A couple weeks ago my hard drive failed, it was a WD Blue. I found this out when I took it to a local UBreakIFix, and asked them to diagnose it, they told me that the Blue was well known for failing, and that I should get a Black. I ordered one and it arrived a few days later. After installing the WD Black, and reinstalling windows I started to redownload all my most used programs, the first ones being Google Chrome, ESET, and Steam. but as I was downloading Steam, I noticed it was being rather slow, and I checked my internet. I have AT&T U-Verse, and I use an ethernet cord, that runs directly from the modem to my PC. I normally get test results of up to about 950 Mbps down/up on speedtest.net. But when I checked more recently I was getting only 4 Mbps down and the usual 950 Mbps up. I'm wondering if it's just my new hard drive, or if something else could have gone wrong? Please respond, and thank you in advance to anyone who does.
