what do you say about RAID setups ?

post #1 of 25
Thread Starter 
hello guys...

I have been thinking of making a RAID setup for my upcoming build / upgrade for a while, but lately I heard that the whole RAID process is not worth bothering about because it will make the boot time more longer to get to Windows, so I would like to ask how long the boot time will increase with RAID setup ? I am thinking of making a RAID0 setup, so what do you say ??

also SSDs seems to be not an option with its prices are still high.

how much speed I would get with RAID o setup with 2 drives 7200 RPM each ?

- and does the buffer cache amount make any difference in this ?? so is 32 MB better than 16 in RAID 0?

also let me tell you that the current avg speed of my HDD is about 60 MB, so how much should I expect from have 2 HDDs 7200 each in RAID 0 ?

and please tell me how longer will it take with 2 HDDs in RAID 0 to boot to Windows vs. 1 HDD ??

thanks in advance.

I've found it boots to windows faster even with the extra config it needs to run.

I get between 120-150mb/s transfer rates.

If you have the right drives (Samsung F3 1TB or WD Black 1TB or bigger), then yes RAID0 is a must have . Just make sure you backup your data. The data doesn't exist unless it exists in 3 places at once. RAID-0 means twice the chance for failure.

The increased boot time, honestly...is about the same as a single drive on my rig. I have my BIOS, then my RAID BIOS, then Windows boots up. With a single drive, I skip the RAID BIOS. But, everything is absolutely faster. I load into Windows almost instantly. Programs open as soon as I click them. I'm always the first into a game.

Like I said, just make sure you have a solid backup solution for storage.

then I think I will put 2 HDDs in RAID 0 and have the third one for backup.

but returning to the point of the difference between RPM speeds, will it make any difference between putting 2 HDDs in RAID0 7200 RPM each Vs. 5400 RPM or 10000 RPM each ??

also what about the same case for buffer amount difference ??

It all depends on the drives themselves. You want to match RAID drives as perfectly as possible.

If you're buying new drives, look into the Samsung F3 1TB or the WD Black 1TB's. The WD Blacks are more expensive, but will DEFINITELY be a better operating system / daily use RAID setup. The Samsung's will be faster for storage. Either option is very fast, so it really doesn't matter too much.

I'm on 2x Samsung F3's, and I love them. Best bang per buck drives. They're regularly on sale for less than $60 shipped each.

Here is two F3 1 terabytes in raid-0. Use another drive for back up using acronis in case something weird happens.
post #7 of 25
Today RAID 0 is really a waste of time. Anyone looking for the increased performance in a home machine will be looking at an SSD for OS/Mechanical for data combo.

RAID 1 is great for data redundancy, especially if you have lots of data you don't want to lose.

Seriously, buy a 64GB SSD, pop windows on it, and buy a mechanical drive for you data.

I had a relatively fast RAID 0 array, for a two disc array anyway, and my SSD KILLS it.

That was the RAID 0. SSD kills it. If you think you are going to have a RAID 0 array that performs much better than the screen above and still be cheaper than an SSD, well go ahead I guess.

What's your capacity requirements?

As stated, SSD is the way to go if you are looking for a substantial upgrade that affects every way you use your PC.

still there is no clue about the difference between the HDDs RPM speeds, neither the difference in the cache amount.

no idea ?

I beg to differ. Loading times in games will benefit greatly from a good RAID0 setup. Good luck loading your entire game database to a 60GB SSD, along with Windows.

Here's my RAID0 setup for comparison:


And my dad's rig uses an OCZ Vertex 2 60GB SSD for his boot partition. I can honestly say, there is LITTLE difference between my RAID setup, and his SSD. Only difference is the access time, which isn't THAT big of a deal when you have a fast access time already (8.0ms is pretty fast). The only other difference is that I have 2TB worth of storage, he's only got 60GB. I'd rather have the 2TB of storage for the money over 60GB.

RPM speeds matter to an extent. 5400 RPM drives are going to be noticeably slower than 7200, which will in turn be slower than 10000 RPM drives. However the Samsung F3 and the WD Black drives that I've mentioned are JUST as fast as the 10000 RPM drives anyway. So there's no point in going over 7200 RPM, as long as its a good drive.

5400 RPM drives are perfectly fine for storage only purposes though, or backup.

Cache is honestly a marketing gimmick.

What matters the most is the exact model of the drives in question themselves. Again, Samsung F3 1TB and WD Black 1TB (and bigger) are the drives to buy.
