Putting a WD Red Pro 4TB into a server with WD Red 4TB Drives(Not Pro)

[LexenZ]

Hi everyone,

 

I have a question with regards to whether if I were to buy the WD Red Pro 4TB and slot it to my server(Which already has 3 WD Red 4TB drives, not pros though), will it be able to use it to its fullest potential of 7200rpm? Or will it bottleneck due to Raid 5 setup which I had.

 

PS: Apologies if I posted the wrong topic here, since it's NAS related I am guessing it should be here...

It'll run at 7200rpm still, that's non negotiable with hard drives

 

On a serious note, it'll work but you'll probably not notice it. RAID 5 will have already sped up data transfer, adding a slightly faster drive will either speed up the transfer slightly, or have no effect on speed at all.

Thanks for the info Jlryan

So.... if you were me, will you purchase the red pro or the red normal?

No problems

 

It would depend on price mainly, if I could get the pro's for a good price they would definitely be my choice, and then slowly overtime replace the non pro's with the pro drives if/when they go on offer, and re-purpose the drives you already have for other computers, or keep them as a cold spare in case of any failures in the future.

Hey LexenZ,

 

RAID controllers generally limit all drives in an array to the speed of the slowest drive and to the capacity of the smallest. The drives  should be able to work, but the performance of the WD Red Pro drive will be bottlenecked to the other WD Red drives, regardless of the higher rpm.

 

Using drives with different speeds in the same RAID array increases the risk of a drive dropout or data corruption due to high chances of miss-alignment of the data when written. I would recommend to stick to the same drives for the same array.

Ah I see Jlryan thanks for the info

Hi Captain, , after seeing your advice I feel that I should just go for the original ones instead of the red pro. Thanks for the information! Furthermore, I do not wish to have any data corruption or drive dropouts with the fact that most of my precious files are permanently saved to my NAS.

You are welcome if you value your files, I would consider storing them in two separate places just to be sure they are safe if something happens with the whole enclosure (power surge, physical damage, etc.). Having a backup is always a good idea, especially if the data is valuable.

WD Red should give you pretty good speeds and should be enough for what you need them for.
