OP Here, To further this information, i have now copied another Tb worth of files from the same drive in one copy instance that are mixed some 55Gb, 1Gb, some 20Kb, etc successfully. However no matter what i do i cannot get that 1Tb single backup image file to copy, it always errors out around 169Gb

Hello all, so heres the scoop: I have recently set up my unraid array and installed unassigned disks and krusader to copy files from a hard drive i had originally had connected via usb 3 but now i have shucked that drive and connected it directly to the motherboard of my unraid machine The drive is a seagate backup plus 4tb drive, so its actually just a seagate 7200rpm 4tb consumer drive I have mounted it under unassigned devices this seems to be a part problem and part oddity? So the problem(s) i am facing is this: 1. I have a .mrimg file that is 1007Gb or 1Tb file i am trying to copy directly from the unassigned devices drive to my unraid array in a user share i made under 'user'. The path is listed 'Custom Path: media: user: myfolder' . When it gets to about 169Gb copied no matter if the drive is connected via usb 3 or directly to the motherboard i encounter an error where copy stalls and shows an error message 'Cannot read "backup.mring". Copy failed' there is an option to retry and an option to cancel the copy. This is my main problem, and i am asking are there is any solutions for this issue? Has anybody come across this before? 2. If i do click retry, the copy speed reduces from the max speed of my drives (170--190Mb/s) down to about 105-125/Mb/s, and the error persists at the 169Gb mark. Also any subsequent copies after this of any other file on the drive is slowed to this speed. Has anyone encountered this issue, is it some kind of protection due to the failed copy? Thankyou all for your help!

Hello all. Thankyou for your replies. To be clear here i am going for multiple write performance over reliability here. I understand that the parity drive in raid zero could fail, but it is not double the chance of failing, it is the same as if there was one disk, and it failed. If one of the parity drives fails in raid 0, i will simply pull the drives, replace them both and get a 4tb spare to keep from it. I cant seem to find any clear answers anywhere about this particular use case, so i will just attempt it and post the results. Now that my kingston 16gb se9 has arrived, let the trials begin....

Hello all, so i am posing a 2 part question or 2 different questions that are related here depending on how you look at it. I am going to set-up an unraid server for multiple uses as most of you here have, and i am going to use 5 disks and 1 ssd off the hop The setup i am aiming for is as follows: 5 disks, 4-4tb and 1-8tb --- configured 2-4tb in raid 0 on the motherboard for parity, and the other 3 disks as file storage on the hba 1 ssd -250gb 850evo as cache on the motherboard sata port motherboard is asus prime z370-a hba is lsi sas9211-8i flashed to it mode 20.00.07.00 - with bios for now So, my question(s) are: 1. can i mix usage of the motherboard ports and hba ports for this array, or will there be conflicts. Has anyone done this before? 2. Can i configure the raid 0 parity drive on the motherboard hardware, or should i be using the unraid software to do the raid 0 config of the parity? Also, can i use another motherboard sata port for the cache drive and put my data disks on the 9211-8i (related to question 1) I have tried to find some info on this abroad but not as of yet been able to find any clear answers. I am intending on using every sata port available in the system at some point as i expand my array, but are there any known issues with mixing motherboard sata controllers and hba controllers for a single array? Any performance losses, conflicts, etc? Has anyone done this or similar config? Thankyou All for your Help!
