It isn't that secret, but we don't have the full product specifications breakdown at this time. Here is what we do know. When it comes to capacity the new Marvell controller should be able to run in everything from 64GB to 512GB. ONFI 2.1 is supposed to be used with this controller and TRIM was confirmed working today on the show floor. We will get into those details in a few. Toggle Mode is also used; we will be getting into Toggle Mode in the next State of Solid State article in a week or so.

 

The controller itself is a bit of a mystery to us; we don't even know the model number at this time. One source is stating that this was once a product being considered for the enterprise market, while another states that it is just a new revision of the same Marvell controller used in the Crucial RealSSD C300. At this time we are pretty confident that it is has 8-channels and our own tests ran on a drive that has been beat to hell from R&D testing is able to read at close to 400MB/s and write around 200MB/s on a 128GB drive. Your first reaction is going to be the massive 400MB/s read speed and that is fine, but it is only half of the story. Still, that half of the story is pretty bad ass!

 

The drive we tested on today is the 128GB drive. It uses a Marvell controller. The Crucial RealSSD C300 uses a Marvell controller, but the 128GB version is only able to hit 140MB/s write speeds in ATTO. The 256GB model is able to hit just above 200MB/s, but not the 128 model. This fact is pretty much the main reason behind why we do not recommend the Crucial RealSSD C300 in the 100 / 120 / 128GB capacity range. There are other things as well, but it really all just leads back to the lower write speeds of the 128GB C300. The 256GB C300 is much more competitive to the SF-1200 drives in our real world tests and we see real benefits in writing data at 200MB/s when compared to 140MB/s in these tests.

 

At this time you can forget about pricing and availability specs. We will have that info around August, maybe sooner, but then again it might drag into September. It's really just unknown at this time and with the market always changing, what I say now will not mean a thing in August anyhow.
