Which RAID is best for me?

Jake_Green · Jan 12, 2014

So I have 2x 7200 rpm older SATA 2 Hardrives. One is 160GB and the other is 250GB. Both have 8mb of cache. I also have 2x 1TB external drives that I can back my internal drives up on so I'm not concerned with using RAID to protect from hard drive failure. Really what I'm looking to do is give my self the best performance boost that I can get from a RAID application. My mobo supports 0,1, and obviously 10. This will be my first time implementing RAID.

Which version will give me the best performance boost?

Any other advice on RAID is also appreciated.

RAID-0 will give you the best performance.

FYI, the total capacity of a RAID-0 array is based upon the drive in the array with the smallest capacity. So if you RAID-0 a 160GB drive and a 250GB drive then your array's total capacity (before formatting) will be 320GB (160 x 2).

Does the controller support JBOD? That would allow you to use the full capacity of both drives yet span them over 1 large 360GB volume

Yes it supports JBOD. You think that would provide a better performance boost that RAID 0?

JBOD will likely not be as fast as the files will not be evenly spread across both discs however it will be faster than either individual drive over all.

JBoD is only as fast as a single drive.

Raid0's performance increases with the number of drives in the array. Ie- a 4 drive raid0 array is faster than a 2 drive raid0 array. The max speed is determined by the controller though.

While your current best option is to raid0 those two old drives, you'd get even better performance from a modern single drive. Run a benchmark on the 160 and post up a screenshot of it. I'd bet even a WD Red or Green 5400rpm drive is more than twice as fast as it it.

I don't have the desktop yet so I can't get you a benchmark, but it is a Hitachi Deskstar 160GB 7200 rpm hard drive with only 8mb of cache it runs the older SATA II at 3Gbits/s. And my other Hard drive is a Western Digital 250GB 7200rpm with 8mb cache running SATA at 1.5Gbits/s.

I am honestly building the ultimate, lowest budget possible, desktop right now. I have spent a couple of weeks doing extensive research on what the best products for my needs would be and found AMAZING deals on great price/performance products. So I probably will just stick with the hard drives that i have for now until I have some more cash and am ready to upgrade a few things.

This will give you an idea of what I'll be doing.
This is only going to cost me initially $160!!!
(Items I have already)
Windows 7 x64
Apevia X-Jupiter full tower Case w/ a fan controller
Lite On CD/DVD Burner w/ labelflash
7200 rpm 160 and 250 internal hard drives
2x 1TB external hard drives
5x blue LED case fans

(Items I will be buying)
(APU) AMD A6 5400k (39.46 shipped!)
(Mobo) MSI FM2-A75MA-E35 (38.95 shipped!)
(RAM) 2 x 4GB GSkill 1600 Ripjaws (40.00!)
(PSU) Ultra 550LSP ($30)

This first items i would buy after would be first a $25-30 CPU cooler. Then a ~$80 7750 GPU. Then a 500gb-1TB Internal Harddrive. And finally I'd be willing to upgrade my APU to a A10 Richland or the up and coming Kaveri.

Also while we are on the topic of Hard Drives. If i spent $100 on a 120GB Solid State Drive would it significantly improve my performance in games and other applications?

Sorry for the book. I'm a bit of a writer. haha
