Does anyone have experience with these hard drives?

I'm about to buy a new internal hard drive for my macbook pro 13" early 2011 model, and I've found two reasonably priced drives. I'm saving up for an SSD. but right now I can only afford a regular 1TB drive. Has anyone used these drives? how do they perform?

1. WD black mobile HD, 1 TB, 7200 RPM, 32MB Cache, SATA 6.0Gb/s

2. HGST travelstar H2IK10003272SN High performance mobile drive, 1 TB, 7200 RPM, 32MB Cache, SATA 6.0Gb/s

You can find a large number of user reviews for both drives on Amazon's Web site.

Sadly, it will be three or four years from now before anyone can tell you authoritatively how good either of these drives are. Reviews only tell you how well they have worked for folks for the few months that they have had them. it will be three or four years before we know if today's batch of hard drives turns out to be exceptionally reliable, or exceptionally unreliable. And it will require that someone do a study.

There are studies that show that HGST drives tend to be exceptional reliable, and that WD Black drives tend to be very reliable, but those studies are based on drives purchased as much as five or six years ago, and you can't infer from those studies how reliable these drives might be. Modern HGST drives aren't even likely to have been built in the same factory, or even the same country, as HGST drives from six years ago.

The best that you can do is purchase an internal hard drive mechanism that isn't known for a huge number of DOA's, and then make sure that you always have a backup of your data if your data is important to you.

Let me ask you a question, do you need your optical drive? In 2012, when I got my 2011 MBP, I replaced the internal 500gb HDD with a 240gb SSD and moved the original drive to the optical drive bay. They have adapters for that, then I got an external USB enclosure for the optical drive. Just a suggestion.
