Looks like there is a new 6 TB WD Red replacing older WD60EFRX.
Anyone used it? Is it still not helium?

FWIW, the WD80EFAX is a rebranded HGST helium model. It reports a speed of 5400 RPM via the ATA Identify Device command, but may actually be spinning at 7200 RPM.

Here is a HD Tune read benchmark for a WD100EFAX:

Note that the width of the access time graph is about 8ms which is the max rotational latency of a 7200 RPM drive. However, WD's spec sheet states that the drive's performance is "5400 RPM class".

Once again, the WWN on the label belongs to HGST (5000CCA...):
