SanDisk Releases 512GB SD Card
Lucas123 writes: SanDisk has announced the world's highest capacity SD card, a 512GB model that represents a 1,000-fold increase over the company's first 512MB card that it shipped a decade ago. The SanDisk Extreme PRO SDXC UHS-I memory card has a max read/write rate of 95MB/s and 90MB/s, respectively. The card is rated to function in temperatures from -13 to 185 degrees Fahrenheit. The 512GB model retails for $800. The card also comes in 128GB and 256GB capacities.
Yes, apparently it is too much to ask that people be correct these days.
The summary clearly states that 512GB of memory is 1000 times more than 512MB of memory, which is patently false. If you're making comparisons, you don't make absolute statements like this. You use qualifying words like "about 1000 times" or "approximately 1000 times" to let the reader know you do not mean to be precise.
One arbitrary roller-coaster is as good as another.
A Pirate and a Puritan look the same on a balance sheet.
Choosing water's freezing and boiling points is ALSO fairly arbitrary.
How is 640kb of ram working out for you?
No, a "traditional" GB is the one that was defined way before computer scientists got their hands on it –1000. The 1024 "definition" is actually simply a bug. Engineers working on early machines had a choice – take a bug that pretty much no one would notice on an early machine (because files over 1kB were very rare, much less ones over 1MB), or take a massive perf hit. It takes a long time to compute the size of 20 files when a division by 1000 takes 300 odd cycles on a 10kHz machine. It doesn't take such a long time when a right shift 10 takes 1 cycle.
Bottom line, early engineers decided a known bug was better than the enormous perf hit of getting it correct. That doesn't mean that what they did is now correct. It means it remains a bug in some OSes.
I have an irrational desire to slap the people who thought inventing GiB was a good idea. I hope it's forgotten eventually. All the justifications for it were (and still are) bullshit -everyone knew what HD vendors were doing and no one who mattered was confused. That's still true , but now I have to explain to people that no, it's not a speech impediment...
Samsung took back my unlocked bootloader because Google wants me to rent movies. They're both evil.
