What salesperson, from what (re)seller, said that?
WD told me that the EURX is still being produced, and is NOT at the end of life point, and far from it. I was also told by WD that the WD Purple PURX is NOT designed for use on non-RAID controllers, or in any PVR/DVR that only has one drive, without the controller supporting RAID. No TiVo on the market has a RAID controller, making it an unsupported use of the drive, which WD will not provide any support for, should you seek support from WD (but getting a warranty replacement is not an issue, as WD is not enforcing their own policies, at this time
So far, only Newegg's automatic webpage notice is falsely flagging it as the AV-GP EURX "newer model", and a few marketplace sellers have assumed that is true.
Weaknees is using them in their upgraded TiVos, and upgrade drive kits. But, I suspect they might have found a way to disable the problematic TLER RAID function.
If I were forced to pick a drive other than an AV-GP EURX drive, I'd pick the WD Red (which I use), with over 2x the TB/yr rating (and the same TLER issues with non-RAID controllers). The Purple PURX is only rated 60TB/yr workload (long enough to live through WK 180-day warranty, and at a higher profit margin).
