Just FYI WD switched the drives in these enclosures with the new SKU. There have been some reports about air filled drives and other weird complications.

So you saying by the time I get them from Amazon they are going to be SMR and Binder from futurama has corrupted it with a night out on the town?

I got 3/3 EMFZs which are same as the last sale from Amazon. It was free international shipping, spot rate FX conversion and arrived in 4 days. Should have bought more with the second account. Not sure why I am ever hesitating with Amazon.

I got drives from both Amazon and Best Buy on this deal. The Easystore drives from Best Buy are WD120EDAZ-11F3RA0 (R/N: US7SAM120) and the Elements drives from Amazon are WD120EMFZ-11A6JA0 (R/N: US7SAP140).

Looks like they are both Helium filled drives.

Would be interested in what the specs say on the box do they have any difference in rpm or buffer?

They're both ostensibly 5400 rpm and 256MB buffer. Smart data for the two drives is nearly identical (the WD120EDAZ is not in the smart database, the other drive is). They even have the same firmware 81.00A81.

Edit: SO, I just did some more research and it appears that the WD120EMFZ with R/N: US7SAP140 may actually be the 14TB drive with the 12TB firmware installed. The 14TB drive is 7200 rpm and has a 512MB buffer. The manual link I posted above for the Ultrastar-DC-530 says as much. The Amazon spec sheet says the 12TB drive weighs in at 0.87 kg and the 14TB drive is 0.90 kg. I'll update once I've weighed them.

Here is a reddit thread with more information on this. Going through various forum posts, it looks like a lot of the WD 8TB drives documented as 5400 rpm are actually 7200 rpm. This leads me to believe that these 12TB drives are also spinning at 7200 rpm. Guess more sleuthing is in order..

I used to have a ton of both EMAZs and EMFZs. They are 5400rpm but with 512MB cache. They read/write faster than the EMAZs when I did surface tests. The EMFZs have PWDIS enabled. I got rid of the EMFZs when I upgraded the server drives to 14TB and kept the EMAZs for my desktop because I didn't like the separate power cable.

I haven't had any chance with EDAZs but I believe they used to be in the MyBooks which means they don't have TLER and have some sort of self encryption. All in all, it's probably my last round messing with the 12TBs. The EMAZs are my preferred drive and it seems to be a roll between EMFZ and EDAZ these days.
