Ok, I will run burst test tonight, is there a way to run it on all drives continuously? I have 12 in total. Also, how do I tell if it is a problem with the controller oppose to the drive? If the majority of the drives are showing good does that point to the drives that are not showing good as the problem?

Ok, Read stripping and Network I/O boost were checked.

Ok, burst test results indicated a average speed of 151MB/s per drive I don't see a setting to turn on or off Network IO Boost. I didn't find it under settings, drivepool. Is this a hidden feature?

Ok thanks, I will try your suggestions when I get home this evening. Real time duplication was already off but I cannot verify the other settings until I get off.

Thanks for the replies. Read and write speeds to nonpooled drives are normal, fast from all of my client PCs. It's only slow when I copy or move a file to the pool from any of my client PCs. When copying or moving files from my pool it is just as fast as my read /write speeds that I get when moving files between my client PCs and non pooled drives on my server. Scanner shows that all drives are healthy. How do I do burst test? Personally it seems like all signs are pointing to a problem with my pool or pool setting.

I am having some very sporadic write speeds to the drivepool, it will peak at 16MB/s, go as low as 0MB/s, completely stopping, and finally bouncing between 400KB/s to 1.5MB/s, However, when I write a file from the drivepool to any computer on my network the transfer is fine, between 60MB/s to 90MB/s. Write speeds to a folder on a non-pool disk is also between between 60MB/s to 90MB/s. I am running StableBit.DrivePool_1.3.3.7563_Release.and the pool is showing 100%. My drivepool is on a frankenbuild WHS 2011. All of my clients are running Windows 8. Pinging from my clients to my server is <1ms. I also tried using Robocopy or Teracopy but neither didn't help. I also performed the following optimization tasks obtained from wegotserved.com: For the NIC: Flow control: on (client and server) "checksum" or "Offload": Off (client and server) jumbo frames: off or default (client or server) run "netsh interface tcp set global autotuninglevel=highlyrestricted" in an elevated console (command prompt) on *all* computers (Vista/Win7/Server 2008(R2)/WHS2011/SBS2011e) Services/programs: Windows Media Player Network Sharing Service: Disabled/manual Windows Search Service: Disabled (and probably a good idea to move it to another drive anyhow, or at least d:\) Install the "Remote Differential Compression" feature on the server, or uninstall it from all Win7/WHS2011 computers Misc: Run chkdsk on all the disks. Full is best, but just to make sure Defrag. Is there anything that I can do to remedy this?
