Re: [H] Freenas & Nas4free any experience?
I'm inclined to blame the 3ware. I never used one that impressed me in the slightest, though 5mbps certainly suggests a deeper issue. In any case, I'd consider snagging a Dell PERC6 or PERC H700 off ebay. I just did a series of RAID5 and RAID6 tests on a bench PERC6 and a used PERC H700 I got off ebay for $100. Both of these cards are based on slightly altered LSI MegaRAID adapters and even support using LSI's management software, though note that the PERC6 does not support physical disks > 2TB. All tests performed using 8x2TB Toshiba HDDs. CrystalDiskMark sequential using a 4000MB test file: PERC6 RAID5: 791MB/s read, 485MB/s write PERC6 RAID6: 671MB/s read, 398MB/s write H700 RAID5: 1086MB/s read, 1015MB/s write *this is effectively the theoretical peak potential of the underlying HDDs* H700 RAID6: 937MB/s read, 704MB/s write Disks are also important. Either buy RAID-rated disks, or Toshiba's DT01ACA series. Expect everything else to cause problems.

I have been working on retiring an old freenas box so I built a nice server with spare parts running freenas 9.xxx x64. I have a hardware raid array (3x3TB raid 5) on a 3ware 12 port contoller. The interface is way different than what I'm used to but I can deal with that. The transfer speeds are horrible though and pause about every 20 seconds. I'm only averaging 5 mbps compared to 55 MB/s on my drobo5n. This is actually a backup for my drobo5n that will get powered on about 1x every 2 mos to update any new files, etc. I've heard nas4free is a little more solid compared to newer versions of freenas. Never tried it though. Suggestions? Write caching is turned on - still slow as hell lopaka
Re: [H] GPT_disk_moving?!
I've never experienced what the OP describes, despite working with a fairly large number of GPT disks with my large arrays and moving them between OS installations. I'm pretty sure there's something else going on here. Excepting being mindful of OS (and utility) support, GPT does not require any special handling compared to MBR. -Original Message- From: Hardware [mailto:hardware-boun...@lists.hardwaregroup.com] On Behalf Of Thane Sherrington Sent: Tuesday, July 8, 2014 9:48 AM To: hardw...@lists.hardwaregroup.com Subject: Re: [H] GPT_disk_moving?!

Re: [H] GPT_disk_moving?!
Thanks for this. I have a box full of GPT drivesI was wondering what I'd do if I needed to upgrade the host mobo...as it is starting to get old. As all I have are mkv rips from my blu-ray collection, this would be a LOT of work to do over. So one day I just want to move the drives over to a new box.

Re: [H] GPT_disk_moving?!
one of my SSD's are listed as GPT, NO idea how this happened. Only used for storage. There two identical, only is listed GPT when I run Diskpart Thought about trying to get rid of that, not sure why. They are only 250gb drives. no harm I suppose, just no idea where the gpt came from. fp At 06:14 AM 7/8/2014, joeu...@chronic.org Poked the stick with: OK, I found out what needs to be done & since no one else knows I thought I'd share it with you.
