Why RAID at all? - Page 5

post #41 of 75
Oh. So you can do RAID 10 (4 drives) with the first 4 red SATA ports, and possibly RAID 10 with the other 4 on the expansion card.

Your 2 SSD's would be plugged into the last 2 red SATA ports.

Edit: forgot about your optical drives. crap.

Edit 2: that board has 7 SATA ports (6 SATA3 + 1 SATA2 [the black one beside the set of red ones]), and one eSATA port (can plug another drive into there if you really have to. Oh, and it looks like it came with an addon 2usb+1eSATA, you could plug another drive in there.

From the limited reading elsewhere on the net that I have been able to do in the interim, RAID 10 is the way to go, trumping RAID 5 rather profoundly.

Question: with these SATA port expansion cards from Promise rated a 3.0 GB/S, would that not be a bottleneck thereby negating any speed benefit of a RAID 10? On board SATA ports on my ASUS mobo are rated at 6.0 GB/S.

Time to cut my losses and make lemonade?

No, AFAIK, the only drive that would bottleneck on 3Gb/s is the Crucial C300 SSD.

Because you are using more than one drive/cable as one, your bandwidth is increased sequentially.

For example, if you have 4 drives in RAID 0, the theoretical maximum bandwidth on SATA 3Gb/s is 12Gb/s.

Just another thought to consider here is using a hot spare driver... or worst to worst, have a spare disk in a box somewhere so if you do have a drive failure, you can have a quick turn around.

I prefer the hot spare method...

@OP:

With 8 drives to play with, I think your safest bets are either RAID 10 or RAID 6. With that many drives, even RAID 5 + hot spare is risky, because when a drive fails and the spare kicks in, there is still a rebuild time. If another drive fails during that time, it's bye-bye array.

With RAID 5, I'd only go up to 6 or 7 drives, after that it's RAID 6. If the drives were 250GB or 500GB you might get away with it, but higher than that and your asking for trouble.

By the way, how full is your array and what medium do you back it up to?

I'm too much of a neophyte in this area to properly answer the question. Let's just say that with drive bays even in my CoolerMaster HAF932 Case (size of a 2-car garage with wind-tunnel like fans) being limited to 3 for HD's and would probably have to commandeer one of the Optical bays to make a 4th, I should probably look at 4 drives in total. When I say I have 8 X 1 TB of HD's, I also have another computer on my network + a USB external box.

Although Acronis zips everything and saves it, the saved files end up on a hard drive, so even Acronis has inherent vulnerability. That is why I also back up on a Samsung Blu-Ray. (yes, I know. I am truly neurotic)

Other RAIDs are fine. RAID 0.. I don't get why anyone would risk it at all. Not worth it. Period.

Double the read/write speeds

I back up my OS to a different drive, so I don't lose much IF a drive fails.

Guys, please don't leave me. I was just getting to like you.

Here's what I learned:

1) Unless I have a death wish, it's RAID 10 or 1+0, because it optimizes both speed and safe backup. Ok, Got it!

2) Now since my 2 SSD's are taking up 2 internal bays and 2 SATA ports, my 2 optical and 1 Blu-Ray 3 SATA's, I can only put 3 X 1 TB HD's internally even with the extra SATA ports from the Promise PCI card.

What about purchasing, a USB 3.0 card (my mobo usb ports are all 2.0 I believe) and have 4 RAID 10 SATA HD's in an external case.

Feel free to color me crazy. I don't mind, if I learn.

I don't think you can RAID USB drives. Maybe if you got some eSATA enclosures it would work.

Oh, and if it's the crosshair 4 formula, then you already have 2 USB 3.0 ports.
