    Buy the new Samsung S250 if you want silence. You won't be dissappointed.

    RAID 0: 2x74gb Raptors (1x8mb & 1x16mb)

    I don't think games would profit from cache really, you might want to reserve this for the OS disk instead. But 8MB or 16MB really does not have such a big influence on overall performance.

    RAID 0: 2x74gb Raptors (1x8mb & 1x16mb)

    In this Dutch review you can read on the performance difference when combining the older "GD" raptor with the newer "ADFD": http://tweakers.net/reviews/621/7 (the figures are pretty self-explanatory) Furthermore i would guess that an obsolete ICH5 controller used in the flawed Anandtech...

    yet another raid thread

    You should buy Areca is you want a good performing Windows RAID5/RAID6 solution. If you run Linux/BSD and want only speed, then software RAID0 is a good idea. Make sure you choose minimum of 128KB stripe size and make sure there is no misalignment. Either label with 1MB of reserved space or with...

    RAID Thoughts

    Risk of what, exactly? Dataloss? Then probably what happened was: - one disk either timed out or had a read/write error - the controller agressively disconnected the disk; since it has a low threshold for bad disks - you should immediately add a new (good) disk and rebuild - inspect and/or...

    Need help!

    Your data is most likely still on the drives and you can recover this data unless you do something 'stupid'. First of all, do you remember which stripesize you had used? Second, please download and burn Ultimate Boot CD (google for it) and run the hard disk utility from Western Digital (in...

    RAID Thoughts

    His data is not gone. The disks did not die (i assume), he probably made some mistakes by deleting his array by removing the CMOS configuration. So recreate the array with same stripesize and it should work. Else you have to reconstruct manually to get your data back (which is kind of a pain in...

    RAID Thoughts

    Well there is no concensus on RAID0 benefits; a lot of opinions and certainly a lot of flawed benchmarks. I'm determined to shake up things in the current status quo and popular beliefs about RAID0. This is certainly an excellent solution. You will both have a good backup (which is more...

    RAID Thoughts

    No, not I/O queueing, you did not read my post correctly. It is about parallelisation. With a single drive all I/O requests will be done in a serial order: A, then B, then C. With a 2-disk RAID0 array it is possible to do two I/O's at once, A+B, then C+D, then E+F. Thus: a theoretical...

    RAID Thoughts

    Correct. But in both cases i would argue you need backups for data you do not wish to loose. A disk failure should only result in some inconvenience - not more. If you data is important, then i'm sure you can afford some money into proper backups. After all - life is all about making priorities.

    RAID Thoughts

    At least make sure your onboard controller does not run via a PCI bus, but via dedicated embedded bus directly connected to the chipset. Then performance will be fine.

    10,000 RPM vs. RAID

    If your data is important, you do not want to loose any. That implies the usage of either RAID or proper backups. If you obey this you can happily use any RAID0 or single disks you want.

    10,000 RPM vs. RAID

    Hardware system is: AMD Athlon 64 X2 3800+ (irrelevant; disks are bottleneck) 2x1GB memory (irrelevant; RAIDTEST operates outside file caching architecture) Maxtor MaxLine III 250GB SATA/150 disks (irrelevant; numbers will vary but performance concept remains unchanged) Operating System...

    RAID Thoughts

    I disagree, i wrote the following email to him in response: Hi Jon, I would like to comment on your article named "Why RAID is (usually) a Terrible Idea". While i generally agree with you that RAID is much of a hype and does indeed complexify the system and due to crappy onboard...

    Does anyone here treat RAID 5 as a suitable substitute for a backup solution?

    By using a modern filesystem like ZFS which incorporates "history"; something that backups used to provide in contradiction to RAID. The old times of "YOU NEED A BACKUP!!!" are over, get used to it. :)

    10,000 RPM vs. RAID

    Totally untrue! RAID0 does not only yield higher STR (Sequential Transfer Rate), but also speeds up realistic workloads due to parallism. With an outstanding I/O queue the I/O requests will be divided over the available disks and the aggregate performance is much higher than a single disk. I...
