RAID 0 with raptors or New hardrives?

[Dethman55]

Currently I have 2 of the older Raptors, their 8mb cache, 10,000 rpm, 36 gig, SATA 1.5 hard drives in raid 0....I have a backup/storage drive that is a 8mb cache, 72,000 rpm 120gig drive

I am currently running out of space on both, so im looking to get like a 500, or 750 gig drive

Here is my question, in relating to speed for gaming, and just general quickness/speed...would it be better to get a new hard drive for storage, and keep the OS install on the raptors...or should i just sell the 2 raptors, and get a 32mb cache, 72,000rpm, SATA 3.0 750mb hard drive, and put my OS install on that?

Would there be a noticeable difference?, if so, by about how much?....If not much, i would rather sell the raptors, and put that towards the larger hard drive purchase

Newer Sata drives will have similar read and write or possibly better than the raptors. But even the older Raptors access times still beat the newer SATA drives access times by about 2.

this leads me to a question actually...on my new build i am going to have 2 drives in raid 0 for the performance aspect

i've heard the larger the drive the higher the failure rate, how true is this? i'd like to put two 1 TB drives in raid, but if that will have a high failure rate then what would be the best size drives to get

 

[mooseracing]

What failure rate is acceptable to you though?

I don't know the actual failure rates of RAID but it may not be acceptable for a corporate that wants 99.9% uptime. Not that many run RAID 0, usually RAID 10 if they wanted that extra perf.


edit: I'll add more info to this tonight on the raptor benchmarks as I am going to add a couple new 250's to a RAID 0 setup to see how it beats my raptor, i might even do 4 drive RAID 0 depending on how things look.

that would be cool,
If my raptors in raid0 are much faster than just one new drive.....than its not worth the upgrade to me...but if its close, i could use some more space

If you want to buy some new drives, how about a single VelociRaptor for the boot/game drive to get both low access times (even better than old Raptors), more space and higher transfer rates? Then, maybe some cheap 750GB drive for just data storage.

Lots of good advice above:

We have 2 Raptors hosting the C: system partitions for XP/Pro x32:
both were excellent investments, overall.

Here are my 2 cents, FWIW:

There are three (3) relatively recent versions of the VelociRaptor:

(1) the IcePak was re-designed with SATA power and signal connectors
that mate with industry-standard backplanes;

(2) the IcePak was removed for the "enterprise-class" 2.5" form factor,
and this one also comes in 300GB capacity;

(3) same as (2) but only 150GB capacity.

Because any good case will have a drive cage with integrated fan,
a 2.5-to-3.5" adapter will permit (3) above to fit into any standard
drive cage, with room to spare and lots of air flow around it.

You may need to order a 150GB VelociRaptor in 2.5" form factor
directly from Western Digital, but I think this is an excellent
"future-proof" investment for your C: system partition.

As for storage, I'm always recommending 2 x 500GB SATA/3G in RAID 0:
just as it is with a single HDD, if one of those 2 in RAID 0 should fail,
yes you lose all your data, and you still need to replace the failed drive:
both of those are true of a single HDD too, so it's a wash, imho.

And, prices on 500GB SATA/3G HDDs are really good right now.

You'll get better performance from 2 x SATA/3G HDDs in RAID 0, overall,
than a single SATA/3G.

Think parallelism: we have multi-core CPUs now, and dual-channel memory
soon to become triple-channel memory with the Intel Nehalem architecture.

Why shouldn't storage systems also have multiple channels? Duuh!
