Micron's RealSSD C300 SSD Is The Fastest Ever

Micron's RealSSD C300 SSD Is The Fastest Ever

Micron's no stranger to the world of flash memory, but it looks like the company is dead-set on going head-to-head with the Seagates and Western Digitals of the world. The new RealSSD C300 solid state drive is reportedly the first to deliver native SATA 6GB/s performance, which should mean that it does great in the benchmarks that are sure to come. The drive is based on 34nm MLC NAND flash and supports the high-speed ONFI 2.1 standard. It'll be available in 1.8" and 2.5" form factors, with both supporting 128GB and 256GB. Pricing has yet to be made known, but both should ship in Q1 of 2010. Rest assured we'll be doing everything we can to get one in the lab!


Micron RealSSD™ C300 Solid-State Drive: the Fastest Drive for Notebook and Desktop Personal Computers

First to Deliver Native SATA 6Gb/s Solid-State Drive

Announcement Highlights

  • Micron Technology, Inc. today introduced the RealSSD C300 solid-state drive (SSD), the fastest SSD for notebook and desktop personal computers (PCs)
  • The RealSSD C300 drive is the first to leverage the SATA 6Gb/s interface, providing read speeds of up to 355 megabytes per second (MB/s) and write speeds of up to 215MB/s
  • The RealSSD C300 drive is the first to use ONFI 2.1 high-speed synchronous NAND
  • Leveraging Micron’s industry-leading 34-nanometer (nm) multi-level cell (MLC) NAND flash memory, Micron’s RealSSD C300 drive – available in 128 gigabyte (GB) and 256GB capacities – is now sampling in limited quantities

BOISE, Idaho--(BUSINESS WIRE)--Micron Technology, Inc. (NYSE:MU) has raised the performance bar for SSDs. The company today announced its RealSSD C300 SSD, the industry’s fastest for notebook and desktop PCs. Micron’s new RealSSD C300 drive enables users to enjoy a more powerful and responsive computing experience—including faster operating system (OS) boot and hibernate times, and speedier application load, data transfer and file copying.

“The C300 SSD not only delivers on all the inherent advantages of SSDs – improved reliability and lower power use – but also leverages a finely tuned architecture and high-speed ONFI 2.1 NAND to provide a whole new level of performance,” said Dean Klein, vice president of memory system development at Micron.

While benchmark tests have shown that the C300 SSD is the fastest PC SSD leveraging the industry standard SATA 3Gb/s interface, the SSD performance is further boosted by natively supporting the next generation high-speed interface – SATA 6Gb/s.

What Does SATA 6Gb/s Mean? It’s All in the Numbers.

Native support of SATA 6Gb/s means that the data path between the host computer and the SSD is twice as fast as the previous SATA 3Gb/s interface. While some drive architectures require a trade-off between throughput-sensitive and IOPS (Input/Output Per Second)-sensitive data streams, Micron’s core design and higher speed interface provides advantages for both. The C300 SSD leverages the SATA 6Gb/s interface to achieve a read throughput speed of up to 355MB/s and a write throughput speed of up to 215MB/s. Using the common PC Mark Vantage scoring system, the C300 SSD turns in a score of 45,000 from the HDD Suite.

“Hard drives gain little performance advantage when using SATA 6Gb/s because of mechanical limitations,” said Klein. “As a developer of leading-edge NAND technology, along with our sophisticated controller and firmware innovations, Micron is well positioned to tune our drives to take full advantage of the faster speeds achieved using the SATA 6Gb/s interface. The combination of these technology advancements has enabled the RealSSD C300 drive to far outshine the competition.”

Designed Using Micron’s Industry-Leading 34nm NAND Flash Memory

The RealSSD C300 drive leverages Micron’s established 34nm MLC NAND flash memory, allowing the company to provide a cost-competitive, high-capacity SSD solution. Bringing another first to SSDs, Micron’s 34nm MLC NAND supports the high-speed ONFI 2.1 standard, ensuring the NAND performance keeps pace with the faster SATA 6Gb/s interface.

The drives will be available in 1.8-inch and 2.5-inch form factors, with both drives supporting 128GB and 256GB capacities. Micron is currently sampling the C300 SSD in limited quantities and expects to enter production in the first quarter of calendar 2010.

Now this is an exciting product! Wonder if all that speed is a result of the faster 6G SATA interface. I suspect it's not just that a combination of cache and improved flash controller algorithms.

>Pricing has yet to be made known

Pricing is expected to be way up there. But then again, motherboards with SATA 6G capability are also dear, so I suppose if you were building with one you have the bucks to afford a fast SSD.

Dave, I suspect that it's the memory and cache. The OCZ Agility and Summit series, which I looked at previously, have very similar numbers-- but the Agility uses faster RAM whereas the Summit uses a larger cache. (I went with the former.) Neither was in danger of saturating the 3 Gb/s interface, but put cache and speed together and it just might. And they did say they were using a new kind of memory, "ONFI 2.1 high-speed synchronous NAND" (no idea how that differs from other kinds or if it's just a buzzword party).

Those are some impressive speeds, and I do believe a lot of that has to do with the new 6G Sata interface.

I'll take 2 please :-)

Wouldn't be suprised if these started out around $500 for the smallest capacity.

Would make a great article to snag one of these up and run benchmarks of it on 3G and 6G Sata ;-)

Just for shits and gigs I copied a single 1.2GB file from my C: drive(raided SSDs) and pasted it directly under C:. Read and write on itself basically.... It was kinda slow... So then I pasted it onto one of my Disc drive from my C drive and it was faster! Rawr! Then I pasted from the Disc to the SSDs and it was the slowest lol

Sooooo Read and write to self... decent... read and write to something else.... much faster lol

Could just be vista sucks... it bursted at like 150MB/s then slowed to about 80. Stayed around 90-100 the whole time SSD to HDD. But HDD to SSD it was 60 the whole time.... gonna go try multiple smaller files.

Round 3 of my tests... Moved over 2000 photos ranging in sizes and file types pretty greatly.

It was slowest from SSD to SSD. It was faster HDD to SSD that SSD to SSD. Fastest from SSD to HDD. I learned my Smaller 200GB hard drive is about 25% faster than my 750GB hdd lol.

I'm very dissappointed in the IO ability of these drives :-(

i'm gonna go install some programs to the SSDs and HDDs and compare opening times... lol
