Hi guys,

I'm new to the forum and I couldn't find anything specific on my question, so sorry in advance if it has already been discussed. I am thinking about running a 512GB M.2 SATA III SSD with a 128GB half-height mSATA SATA III SSD in RAID 0. I dont know much about RAID, so my first question is will RAID 0 work with two SSDs of differing capacities? Second, will I see a performance increase? The 512GB is rated at a max read/write (MB/s) of 550/500 and the 128GB at 500/200.

I know this is off topic of the thread, but what are the real world benefits of 4GB vs 8GB vs 12GB of RAM.

Any responses are much appreciated.

You may use disks of differing capacities if and only if the raid controller supports Matrix RAID. Fortunately, Intel's firmware raid controller does support this. You will be able to divide the larger disk into a 128GB volume and a 384GB volume, you can then place the 128GB volume in RAID0 with your 128GB SSD.

As for performance gains, there are almost none to be had with SSD RAIDs.

I recommend against utilizing RAID on 99% of home builds - the cost to benefit ratio and the potential problems inherent with RAID make it more of a headache than any benefit. I build RAID systems at work....and of the 5 computers I have at home - none have RAID.

The biggest issue with RAID 0 is if either drive fails - you lose 100% of your data. Since you have two drives - you double your chances for failure.

You will not see any appreciable increase in performance that you will be able to see (if something takes 5 second to load in a non-RAID setup, it may load in 4.8 second in RAID. Boot times of 8 seconds would be 7.75 seconds....

On the RAM - 8GB is the minimum I recommend for home computers....I do not recommend going to 12 or 16GB unless you are running programs that will take advantage of it - and the list is usually high-end software like Adobe Photoshop CS6 and higher, CAD programs, Scientific programs, SQL Server, etc.....Gaming's sweet spot today is 8GB.
