    Poor RAID1 array performance

    You seem almost convinced the issue is caused by malware/virus, but it's highly unlikely :) all my emails and browsing is done on my linux box.. my windows machine is merely there for entertainment (it's basically a media center.. has all my videos, music and photos) in any case, i did run a...

    Poor RAID1 array performance

    and to drive me even more nuts, after typing up my rant.. i tried moving a few more 1+GB files... 4-5 seconds later, all done.. at 140MB/s :|

    Poor RAID1 array performance

    i'm about to set this damn thing on fire! :( i got and installed my Adaptec 4805SAS RAID controller.. recreated my arrays from scratch and installed windows 7 64bit over again. everything seemed perfect.. in fact when moving my data back from the backup to the array i was seeing ~85MB/s (quite...

    Poor RAID1 array performance

    i spent a few days searching for good controllers and made my mind on an Adaptec 4805SAS PCIe controller with 128MB DDR2 cache, supporting up to 8 SAS, SATA, SATA2 drives (or 100 with expanders) only pain in the butt is having to rebuild it all from scratch, but i must say i'm quite excited!

    Poor RAID1 array performance

    Thanks Tony, i actually did partition the new drive setting aside 200GB for the OS and apps. and 300GB for my documents and other files. i did try to enable the Gigabyte SATA RAID controller.. and while it has a nice BIOS interface.. it couldn't migrate my Array or create a new Array with the...

    Poor RAID1 array performance

    So i plugged the drives into my linux box and ran smartctl. one of the discs reported a few errors, namely: REALLOCATE_SECTOR_ERROR and SEEK_ERROR_RATE being higher than the threshold. kinda strange the intel matrix controller didn't pick up any warning though. anyway, i bought two new drives...

    Poor RAID1 array performance

    i ran some tests copying a 1.5GB file across from one drive to another back and forth and following are the results: Legend: C: (2x 250GB RAID1 Array) D: (1x 500GB SATA Drive, standalone) E: (2x 1TB RAID1 Array) E -> E ~125MB/s E -> D ~70MB/s E -> C ~2MB/s D -> E ~125MB/s D -> D ~60MB/s D ->...

    Poor RAID1 array performance

    kjv1611: to be honest i think i've had the issues right from the start, but always thought it was photoshop's fault, till one day i got fed up of it and tried to get to the bottom of it, and noticed storage being the bottleneck.. i ran all kinds of tests since my last message.. no...

    Poor RAID1 array performance

    Following are the drive specs: Drive C (250GB) RAID1 components: WD2500JS: SATA 3 Gb/s interface, 7200RPM, 8MB Cache, 8.9ms seek time Drive E (1TB) RAID1 components: WD10EADS: SATA 3 Gb/s interface, 7200RPM, 32MB Cache, 8.9ms seek time so sure they're not state of the art, but surely they...

    Poor RAID1 array performance

    I've been noticing lately that my newly setup system is EXTREMELY slow to respond at times! for instance if i create a new document or photoshop file.. the moment i click anywhere on the screen the software wont respond.. and the windows performance monitor actually shows the process is waiting...
