Sorry, but I did not learn much from the link because opinions there seem divided about 50:50 as to whether data increases the weight of the HDD or not.

One guy said he left his laptop downloading stuff, and returned to find just a hole in the floor. But others spout mystic nonsense about magnetic particles changing orientation - can you belive that? ... who knows? Confused

Wow, you mean if I upload enough stuff and hold on tight I will fly? Awesome.

Thankfully all my data is on floppy disk so my computer is cruising at 1200 ft Laughing Laughing

Surely it also depends on the type of data too? Heavy Metal MP3s are bound to weigh more than light entertainment, and big endian data has to be more massive.

Quantum hard drives presumably weigh more as they are in more than one place at the same time...

No, they weigh less as they're on more place then one and the weight of the data they hold is distributed evenly between those places. Otherwise their data weighs in at one place and is weightless elsewhere. That's impossible!

That's heavy man, real heavy.

Oh and I have a Quantum HDD in the loft. Very light weight only 50 MB

Come to think of it, more storage makes it lighter! Remember the days of 128kB RAM, harddrives of 512MB and 10" VGA CRT monitors for your quite unwieldy 486 box? Compare to the latest tablets with 128GB of storage and 512MB of RAM, the tablet is a featherweight! So, more data makes a device lighter Shocked

Then just think of all the data on the net no wonder is called the Clould.

Not that either. A quantum drive exists in a superposition of different possible weights, and it does not have a real weight until you collapse it (I have used a lump hammer for this). Even then its weight will be arbitrary within a range of probable values.

And if you entangle two quantum drives together (easy once the cables are attached), then writing data to one also writes the data to the other, a great software-free backup regime.

The only downside is you have to buy two HDs, then smash one flat before you can read your data back from the other.

You've all missed the point that Quantum drives of any significant size don't exist at all. The company stopped making hard drives in 2001 Razz

LOL! Keep the comments comin' guys...

IMO, a hard drive's weight is continually dynamic due to constant thrashing of the I-O, (iron-Oxide)...

The Earth's magnetic field plays its part too; like poles repel and opposing poles attract - basic physics...

You mean all their drives have had definite weights since it collapsed? Very Happy
