how to use RAID function

[akunih]

---

using raid why not? but consider this RAID or mirrored drive only supports Windows 2000/2003 server and other server based os i.e sun solaris, oracle etcs..

@akunih : bro dili man guro ingon ana ang case na server os ra mo dagan ang raid
kay sa ako-a 80G SATA x2 @ Raid 0 man ang ako setup ako os kay xp pro sp2

RAID 0- you need to identical HDS to work properely and efficiently.
RAID 1- you need to identical HDS to work properely and effeciently.

RAID 0+1- You need 4(FOUR) identical HDS to work properely and effeciently.


Built in Raid is ok. Like Fatsu im using 2x80 Seagate Satas.


How Raid 0 works:
It rights on the first available space on the first HD then seeks for the next available space to write to, while it is doing so (seek time) it rights and available space already ready on the second HD and vice versa. Basically you are reducing "seek time"

How raid 1 works:
It basically duplilcates 1 HD to another. If you are on raid 0 then two HDs are treated as one so, you have to have two HDs on raid 0 as well for them data to be backed up to.

Here are some benchies:
single sata no raid = 100-110mbps
Dual sata on raid 0= 200-220mps thats double the speed.

Dual Sata on Raid Actual:

Single Pata


Wala koy screenshot sa Single sata will try to get later

^^isnt it 3 disks okay na?

I have 2x160GB RAID 0 with insufficient PSU and got myself a 4kb bad sector....hehehehe

anong 160gb yan? IDE or SATA?

I'm interested in the the performance gain sa raid so I guess it means raid 0. I would guess that it is the boot disk working 2 disk as one. How about other drives, do they have to be raid also?
For example, my HD configuration is primary master -40gb barracuda (my OS drive), primary slave - 120 barracuda (data), secondary master - 120 barracuda (data), secondary slave 16xDVD dual layer. I just got an asrock 939 NF4G - SATA 2 wit ha 3200+. I haven't used the SATA yet since these HDs are leftover from a previous system. If I was to achieve the same situation with speed gains, does that mean I need 6 HDs to get the results? Should all of them be SATA drives or can some be IDE? My work is primarily audio production - re - midi sequencing, audio recording/mixing and a little bit of video. My experience has always been to have 1 OS hd for apps only - with no data, and the rest, data HDs and cdrom. The nature of audio programs is that by default it uses more the HD where your data is stored that is why ever since I started audio with win95, I have always separated data from where the apps are installed. I still don't want my data in the same HD as my apps so does that mean my data HDs should also be raid as my OS drive would be in order to get the performance edge. In days past I would have to move my data from the data drive to the scsi OS drive to get the right performance but when the P4/athlon processors came, I found it unneccessary to do so and just worked within the data drive.
Can I do a raid only on the data disc and not on the OS?
I am not so much concerned with loss of data as I backup each project to DVDrom all the time everytime I am finished. But the performance gains do intrigue me as I am using more and more tracks including virtual samples and instruments and more plugins. The faster the computer system, the tendency to use more and more tracks and plugins!!!!
Man so many questions to ask!!!
What do you guys think about this?

i'll try to answer a few...

- if you will be making a RAID config it should be 2 identical HD, same size, same model, same RPM
- you can also make a PATA(IDE) or the older versions of HD's into a raid config
- yes, you can also make a raid config for data disk only. however its better to make the sys disk as the one in raid bec it is where most of the read and write in the system occurs.

so pwede to raid the system disk via sata then have 2 other raid system whether ide or sata for the data? or just one raid system for the os then data drives ordinary lang?
However in audio it is usually the drive that contains data that is most read/written, and it would be logical to have processes and plugins along with the apps drive while your data and samples/soft synths in another. In that case it's probably to raid the data disk too di ba?
Thats a lot of hard disks man, six for my current config.!!
