yeah raid 0 saves data in stripes across 2 hdds. However you lose the ability to backup from the other disk when one crashes. ie. if one of the two hdds fails, then you stand to lose ALL of your cumulative data of both drives. So carefully consider if the performance is worth the risk. for further reference Standard RAID levels - Wikipedia, the free encyclopedia

Errr... I know all about RAID and stuff. My point is specifically about raptors in RAID.

Often real world performance may not mirror theoretical or benchmarked performance. Hence the query if anyone has used such a setup before :)

I have been doing some research, and people seem to be split between both camps. May just go with only 1 raptor initially.

Anyone who can gimme some inputs?
 
multiply the read/write Performance of Single Raptor to 2...

that's the approx. performance you'll get in RAID 0.

Not really, thats the point. Thats theoretical. While read speeds do increase by ~60%, write speeds may only change by like ~20% from what I have been reading at different places. Which was exactly the reason for my query asking if anyone can gimme some real world data on this :)

Also an Anandtech article I picked up, its old, but hey, those conclusions should still be ok - AnandTech: Western Digital's Raptors in RAID-0: Are two drives better than one?

+ looking at the additional reliability thing, I may just settle for a single raptor for now.
 
it will depend a lot on the raid card ...i get 215mb and 210 in r and w respectively using intel matrix on a seagate 7200.12 (approx 110-115 for r and w) whereas the performance decreases to 80-90 on silicon image 5723

Hmmm... I was thinking of the default mobo RAID option initially.
 
i too tested on default mobo "fake raids" only ...i tested it for the sake of curiosity Intel Matrix Manager vs Sil5723 ...could find any results on the net ...........but the results on intel are so good that u will love it ...data will be copied almost instantly ....
 
Techie, 2 150GB Raptors should set you back by close to 12~13k INR. Why not consider a single 64GB MLC SSD instead? What're the sort of applications you're targeting?
 
I have multiple raptors but the performance of a single drive was pretty good enough so never bothered with setting them up in raid
 
get yourself a velociraptor and be done with it.. you can always add another drive later if you're not happy but I doubt it

What the...whose prices are you quoting please,I'm in the market for one.
 
@Bottle: So 1 it is.

@Arun1: Gannu's pricing is very optimistic :) Rest assured, raptors cost more than that.

EDIT: Approx price updates: 150Gb - 7k, 300Gb - 11.6k

PS: Anyone interested in SSD (Intel 80GB) Vs Raptor argument? This is going to be a system doing a lot of reads AND accessing a MS Access database as well (http://www.techenclave.com/pc-peripherals/components-high-end-data-processing-rig-153733.html), so writes are also involved, hence me leaning towards the Raptor. Wat do you guys think?
 
Prime had quoted 8.9k for the 150gb raptor a week back called them up now to know its not in stock.Called techshop.in who couldn't confirm for the raptor but quoted 8.4k for the velociraptor!

So I guess the raptor could possibly be ~7k.

I have no plans of going raid anytime soon,I'll probably wait a bit and get them velociraptors RARRRR.

Edit:

Was checking out the velociraptor reviews and apparently the new 300Gb raptors have only two 150Gb platters.So does that mean that the new 150Gb ones are single platter or are they still two 75Gb or something else?
 
The intel g2 ssd's have TRIM support right . For me Intel SSD vs Raptor's there is no argument (excluding dough). if you catch my drift :P
 
@Arun1: I am talking Velociraptors only :) The 150Gb is a single platter. 300Gb is a dual platter.

@Shadow: Ya, Intel has TRIM.
 
Guys the raptor 160GB version which carries 1 yr warranty (surprising as they are OEMs which carry no warranty, but the dealer is ready to give 1 yr warranty) is available for 4.5k.
