Solid-State Drive Performance + Hard Disk Drive Capacity = Simple


Speed Meets Capacity

Want Solid State Drive (SSD)-like storage performance, with Hard Disk Drive (HDD) capacity, at a lower cost than a large SSD? Combine an Intel® Solid-State Drive 311 Series, a HDD, and Intel® Smart Response Technology for a a simple way to accelerate storage performance. Intel Smart Response Technology—enabled by systems utilizing the Intel® Z68 Express Chipset with Intel® Rapid Storage Technology (Intel® RST) version 10.5 and second generation Intel® Core™ processors—seamlessly combines the responsiveness similar to a high-performance SSD with the capacity and low cost of a hard drive. The two technologies appear as a single C:\ driver letter that provides you with the familiar storage identifier. The system automatically learns which files are accessed frequently and copies them from the HDD to the SSD. The next time you access these files, the system loads them from the fast SSD rather than the slower hard drive. When you request infrequently-used files, the system loads them from the hard drive when you need them. Systems boot fast, applications load fast, and the system feels snappy, like an SSD.

Performance and Endurance

The Intel SSD 311 Series utilizes Intel 34nm Single Level Cell (SLC) NAND to offer high performance and longer endurance over Multi Level Cell (MLC) NAND, which is typically used in other SSDs. Changing the NAND components from MLC to SLC increases the performance and longevity of Intel Smart Response Technology. With powerful Native Command Queuing that enables up to 32 concurrent operations and proven Intel architecture; the Intel SSD 311 Series drastically outperforms traditional hard disk drives.

World-Class Reliability

As a member of the Intel® SSD generation that changed the industry with its overall performance, value, and reliability; the Intel SSD 311 Series draws from decades of Intel memory engineering experience, and compute-quality Intel 34nm NAND Flash memory manufacturing processes. The Intel SSD 311 Series also features low write amplification and a unique wear-leveling design for higher reliability, which means Intel SSDs not only perform better, they last longer.

Flexible Form-Factor

Flexible Form-Factor   

Accelerate storage performance using Intel SSD 311 Series 2.5" or mSATA form-factors. The 2.5" form factor Intel SSD 311 Series can be added to an Intel Z68 Express Chipset desktop system by using one of the multiple standard hard drive bays.





   Flexible Form-Factor

For Small Form-Factor (SFF) and All-In-One (AOI) systems, the mSATA Intel SSD 311 Series saves space by mounting the device on the motherboard and not utilizing a hard drive bay. The mSATA form factor is up to eight (8) times smaller than a 2.5" hard drive, and weighs less than 10 grams. Small systems can come alive too!




Scalable Storage

Replacing an HDD with a single large SSD requires purchasing enough SSD capacity to allow for file accumulation (more and more applications, pictures, audio, and video). When full capacity is reached, you can migrate the data to external storage or you can replace the SSD with a larger capacity SSD. However, Intel Smart Response Technology helps preserve your Intel SSD 311 Series investment by focusing file accumulation on the less expensive HDD. As storage capacity requirements increase, the HDD can be upgraded to larger capacity at HDD replacement cost. The Intel SSD 311 Series, holding frequently used files, remains.

Increase your PC's performance without giving up storage capacity by combining Intel Smart Response Technology, your favorite hard disk drive, and an Intel SSD 311 Series. Performance made Simple!
