I am in Canada. In total I paid 705$ after tax, which comes down to $0.0159/GB, which is insane value.
1. Model number is ST22000DM000.
This is a barracuda labeled OEM/ white label drive. this drive is not retailed anywhere and there is no information online available.
I have spoken to seagate rep to try to extract some information about the drives I purchased but received conflicting and questionable information.
At first they gave me EXOS data sheet, then they gave me barracuda (regular) data sheet, but none of the datasheet alligns with the model number. Given that the model number is DM000, it is very highly likely that this is a barracuda regular drive.
2. Rep claimed the following specs:
Cache Size:
256MB Interface: SATA 6Gb/s7200 RPM Helium-filled CMR
3. Personal testing:- This is CMR drive. sustained 230+ Mybte/s write rate for over 10 minutes on 200GB write file test. critical for NAS- This is NOT helium filled - idle temps 56 - 58 degrees C and max went to 61 degrees.
EDIT1: it IS a helium drive after further testing - see edit1. The previous test is in the enclosure.- Detected ERC 7 seconds for both read and write - critical for NAS- firmware EN03 - but shouldn't matter.- unlikely to have vibration sensor.
Personally, I will be keeping and shucking these two drives and putting them into my synology NAS. Unfortunately, it isn't exos or ironwold which is a bummer, but I have a two bay nas and should be still fine. Price is too good.I hope this helps anybody wondering
EDIT1: I spent the entire night further testing these drives after I have shucked them.
1. The initial sustained temperature 56-58 degrees from my testing the drive within its enclosure is not accurate. After shucking and leaving it in the open I ran test on it for 8 hours and it peaked at 47 degrees. This is indeed a helium drive.
2. The initial write speed was 240MB/s and dropped to about 220MB/s after 8 TB. This sorts of speed resemble Ironwolf/ Exos models more than regular Barracuda.
EDIT 1 thoughts: I think this is likely an undercover binned exos/ ironwolf drive, disguised under white
label to discourage shucking.

You've already figured some of this out but I'll just reiterate for anyone else wondering. These are CMR, helium, HAMR drives and should have 512MB cache. There are no DM-SMR (the only type of SMR meant for consumers) or air drives anywhere close to this capacity. All the large (>10TB) Barracuda labeled drives are HAMR. They're based on the same design as some Exos, though which exact one is up for debate.
As long as they're not SMR drives, I think most people will be fine. SMR drives are just terrible and should never have been put in the consumer market.
