SSD Does 130MB/s Write on Single Channel
MOSAID's HLNAND-based SSD achieves high performance using a single channel.
Last week MOSAID Technologies revealed a prototype SSD that was capable of write speeds of up to 130MB/s and read speeds up to 213MB/s using a single channel of MOSAID's HyperLink NAND (HLNAND) architecture and interface. Currently SSDs require eight or more channels to reach the same level of performance.
"HLNAND Flash combines MOSAID's HyperLink memory technology with industry standard NAND Flash cell technology," the company explained in a press release. "HLNAND delivers sustained input/output (I/O) bandwidths an order of magnitude higher than conventional Flash by utilizing a point-to-point ring topology that achieves an extremely high level of signal integrity and significantly reduced loading."
MOSAID added that the 3.5-inch prototype is fully functional, Serial ATA2-compatible, and incorporates a Field Programmable Gate Array (FPGA)-based controller with the HLNAND modules. It uses two 64GB HLDIMM modules (eight multi-chip packages (MCPs) per module, 16 MCPs in total) arranged on a single channel. MOSAID said that it provided the HLDIMM modules while INDILINX built the controller and system board.
Licenses for manufacturing MOSAID's HLNAND 64Gb NAND Flash memory device and 64GB HLDIMM module in production quantities are now available. MOSAID will be showcasing its HLNAND SSD prototype at the 2010 Flash Memory Summit held in Santa Clara, California on August 17 - 19. To learn more about the HLNAND technology, head here.
No word on when a SATA3 prototype will show up.

About to move to my first SSD drive this month as a boot drive probably 128gb. I've had raptors and velociraptors for the last few years it's time for a upgrade.
Wow, great news! hopefully they can get this rolling quick. I have SSD so far and am very happy with the performance so far, but this will take things to the next level
.
I want a SSD. Just waiting for the prices to drop a little more.
I'll be more likely to buy an SSD when the price ratio is around a dollar per gig, but this is good news too
Question. What is the advantage of using one channel? Less cost and/or higher performance? The footprint is larger.

Have a chair, sit with me, this is going to take a looooooooong time. Want some gum?
HLDIMM!!! Now this is a great improvement over existing SSDs. Imagine instead of having to purchase an entire new SSD paying for the enclosure, controller and new PCB/NAND just buying expandable HLNAND modules. Pop the old out and the new in.
I know it does not say this is possible in the article but if you look at the specimen provided it clearly has DIMM slots.
hmmm .. it will be interesting to see how this twist on the memory chips used stacks up over time. As for the single channel vs multiple channel -- if there is any data failure it will be detected sooner or less of a pain in the butt -- plus this makes scalability extremely flexible and low CPU utilization through put/over utilization.. bring it on!!!

Yes what is the advantage? Wouldn't it make more sense to take this technology and use mutlichannel to beat current SSD speeds?
The way I see the advantage is instead of 8 channels at 128gigs all together you can ( if they will develop such drive ) 128gigs per channel working as one unit with astronomically high throughput ... plus if this technology takes off then the multichannel ssd will HAVE TO come down in price... its a win win situation.
Could I do RAID 0 with this SSD?
WOW! It only makes me glad I've waited so long. When they release SATA3 SSDs in mass quantities it will be because of this! I'm going to be way excited for this! I'm already excited!

I think the point is that this is getting this kind of performance using only 1 channel, if you put it into a typical ssd setup using multiple channels your gonna (very) quickly max out what sata itself can do..
8 channels on a typical ssd vs 1, maybe 2 channels on this setup should be a lot less complex to develop and manufacture
Have a chair, sit with me, this is going to take a looooooooong time. Want some gum?
LOL, here have a cookie, you'll be right as rain...

Stay a while, and listen.

Observe the sound from the corner of the room, your hard drive indexing away for Vista search.. it almost drowns out the pitter patter of rain
this'll blow SATA 6Gb out of the water pretty quick. So, when is SATA 24Gb coming out?
I have a feeling rather than bring prices down, a drive using this may end up being priced above existing premium SSDs, for enthusiasts and enterprise useage. Very few components have margin anymore and I'm sure companies making SSDs don't want to turn the SSD market into the high volume low margin market that Seagate and WD created. SSDs should be cheap now, but they are obviously not.
Too bad prices are so high on these things. My single Patriot Inferno 100GB is faster than my 3 WD 500GB Blacks striped together and I'd buy more but they are over $300 CAN each.
looks big. enormous in front of ssd. am i right :?
Stay a while, and listen.
I see what you did there.
I have an Intel X25M 160GB and I LOVE it! I am looking forward to faster drives in the future.
I don't see this taking off. It is "single-channel" only in name. Notice there's still 16 flash chips on there? They're just daisy-chained together in a ring, as the article states, but half the people commenting don't RTFA.
It still takes just as many flash modules to reach this performance level as with the existing "multi-channel" controllers, so there's absolutely no gain here. It also requires their proprietary flash modules instead of the standard ONFI NAND flash that everybody else is using right now. It's like Rambus DRAM all over again.
Something like this will need to be SATA 3 or on a PCI-e connector. Once it gets more channels, it will easily oversaturate SATA 2.

Sounds like the difference between Token-ring networking and Ethernet networking.
Are each of the 8 MCPs in a Token-ring in each module, or do the 2 modules (pack of 8 MCPs) make up the token ring? Cool stuff.
Soon my boot up drive will be an SSD.
Soon my boot up drive will be an SSD.
soon your wallet will be robbed.
If this is scalable..Imagine what 8 channels or even 4 could do, maybe we need a new SATA standard.
I hope they improved anti-performance degradation, as it's a serious problem for me preventing me to buy a SSD even if prices dropped.
