Miguel,
You have trouble with writes or reads?
From Proxmox or from a guest VM?

Sorry I meant reads, pveperf:
root@myserver:~# pveperf /vz/
CPU BOGOMIPS: 42669.12
REGEX/SECOND: 935261
HD SIZE: 1809.50 GB (/dev/mapper/pve-data)
BUFFERED READS: 94.56 MB/sec
AVERAGE SEEK TIME: 17.88 ms
FSYNCS/SECOND: 10.15
DNS EXT: 16.93 ms
DNS INT: 23.36 ms (ibertrix-node2)
from specs from the manufacturer average seek time is around 8 ms
writes are like this:
root@myserver:~# dd if=/dev/zero of=/mytempfile
^C15210305+0 records in
15210305+0 records out
7787676160 bytes (7.8 GB) copied, 52.1116 s, 149 MB/s
performance from a VM (I have 5 VMs running in this 32 Gb RAM server)
running Centos 6.8:
root@vm [~]# dd if=/dev/zero of=/mytempfile
^C9360176+0 records in
9360176+0 records out
4792410112 bytes (4.8 GB) copied, 112.571 s, 42.6 MB/s
The settings for virtual HD are: qcow2 and writeback cache

Considering hdparm reports same speed for the underlying disk and the
soft raid seems some settings that need to be set. I´m asking here
just
to be safe in terms of proxmox and not to be too aggressive. My
impression is that with ext3 I got better performance.
You can achieve the same performance and security level with ext4 as
you did with ext3 by using this mount option: barrier=0
