Good or not? raid 0 setup

[Saud]

Hm.. i got one IDE WD800JB 80 gigs 7200 rpm 8 mb cache and i love the hd works 10 better than my last 5400 rpm 14 gigs, i want to buy another one and do raid on my new to come setup DFI UT lanparty mobo i know it compatible

1. Is this harddrive gonna be good? in raid 0 (2) WD800JB?
2. Would this be at least as fast as a 10k rpm rapter or better?
3. Would this be worth the extra 60 bucks w/shipping?

Thank you all

do ide's work in raid?

[dark_15]

yes. but you need a RAID controller card.

[PLtNmHeLiX]

or an onboard controller on the mobo.

dont think they would be faster than a raptor, you should buy some sata drives and use that ide for storage.

[eh?]

1. The harddrive will be fine.
2. Yes. And better.
3. Thats not bad. Are you aware of how raid works? You will only get a total of 80 gigs storage, but it will be much quicker.

on #3, he will have 1 single 160 GB drive from RAID-0. I think you are thinking about RAID 1 there...

thanks guys for anwering my questions

2 80 gig drives in a raid 0 setup wil produce 1 fast 80 gig drive not a 160

all raid does is mirror one drive on to another and then it can read from both drives and essesntially get better bandwidth due to it being able to read from 2 places at once 100mbs x2

Maybe for RAID-1...
For RAID-0 Windows will see one combined drive (2 x 80 = 160)

Remember, RAID-1 mirrors the drive. RAID-0, which is what Saud wants, does a technique called striping to send split the data in half and send one half to each hard drive simultaneously. This gives the user more data thoroughput. However, if one disk dies, you lose all data.

Take a look if you don't believe me

and another site:


What is RAID-0 (striping)?

RAID-0 leverages the read/write capabilities of two or more hard drives working in unison to maximize the storage performance of a computer system. Data in a RAID-0 volume is arranged into blocks that are interleaved among the disks so that reads and writes can be performed in parallel.

This technique, known as "striping", is the fastest of all of the RAID levels, especially for reading and writing large sequential files. Real world usage models where RAID-0 can be of particular benefit include loading large files into an image editing applications, saving large movie files in a video editing application or creating CD or DVD images with a CD/DVD authoring package.

The hard drives in a RAID-0 volume are combined to form one volume which appears as a single virtual drive to the operating system. For example, two 40 GB hard drives in a RAID-0 array will appear as a single 80 GB hard drive to the operating system.

No redundancy information is stored in a RAID-0 volume. This means that if one hard drive fails, all data on both drives is lost... This lack of redundancy is also reflected by the RAID level 0, which indicates no redundancy. RAID-0 is not recommended for use in servers or other environments where data redundancy is a primary goal.

Probably the most important thing to remember is that RAID-0 is nonredundant. Any loss of data, either hardware or in some cases software(a good example is data corruption due to OC), will most likely result in a loss of all data on both disks. Recovery options are bad to nonexistent when this happens. Backups are crucial, unless you do not care about the data.

One other note, a RAID-0 setup may be faster than a Raptor on sustained transfer rate, but can lose significantly in other areas. Seek and disk access times are higher with RAID than those of the higher spindle rate Raptors. True access times also include disk latency and faster spindles have far less latency. Usage patterns can usually determine which would be better for any given application. Typically RAID-0 has the best performance in working with large files, like video and audio editing, while high spindle rate drives are better when working with small files.

ok well it looks like i have been mistaken. oh well. sorry if i confused anyone. so raid 0 is the fastest just back up important things on a second hdd like music and saved vid games. i can deal with a drive craping out.
