Hey all i have one of these Western Digital Caviar RE 160GB 1600YS SATA-II 16MB Cache - OEM

Would it be better/faster to buy two more so i have three in total and have 3 of these baby's in raid 0?

is that possible to have 3 in raid 0?

 

[born2killU]

yeah but it wouldnt be much faster than having two in raid0

Just buy another or another 3 to run raid 10 or 1+0 whatever

The way I understand it is you can have as many harddrives in raid0 as your raid controller supports.

you will have to reformat

Get two more. Do RAID 0+1.

 

[MrBungle]

okay, so your answer is yes. i'm not a RAID guru, but i believe it doubles your throughput but has no effect on your seek time.

i play CoD2 with a friend of mine that has a Raptor. i have two 7200 RPM drives in RAID-0 and i am always the first person in when a new map loads. my buddy with the Raptor is pissed because he used to always be the first, now it's me. for price/performance, i'd pick 7,200 RPM RAID over 10,000 RPM without.

Yup , listen to us and you will be happy , and if a drive or two fail you will be good

 

[MrBungle]

i love how all these people with 1 hard drive are so happy to spend your money for you

are we really that worried about hard drive failure? i have RAID-0 and sleep like a baby at night. i realize that i have now tempted fate by saying this and one of my drives will surely fail while i sleep tonight, but come on. they're pretty realiable. i'd bet money my CPU fan will fail before either of my HDDs do. i'd also bet money that i have a new computer before any of those things fail.

Don't you need an even number of drives for Raid 0+1?

I have 2, I agree with them. Get another drive and run a RAID 0+1.

If I were to use 0+1 would I have to get a RAID controller?

RTFM!

Performance increases linearly as far as I know. 3 in RAID 0 are 3 times faster than one drive (apart from the SATA raid controller overhead that decreases the speed a bit). RAID 0+1 is for who cares about 100% data integrity WITHOUT doing backups. On my home PC I have games, pictures and music, all of them backed up on DVDs. If my HDD fails, I'll be upset, but in the end all that I have to do is to reinstall WIN on another HDD, and that's it. RAID 0+1 - no way.

I've seen you have a WD 160 GB, and I'm searching for a silent 160GB HDD to RAID 0. How is yours doing while searching? Is it above or below the ambient noise?

Cheers!

Diminishing returns... Generically and assuming a good controller
1 HD = 100%
2 HDs = 180%
3 HDs = 220%
4 HDs = 260%

There will always be an overheard of transferring the data, buffering, etc. RAID0 just reduces the time waiting for the head finding a sector. It only helps with one part of the process of reading/writing data.

I know it supports RAID 0+1, but I was wondering if it is similar to RAID5. I would definitely not use RAID5 without a controller, but I'm wondering if this is also supposed to be the case for RAID 0+1.

And is the performance between RAID0 and 0+1 pretty similar?

How is he supposed to do RAID0+1 with 3 drives?

Where is this information from? It sounds about right based upon the fact that my 4 HDDs give me 210% performance on the southbridge, but it would be nice to know where you got that from.

Made the numbers up to illustrate a point! They are guesstimates.

Isn't that backwards? RAID0 does not decrease seek time (which is what I'm assuming you mean by finding a sector), but it increases the speed at which data can be read/written. Correct me if I am wrong...
