Raid (Which to use, How to)

post #1 of 22
Thread Starter 
Well, I have 2 same WD drives, how big of an improvement will I see if I do raid 0? I have both of them filled with data, is there any way I could do this without formating? Is there any site that I could upload all the data on, and then download them? What is the best choice of raid for me if I want maximum storage? I already read the raid Faq so dont post that.

You have 2 drives, so only RAID0 and RAID1 are options. Since you want performance increase and max. storage space, RAID0 is your choice.

The improvement is usually significant, but more noticable in large file transfers than in small files. I'd say my guestimate is about 25%-30% increase on average

There is no way to create a RAID array without losing all data. Thus, a backup should be made. I don't know about any websites that are able to store GB's of data. I would recommend to get a DVD burner and burn the data to DVD's. DVD burners are currently in the $40-$50 range, and I expect that you have to pay for a website that can store GB's... It's a good idea to have a backup medium anyways. (not to mention bandwith.. even with fast internet, uploading GB's will take a long time; upload is normally much slower than download).

Final note, realize that RAID0 will increase risk in case of disk failure. However, I like the improved speeds myself.

This website has a little more info on RAID:

Well my I have a 3mb upload, so I am fine. And I would need like 50+ dvd's, that would take ages to burn. Maybie I will wait for blue-ray, or hd-dvd. If I bought one more of those drives, could I do it with out loosing data? I also have a full 300gb external maxtor, if that changes something.

chozart is correct on most of the stuff but i would say that RAID 0 will only give u an increase of performance in terms of 5-7% more or less. too insignificant to notice unless u r doing big time read write tasks which under normal circumstances doesnt happen. doing RAID 1 is only for data security any provides no performance increase rather u might notice a drop.

so there is pretty much no reason for me to do raid?

like i said not unless u wanna do it for fun or really require the data security for RAID 1. u can see that I did RAID 0 which was because i thought i would see some improvement there but then on sata drives u r not gonna see much of anything. talk about a 10000RPM drive or a SCSI drive, then u r in a league completely though.

The increase of performance depends on your usage, I agree. However, 5-7% seems a bit low imo, and contrary to my practical experience. My estimate might be a bit too high, but in practice the difference is notacible.

I did choose for RAID0, since I could start from scratch. In your position, however, the effort seems too much to justify the goal.

Again, building ANY raid array will destroy ALL data on the drives involved.
Also, 50+ DVD's ... that's like 200GB??? At 3MB that will take you ~20 hours?

200GB storage space costs $400 / month! Yikes

Yes its not worth going through all the hassle and backing up all the files on your HDDs. Waiting for a Blu-Ray disk and driver will cost over $100, so that is IMO not worth the wait.

i second that. not worth the effort unless u back everything up. but then again, analyze ur case now. if those data are really important u will be in pain if u lose them right? now here RAID 1 would be good idea to have. if one drive dies the other has the complete backup intact. but like chozart said u have to wipe the drives clean to install RAID.

not many people know this, but E********'s, the people who built the fastest gaming pc's 2 years running, NEVER put hdd's in raid unless it's for a server. raid will actually SLOW your performance.
