  1. Yes they are in a 4 Bay USB 3.0 enclosure and they are the same kind of make and model disk but different serial numbers of course.
  2. I am having an issue with the naming the unassigned devices that are appearing as the same drives. I have 3 1TB USB drives. I am trying to rename each of of the mount points and mount them after but the when I change a name one of the drives it changes for all 3 of them. What is the workaround for something like this?
  3. I took the parity drive out of array and used it as the cache drive. That is how I am able to obtain such high speeds now. I am going to leave it this way until I finish ripping all of my movies down which is about another 600 discs or so . For me all 8 of SATA II ports are on the motherboard. I don't have any Bus based controllers installed yet.
  4. This is what I came up with! With 120GB SATA 1 drive installed as a cache drive. I was getting writes speeds of 23MBs. Took 1.5TB SATA 2 parity out of the array and added as a cache drive. Copied files directly to cache share and received transfer rates between 76MBs and 102Mbs on the Writes Copied files to the array and received transfer rates between 18Mbs and 20Mbs on the Writes Some reason I notice there is no files in the cache drive that was copied to the array. I think the files copied directly to the array and by passed the cached drive. Even though the share has cache enabled. Maybe the moving of the drives without a reboot cause the problem. Before I reboot the server I changed the cache back to the 120GB Sata 1 drive and did a speed test copying files directly to the cache share. Copied files directly to cache share and received transfer rates between 38Mbs and 76Mbs on the Writes Rebooted server With 120GB SATA 1 drive still installed as the cache drive I copied files into the array and received transfer rates between 19Mbs and 22Mbs. I did verify the that files are to the cache drive and not directly into the array. I believe anytime you are the array offline and moving drives around you should reboot immediately afterwards. Changed cache drive from 120GB Sata drive to 1.5TB and rebooted server and received transfer rates of 20Mbs to 24Mbs So I came to the conclusion that the speed are faster when copying files directly to the disk than they are when copying files to the array shares. So my question is do I only have to copy files into the user shares (slower copy) or can I copy files directly to the disk shares (faster copy)? Will I have a problem with Split Levels by doing that? If thought I do not think that is a problem giving that I am copying the directly to the disk so I am creating my own Split Level? Finally, if it is okay to copy files directly to the disk will that create a problem with the parity sync? I am thinking not because the parity sync is happening at block level and not file, folder, or share level but I am just making sure.
  5. I appreciate all of you r replies. So far I have checked the 500GB drives and yes they still had the 150 jumpers on them. I feel like such as idiot because I thought I already checked for those. That is what I get for trying to looking for something with limited lighting. I checked the Syslog and they are all showing up as 3.0Gbps except for the 120Gb hard drive. I already knew that the drive was at 1.5 speed . I will play with the NCQ , AHCI settings, do some transfer tests and report back. I posted the updated SysLog for you to see if there are any other changes that occurred since the removal of the 150 jumpers.
  6. What does 80Mbps = 10 MBps mean? Are you saying they are lying about getting 80Mbs on the read speeds with a cache drive installed? And if that is do why are my speeds are the same whether I disable the parity or add a cache drive or leave parity intact and copy files directly into the array? Also, why would my sata ports are be stating SATA link up 1.5 Gbps (SStatus 113 SControl 300) instead of SATA link up 3.0 Gbps (SStatus 123 SControl 300) when I have all SATA II drives attached?
  7. I have the Gigabyte EP45-UD3P motherboard running Unraid 4.5 beta 6. I am getting slow speeds on the writes and the reads transfer rates and I am trying to find out why. I get the same speeds with or without a cache drive installed and something slower on the cache reads. I have tried replacing the network cards on my desktop and the Unraid server with Intel PRO/1000PT Server Adapter with no better results. I am seeing speeds on the Writes between 10MB and 18MB transfer rates using TeraCopy . I am seeing between 10MB and 12MB transfer rates on the read speeds as well. I notice in the SysLog that even though all of my hard drives are SATA2 some of them at max speed is defaulting to 1.5Gbps instead of 3.0Gbps bus speed on the controller. All of the controllers are configured in the BIOS to AHCI. I only tested with DVD files for the best results. I am going to attach my SysLog to the thread. I am remove the Mover lines from the log because it was too big to attach. I guess what I am trying to find out if anyone else is experiencing the same types of problems and get some suggestions on how to fix this. Some of the threads I read stated that they are getting the same speeds as mine for Writes without the cache drive installed and I am fine with that but on the Reads and Writes with a cache drive installed some are claiming to get almost full disk speeds 60-80Mbs. I am not seeing this when connected to Unraid. I am seeing transfer rates between 80-100Mbs when transferring file between Windows XP and 7 and Ubuntu 9. And this is without Jumbo frames enabled.
