Indeed, it's crazy how they've all merged and bought each other, and we're basically left with two big players, plus Toshiba on the sidelines.
I had a WD Blue drive in about 2006 that was OK, served me well for a year or two. When I was building day in/day out we used Seagate and a few Samsung drives, I liked the Samsung drives so I bought quite a lot back then, had one fail but it was taken out by a PSU. The rest are still going strong. When Seagate had some production issues, or we had trouble getting stock, I forget which...we switched to WD drives in builds and the failure rate was incredible. We went from maybe 1 a week DOA, to 10 or 15, plus some with weird incompatibility issues. These were the Blue drives, WD5000AAKS and AAKX when they switched over to maki9ng pointless SATA3 HDDs. Very strange because it wasn't a well publicised thing, I had always been under the impression that there wasn't much in it in terms of reliability and that's what we saw, right up until we actually had to depend on WD. Never bought another WD product since, but then I haven't bought another HDD since I bought all those Samsungs either, now I just have the one 2TB left in a USB3 caddy and I have SSDs for everything else.
