Conclusion:
Seagate really does have the Steve Austin of hard drives on their hands with the Barracuda 7200.10, as it really is better, stronger, faster. Better in terms of the lower noise, and lower heat production provided in part by the implementation of perpendicular recording technology. Stronger thanks to greater shock tolerance and reliability also provided by perpendicular recording technology. And faster as proven by testing. Native Command Queueing, a 3 Gbps SATA interface, 16MB of cache memory, and yes, perpendicular recording technology all chip on that.
One thing the 6 Million Dollar Man didn't have going for him was being "bigger", which is obviously something the 7200.10 does have. At 750 GB, it is the industry leader in size and 50% larger than its 'little' brother, the 500 GB 7200.9. It may be hard for many to imagine filling this drive, but with a vast collection of digital multimedia files, digital home videos, or other large files, typical drives can fill up fast.
On a side note, one thing worth considering on a drive of this size is how to back it up. No matter how reliable or how long the warranty is, important data should be backed up, as data loss isn't always the fault of the hard drive. But, considering the size of this drive, your options for complete redundancy are rather limited, aren't they?
