Good price, but it is SMR, so make sure your use case aligns with that.

What kind of use case is suggested?

AFAIK, data storage where you don't have to re-write often.

If my sanity has to go, it is my job to keep its absence to myself.

What most consumers use these drives for, either storing backups (occasional writes) or storing media library (occasional writes).

It's only if you are writing large amounts of data frequently that the limitations of SMR will hit you hard.

Oh, and certainly these are not to be used in RAID arrays, using them singularly in a NAS (without RAID) is fine as long as write volume isn't high and frequent.

I didn't know this. Thanks for sharing.

So if you're doing a lot of writing (backing up data) like imaging your drive, these SMR drives are not recommended?

How does a consumer know if a hard drive is SMR or not? I see portable drives all the time and never once stopped to think what kind of hard drive it is.

If you are doing alot of writing, but not doing it frequently, then SMR drives are fine as long as you understand the write performance might only be 20-30MB/s. Backup up data is generally something done unattended (you're not waiting for it to complete), so SMR drives are perfect for that (as long as you aren't producing 100s of GBs of data a day for backup.

Hehe, THERE is the big problem, manufacturers are VERY cagey about this, making it damn hard sometimes to figure out.

WDs Blue and Red NAS drives are MOSTLY SMR. Their Red NAS Plus drives are all CMR.

Seagate Compute drives are I think all SMR, Compute Plus and Iron Wolf are CMR (I think).

It's best to check the specific drive model number to be sure.

Thank you again. Where can one find based on the model number if the drive is SMR or CMR? Using the drive listed in this thread, there's no mention:

I err on the side of caution, if it doesn't say, I assume it's SMR.

The model number is on the listing, it's SMR:

Thanks. The notes are confusing for the chart. It says" ?, EZRZ is CMR"

Right, but again, the model, as specified in the listing is EZAZ, not EZRZ, so it's SMR.

The reason they have that comment is because both drives basically look identical, they are both labeled WD Blue:

https://www.amazon.com/Western-Digital- ... TVCHH?th=1

https://www.newegg.com/blue-wd40ezrz-4t ... 6822235011

This is why people are so pissed.

SMR tech is fine, it brings down the prices of drives for people who the performance impacts of SMR aren't an issue (or they are willing to put up with).

The problem is the manufacturers made it basically impossible at first to tell which drive had, and even now most listings don't specify what tech is used. It's complete BS.
