For an older server (sandy/ivy generation) that has a SAS2 backplane I've added a LSI2008-based card (flashed to IT-mode), but procuring drives from that era is getting harder. There are plenty of SAS3 drives available though, new and used. So the question is: which SAS3 drives are to be avoided? A quick search turned up some Seagate drives as not negotiating properly down to 6Gbit. Any other drives people have had problems with in this kind of scenario?

what do you mean "procuring drives from that era is getting harder" ? they are all over ebay.com and other places?
i've never had issues with HGST drives, SAS-3 or otherwise. and since WD's enterprise stuff is now essentially what use to be HGST, those are usually good too. for HDDs, there are really only 3 players now, WD/HGST, Seagate, and Toshiba. Toshiba's 3.5" products are basically HGST too... so really, the only stuff to avoid is Seagate. But, only *some* Seagate 3.5" SAS-3 HDDs have the problem you mention, not all of them; probably the earlier models.
