News CompactFlash grows to 144PB

http://www.bit-tech.net/news/hardware/2010/02/23/compactflash-grows-to-144pb/1

The CompactFlash Association has unveiled the latest version of the memory card standard, which increases the addressable storage space to 144 petabytes.

 

A somewhat misleading article title perhaps, given that it's only the specification that allows for 144PB...

Though any advances in small form factor storage technologies are more than welcome - mechanical, flash or otherwise.

 

That's a big understatement - the state of the art is still a loooong way from cramming even a single TERABYTE into that form factor, so a PB is in the realms of fantasy for the foreseeable future.

 

they did say theoretical max so we will never hit that high no matter what people say
we may get clsoe but not that much

 

Agreed, huge theoretical limits are brilliant as they tend never to create real world bottlenecks requiring changes to standards. I was more poking fun at the uncharacteristically sensationalist headline from BT.

 

144PB is alot of info, but the Isolinear optical chips can hold a maximum capacity of 2.15 kiloquads of data! Eat that CF5.0!!

 

WAT.

 

its over 9000!!!!

 

Much more impressed by the increased data rate. FAR more useful!

 

anyway i dont know about you but at currrent rates wouldnt this be aimed at buissness and corporations becasue there is no way you can download that much data from internet from current speed (20mb/s average max 1gb)

or 578 constant days downloading lol

 

Yet another article that confuses the confused regarding base 2 over base 10.

i.e. 1 kilobyte is 1000 bytes, 1 kibibyte is 1024 bytes (base 10 vs base 2)

Thus:

1 Petabyte (PB) is 1000 terabytes (TB)
1 Pebibyte (PiB) is 1024 tebibytes (TiB)

So 144PB is 144000 TB, however 144 PiB is 147456 TiB.

144PB is actually 130967 TiB. Come on bit-tech, simple mathematics!

 

I see this being more of a niche product. The physical size of the media makes it less and less suitable to modern thin/small devices.

 

I'm personally more impressed by the fuglyness of the CFA logo !

yewww


Got to love CF though. There used to be how many formats and now all we can all feel safe knowing whatever we buy will require CF

 

I thought current cards would hold up to 650GB?

 

article states a "new connector"

backwards compatible?

 

just have to understand binary.. 8 bits to a byte- those 8 bits alone can count up to 256 (so any byte can represent any number between 0-255).. each bit only has 2 values- on or off

collectively- you can get a better understanding if you think of bits as light switches

all 8 bits in a byte:

bit #1 = 1
bit #2 = 2
bit #3 = 4
bit #4 = 8
bit #5 = 16
bit #6 = 32
bit #7 = 64
bit #8 = 128

now like mentioned each bit only has 2 values- like a light switch on or off, 0 or 1.. so if they are all 0, the byte is = 0

now let's flip some switches bitches hehe.. say we turn on bit 7 and 5.. 64+16 = 80

now flip on bit 1.. 64+16+1 = 81

flip them all on and you have 255 (256 total if you include 0).. you can see using these 'switches' we can assign any number between 0 and 255 to 8 bits.. 9 bits, just one more bit than we have now.. we can now count up to 512 (bit #9 = 256).. 10 bits 1024.. ect..

that might be a little easier to understand for people who are trying to learn the basics.. why we have 1024 bits in a kilobit.. 1024 bytes in a kilobyte.. ect..

I actually taught this stuff in school to the rest of the class, the instructor was trying too hard

 

Strange...

2^48 = 281.474.976.710.656
2^47 = 140.737.488.355.328

 

ah yeah your right, just ran the numbers.. 48 bits comes out to 256 petabytes- it's the spec limit guess

 

However. Storage manufacturers have typically used base 10 when it comes to things like hard drives, which is why your 1TB hard drive doesn't actually have 1TB of usable storage space.
