WD Red Pro
4 TB, 3.5"
Question about WD Red Pro
I have a Synology 1517+ NAS equipped with 5 x 3Tb-WD Red (Raid 6). Two of my hard drive are dead. I would like to replace these two 3Tb-WD Red by two 6Tb-WD Red PRO. Will this configuration work knowing that there is a mix of WD Red and Red PRO with a mix of 3Tb and 6Tb capacity (I am fully aware about the fact that ony 3Tb of the two 6Tb-WD Red PRO will be considered by the NAS). I would also have 2 new 6Tb-WD Red PRO that work at 7200 rpm (with 256 Mb RAM) while the 3 remaining 3Tb-WD Red are working at 5400 rpm (with lower memory 128 Mb RAM).
In my experience, you can mix hard disks of different sizes (that's what I have in my DS414).
However, you should pay attention to the same speeds, had also tried to add a 5400 rpm to the existing 7200 rpm, it does not work !
