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.

fayzaan 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 :D.Reply

twbg4cq 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 :)Reply -
renniz Question. What is the advantage of using one channel? Less cost and/or higher performance? The footprint is larger.Reply -
the_krasno tmaxI want a SSD. Just waiting for the prices to drop a little more.Reply
Have a chair, sit with me, this is going to take a looooooooong time. Want some gum? -
sirmorluk 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.Reply
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. -
digitalrazoe 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!!!Reply -
buzznut rennizQuestion. What is the advantage of using one channel? Less cost and/or higher performance? The footprint is larger.Yes what is the advantage? Wouldn't it make more sense to take this technology and use mutlichannel to beat current SSD speeds?Reply -
digitalrazoe 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.Reply
