What is the capacity of the biggest hard drive available today?

Answer 1

Currently, commercial computers (sold at hardware stores to normal customers) mostly contain hard disk that have a capacity around 500 gb, for desktops, and 120gb for notebooks. The 500gb could sometimes even be 1TB for desktops

IMPROVED:

As of this response (7/21/2010) the largest HDDs in production are 1.5 TB for 3.5" and 4.5 TB for external/array packages. However technology is in prototype with up to 4.5 TB 3.5" available relatively soon (within a couple years).

The largest memory modules in commercial production are 16 GB DDR2 sticks, though only 4GB sticks are common for end-users.

The largest SSDs available are currently around the 500 GB mark, and rediculously expensive.

The largest EEPROMs are 64 MB single-chip

The largest SRAM caches are 8 MB single-chip

The highest commercial density storage is Blu-Ray with 25 GB per layer (50 GB dual-layer), but with HVDs and PSDs on the way.

The largest tape drive is an astounding 12 TB 14.5" tape from IBM

The largest Flash single-chip module is 512 MB (of course much bigger can be made combining chips, as almost all flash devices do)

Largest SD card is 64 GB

Largest single-CPU cache combination structure is 12,928 KB

Largest CPU register bank is 4096 bits

Largest HDD buffer is 32 MB

Largest sequential tape memory is 1 GB

Largest video card is 8 GB

And that's all I know for the moment. (Whew, that took some research!)

Answer 4

There is no upper limit on data storage on a computer, but specific computer architectures or implementations will have definite limits. As improvements have been made in computer design these limits have grown exponentially and are expected to continue to grow.

When I started in computing in the 1970s large mainframe computers often were limited to less than 32KB of RAM (magnetic core memory) and used 2MB multiplatter removable harddisks and these computers cost a couple million dollars; now you can buy a laptop computer with 16GB of RAM and 4TB of internal harddisk for a couple thousand dollars. These numbers will continue changing: more memory, more storage, lower prices for the foreseeable future.
