Summary: I bought this drive to put in an enclosure for massive storage of course. The drive worked for a total of 3 hours. The drive ran super hot out of the case and in the case, I had to go so far as to place a freezer bag of sea salt, ice and water to cool the drive down while I was using it.
Summary: I purchased one of these for an internal back-up drive for a friend's computer. I'm a believer that internal back-ups make a lot more sense than an external drive for multiple reasons that include faster transfer speeds over SATA than USB 2.0, less wear and tear on the drive, etc... This drive did the job until about a month ago when it developed the all too common 'clicks-of-immanent-death.
Summary: I put four of these drives in my Mac Pro. Two of them weren't even be visible for formatting in Disk Utility and had to be replaced. The ones I have gotten working have been working continuously just fine.
Summary: The drive is wonderfully large, fast, and so far, very reliable. However, it can, at times, be extremely noisy as it seeks and writes. Despite being placed in an insulated enclosure, I can hear it working in the next room. I am using it as an external DVR drive and thus the noise is often irritating.
This is a great Terabyte drive, but note potential compatibility issues
18 December 2007
Summary: This is a great Terabyte disk, but note that the 7K1000 has documented compatibility issues with some early first generation SATA controllers. I hit this on a VIA 8237 controller. Hitachi note issues with the VIA 8237A chipset, Marvell Gen 1 series and the Sierra Logic SR-1216 chipset, but there may be others. Unfortunately Hitachi don't provide any workarounds.
