Covering both ends of the solid state drive (SSD) spectrum, Corsair today announced the addition of two new drives to its Nova Series SSDs in 32GB and 256GB form.

The 32GB model is now the lowest capacity Nova drive Corsair carries. Read and write speeds check in at 195MB/s and 75MB/s, respectively, and like the other Nova drives, the 32GB model supports the TRIM command used by Windows 7.

At the opposite end of the spectrum, the 256GB model is Corsair's largest Nova SSD to date, but it's not just about capacity. The largest drive ups the performance ante with 250MB/s read and 195MB/s write speeds. Both drives sport the popular Indilinx Barefoot controller, 64MB of cache, and a SATA II interface.

Corsair didn't announce a price for either drive, but give the street prices of the 64GB and 128GB models, we expect the 32GB to check in at around $100 and the 256GB somewhere in the vicinity of $700.

Patriot on Wednesday launched a new line of SSDs built on top of the JMicron JMF612 controller. According to Patriot, you can expect "aggressive pricing and performance" from their Zephyr series.

"As solid-state drive technology advances, it is becoming more affordable, allowing SSD solutions to reach an increasing segment of end users. Patriot's objective is to offer the latest technology in our solutions which provide the best performance and price options", states Les Henry, Vice President of Engineering at Patriot. "Our Zephyr family of SSDs offer great performance, aggressive pricing and the inherent benefit of SSD technology over antiquated hard disk drives: quicker boot times and shorter application loading times. Including a Zephyr SSD in your desktop or notebook upgrade plans provides one of the best bang-for-the buck improvements you can make to your system."

That's all well and fine, but while Patriot was busy tooting its own horn, the company failed to mention exactly how much these new drives will cost. However they did release capacity and performance numbers,  which breaks down as follows:

• Zephyr 256GB: 240MB/s read, 180MB/s write
• Zephyr 128GB, 240MB/s read, 145MB/s write
• Zephyr 64GB, 240MB/s read, 85MB/s write

All three drives also ship with native support for the TRIM command in Windows 7. No word yet on when these will be available.

There's no mistaking OCZ's new Colossus LT SSD for what it is: a desktop drive. Measuring 3.5 inches, you're not going to stuff one of these inside your notebook, not if you have any hopes of it ever working again, anyway.

"Designed to offer PC enthusiasts a best-in-class storage upgrade from traditional hard disc drives, the innovative Colossus LT Series features incredible speed and ample storage for the complete gamut of gaming, multimedia and demanding productivity applications," OCZ claims. "The Colossus delivers all the proven benefits of SSDs such as superior system responsiveness, ultra-fast data access, and greater durability, while providing the storage capacity desktop users demand."

Available in 120GB, 250GB, 500GB, and 1TB configurations, the Colossus shatters the notion that SSDs have to be short on storage. Noteworthy features include an dual-controller design, internal RAID 0, 128MB of onboard cache, background garbage collection, read and write speeds up to 260MB/s each, sustained writes up to 220MB/s, and max IOPs of 15,000 (4K random).

Street pricing starts at about $450 and goes on up to about $3,500.
