The energy storage density of the samples was also a few orders of magnitude below that required by an EESU, having storage equivalent to lithium ion batteries.
32.
After exponential growth of hard drive storage density, a single inexpensive hard disk drive has many times the capacity of a CD, and changers have fallen out of use.
33.
IBM has demonstrated storage densities up to 35.3 billion bits, or gigabits, per square inch, and it is now shipping disks with densities of 14.3 gigabits per square inch.
34.
Thus to result in the necessary plasma energy density ( which is found to be a near constant for optimized neutron production ) requires widely differing initial storage density.
35.
To get around the superparamagnetic limit on storage density, some researchers say, it may be possible to use GMR to build microscopic transistors, which would blend silicon and magnetic technologies.
36.
The reason for this transition is the need to continue the trend of increasing storage densities, with perpendicularly oriented media offering a more stable solution for a decreasing bit size.
37.
Memory storage density is the main determinant of cost in most computer memory systems, and due to this flash has evolved into one of the lowest cost solid-state memory devices available.
38.
Moreover, IBM executives said they were particularly excited about the most recent advance because it dramatically pushes back a potential theoretical roadblock to storage density known as the " superparamagnetic effect ."
39.
In the newest drives, as of 2009, low-density parity-check codes ( LDPC ) were supplanting Reed-Solomon; LDPC codes enable performance close to the Shannon Limit and thus provide the highest storage density available.
40.
IBM has demonstrated storage densities up to 35 . 3 billion bits, or gigabits, per square inch, and it is now shipping disks with densities of 14 . 3 gigabits per square inch.
