2x 250GB serial-ATA in RAID-1
OK, so I'm constantly updating specs for a build that will happen some time
after the new GPUs are all released. I'm looking at going RAID-1 with 2x 250GB drives, for back-up and read-speed reasons. I'll probably look at getting 2x Western Digital Caviar SE S-ATA 250GB WD2500PD drives, but I'm wondering what effects the reduction in write-speed has with running RAID-1. What operations does it become noticeable or detrimental during? http://www.storagereview.com/article...D2500JD_8.html |

I'm not sure what you're looking for here, but obviously determining exactly
what would be affected varies greatly based on what you intend to do, what applications are installed, etc. I use my IDE ATA 2 x WD 200GB RAID1 for data storage, long term storage. I seriously doubt that most users would even notice the difference between RAID1 and non-RAID1 at all, I certainly don't. Not unless the HDs were substantially different in model, speed, buffering, etc. Perhaps if one was 5400RPM w/ 2mb buffer and 12ms response, the other 7200RPM w/ 8mb buffer and 9ms response, you might notice, obviously RAID can only perform at the lesser of the two HDs. But beyond that, unless you're benchmarking, the differences are going to be virtually imperceptible. I also keep my OS (and anything else I consider expendable) on two other HDs, in RAID0 (stripping), not only negating the issue, but improving it beyond a standalone HD! Of course, one other option is RAID0+1 (your mobo might not support this), which provides BOTH redundancy and performance using 4 HDs. Let's put it this way, if you had two machines, A and B, and each was indentical except for one being RAID1, the other NOT, and sat the same person in front of each and asked them to tell you which one was RAID, they'd do no better than flipping a coin! For me, that's says it all. Now, if you're configuring this for a server, where you intend to nightly update a database over several hours, I suppose *then* you might notice the RAID config takes more time, maybe by a few minutes. Any situation that is severely and inherently write-intensive is more dramatically affected, but for the average home user, its a non issue. HTH Jim "Cuzman" wrote in message ...

What operations does it become noticeable or detrimental during? http://www.storagereview.com/article...D2500JD_8.html I know this is not what you asked, but I couldn't help myself. :-) If you want safety, don't use mirrored disks... (I know I might get flamed now, but mirrored disks only protect you against HD-failure!) Use one disk in your system, and an external for backup. The additional cost for an external disk is minimal. Your setup will NOT protect you against: Theft, Powersurges, accidential deletion, Virus etc. Using an external HD that is NOT attached to the system will not be affected by lightning etc. If you keep it in a safe place thieves might also miss it... Then you just find time to syncronize the disks once in a while when you are sure the original is OK. Hopefully just a litle bit of your data changes, and the time needed should be minimal. Just my two cents. Rune |
