"Raid 50" idea help and opinions

post #1 of 3
Thread Starter 
Hi guys so I have a ''home server" running on W8.1. Is mostly used for backing up all the computers in the house and streaming media to Tv and devices using plex. It currently have a raid 5 of 3 4TB WD reds and a intel ssd for the OS. I was planning on adding 3 more 4TB drives and putting them together in a raid 50. The plan that I have right know is to make 2 raid 5 volumes and use windows storage spaces to raid 0 them. And now the question is will this work right? I know I should get a dedicated raid card for this but I love that currently this system only consume 32Watts and I have seen raid card using 10 to 15W because of their built in CPU. So should I give it a try on the storage spaces or should I go and buy an used LSI raid card??

From my point of view it's total madness to RAID 6x 4TB drives in RAID50 - doesn't matter as a one volume or 2xR5 with stripping. Potential failure rate is very high and only 1 drive may go bad. Rebuild time will take hours if not days. With 6 drives the only logical choice is RAID 6 or with 8 RAID10. My personal preference of drives is HGST NAS, but that's open to debate.

If you want to avoid buying RAID controller and stay with WD Reds then the only way forward for you is trying drive pool (like StableBit for example). You gain tons of redundancy - normal RAID offers at most 2 disk failures, with pool you can raise that bar significantly. And you can use even cheapest disks around. Expanding/downsizing pool is trivial just plug disk click add or click remove on existing drive and voila. Pool will take of the rest. For example SB Drive Pool is vastly superior to Storage Spaces. It's a non-contest from the word go. Period. Don't need paired drives like RAID for optimal operation. Also SB DP works very well with external USB3 enclosures. I have 2x 8xbay JBODs standing next to me. Working like charm. With optional (free) plug-in you can add SSD caching, so you won't have to deal with spinning drives speeds when reading/writing from/to the pool. In one sentence DP is great way to utilize all these old disks lying around. smile.gif

Given the info you provided - [Stable Bit] Drive Pool is my choice. Simplicity and power in one small package.
