im gonna use a 3TB or 4TB hdd for my music and my recorded TV shows from my box with a HDPVR so i dont need a second DVR box etc etc and an SSD for games and a mSATA drive as my boot drive (my motherboard is a g1 sniper 3 by gigabyte with the mSATA connector built in)
question: would be easier to use raid 0 or leave the drives independent drives since they have different purposes
you wouldn't want to use RAID 0 in this set-up. to RAID different drives you would be operating at the speed of the slowest disk, losing any advantage of striping. i would use your SSD to boot from your mSATA for Applications and the large TB drives for bulk storage.
"speed of the slowest disk" - not true. The individual drives retain their individual performance. When a file is spread accross two drives the part of file that is on drive A is accessed and read at the speed of drive A, part on B at B's speed. so overall average is inbetween. But this only applies if the files are larger than 64 Kbs (typical strip size). If the flies are NOT spread on both drives then the file is read at the respected speed of the drive the file is on.
However if two different SIZED drives are used (ie say a 3 TB and a 4 TB) the total size will be 2 x the smallest drive in this case 6 TBs. the extra 1 TB on the second drive is LOST (wasted).
Raid0 for HDDs is only significant when LARGE files that are sequencilly placed are accessed. Raid0 does improve Sequencial performance, but does NOTHING/to VERY LITTLE for small file read/writes, and NOTHING to improve access time.
OP - I'd skip Raid0, Raid0 will not improve watching a video or playing music.
I have a HD DVR which can record two shows at the same time Plus play a 3rd show that had been previouely record - all at the same time. The DVR does not use Raid0. NOTE a Blueray plays fine on a Blu-ray player - And that is SLOWER than molassas compared to a HDD.
HD PVR and Cable box HD DVR both use the same principles.
In the past I've also used a computer to record OTA/Cable TVshows. I used the ATI AIW card - Until Vista killed it. Also Bought My own DVR which had a Woopping 20 Gig HDD, took it apart and put a faster/larger spare computer 120 gig drive in, think you were about 12 then.
You are still at the speed of read/write to a HDD in both systems. All I'm saying is that you should NOT need raid.
In addition to what I said about raid, you should also be aware that NOT all HDDs are recommend for Raid0 - Normally raid0 recommend drives are more expensive - and do NOT inclue the Green, Blu, nor the red with yellow poka-dot drives.
With raid0 if one drive fails you LOOSE ALL data on both drives - can not be easily, if at all, retrieved.
