Flash Media / 3.5" Solid State Drives / SATA II / 128MB Cache / Internal RAID 0 / MLC / Dual Controller Design

The Colossus 3.5” Solid State Drive (SSD) Series is designed to meet the rigorous demands of consumer desktop and enterprise clients. The Colossus Series is the latest solution for professionals and enthusiasts looking to take advantage of the benefits of SSD technology and maximize their storage arrays.

The Colossus Series 3.5” SATA Solid State Drives deliver exceptional performance for high end desktops and are the result of OCZ’s latest breakthroughs in flash based storage.  Designed to offer PC enthusiasts a best-in-class storage upgrade from traditional hard disc drives, the innovative Colossus Series features incredible speed and ample storage for the complete gamut of gaming, multimedia and demanding productivity applications.  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.

The Colossus SSD is available in 120GB, 250GB, 500GB, and 1TB (1024GB) configurations to supply ample room for the complete spectrum of applications. The Colossus SSD series has an excellent 1.5 million hour mean time between failure (MTBF) and comes backed by a leading 3-year warranty and dedicated technical support, ensuring peace of mind over the long term.

*Consumers may see a discrepancy between reported capacity and actual capacity; the storage industry standard is to display capacity in decimal. However, the operating system usually calculates capacity in binary format, causing traditional HDD and SSD to show a lower capacity in Windows. In the case of SSDs, some of the capacity is reserved for formatting and redundancy for wear leveling. These reserved areas on an SSD may occupy up to 5% of the drive’s storage capacity.

**Solid State Drives DO NOT require defragmentation. It may decrease the lifespan of the drive. Please visit our SSD support forums for more information.




PC Perspective
"The Colossus kicks off our benchmark suite by promptly spanking everything else out there. None of that competition can match the crazy high write speeds of the Colossus. In addition, nobody else is making a single SATA SSD that scales to 1TB in size. OCZ has brought a worthy contender with their first 3.5" SSD solution. The added space of their enclosure was well utilized by a plethora of flash chips and no less than 4 SSD controllers. All things considered, the Colossus remains a solid solution for those wanting SSD performance in a 3.5" form factor."

Digital Trends: Best SSD Hard Drives
"Sporting a truly gargantuan capacity of one full terabyte (suitable for storing hundreds, if not thousands, of songs, videos and photos), the high-end model of OCZ’s aptly-named Colossus line of SSD drives impressively points the way to the future of the technology. For (upscale) PCs only."

Irish Daily Star
"OCZ has unleashed its Colossus 3.5” solid state drive series for high-end desktop users and enterprise clients. The Colossus series comes in sizes ranging from 120Gb to 1TB, and boasts maximum read and write of times of 260MB/s and a 1.5 million hours mean time between failures. With a sustained write time of 220MB/s and a design that should make it ideal for power users, we might well be adding it to our Christmas lists."

CPU Magazine
"Inside the drive, a pair of NAND-laden PCBs, each sporting Indilinx controllers, flows into a SATA backplane hosting three Silicon Image 5923 controllers. Where the Colossus blew us away was on write speeds, which were prety much at parity with read speeds...this is a huge advance. The data tells it all. If you want insane write performance, Colossus towers over the field."
