Or should I just bite the bullet and re-install WS2012R2 from scratch?

I would recommend reading the differences between all the RAID options some will allow for the rest of the storage to survive a failure while another will fry all storage.

What is the most important thing to you? Performance, Redundancy, etc?

I personally would use raid 1 in the case of a 2 drive setup because I value Redundancy vs performance in that case. If you had 4 or more SSDs I'd say raid 10 if you don't need capacity, raid 6/5 if you do but want some fault tolerance.

You will not have any performance issues running SSDs in a RAID1 array. The speeds will be that of a single SSD which is still going to be far greater than your current HDD. And if your network is only 1Gb that's going to be your bottleneck anyway.

Unfortunately you can not replace the disks in a RAID array with different sized disks. Your only option is to install the Windows Server Backup feature and make a backup to an external source (external drive or network drive). Once you have a backup you can delete the current virtual disk (HDDs) and create a new one (SSDs) and restore the backup.
