Thank you for your answer..
Can I use this drive(/s) for daily purposes (media storing etc) or is this diskspace reserved for BURST at start?
There is no need for high speed internet? Will 10mbps be sufficient?
No space is reserved with files containing hashes that needed to mine. So space is occupied and you can't store other data.
A common internet is enough, not much traffic to send info to pools, the most important thing is the hdd/sdd reading, faster you scan your hashes, a bit more possibility that you submit in time your best results.
