74 GB Raptors vs. 160 GB Caviars

I'm just curious what the difference is between these. The Raptors are Serial ATA150 @ 10,000 RPM's but the Caviar is SATA II 3 GB/s. The prices of Raptors are clearly much higher than that of the Caviar. My question is why do people buy Raptors (I know they're fast but is it worth the money?) and what do people use them for in RAID 0. Wouldn't the 3GB/s on the Caviar be fast enough?

The raptor's higher RPM allows for higher read/write rates, also it will have lower access time. Most users will not see much of a difference in performance, windows may load a few seconds faster, and game levels may load quicker as well. The real benefit comes when large amounts of data are read and written to the harddrive, such as digital video editing. This type of activity will show a larger improvement in speed than most everyday applications.

 

As for having things in RAID0, it in theory doubles the read/write speed of your drives, and this will have an added bonus on top of having faster drives.

 

Note that this is simply my interpretation of what I've read and seen.

check out the HDD benchmarking thread here http://www.dfi-street.com/forum/showthread.php?t=4177

 

there is a ton of comparisons between sata2 raid0 arrays and raptor arrays, as well as single disks. if you look, you will also see discussion about real world speed for different applications.

Raptors are mega expensive dollar per GB. If you have money to burn, want a chest pounding sig the raptors rule!

 

I didnt notice a difference going from a 36GB raptor to WD 80GB sata, in my nF3 setup
