what raid i should use for full space and most speed??

post #1 of 7
Thread Starter 
ok so, ive got 2x30gb Kingston SSDNow V Series that runs at:

Read up to 180MB/s
Write up to 50MB/s

and i have 1x64gb ADATA SSD that runs at:

Read Speed Up to 280MBps
Write Speed Up to 270MBps


im currently running Raid 0 and made 2 drives of 58gb from 3 SSD's!!! (total 116gb)

now after awhile i decided to make 1 drive out of 3 so i can have one drive of 116gb instead of 2 separate 58gb. which Raid i can use since i have 3 drives that are in different sizes and not lose any space?! also does my speed lowers when i combine these 3 SSD's??


Thanks

Not losing any space = RAID 0, or JBOD which really isn't a RAID mode.
Kind of a misnomer since there is no Redundancy.

Every other mode will require you to sacrifice drive space at the cost of reliability/recoverability.

An onboard 'fake'RAID probably won't let you RAID 0 the 30 GB's together and then collectively stripe with the (effectively) 60 GB drive.

thanks for the reply but how can i raid 30's together and then add it to 64gb? is that even possible?

You could do 2xRAID0 SSDNow using the host-based controller.... then 2xRAID0 of that array and the ADATA with software-based array.

However, I would never do that. While your sequential performance goes up, your random performance goes down.... and random is more important. Plus the complexity and data loss risk....

thats very interesting.....ive never thought i could do that!...ok so imagine im gonna raid the 30gb's and then install windows on it! am i still gonna be able to add the 64gb to them and make a C: drive?

the software based raid is via windows right?so you wont be able to access your files unless you are in windows right??

No, can't be C: drive....

Again... don't do it..... it's not worth it.
