@haitch Thank you very much for the info. I have also an ethereum rig that I'm planning to use for GPU plotting 6 drives at a time.
@manfromafar Yes I got the Seagate archive drives 8TB they were on sale so I got bulk ordering. The problem is that I do not have another 8TB drive to plot onto. Actually, I know that they have half the head that is why they are slow but I thought that this gets you affected only if you delete and copy new files on them??? Or maybe I have not understood the technology right.
@rds I got 65x Seagate Archive 8TB drives so I've written it correctly.
@iKnow0 They are old WD Enterprise Edition 500GB HDDs. And you are correct sir they are sata2 maybe that could explain the slow time ...
Thx fellas I will try the XPlotter. I will be posting often :D as @iKnow0 said there is a learning curve. I just hope that it isn't much steil of a curve :)
