RAID-1 performance with WD Gold 2TB WD2005FBYZ-01YCBB3

[overvolt]

I do not have memory about reading before any HDD product review as is this one!

This including only filtered information, hardware performance results along information's relative to specific HDD maintenance tasks and even the required timing for its one.

I will add this WD Gold at my wish list too 
But I think that the true Gold here is the style of this presentation.

For the shake of completeness    I did test and run ATTO HDD benchmark.

If some one has greater faith to ATTO benchmark he can see WD2005FBYZ RAID-1 performance at the screenshot below.

I could not resist my self, about running ATTO so to inspect my older WDC-WD740GD-00FLC0 which were replaced by the WD Gold.

Its remarkable the performance of WD Gold, not only at Large file size as this were expected.
But especially at small file size of files,  in which WD Gold this provide several times larger of  Read/Write bandwidth.   
At 512N (bytes)
6.6 times faster READ
10.2 times faster WRITE

In other words, this 2TB WD Gold as OS drive, this is a truly golden choice, because nothing can slowdown this beast.

I go my pair of WD 2TB Gold at winter time (six months ago).
At my large workstation PC case, RAID-1 array this is actively cooled, due 120x120 DC fan (600~1500rpm).

January 2024
When ambient was at 18C, RAID-1 array temperature this was at 22C, while two other HDD with passive cooling they were at 33~34C.

July 2024
Ambient this is now 32C, RAID-1 array temperature this is 35C, while two other HDD with passive cooling they are at 42~44C.
(Active cooling DC fan is now at 1380rpm and just audible).

These are excellent statistics, and I am surprised of how well WD Gold ( HGST Ultrastar) HDD design behaves, speaking of power efficiency, heat dissipation along operating temperature.
My other two HDD with passive cooling, these are production of 2005 and they stay idle most of the time.

As HDD activity benchmark, I had use Norton Ghost, the backup process needs 20 minutes so to finish.
With 32C ambient,  RAID-1 array at 35C,  twenty minutes of constant activity (backup task), temperature this elevated at my RAID-1 array to 36C. 

The good design of my PC case (mini server) worth's the most bragging rights. 
But most modern HGST Ultrastar (WD Gold) they are very good performers, that neither a professional workstation PC this it can stress them enough.
