Samsung has started manufacturing absurdly fast PCIe (M.2) SSD

Samsung has started manufacturing a PCIe (M.2) SSD that pulls off a rare trick -- it'll be the fastest drive your laptop has ever seen, while consuming almost no power in standby mode. The new SM951 SSD succeeds the Korean company's XP941, a drive that can already read data at a mind-melting 1.4 gigabytes per second (GB/s) clip. On newer laptops or desktops, its successor will shame that with 2.15 GB/s read and 1.55 GB/s write speeds (on PCIe Gen 3 tech) using new 10-nanometer-class MLC flash tech. It also sips 50 percent less power and only consumes a negligible two milliwatts in standby mode. The SSDs will come in 128, 256 and 512GB sizes, but only to major laptop and workstation manufacturers to start with. If it follows the XP941's footsteps, however, you'll be able to supercharge your own laptop later on.

This is ridiculous. No one will ever need read/write speeds that fast.
Uses almost no power in stand by mode? Who would need that. We don't power our laptops with a hand crank.
There goes Samsung screwing their customers again. I'm sure everyone that bought a Samsung SSD this past year are pissed. How dare samsung sell them a product when they know they have cutting edge tech coming out so soon.

I eagerly await the day I can put 2, 1TB versions of these in my desktop in a Raid 0

Seriously though, will the speed of these things be bottlenecked by other computer components?

At some point, probably.
That is the computer business. Always trying to improve the bottleneck.

No. I/O is the bottleneck in any modern computer system. The specific i/o bottleneck now is the NAND itself and the controllers. Prior to this, SATA III SSDs were reaching the point where its own interface bandwidth was becoming the bottleneck, hence the move to PCIe and SATA Express. Working as buffer cache, scratch disk, pagefile, and system drive, the SSD itself is still the system bottleneck.
EDIT: I should caveat that by saying it won't make your CPU or GPU render/encode any faster, so it totally depends on the task being performed, but in general it's the latency of i/o that remains the system bottleneck, hence the existence of RAM and why RAM continues to get faster alongside storage (system memory and storage are soon going to converge).

Will be amazing, eventually.

NAND as in the NAND gates? They're made almost entirely with transistors. I was under the impression that memory was a bunch of flip flops, which are also transistor heavy.
But if logic gates are bottlenecking computers, I'd imagine there will have to be a gamechanging breakthrough to speed them up without simply adding more gates etc...

Sorry, NAND flash memory. They have finite data rates even with the best controllers because they are just made up of floating gate transistors (not an engineer, so don't ask me to explain how those work without googling). Yes, that's correct that just adding more gates would speed them up, assuming the use of an appropriate controller -- but NAND flash chips are subject to the same lithography limits as other chips.

Gotcha. Thanks.
I'm about to be one and have never heard of them myself. Bored and curious so I'll look them up.

It's basically a MOSFET that keeps its state when power is removed.
