The PX04PRB Series is a high-performance NVMe SSD optimized for a broad set of enterprise workloads. Applications such as web-server, SQL server, write-once read-many (WORM), and high-transaction / trading (OLTP) can benefit from the PX04P Series balance of endurance, capacity, performance, and reliability. The PX04P Series was also designed for environments where power requirements are a premium, requiring only 18.5W for maximum active performance and maximizing the power to performance (Watt per IOPs and Watt per MiB/s) ratio compared to similar 25W NVMe SSD solutions.
The PX04P delivers excellent performance on sequential reads, up to 3,100 MiB/s and sequential writes up to 2,350 MiB/s. For random workloads, speeds of up to 660k IOPs for random reads and 80k IOPs are achievable depending on the drive’s capacity.
The Read Intensive PX04P supports 1DWPD (Drive Writes Per Day) and is designed for read-intensive applications such as media streaming, data warehousing, JBOF, and web servers.

  • 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.
  • GT/s:Giga Transfers per second (The transfer speed only for effectiveness data)
  • 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.
  • The performance are mesured in Sustained condition.
  • 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)
