Let me help you with this one.
I first want to thank you for sharing all those details with us but there is some more information I would like to ask you so that I can have a very and more clear image of your issue.
Please answer this:
- Was this working fine before? For how long have you been using this Raid 5?
- What is the NAS brand and model? Are you still running this RAID 5 with that NAS?
It is important to say that the cluster size depends on the file size you will handle. Here is a very good article you can check about it:

I can also confirm that rebuilding a RAID 5 with that amount of Disks and capacity of each drive will take some time so it may be expected if you find the rebuilding process slow.
I have the same problem on my backupserver. This is my configuracion:
Asrock H87 PRO4
12GB DDR3 1600 (no ECC)
64GB SSD (system) + 5X Caviar Red 4TB RAID5 (Data)
I have another with
asrock H87 PRO4
4GB DDR3 1600 (No ECC)
120GB SSD (system) + 1X 4 TB RED (data)
this is the result:
Now from those images I see the system with the 60GB SSD is in raid and TRIM function works on RAID 0 only so this may be the reason why even having the SSD a system disk the write speed on the volume will be affected.
Now my question is, Do you have both systems on RAID?
hi kevin thanks for answering.
SSD (SYSTEM) is NO RAID, and is only system (windows). Raid 5 is only for data, no page file, no sistem, only data.
I have destroyed the RAID5 and I created back when finished initializing tell you if it works well.
pd. srry my English.
Thanks just let me know!
