I suspect some of us right now are reliving the halcyon days of watching Norton Defrag reshuffle files on their drives.
Hard drive copy fast software#
There is a way to defragment your drives on Linux (there might be software on Windows too) that can move specific files to the outer or inner edges of drives for either faster overall linear read/write speeds or lower latency between random blocks. Also, if you have fragmented files, they’ll get slower because the write heads have to move around for the varying fragments. This is kind of annoying, because per the copy time calculator applied to a single K32 101GB plot…Īll modern HDDs write from the outside to the inside, which naturally slows them down due to the areal density which is not uniform across the surface of the platter, nor across platters depending on where they are in the stack.
Once it gets full, I remember writes dipping down from 200mb/sec all the way to 130mb/sec. This above examples are with the drives more or less empty. Write speeds may slow down as the drive fills! I’ve definitely observed as the drive fills, the write speeds decline. … is anyone doing better than 235mb/sec for write speed on any 3.5" spinny rust drives? And then, the kicker…
One limit I’ve noticed is the maximum write speed I have seen anyone get when writing to an 18tb drive (any brand I think I’ve tried WD and Seagate) is approximately 235mb/sec? 235mb/sec writes How fast can they write to fill them with plots? How fast can you read off them to transfer the files off to a different location? So grabbing a bunch of 18tb drives in the name of Chia (more density = far better long term value in terms of power and hosting costs) and experimenting with them has been interesting. I’ll be honest – I haven’t looked at 3.5" spinny rust hard drives in a DECADE.
