so 95mb/s write for the 64GB, 175mb/s write for the 128GB and 260mb/s write for the 256+512GB.

They are using 25nm chips btw like the newer OCZ Vertex 2E drives that started shipping from ocuk a few days ago.

the 1.8 or 2.5 refers to the size of the drive in inches and the 5, 7 or 9.5mm is the height of the drive.

here is the spec of the current C300 drives:

- Capacity: 64GB
- Cache: 128MB
- Controller: Marvell 88SS9174
- Read: Up to 355MB/sec
- Write: Up to 70MB/sec
- NAND Flash: Multi-Level Cell (MLC)
- Interface: SATA 6Gbps
- Low Power Consumption
- Shock Resistant
- TRIM Support (Requires Windows 7)
- Warranty: 3 Years

140mb/s write for the 128GB and 215mb/s write for the 256GB.

The 512GB C400 will be priced at $825 in 1,000 unit quantities - that works out to be $1.611 per GB. The 256GB drive will go for $425, the 128GB at $210 and the 64GB somewhere above $100. As 25nm production ramps up I wouldn’t be too surprised to see SSD prices drop down to the magical $1/GB price point. They have 50,000 4KB random write IOPS.

sounds fast hopefully not too expensive though

I can see these being a lot more successful than the C300, mainly because of the 95mb/s write speed, the c300 was only 70mb/s which is a lot slower than most new mechanical harddrives. the c400 isn't that much slower in write speeds than mechanical harddrives now so that will likely be less of an issue. I wonder if the IOPS performance has increased or not. The cache is a lower 128MB for the 64GB, the larger sizes have the same 128GB.

The vertex 2 50GB 25nm is under £90 so the price of this would have to be of a similar price to sell well as the 265mb/s write speed is multiple times faster than this 95mb/s and it is 14GB bigger.

I wonder if the IOPS performance has increased or not. I wonder how much cache and what controller they are using.

Yes, but who really cares about sequential write speeds on an SSD? You don't use them for storing media, so no big ISO's or Movies or backups. and if you're installing anything you're limited by the speed of your DVD or USB drive.
Whenever installing from a network mounted ISO I'm limited by other aspects of the installation process, like extraction.

if you are extracting 4.4gb of rar files for a movie you definately care about a near 3x faster extraction speed!

Except I doubt a Sandforce based drive would get anywhere close to it's advertised write speed when extracting a movie from a rar file since movie files aren't very compressible.

Excellent, even faster. I wonder if that means they will break even faster than the C300's?

Sequential read/writes mean bugger all for SSDs though.

Isn't it the random read/write speeds that matter a lot more?!

Any ETA on these drives yet?

I'll get the 512 version if it's £520 quid.

Ill get 256 if its £250

Looking forward to these too, might finally convince myself to get an SSD when they're released.

Nice, and shipping Feb according to anandtech. Was going to wait for intel's G3s, or Sandforce 2000 drives to arrive before getting an SSD for my new build, but these might just make me change my mind

More competition the better.. still waiting for 1£ / gb which will I expect be Intel g3.. common Intel

Has there been any firm release dates for these ??

Really? From the experience I have of mine its probably aout the same as my F3 if not slightly better. Installing windows, programes etc took about the same amount of time, so to say what you have is wrong.

At some point people will realise that write speed is not a deal breaker for normal people, for those who edit photos/ videos a lot etc maybe write is as important (not to say they arent normal!!!!! ) To be fair I can see crucial swapping out the c300s for these new ones and keeping the same price point, maybe a small premium.

And remember it's only the 64GB version of the C300 that is quoted at 70mb/s write;

* 128GG = 140MB/sec
* 256GB = 215MB/sec

I have the 64 GB version in my HTPC and it's a great performer. The fact that the write is only 70m/b is of no concern to me. I've installed all of my apps and the read speeds are all I care about.

I'm looking forward to the C400 and all the other SSD's which are due out this month. Another update from Anand: http://www.anandtech.com/show/4116/corsair-performance-series-3-ssd-benchmarks

Another person here waiting for £1 / GB

Untill SSDs are large enough (1TB+) and cheap enough so that you can use them to store large amounts of data (e.g. music, movies, etc), the sequential read write/speeds don't really mean much.

Most people at the moment are using SSDs solely for the operating system and frequently using programs, hence it's the random read/write speeds that they will care about.

hoping the 64GB will be about £60, that would be golden! Or if the c400 is more than that, hopefully this release will push down the price of the c300, what do you guys think?
