Want help with RAID?

post #1 of 4
Thread Starter 
I have 2 hard drives.one is 160GB and other is 500GB.
Firstly,i want to know should i use them independently or in RAID setup.I am confused little bit that in RAID i will not be able to utilize full space(160+500) of my hard drives and is RAID little bit slower.
Please also tell me about advantages and disadvantages of both of above methods.
I want to utilize all of my space.
Also tell me about AHCI.Is it more useful than above.
Please help me.

With such unequal drives there are really no advantages to going with a raid setup. - If you had equal, or even close to equal drives the advantages would be numerous depending on which raid level you have setup. Raid-0 would offer speed advantages by writing to both drives at the same time (known as striping) there by effectively doubling the speed of a standard hard drive (not quite, but close to double the speed in reads and writes) - though if one drive fails then you lose all data. If you set up with Raid-1 you would have the advantage of redundancy, if one drive fails, the exact information is already written on the other drive there by providing security in case of failure.

I am by far not an expert on AHCI mode, I do utilize it and know that it does offer advantages over IDE mode. I would refer you to an article such as : https://expertester.wordpress.com/20...ark-advantage/

Hope this helps answer all your questions! Good luck

Smallest drive determines the size of the array (size of smallest drive x total number of drives).

In your case you would end up with a 320GB array using RAID0 or a 160GB array using RAID1. Either way you are losing ~340GB of capacity from the 500GB drive.

My suggestion would be to spring for another 160GB or 500GB drive (preferably same manufacturer and model number as the one you own already) if you want to dabble in RAID.
At long last...

Thanks for suggestion,i will not try RAID rather AHCI.
