Pros: Fast, quiet, low vibration. I guess I got one of the "good ones". The box had a big dent in it but the drive was luckily packed pretty well I guess, with the drive wrapped in bubble wrap and packed with foam peanuts. No problems getting the drive recognized and formatted, and its about as fast as it gets for a conventional consumer-level hard drive.
Cons: It took about 20 hours to do a full format using an external USB enclosure. This is not a problem with the drive, just realize that if you aren't doing a quick format (a bad idea the first time you use a drive, in my opinion), it may be a while before the drive is ready to use. Or you can quick format it and hope it doesn't have any problems, if you need it ready sooner, but the saying "hope is not a very good risk management strategy" applies.
Overall Review: These drives are about as good as it gets, especially for backwards compatibility. Once you get above 2GB you end up worrying about partition size and GPT partitions, and then you may have problems moving the drive from system to system without re-formatting from scratch. I needed to transfer about 800GB from one system to another and then plan on using this in my windows home server system, so it was important to me to be able to move it between systems without having to reformat or play games with the partitions. I'm very happy with its performance and as I said above, I guess I got one of the good ones because it is quiet and has pretty low vibration.
Pros: Using as a hotswappable drive in my system. Very quit and running great fast and stable. Like others mentioned this is one hefty drive.
Pros: No problems so far. I've been hammering on this drive for three months now, spooling uncompressed HD footage on and off daily. I have yet to encounter any snags. Noise and heat levels are all well within acceptable levels. The drive is mounted internally in a Mac Pro running Mac OS 10.6.7.
Cons: Not free?
Overall Review: I've come to trust the WD Caviar Black line as production drives. I've found the noise level to be superior to that of the Seagates and performance to be as good as anything I've encountered at this price point.
Pros: Large Cache and storage space
Cons: Slow when using SATA 3, but to be fair, that's expected
Overall Review: My mobo does not have SATA 6Gb so keep that in mind. Right now this drive is just as fast as my 1GB 7200.12. If you do not have a SATA 6 mobo, don't expect anything great. I will update when I update my system.
Asus Rampage Formula (X48), Q9650 @ 4.2, ATI 4890 XFire, custom water cooled full tower system, 8 GB OCZ Flex 1200 DDR2, WD Raptor 150Gb x 2 Raid O, WD Black 2TB, Seagate 1TB 7200.12, Win 7 64
Pros: Extremely fast for the storage size, and the price is pretty hard to beat when you need the most storage possible in a dense environment. Bought because we've got a ton of 1TB Blacks already and they're fantastic and reliable drives. Newegg's support of their customers, as always, is top freaking notch.
Cons: 2 out of 8 were DOA, and 1 just started throwing media errors (which is a sign it's on it's way). Not exactly what I was expecting.
Overall Review: Even with that in mind, the price for the performance is pretty impossible to beat. We built two new Hyper-V hosts in 2U Supermicro cases with 2x8 core Opterons with 4 of these each in a RAID6 tied to a LSI 9260-4i. Running in RAID-6, when they run, they're quite the screamers. I was frankly pretty impressed.. when they run.
Although you've gotta love the LSI controller. Even with two failed drives the array still stayed up, and I was able to migrate to a failover Hyper-V host in < 10 minutes, saturating the gig link between the two.. even in degraded mode.
Pros: Purchased back in August, 2011 for $154.99. From the time of its delivery to me until the time of this posting has been 3407 hours, and according the SMART info, this drive has been running for 3386 of them, leaving only 21 total hours it's been powered down. Flawless operation during that time. Waiting on the price to come down just a bit more before purchasing another.
Cons: None whatsoever.
Overall Review: I also have a 1TB Black, owned for 4943 hours as of this writing, running for 4773 of them. Also flawless operation.
My 320GB Black main drive has an uptime of 22994 hours in 24231 hours of ownership with no faults.
My 1TB and 2TB drives are used for storage for torrents of tv/movies, and are in operation anytime the computer is on. My HDD light effectively never is unlit.
I've always and only owned WD drives, and I've always had APC battery backups on my computers. I've never had a hard drive fault in ~20 years of multiple computer ownership. Whatever your choice of drive manufacturer, make sure you have power protection. Power instability is probably the biggest cause of data corruption.
Pros: I paid $150 for this back in Sept 2011. My kid already killed 2 of the 1Terabyte drives so I bought this to give him room for all the stuff he puts on it. I know its a 6.0Gb/s drive that I put into a 3.0Gb/s MB system but the rating was better for this than the WD 2 Terabyte 3.0Gb/s drive. Its fast and quiet.
Cons: I'd like to buy a couple more but the price has been inflated by vendor fears of shortages.
Pros: Fast for a 7200, Stable, Inexpensive.
Cons: It has moving parts!
Overall Review: I just want to say something about the customer service of western digital. I have(mostly) been using WD hdds since 2000 with a couple others in the mix. I bought a 1 tb black about a 18 months ago. it failed after 4 months(smart warning, no data loss). I went to WD website. Amazingly, warranty process was so simple I could do it. WD did something that surprised me, they replaced the 1 tb with a 1.5 tb. I thought this was a mistake, but of course I kept it. It failed after 2 months. Frustrated and wondering about WD. I went to their website and once again so simple. THEN WD sent me a 2TB black!! Wow! That was no mistake! It's called customer service. This very small gesture is huge for me. I will never use another drive no matter how many fail. It's nice to see a company to go above and beyond. Btw, the 2tb has been going strong! 1 year and counting, not a hitch!
