M.2 For Boot 2 SSD's Raid

EminiTrader · Oct 26, 2016

Hi Guys-

I am doing my first build in many years and I have a question about storage/RAID. I am doing using the i7-6700k with the Asus z170 Deluxe. I have a Samsung 950 m.2 that I will use as my boot/windows drive.

I want to set up 2 SSD's for storage but set them up as RAID 1 as I do a ton of videos and I need a backup. I don't need my Windows drive (Samsung 950) to be on RAID.

I've setup RAID before but not with 2 independent drives and not including the boot drive. Is this easy to accomplish with the Asus UEFI ?

I've found many of videos and articles online (even here) that show how to setup 2 drives for RAID 1 using the Windows drive but not 2 independent drives.

I appreciate any input!

Thanks
-David

doing a RAID 1 on SSD's is pointless. they will both have the same wear and tear and fail close to each other if they do fail from wear and tear.

now failing from other defects it will help with but most people say don't do RAID 1 on SSD's. Also TRIM is only supported on Intel controlers in RAID 0 but the internal Garbage Collection should be enough to not have the drives lose their write endurance though.

Now as far as setting up RAID. You have to select RAID over AHCI in the BIOS. Once that is set there should be either options in the BIOS or right after the POST screen to enter a RAID BIOS. From there you can then setup a RAID 1 of your SSD's.

Hi DrTweak - thanks for the reply. I hadn't thought about the wear and tear being the same on SSD's... My biggest concern of course is data loss but I have been doing some reading and you pretty much confirmed what I've read earlier today... Definitely have to think this through a bit more.

I say get an SSD for live data, then have a larger HDD for data dumps. You can use a program like Unstoppable Copier to just do a copy of your SSD to HDD and it can skip files that are already on there then just setup a time using the Task Schedualer in windows. I have a few clients setup that way for Archive backups. They have had issues with files being deleted and months later realizing it and by then it has been over written in the backups so i setup their old NAS backup to just be an archive and every hour it just copies everything that is new over. it doesn't keep multiple backups because it will just over write the old file but at least if a file is ever delete it will be there since it is only filling space with new files.

DrTweak - thanks again! I did not know about Unstoppable Copier. I have a a 1TB WD that is in my current machine that I believe I'll move over to the new one. I'm gonna back that one up first as I am concerned that a new install of Windows on a new machine may not recognize that hard-disk without formatting... This is where my experience level drops to zero
