Raid 0 or 10,000 RPM drive?

post #1 of 26
Thread Starter 
I was looking to either add a second WD 250GB 16MB Cache hardrive to run raid 0 or buy a Western Digital Raptor. Which choice would be the more logical for ugraded performance? The 250GB drive would cost me around $90 and the raptor would cost me $190

Add the second drive. Best is one with identical specs.

The RAID0 set up will actually have a higher data throughput (bandwidth) than the single Raptor. Obviously, you'll have more storage space. The only thing the Raptor is the winner is access times.

best of both worlds.... 2 Raptors in RAID 0

naw, get the identical drive to what you have... it's a better price/performance ratio

ditto, if you were buying all new and had loads of $$ to blow I would say get raptors, but since you already have a large drive, just get another one one.

Single Raptor. Two drives in RAID 0 isn't any faster for data access or loading, which is what's important. RAID 0 is pretty much useless unless you do a LOT of writing to your hard drives (like if you do video editing).

There's a lot of misconception about what RAID 0 is and what it isn't. What it isn't is useful for desktop users / gamers.

But you still get better performance, and a ton more storage space. Hell, buy two more 250 gigs, it'll still cost less than the raptor.

Performance isn't necessarily better.

Quote:
In regards to the specific question of whether a pair of drives in RAID 0 can degrade performance as compared to a single identical drive, other than the unlikely CPU example above the answer is "probably not." Some may say that access time can be increased (worse) due to a specific read (or write) requiring both heads to seek to their portion of the data, creating the result that average access time will be slower. However, this only really applies when accessing large numbers of small files as larger files will benefit from the improved STR. Unless the configured stripe size is too small, most of the small reads will access only one drive.
I encourage the OP to read the storage review FAQ I posted to decide whether RAID 0 will actually be beneficial. Like I said, it really isn't a good idea unless you do stuff like video or audio editing. If you get the second 250GB drive, it might be more advantageous to run it as an independent drive rather than in RAID.

Buy 3 more for 1TB of space, and super RAID-0.
