Uz pisi opravdu naposledy, protoze tomu evidentne vubec nerozumis. Nema cenu presvedcovat nekoho, kdo nechce. Docela mi vadi Tvoje hlasky ze typu "o co sa snazis a trepes nezmysli "
Nesmysly tu netrepu já..
Tady jsou testy Tveho radice tak se na ne podivej.

Hned pod druhym grafem je komentar.
The checksum-based arrays have lower speeds than the RAID0, but that’s logical: one and two blocks are lost in each stripe with RAID5 and RAID6, respectively, due to the writing of checksums. As a result, the read speed degrades when all of the disks are being accessed. It is clear how dear in terms of performance the loss of disks is for the degraded arrays.
Uz sem opravdu nenapisi nic, ja chtel poradit a ne aby me tu urazel nekdo, ktery nic nevi..
