I think, but don't know for sure, that they were also helium filled

The first to fail, last october is a 2TB Barracuda ST2000DM006, SN
Z4XAWQ6V, PN 2DM164-302
STFW I see nothing that indicates the Seagate Barracuda ST2000DM006 is
helium filled.
STFW for articles related to helium-filled HDD's, I came across the same
article Thomas found:

Unfortunately, I am not finding a follow-up article that addresses the
closing hypothesis:
My hypothesis is that after normalizing the data so that the helium and
air-filled drives have the same (or similar) usage (Drive Days), the
helium-filled drives we use will continue to have a lower Annualized
Failure Rate versus the air-filled drives we use. I expect this trend to
continue for the next year at least.
But, Backblaze does make their raw data available. So, the analysis
task is waiting for whomever is interested:

I have a pair of HGST HUS726T6TALE6L4 drives (6 TB, helium-filled, CMR)
that I use for near-site and off-site backups in rotation. They are
about 22 months old. Whichever is near-site gets gets heavy usage for
10 to 100 minutes once per week (ZFS replication with deduplication).
So far, no problems.
