MLC NAND Flash Comes to Computing
For Mobile Applications: Fast Boot Time.
Improved Performance. High Reliability.

As one of the first companies to enter the solid state drive market with a family of products based on MLC NAND technology, Toshiba has achieved a 128GB1 drive in both 1.8-inch and 2.5-inch form factors and recently expanded its SSD family to include 256GB and small size 8GB,16GB, and 32GB Flash modules for Netbooks. In addition, 512GB and higher SSDs are planned as market conditions and pricing warrant.

Compared to hard disk drives (HDDs), SSDs realize faster boot time, higher reliability, improved performance and no mechanical sound. Toshiba's new SSDs integrate an intelligent MLC controller that supports fast read-write speed, parallel data transfer, and wear-leveling, and achieves performance levels comparable to those of single-level cell NAND-based SSDs.

Performance Advantages of SSDs
over Hard Disk Drives
  • Faster boot time
  • Improved performance
  • Higher IOPS
  • Fast random read and random write
  • Quieter operation (no mechanical sound)
  • Higher reliability
  • Low power consumption
  • Withstands greater shock and vibration
  • Reduced weight

1 When used herein in relation to memory density, gigabyte and/or GB means 1,024x1,024x1,024 = 1,073,741,824 bytes. Usable capacity may be less. For details, please refer to applicable product specifications.

2 Read and write speed may vary depending on the read and write conditions, such as devices you use and file sizes you read and/or write. (For purposes of measuring write speed in this context, 1 MB = 1,000,000 bytes). *Target spec at 43nm.

3 The (MTTF) Mean Time to Failure  is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may not resemble the MTTF.
