We should expect to see 1TB hard disk drive products within 6 months

Seagate Technology has just released information to DailyTech with regard to the company's upcoming highest capacity hard disk drive to date. At 1TB, if no other hard disk drive manufacturer can catch up, Seagate will have the highest capacity hard drive product to market first.

The 1TB hard disk drive will be based on perpendicular recording technology which packs bits tighter onto the magnetic platter by positioning them perpendicular to the platter as opposed to linear recording which positions bits horizontally. The perpendicular recording technology, which has been in use by Seagate and its platter supplier for over a year now, will be put to the test as Seagate states the 1TB product will implement fewer platters and heads to improve the performance of the drive.

In a statement to DailyTech earlier today, the company claimed:
Seagate’s 1TB hard drive will be our second generation 3.5-inch hard drive to feature capacity-boosting perpendicular recording technology, and it will use fewer heads and discs than similar-capacity products we expect to see from our competitors. It is clear that fewer heads and discs, along with our proven perpendicular technology, can increase drive reliability, and also reduce operating temperatures, power consumption, noise, and weight.
It is confirmed now that we should expect a 1TB Barracuda from Seagate Technology to hit the market in full force sometime in the first half of this calendar year.   Seagate was also the first company to announce a 750GB hard drive last year.  No company has since announced a drive with 750GB or greater capacity.

Hard-drive manufacturers (and also optical disk manufacturers since DVD days) are sticking with the decimal prefixes and it would be disadvantageous for any of them to switch to using the binary prefixes, so we'll just have to get used to converting them correctly.

One slight point is that 1TB / 1000GB (decimal) is actually only about 931GB (binary).

It'll be even more fun once drives are large enough for their binary size in Windows and other OSs to be reported as TB rather than GB as there'll be a further discrepancy in sizes. A 2TB drive would actually appear as about 1.82TB (nearly 10% less than the binary size!)

There is nothing wrong with binary prefixes, but windows uses the wrong name, it should be 931 GiB, or 1.82 TiB 1000 GB = 931 GiB, 1000 GB is not the same as 932 GB.

There's no particular reason I can think of why a disk drive needs to be described using binary sorts of sizing. Memory yes, because it's accessed using a binary address. But drives aren't addressed in that manner and could just as well be "regular" sorts of kilo/mega/giga.

It's kind of like flash where NOR-flash is necessarily binary-addressed, while NAND-flash (although are still described by binary sorts of sizing) are addressed through file-system sorts of attributes like hard drives (and historically had lots of bad-blocks and the like which is why the actual sizes weren't what was written on them -- and in fact some NAND-flash modules even now say this very thing in the fine print, especially the cheaper brands).

(NAND flash is the kind in digital cameras, iPods, etc. and are file-system devices while NOR-flash act (roughly) as non-volatile RAM memory)
