I have at several times had issues with consumer grade PC hardware and ZFS not
getting along. The problem is not the disks but the fact I dont have ECC and

What was the interlace on the LUN ?
The question was about LUN interlace not interface.
128K to 1M works better.
The segment size is set to 128K. The max the 2540 allows is 512K.

Hello,
I have just done comparison of all the above
