Do Raid Setups Really Make A Difference?


Windows 7 Home allows JBOD and RAID 1 while Professional and Ultimate add RAID 0 mirroring. drive A and B can both fail. For my Vista Business image, the fresh install option was chosen to get the necessary drivers and software inserted into the OS.Just familiarize yourself with your motherboards BIOS, which SATA ports Posted on 2007-02-06 18:15:50 WaltC Hello Jon!

From what I've read, they have already resolved (or are very close to finalizing) those problems. For example, if you are editing a video, and when doing so your CPU usage is pegged at 100%, then you can be fairly certain that moving to RAID0 will not I have 3TB's that I will use separately for storage. Video editing is a good example of when RAID0 might make sense.

However, I do have a background in engineering, and it appears to me that you've both left out an important component. For more advanced users, a two-disk configuration will usually be faster. Once the game/level/video is loaded and everything is in memory that RAID isn't doing you a bit of good.

  1. I actually signed up here to briefly comment on your opinions as expressed about RAID in general.
  2. Advertisement Sponsored • RAID 2 stripes data like RAID 0, but at even smaller level (bits instead of blocks) and uses additional hard drives and what's called Hamming code for error
  3. SSDs will get you much closer than any hard drive, but no storage media will actually ever reach the maximum transfer rate of the controller.

  6. Thus, the failure rate for each of the two drives running IDE is *exactly the same* as it would be for each of those same two drives running in a RAID

Which really just means a bundle of hard drives acting like one superharddrive. What Is Parity In Raid With tape you may not even be able to recover the data due to a 25-30% failure rate of tape media.

To be clear, there are definitely times when RAID is a good route. If I remember right, this used to speed things ups a bit for PATA drives. Like Show 0 Likes(0) Actions 10. Write operations are much slower, as the media itself is the bottleneck. -=Cameron Kamal says: January 22, 2016 at 6:09 am Hi, Can you please tell me what is the maximum

By using two drives in a RAID configuration, you can acess your data faster. It's implemented in specific infrastructures requiring high performance but not a high level of scalability.

First of all, let's consider a situation where a person purchases two of these: Western Digital ATA100 80.0GB WD800JB's, just as an example. OK, so what is the difference between the two systems?

What Is Raid Technology The sum total of that investment may be prohibitive for his workflow, since he alreay has the QNAP.A practical limitation at this moment is that Intel is still working on the

Re: To RAID or not to RAID, that is the question hbannister Dec 17, 2009 11:16 PM (in response to Harm Millaard) I have scoured this forum for the past couple Performance & Maintenance Core I7 did not make that much of a difference after allI have a Pentuum D Core 2 Duo desktop with 4G Ram ( 3G in use) running This RAID level provides better performance than mirroring as well as fault tolerance. Now, you still need to be sure that the speed of the hard drives is the right place to focus. Raid Performance Comparison

Posted on 2012-11-01 04:59:19 Frank Van Der Mast Jon, You've written a very compelling article. I wanted to create a partition for games at the beggining of the 2nd drive (the left side) as i heard it increased performance to put games in anoher drive and Alternatively, never touch exposed contacts or electronics. With hard drives getting cheap, the army of hard drives you need to make this happen is easier to get going, so you might see more of it.Just to be clear:

Unless you're building a gaming-only system, RAID-0 on a single-user system is a BAD IDEA.The simple solution is to get a single large disk, and use it with ONE partition.

It is not just a question of hassle, but of recovering quickly from the loss of a critical ws, which always seems to happen with deadlines.

It combines the mirroring of RAID 1 with the striping of RAID 0. Notice that this guide also applies to SSD's, with the expection of the parts about mechanical failure.What is a RAID?RAID is the acronym for "Redundant Array of Inexpensive Disks". How can you have RAID 1+0 with two disks? What Is An Advantage Of Raid 5 Over Raid 1 Quizlet The game benchmarks will have a near zero improvement, except when a map load is performed (I haven't seen a benchmark that checks this).

It writes, or mirrors, data to multiple disks, so you've got multiple hard drives that are exactly the same.

That's a great place to start! For example, with RAID 5 on a server that has a database that many employees access in a workday, there could be noticeable lag. •RAID 6 is also used frequently in Safety first! We say the rotational latency of a single disk is equal to 1/2 the time of a single rotation of the disk.

The double parity in RAID6 makes it ideal for NAS applications.The performance gain is slightly lower than with a RAID3. Possibly the read speed is enhanced in raid1, because of combined reads if the ICHR10 or Marvell support that.
