The First Terabyte Hard Drive Reviewed
mikemuch writes "ExtremeTech has a review and benchmarks of the Hitachi Deskstar 7K1000 1TB Hard Drive, which ushers in the terabyte age. It performs well on HDTach and PCMark benchmarks, though not as speedily as professional-grade drives. It could be just the ticket for digital media junkies. 'One of the first issues to note is that you may not see an actual one terabyte capacity on your system. First, the formatted capacity is always less than the raw space available on the drive. Directory information and formatting data always take up some space. Second, the hard drive industry's definition of a megabyte differs from the rest of the PC business. One megabyte of hard drive space is 1,000,000 bytes: 10^6 bytes. Operating systems calculate one megabyte as 2^20 bytes, or 1,048,576 bytes. Once installed and set up, Hitachi's 1TB hard drive offers up an actual formatted capacity of about 935GB, as measured by the OS. That's still a lot of space, by anyone's definition.'"

I remember when I paid $150 for a 10meg MFM drive! (poke c800:50 ;)
I remember paying $1000 for my first 1gig drive!
I remember paying $500 for my first 1TB of drive space (6x300gb drives ok 1.8TB unformatted)
I remember paying $350 for my second 1.1TB of drive space (4x320gb Just last week)
I can not wait to get to my first 6TB system! I may have said, many years ago, that I would never fill 1gig, but I know I can fill 6TB It should not take me more than a couple of months.
Man how things have changed!
Then 8mhz, 640k ram and 10megs.
Now 2.4Ghz dual core, 2gig ram, 1.1TB HD
I wonder what we will say in another 16 years.
The Hitach is a 1000mb drive with 5x200gb platters.
The Seagate (due soon) is a 1000mb drive with 4x250gb platters and (iirc) 32mb of cache.
The increased platter density will slightly increase performance and theoretically decrease cost, it'll slightly reduce heat and also power use too.
On top of this Seagate offer a 5 year warranty on all drives (Hitachi may also, sorry not sure) and Seagate used to be one of the quietest available to boot. (although I hear the 7200.10's suck for noise, apparently some kind of patent issue with using low acoustic mode - hope that's sorted?)
Anyhow, what this does mean for us end users is you'll see 2 platter, 500gb drives which weigh less, cost less, run faster and cost substantially less than the 1000mb models, also the glorious 750gb will become a 3 platter model instead of a 4 platter (my personal 'limit' is 3playtters - after that I find it too prone to noise / heat / failure rate)
I'd say we'll see 80$ (rebate) 500gb drives within 3 months and we'll see the 750's at 169$ or something soon(ish)
