Easystores now exclusively ship with WD120EMFZs which require the 3.3v mod, having 512MB cache and are lower binned versions of the 14TBs. The Elements still ship with the WD120EMAZs which don't require the 3.3v mod and come with only 256MB cache. For some reason the EMAZs have a sustained write of ~100MB/s while the EMFZs can go up to ~200MB/s.

Does this mean that EMFZ is a better drive than EMAZ ?
How about mix and matching EMFZ and EMAZ in ZFS ??
Currently my ZFS storage server is running 2x vdev of 6x 12TB EMAZ and I want to expand another 2 vdev soon (10% capacity left)
Should I wait for Elements to get on sale of mix and matching EMFZ and EMAZ is competely fine ?

14TB Easystores are 189GBP at amazon.uk now https://www.amazon.co.uk/gp/product/B07Y3KDVZH/It hurts so much to read what great deals you have over there. Here in Sweden 10TB costs 400 USD. I've paid 2400 USD instead of 1080 USD (if they cost 180) for 6 x 10 TB..
And I can't order them cheap from eBay, the shipping and import charges that eBay add makes it as expensive
Apologies, I may have been mistaken. I have shucked many of these drives for the last few years, been reading multiple forums where members shuck many of these drives and after reading hundreds of comments and threads over the last few years, have never seen anyone report that they have received a shingled drive.
which WD EasyStore drives come with shingled drives? That would really help members understand what they are getting.
thank you

"WD external HDD drives that have SMR (Shingled Magnetic Recording) drive inside, offer TRIM command support"

No. TRIM is for any media where whether a sector holds data makes a difference.
SMR drive is a kind of media where whether a sector holds data makes a difference.

These go on sale frequently and usually only for a few hours at a time.
Keep watching for another sale and you will easily get some.
I dont think there has been any shingled in the Easystores yet. I dont know why this question pops up every time. I guess its Toshiba or Seagate that wants to slow the trend of shucking WD drives.
So I have gotten both flavor of the drives EMAZ and EMFZ and individually benchmarking those drives seems to yield similar result.
I currently have a pool that comprise of 2 vdev with 6x EMAZ for one and 6x EMFZ for another. Performance of the pool is what you would expect from a spinners so it seems ok. I got about 50% utilization right now so maybe as I filled up the drives I will start seeing the shortcoming of the vdev if one of them are SMR drives.
