Samsung Produces World's Fastest Flash Memory for Smartphones

Memory features 140 MB/s reads, 50 MB/s writes
budget personal computer (PC) solid state drives
(SSDs) offer read speeds of up to 230 MB/s and write speeds of up to 190 MB/s.
can record speeds of up to 492MB/sec for sequential reads and 518MB/sec for sequential writes.
But the NAND memory used in tablets and smartphones has been stuck in the slow lane, largely due to power and space (form factor) constraints. That's why the new
Samsung Embedded Multimedia Card (eMMC) Pro Class 1500
is an exciting development, despite speeds that would seem pedestrian by PC standards.
Samsung Electronics Comp., Ltd. (
) is building the new NAND memory on its proprietary
20 nm process node
. It just began "volume production" of 16-, 32- and 64-gigabyte (GB) density modules for "smartphones, tablets, and other mobile devices."
The eMMC modules off sequential reads of 140 MB/s and sequential writes of up to 50 MB/s. For random reads/writes it can handle 3500/1500 IOPS (inputs and outputs per second), which Samsung claims is four times as fast as previous solutions.
The modules use 2, 4, and 8 8-gigabyte dies stacked on top of each other. The package is extremely compact -- even the 8-die package is only 1.2 mm thick and weighs a mere 0.6 grams.
Samsung fills in some technical details, writing:
Samsung eMMC Pro Class 1500 is the first to support the latest
JEDEC e-MMC v4.5
specification that standardizes more features to improve performance, efficiency, security, and reliability such as: a SDR-200 Interface (200MHz, 200MB/s Max Bandwidth), cache handling, dynamic handling, file sanitizing, and power-off notification.
The new NAND are the first major refresh to Samsung's storage line since it introduced "64GB eMMC in January of 2010 using 30nm-class 32Gb NAND flash components."
Ironically some of these metaphorically hot new chips may wind up in arch-rival Apple, Inc.'s (
) new iPhones and iPads, despite the fact that Apple is trying to sue Samsung's popular, industry-leading smartphones
off the market
In a recent interview
Samsung product chief Kevin Packingham bemoaned this relationship, commenting, "[At] times... I’m absolutely appalled that we sell what I consider to be the most innovative, most secret parts... of our products to... Apple [or anybody]."
But he said that the chip-making unit tells him, "Look, that’s none of your business. You go make your mobile phones and if you’d like to use our components, that’d be great."

Vista actually took a long time because they had to rewrite a large chunk of the codebase due to various reasons, but necessarily because they took their time. In addition, Vista didn't really suck, the drivers for Vista sucked.
Most of the crashes in the OS were video driver issues by nvidia, ati, and intel (
In addition, the shitty performance was mostly due to selling hardware underrated for the complexity of the OS. In fact, Windows 7 is almost identical to Vista under the hood with a few improvements, but nobody complains about that do they? Probably because the lowest end desktop CPU you can buy these days will pretty much chug anything you want it to do.

Two small fixes - sorry
1- It decided to combine my ending ). into the URL, so here it is again with an actual working link:
2)- It should read "but
necessarily because they took their time"
