I’ve read a couple of threads regarding poor performance for the EX4. 50 MB/s does seem slow and I’m pretty sure that’s not a limit of my 1000 Gbps network (Linksys Switch - all Cat6 all 1000 ports).
So to test:
- PC to EX4 = 50MB/s
- PC to PC = 100MB/s
- PC to USB 3.0 drive = 150+ MB/s
I read the two or so threads about setting the EX4 into link aggregate mode which means I’ll need to setup my switch into one of the support link aggregate modes AND setup each PC (that has two 1000 Gbps ports) to link aggregate via OS.
So after doing all this, I’m at about 52MB/s on average. So my assumption is that the bottleneck for the EX4 is in it’s internal CPU/RAM and link aggregation just doesn’t improve performance to any significant degree.
Has anyone else been able to exceed about 52MB/s write speed on the EX4 (RAID 5)?
