Setting up Raid 1 -Two 160GB drives but with different cache

[h2oman]

Can someone tell me if I will have any issues stting up Raid 1 if one of my drives has an 8 MB cache and the other has a 16 MB cache? Thanks

Anyone? Will cache make a difference?

Nope, you shouldn't have any issues.

I had a 2mb cache and an 8mb cache drive in RAID-0, never had any problems.

I think the cache's are just added together and managed by whatever RAID controller is controlling it.

Thanks, I'm doing another build so I ordered another 16MB cache just in case. But I'll give the 8 and 16 a try first.

Nope, the caches are not added together that way unfortunately, for all intents and purposes it will only use 8meg on each drive. The difference between 8 and 16 isn't that significant to warrant a new drive purchase so I wouldn't bother. For an example, my raid controller has 128megs of cache and if I disable it i don't notice much of a difference under normal usage.


Long story short, you're just fine with an 8 and a 16

Though if your data is important I'd reccomend doing a RAID 0 on the two 16's and using the 8 as a backup. I know I tend to over-stress this in my posts but I've lost a lot of data, remember if either drive fails all data is lost, if the board/controller dies all data is most likely lost depending on the situation, drives fall out of arrays etc.
