Low read speed when mining with USB 3?
According to a test I did with H2testw, I have a write speed of 143 MB/s and a read speed of 144 MB/s on drive E. Drive E is connected through a USB 3 hub that is connected to a USB 3 port on my laptop. My computer shows the device as "Connected to USB 3.0". However, when I mine using the CPU miner, I only get a read speed of about 25 MB/s. Should it not be higher?
What could be the bottleneck here? My CPU or RAM does not max out by far.

read speed of about 25 MB/s
read & calculate
if you optimize your plots or (replot GPU-plotter with parameter DIRECT) you get best performance.
and make defrag
@Blago OK, I thought the miner only showed read speed, thanks for pointing that out. I will try to optimize the plots one day and run a defrag on the drives I use (except my SSD, because defrag is apparently not good for SSD drives).
@Propagandalf and if SSD - optimizations not needed
@Blago So if SSD, then it is not necessary to defrag or optimize? Or just one of them?
@Propagandalf it is NOT necessary to defrag AND optimize

@Propagandalf SSD drives always have the same access time in every sector. Defrag is worthless on this type of drives...

@Blago Hey mate! can i ask a thing? i have the same issue, my HDD showing 195MB/s read/write performance in benchmarks but in your AVX miner 1.1706 it shows just 50MB/s.
I've plotted HDD with xplotter, i supose plots are coming already optimized out of it. so i need to do defrag now?
what are the other options could be to increase the read speed?
here is my specs and config file:
FX 6300 6 core (67% using when mining)
8 gb DDR3 (less then 5% using)
4TB TOSHIBA x300 7600 rpm
straight SATA III conection
"Mode" : "pool",
"Server" : "pool.burstcoin.biz",
"UpdaterAddr" : "pool.burstcoin.biz",
"InfoAddr" : "pool.burstcoin.biz",
"CacheSize" : 40000,
"ShowMsg" : false,
"ShowUpdates" : false,
"UseFastRcv" : false,
"UseLog" : true,
"ShowWinner" : true,
"UseBoost" : false,
@crs 50 mb/sec - it's read+calculate
i have the same cpu, ram and SATA III

@Blago oh, ok then. thanks!
