Seagate Launches Industry-First 1.5TB Desktop Drive, Destroys Storage Worldstone

Manufacturer's have a history of re-defining measures for marketing purposes. When's the last time you bought 2x4 lumber that actually measured 2"x4"? Remember those 500MB tape drives that had a 250MB physical capacity? An asterisk would lead to the small print and a statement that the capacity assumed a 2-to-1 compression ratio: you're own mileage may vary. 

Disk manufacture's didn't start using the decimal SI system until the capacity of hard disks grew large enough to make the shift in terminology significant. It's sorta like cereal companies that regularly tout lower prices or more servings; in reality talk meant to cover smaller and/or partially empty boxes, less product, and smaller defined portions.

In the case of hard drive capacities, the OS providers, Microsoft, Apple, the Linux community, etc., need to get with the program. Their use of KB, MB, GB and TB is out of step and just doesn't jibe with the Orwellian reality of hard drive capacity new speak.

What's ironic here is that Seagate has had to pass on what is really an excellent marketing opportunity: what in reality is the world's first commercially available consumer 1TB+ hard drive. Assuning they get it to market first!



I remember a point in the closing months of last year where Seagate had an out-of-court settlement because its drives aren't as big as they claim. Granted, it's great that they came out with the first drive beyond the 1TB threshold. But in taking their past practice into consideration - they marked their drives on base 10 instead of base 2, thus stifling the consumer of real space once the drive got mounted - shouldn't we expect it to be 1.25 or 1.3 instead of the promised 1.5?



That's a commonality shared by all the hard drive manufacturers.  So yes, it won't be 1.5 TB on the dot.  Not the way Windows measures terabytes, at least.



Here's a little more light on the subject. Drive vendors count billions (GB) and trillions (TB) the way normal people do: as multiples of 1000. However, operating systems use binary, using multiples of 1024 instead of 1000. That's why Windows and Seagate (or any other drive vendor) don't agree on the capacity when expressed in GB or TB. Windows uses binary GB/TB and Seagate uses decimal GB/TB. However, the actual number of bytes is the same. They're just being divided or multiplied by different number systems to calculate GB or TB ratings.


It's amazing how illogical a business built on binary logic can be.



Terabyte implies decimal.

One terabyte is, as a matter of fact, by decree of the SI (The standards body that makes measurement standards), IEC, and etymologically, one thousand gigabytes which is one thousand megabytes and so on.

Again, terabyte refers to a decial measurement.  The prefix tera is decimal.

The appropriate prefix when referring to a binary measurement is tebi.  One tebibyte is one thousand twenty four gibibytes which is one thousand twenty four mebibytes.  

This is just a case of greedy lawyers bilking companies out of money.



You're correct, but unfortunately the tebi, gibi, and mebi terminology has never been popular. In practical terms, "decimals to the left of me, binary's to the right, here I am, stuck in the middle with you" and everybody else trying to decide how much a "GB" is.
