New 8TB Parity HDD's Required

[Compass]

Hi,

 

Any 'go to' HDD's at the moment, or all much the same? All of my drives are WD Blue and Greens at present, happy to change brand if need be

 

cheers

Shoot for the drives designed for NAS - best and the most expensive option, but be aware of WD Reds.

At least some of the WD Red drives are built on the SMR tech. Avoid!!!

Instead opt for the WD Red Plus drives if you choose to stay with WD. Those are built on the desirable CMR tech.

All of the Seagate NAS drives are fine (CMR tech).

You can also go with cheaper Non-NAS drives.

In that case the only safe option would be to go with a 10 TB or larger Seagate.

Smaller Seagates are SMR drives.

Just came across a guide write up regarding SMR:

Thanks for that,

 

I can get the Ultrastar 8TB DC HC320(0B36404) for a not bad price, thoughts?

It should be fine as long as you get the one without a power disable feature.

The part number indicates it doesn't have one.

 

It seems some vendors might be selling old stock,  with a suspect handling/storage history and maybe even mixing part numbers.
