Toshiba is busy at Flash Memory Summit in Santa Clara, but the big news is coming across as Toshiba has now launched their XL-Flash.

Toshiba Memory introduces new speedy SLC XL-Flash |

XL-Flash is an SLC part designed for very low latency. It is meant to combat Samsung's Z-NAND or even Intel 3D Xpoint which powers their OPTANE storage solutions.

XL-Flash is stated as you can see above to have a 5-microsecond delay which is 10x faster than existing TLC (50-microseconds). XL-Flash will be available to partners, which is a nice shift since Samsung's Z-NAND is locked to their models. We should see some very capable and speedy drives coming very soon.

Key Features

  • 128 gigabit (Gb) die (in a 2-die, 4-die, 8-die package)
  • 4KB page size for more efficient operating system reads and writes
  • 16-plane architecture for more efficient parallelism
  • Fast page read and program times. XL-FLASH provides a low read latency of less than 5 microseconds, approximately 10 times faster than existing TLC2

I started my PC journey around the age of six in 1989. Now to present day, I have established myself in the overclocking world and even the XOC scene spending many years pushing hardware on LN2 to find the far edge limits of all new and even old platforms I can get my hands on. I have also worked with design and R&D on various components including PC chassis to optimize the layout and performance for enthusiasts like myself.
