Whats faster?

Recommended Posts

little if any performance increase + bad way to store data = raid0 = bad idea

so raptor is faster :)

If you're copying big files then the increase in STR from RAID will help. Otherwise, if you want a fast drive to load games and the OS, go raptor. There is no answer to your question. Tell us a specific set of uses and we'll tell you which setup is better.

RAM disk. Actually buy a LOT more ram and [insert registry hack here] use more cache. What are you using this for? RAID-0 has some serious problems. Do a serch in the forums to find them. Unless you are streaming Super Ultra Mega Hi-Def Holograms, RAID-0 has no advantages by itself. If you are doing video editing of multiple HD streams, RAID-0 still has no benefits by itself. In the above case, having several RAID-0 scratch volumns may be beneficial, but probably not worth the cost.

If you are looking for the best STR in a single user, single tasking environment (like DOS or something) and have no other concerns, (like streaming a single Super Ultra Mega Hi-Def Hologram) definitly the RAID-0 is the way to go. If you are looking at setting benchmark records for STR, neither will do.

BUT.... if you are doing anything usefull on your boxen, go with the Raptor.

The RAID 0 will have faster STR. The Raptor will have faster seeks. For most desktop uses, including gaming, faster seeks are more important than higher STR.

There's another possibility - two drives, NOT in RAID, used independently, one for OS , apps and games, the other for pagefile and data. This may beat one fast drive like the Raptor, depending on how much RAM you've got, and what you do with your PC. It generally shows more benefit than RAID 0 with the same two drives.

Well, first off, considering you are deciding between a 74GB drive and what would be a 500GB RAID configuration, your real question should be how much storage do you need. I mean, speed will do you nothing if you run out of storage.

You might want to consider cost, too.

A 74GB WD740GD will run you ~USD$2.40/GB

A 500GB RAID of 7K250 will run you ~USD$0.80/GB (including a Promise SATA300 TX4 card)

And finally, you should know that RAID is a four letter word, in every sense, according to StorageReview and its flock. So, you need to consider that, too.

A more interesting comparison, given the relative prices, would be 4 7K250s in RAID 1+0 (stripe across mirrors). With decent RAID controller (or decent s/w RAID) the mirrors should help seek times under heavy read load (two heads available), combined with high STR.

I'd guess the WD740 would still be faster for games (seek intensive and low q depth) but heavier workstation loads might go to 7K250?

Only RAID0 and crappy "software RAID in the BIOS" ATA RAID cards get the four letter word treatment, surely.
