Samsung 512GB SSD Has Toggle-mode DDR NAND
This is a big, fast SSD. We want it.
SSDs are now hitting sizes that are beginning to make them viable replacements for the magnetic counterparts. Samsung has introduced a new SSD offering in a 512GB configuration – boasting both capacity and speed, utilizing high-performance "toggle-mode" DDR NAND.
"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 new 512GB SSD makes use of a 30 nanometer-class 32 gigabit chip that the company began producing last November. The toggle-mode DDR structure together with the SATA 3.0Gbps interface generates a maximum sequential read speed of 250 MBps and a 220MBps sequential write speed, both of which provide three-fold the performance of a typical hard disk drive.
Samsung says that those speeds could mean that two 4GB DVD movies can be stored in just a minute.
Samsung provides further gains in power efficiency by having developed a low-power controller specifically for toggle-mode DDR NAND. The resulting power throttling capability enables the drive's high-performance levels without any increase in power consumption over a 40nm-class 16Gb NAND-based 256GB SSD. The controller also analyzes frequency of use and preferences of the user to automatically activate a low-power mode that can extend a notebook's battery life for an hour or more (but probably only in best-case-scenarios).
Samsung plans to begin volume production of the 512GB SSD next month.

I'm waiting for $0.4 per GB to upgrade... I'm waiting sitting down, luckily.

This is stated as if we don't already have drives capable of doing this...
Why do we want it? It's not that fast...
you realize $1 per GB will still make this SSD $512... I've seen a few SSD's on sale that have been $1.50 per gig, still way to much. tell me when this is in the ~$200 range
Can't wait for the time 128GB/256GB SSD to become cheap
Haha, turbo button..... oh, did i just show my age.
Ah the good old turbo button my 486DX2 used to rock in turbo mode LOL.
Yeap, my 286 16mhz had it too... dropped freq to 8mhz if I remember. Some games that were made to run on the 8088/86 woudl require me to press or they would run CRAZY fast.
I run the G2 intel SSDs at home and at work. Best investment ever. My system is as fast as it was day 1 when I installed... and no more disk thrashing noise (that pierces me like a craying infant).
Once we have higher production these things will be just as cheap as HDs, just a matter of time before they are obsolete. The future of SSDs looks bright with new NAND replacement tech as well. MRAM being one of them.
SSD's are absolutely choked by the SATA II standard. How come manufacturers havn't decided to utilize SATA III with these? I only know that Crucial has SATA III SSD's and their read/writes are 355MB/215MB for their 256GB model. OCZ has the edge with the PCI-Express SSD model, but the price on those are outrageous.
Not only am I waiting for these things to get cheaper, but I'm also waiting for the standard swap to SATA III.
Just to add, the OCZ models can acheive about 1.4GB read/write. Again, I say that until a more effecient bandwidth/connection standard is developed for these, they'll be little like loading bb's into a bazooka.
Sorry about that... as long the drives cost as much as three times the magnetics ones this drives won't be other than Gadgets for those who have lot to spend and less to worry about.
