You can also use 'systat vmstat', which shows the same info, but I
prefer it; with a window with more than 24 lines, it can show more

I would try to test the drives with dd, separate from raidframe.

But, a 1TB drive, assuming 80 MB/s, should take about 3.6h, so
someth9ing is off.

Your iostat output shows 1.5 MB/s, which is not healthy.

Also, you might check your SATA cables.
