Samsung 512GB Toggle-mode NAND SSD  (Source: Samsung)
Mass production to start next month

Samsung has announced a new 512GB SSD that uses Samsung's toggle-mode DDR NAND memory and is aimed at the premium notebook market. The company claims that the SSD is good for random write operations of 250MB/s and random read operations of 220MB/s.

However, outright speed isn't all Samsung is claiming with the new SSD. Samsung's new NAND chips can operate at either 3.3V or 1.8V and according to Samsung, the specially designed low-power controller for its toggle-mode NAND allows a notebook using the new SSD to last an additional hour or longer per charge.

“The highly advanced features and characteristics of our new SSD were obtained as a direct result of an aggressive push for further development of our NAND flash technology, our SSD controller and our supportive SSD firmware,” said Dong-Soo Jun, executive vice president, memory marketing, Samsung Electronics. “Early introduction of this state-of-the-art toggle DDR solution will enable Samsung to play a major role in securing faster market acceptance of the new wave of high-end SSD technology,” he added. 

The SSD is built using 30nm-class 32Gb chips and includes support for 256-bit AES data encryption. The drive also supports streamlined boot time and application access, features that Samsung says increases random performance by a factor of nine compared to traditional HDDs. The Windows 7 TRIM command is of course supported.

Volume production of the 512GB SSD will start next month at an undisclosed price (likely because the drives will mainly be featured in OEM systems).

I am interested until they announce it will cost over 9000 dollars or some other absurdly high amount. I wouldn't mind a large SSD even it it doesn't perform as fast as the current SSD kings.

Performing 9 times faster in terms of random writes than traditional hard drives likely will make it perform similarly to Intel's X25-M drives.

Random writes of 250MB/s would blow any current SSD out of the water. I think this is a typo. This is about 100x faster than hard drives and 5-10x faster than existing SSDs. They need to define random.

The question is how large are the random writes. Random writes of 10MB each might as well be sequential as far as benchmarks are concerned.

Just clicked through to the business wire article. 250/220MB/sec are sequential rates.

Indeed, if true that would be an amazing performance. We won't know what the real world performance is until Anand gets his hands on one of this drives.

What's the speed at the lower voltage rating?

The article is just skimming over the most important part of the announcement, I think. What is "toggle-mode DDR" flash?
At first I thought it would be some type of flash that can freely toggle individual bits, eliminating the need to erase and write to whole large cells of memory at a time. This would be truly revolutionary though, and I am sure it would have gotten much more media coverage.
Right now all that I can find online about it seems to only tout a faster "DDR" transfer rate, and no hint as to what "toggle-mode" refers to. Unfortunately, it might just refer to the potential to toggle between this new DDR transfer and standard backwards compatible transfer type, which I don't find useable or even worth mention. Or it might mean any number of other things, I have no clue.

There's your toggle: the voltage.

That was funny... I hope you were kidding, lol.

The clue is in the acronym DDR (historically double data rate) as to what the toggle is in this context. In DDR fashion, the chip is triggered at the leading and trailing edges of the clock cycle... in other words when the voltage toggles from high to low or low to high.

It has absolutely nothing to do with the voltage spec of the machine.

About Toggle-mode DDR NAND

Toggle-mode NAND is a new, soon-to-be-standardized, high-speed memory solution for consumer electronics that will use a dual-date rate interface to substantially increase read and write performance of NAND Flash memory. An asynchronous technology, Toggle-mode DDR products will perform a dual-edge operation for data input and output, using a bi-directional data strobe to effectively align data, with backward compatibility to legacy NAND for easier migration.

Amanojaku... did someone piss in your Wheaties this morning?

If it can run at 3.3V, or save tons of power and run at 1.8V, why would you ever run at 3.3V? The DT article doesn't say anything about what changes when the toggle-mode NAND is running at the lower voltage. It also doesn't really say how the drive employs this, is it dynamic and load based? Would be nice to not have to dig around for this basic information.

Slight exageration

I would take this claim with a grain of salt. If true, it probably only applies to the power sippingest netbooks with the longest battery life.

I find the claim speculative at best. I don't think these will sell in anything other than perhaps the high end clevo and similar enthusiast machines. Those mchines only run for about an hour on a new fully charged battery as is. The HDD's are, I would think, a relatively small player in system power consumption.

Curious about the toggle

So, switching to low voltage mode gives an extra hour of run time. How does this affect performance? I'm guessing performance will also decrease, otherwise it would make sense to always run in low voltage mode, no?

SSD's are efficient

additional one hour from a 10 hour laptop...
