The PX04SL SSD family is designed for read-intensive application workloads including web servers, data warehousing, media streaming and VOD and offers large capacities up to 4TB with 12.0 Gbit/s SAS interface.
The series’ 270K IOPS sustained random read performance helps read-intensive application workloads to realize superior results and assists organizations in minimizing total cost of ownership while maintaining high performance, reliability and endurance for maximum scalability.
Optimized for applications demanding 0.5 or less Drive Writes Per Day (DWPD), the family is equipped with unique customer-tunable feature allowing optimization for maximum performance or power efficiency. Additional features include power-loss protection and full data path protection. Each model supports pin-3 power disable for improved enclosure services control over storage media. Self-encrypting drive options with instant secure erase are also available.

  • Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
  • A kibibyte (KiB) means 210, or 1,024 bytes, a mebibyte (MiB) means 220, or 1,048,576 bytes, and a gibibyte (GiB) means 230, or 1,073,741,824 bytes.
  • 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 be different from the MTTF.
  • DWPD: Drive Write Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for five years, the stated product warranty period. Actual results may vary due to system configuration, usage and other factors.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • IOPS: Input Output Per Second (or the number of I/O operations per second)
