Inconsistend HDD Speed and Disk spin down

Featured Replies

Hoi everyone!

 

I have recently upgraded my HDDs in my server:

(AMD Ryzen 5 2600X, B450M PRO-M2, 16GB RAM, 256gb Cache SSD). I have upgrade from 3x 2TB WD reds to 4x16tb Thosiba Enterprise Capacity

My Transfers to my Plex share are slow and inconsistent (see picture 1)

 

If I test the speed I got the following results (see picture 2 and 3. 3 was with "reconstruction write" on in the seetings)

I don’t know why this is so inconsistent

 

I have tried using “Auto Turbo Write Mode” and setting reconstruction write in the Settings. The parity is done and valid. For the Plex I don’t use the cache Drive.

 

I have also noticed that the disk do not spin down at night, however I have set the spin down time to 30min

 

Has anyone a Idea why this is behaving that way?

If you need more Information please just ask. (I am not so familiar in that topic so don’t know what is required)

Write mode won't change anything since it's a read test only, the inconsistency could be due to disk issues, where some areas are slower, though kind of strange with new disks, I assume.

 

 

Is the Windows graph with or without reconstruct write? Also post the diagnostics saved during a large file transfer with reconstruct write enabled.

The Windows graph ist without. It is a lot better with reconstruct write enabled. 

 

The Drive are not new. I had used them bevor for a diverent projekt, and there were unused for about 1-2 years.

Then it can really be the drives.

Can this be a sign of failing drives or is this "normal"?

It's not a great sign, but i doesn't mean that the drives are about to fail, keep monitoring.
