Western Digital got most of HGST - however HGST's 3.5in drive business was sold to Toshiba. The HGST branding went to WD.

I believe hese new HGST drives are WDs.

The HGST drives in the older backblaze stats (which showed good reliability) continue to be manufactured by/evolved into Toshibas. There are several HGST model numbers that remained in Toshiba's lineup.
