Micron's RealSSD C400 uses 25nm NAND at $1.61/GB, Offers 415MB/s Reads

Here’s a little deja vu for you. At last year’s Storage Visions (a small storage show that precedes CES) Micron announced its first 6Gbps SSD, the RealSSD C300. Although met with its fair share of growing pains in the form of firmware issues, the C300 ended up being a competent performer throughout most of 2010.

This year, once again at Storage Visions, Micron announced its next generation SSD: the RealSSD C400. Based on the same architecture as the C300, the C400 is a combination of IMFT 25nm NAND, a slightly tweaked controller and a significant improvement in firmware.

The controller is still a Marvell 6Gbps solution, while the firmware is all Micron’s own development. As Micron (and SandForce) have proved in the past, it’s not so much the raw processing power of the controller but the architecture of the firmware that really matters.

The controller is still paired with a 256MB DRAM to cache LBA to NAND page mapping and act as a scratch area for the Marvell controller. Unlike the C300 however, the 64GB version of the C400 will only have a 128MB cache (the 64GB C300 had a 256MB cache).

The move to 25nm NAND gives us one major improvement: cost. 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.

Sounds good, however even though prices are dropping they're still a little too high for my taste. Would like to see the 256 models get under $400 - 399 doesn't count. That's when you know prices are moving in the right direction for everyday users.

My two cents.

Great! Now all I need is a couple of grand to replace my mirrored OS drive.

Even at the current lower price level, SSDs aren't cost effectively viable as a HDD replacement.

When used as a boot drive they add amazing performance.
Keep all of your data, music, movies, files and folders, on a HDD.
Use the SSD for OS and all your apps, unless you have over 50GB of apps you can get a reasonable sized SSD.

Dave76 hit the nail right on the head.. I'm very happy with my drive, as it's only a boot drive with all my programs installed that I would use on any given day of the week. I killed the hibernate file, (don't use it) and moved my swap-file to the HDD. Walla!! Happy as a clam!!
