How good is RAID

[mikysee]

Would two 20gig 5400rpm ata66 in a RAID setup beat my ibm 45gig deskstar? I'm think of trading it.

The short answer is no. The long answer is, in rare occasions yes.

Software RAID: BAD
Hardware RAID: Good, depending on what your doing.

If you need redundancy and fault tolerance then RAID is excellent. If you need read/write trabsfer rates then RAID can be a dream come true or a nightmare depending on how it's configured and what RAID level your using.

IMHO RAID involves too much overhead to make it worth in for home systems though.

If you went with 2 IBM Deskstars then you would see a performance increase. You have probably the best IDE hard drive in the world right now, why would you want to trade it? Just buy another one.

 

[Sugadaddy]

keep your 75gxp. That RAID setup will be about the same speed in transfer rates, but will have very bad seek times, making it slower than your single drive.

What about two 20gig 7200rpm ata66 drives?

 

[Pariah]

In a 2 drive array, there isn't much of a difference between software and hardware RAID. As you add drives the performance gap increases. RAID does not increase access time, it actually artificially lowers it a bit. Even so, RAID is pretty useless for the vast majority of home users, and not worth the effort.

Depends on what you want it to do. As stated before, access time will take a hit, but read/write time as well as redundancy can pick up dramatically with RAID.

don't sell it but if you do email me

I have 2 5400rpm 15 gig hard drives in raid0 and they work great! They are way better than my old 20 gig Maxtor.
