How Is Raid Faster? - Page 2

post #11 of 28
RAID0 sacrifices reliability for performance. RAID1 sacrifices performance (though not much) and capacity for reliability. There are other RAID configs that can provide better compromises, but they require more than two drives and a suitable controler.

One thing to remember is that with RAID0 you get full capacity and very impressive performance, but if either drive fails you lose everything on both. For that reason, its quite common to use a pair of small but fast drives in RAID0 for the OS and temporary files, but a single larger, slower drive for important files and documents.

I have noticed that my boot times have gotten longer since my drive gets fuller. So would it be best to just have one small 80GB drive for windows and apps, and then 2 x 250GB for storage and everyfin else?

Other way around I would say... a RAID array for windows, and then a single large drive for storage. Or two RAID arrays

Do you defrag frequently?

Yea I have been a bit lazy on defraging lately. I need to remove some old files off my HDD first that should give me about 50% free. And I will defrag, how often should we defrag?

How often to defrag. THe more you put on and take off the HDDs them more often you should defrag. Once a month is fine for the common usage. If you do masive data work like CAD, Movie editing, photo shoping, etc, more often then.

On the is it faster, in addition to what was covered.
Most programs benifit from RAID0 and some a great deal, games on the other hand only load faster and usually provide very very little or no improvment with gaming.

I was thinking of picking up another Maxtor to put in RAID0 and install Vista on it, or should I go about it a different way?

Raid 1 is also faster than a single drive, because the data can be READ from both, since both contain the exact same data.

I'm planning to go RAID0+1. So far I have 2x Seagate Barrucuda 320GB 720RPM drives, which I originally only intended on using RAID0. Will it matter if the capacity of the other two are different [for RAID1]? Hence RAID0+1?

RAID0+1 requires four identical drives. If you want to build a true RAID0+1 array, current data on your disks will be destroyed (you cannot just 'add' the other two drives to the RAID array). Also, if disks are of different sized, you'll loose any additional space you have on the larger disks (i.e. your 250GB drives will only be recognized as 160GB drives if you add 160BG drives to them).

Given the price difference between 250GB and smaller drives (not a whole lot), I'd add two more of the same drives.

If you only have limited files to back up, you can simply add a third drive, keep it separate, and just make regular back-ups (just get a back-up utility and instruct it to make back-ups every night of new files and files that changed)
