hi guys well i need little help with making raid disk well i have two disks and i would one of them put to raid so would that be good and how fast would raid work data read cache and rest any benchmark info would be nice to see
I'm assuming you're looking to set RAID0 which provides increased performance without any fault tolerance. The gamer's choice. You ought to be using two identical "freshly purchased" new disks. Why? Well they should be Identical so you get to use all your capacity. New disks so you aren't putting the array at risk when one drive fails prematurely. Lots of motherboards today support raid but if yours doesn't do hardware raid you'll have lower performance and higher cpu usage. In that case consider a good quality raid controller. Burst read speeds are increased along the lines of 50% and average transfer rates will be roughly doubled which is really nice. Games that read a lot from the HDD such as oblivion, stalker will be a lot smoother (ingame) whiler others will generally (cpu permitting) load faster. Some benchmarks show no gains for loading times simply because the rest of the system can't keep up. With a reasonably powerful rig you'll se gains accross the board. When doing Raid0 your hard drives are identified as a single large hard disk. All degragmentation applications (including windows' built it defrag) can properly defragment raid0 arrays. Not only do they defrag faster but the results will also be excellent so while regular defragmentation will help you get the most out of any hard drive this is specially true for raid0 arrays! When setting up a raid0 array you need to pick the right striping. If you do a lot of work with small files then the striping should be smaller too such as 16KB or even less. However I'm going to take a calculated guess that you'll be wanting to work with larger files such as videos, game data files etc, in that case pick a large striping setting. I hope I have been of some help (and hopefully accurate too).
one more question dose mirror disk raid works good ? well you know that it is on one disk but with two partitions
Can you actually do that??? AFAIK, even if it's possible to do RAID on a single hard drive, there's no benefit at all. In fact, its performance should be worse than just using a single drive.
BTW, Mirror RAID is only good for data redundancy. Unless you do stripping, its performance should be similar to that of a single drive, maybe slightly slower.
Good for backup I guess. I hate mirroring because I'd be wasting 1 HDD. But when things go wrong, you'll hate yourself when you never backup.
That's why I do manual backup, or just use a third party software to copy important files to the backup HDD. No need for RAID 1.
Certain programs can take advantage of the mirroring in RAID1 for a performance boost, but that's really rare.
