Imperial, obviously: F(reedom)T(ons) and fractions thereof. 1FT is the amount of data that it takes to store the entire King James edition of the New Testament and the Bill of Rights as a PDF.

1 floppy = 1.44 MO
1 CD = 700 MO
1 DVD = 4,7 GO
1 HD DVD = 15 GO
1 Blu-Ray = 25 GO

Those are units of discrete quantity, so couple, dozen, score, gross, grand, etc.: https://en.wikipedia.org/wiki/Non-numerical_words_for_quantities

Station wagon full of tapes

A bit in Freedom units is 2 metric bits because it wouldn't be freedom units without unnecessary confusion. A metric bit is equivalent to a freedom unit lil'bit, because it's smaller than a bit. A bite (no relation to a byte) is 25 lil'bits because saying 25 ones and zeros outload is a mouthful. A hot dog is 4.2 bites or 105 lil'bits because that's how many bites it takes me to eat a hot dog. A hamburger is 6.4 bites because it takes more bites to eat. A double with cheese is 7.8 bites. A whole hog is 233 hot dogs. A stampede is 23146 hamburgers.

The Indians use Crore and Lakh

As all your other measurements are based on the subjective measures of random people, I'd suggest using the amount of digits of pi a senior can remember in the time a new school shooting happens as a base, like a Bit. Then just multiply by a random amount for bigger sizes and prefix the name with random presidents names.

• A nugget: 1 bit
• A tendy: 1 byte
• A hot dog : 1 kb
• A hamburger: 1 mb
• A KFC bucket: 1 gb

1TB can be Recommended Chrome Ram?

Increments of 700 MB. As laid down by the wizards of usenet: 1CD, 2CD, 3CD, etc.

And then extending that idea, 1.44 MB, 4.7 GB, and 50 GB units.

A disk is 1,510,294 bytes - because it's 1.44 American megabytes, and a kilobyte is 1024 bytes, god dammit. They're binary. A CD (or "disc") is 486 disks. A DVD5 is 6 CDs, because a DVD9 only holds 12. A BDRXL is 24 DVD5s.

From there we have to defer to the other kind of "elders of the internet" and say a "terabit" is exactly 10 BDRXLs, because my dad absolutely refuses to use the word "terabyte." It's decimalized from there on out. Which sounds great until you realize an American terabit is 5.7% more than asinine SI "hard drive manufacturer" terabytes, but only 98% of a proper binary figure given the even dumber name "tebibyte."

Power of Two

1GB is 29.8975 pots

1MB is 19.9315 pots

I'm surprised there aren't more suggestions which use intentionally-similar abbreviations. The American customary system is rich with abbreviations which are deceptively similar, and I think the American computer memory units should match; confusion is the name of the game. Some examples from existing units:

• millimeter (mm) vs thou (mil)
• meter (m) vs mile (mi)
• kilo (k) vs grand (G)
• kilonewtons (kN) vs knots (kn)
• statute mile (m/sm) vs survey mile (mi) vs nautical mile (NM/nmi) vs nanometer (nm)
• foot (ft) vs fathom (ftm)
• chain (ch) vs Switzerland (ch)
• teaspoon (tsp) vs tablespoon (tbsp)
• ounce (oz) vs fluid ounce (fl oz) vs troy ounce (ozt) vs Australia (Ozzie)
• pint (pt) vs point (pt)
• grain (gr) vs gram (g)
• Kelvin (K) vs Rankine (R; aka "Kelvin for Americans")
• short ton (t) vs long ton (???) vs metric tonne (t) vs refrigeration ton (TR)
