Raid 1 vs. Raid 5

How much faster is Raid 5 that Raid 1? I am not as concerned with data protection as I am with speed. Is Raid 5 demonstrably faster?

    It seems like a well done explanation, so I hope it helps you choose which RAID you wish to implement, if it even does that. :smile:

  2. Raid 5 have good read speed but bad write speed.
  3. Good info there btvillarin. Simple, clear and concise. That's a bookmark post. Thanks.

    With a good controller the bad write speed is minimized, but that is true.

    What are you going to be running? I'd tend to say RAID 5 would be better, but it's not quite clear-cut.

  5. Faster - yes
    Just as fault tolerant- yes
    More Costly- oh yes

  6. RAID 5 will be faster at writing then RAID 1, and MUCH MUCH faster at reading. Keep in mind RAID 1 is a mirrored set and it a hair slower then a single drive. In RAID 1 you lose half your space, in 5 you lose 1 drives worth outta the array. If you are not interested in data protection as you say, go with RAID 0 (striped set) as its the fastest. Just keep in mind with RAID 0 that if one drive dies ALL the data is lost!!

  7. Dood, if you want speed, use Level 0.

    What's the frequency, Kenneth?
  8. No problem, broham. It's good to be lucky sometimes... :lol:
