Memblaze’s PBlaze5 X26: Toshiba’s XL-Flash-Based Ultra-Low Latency SSD
CRANK

With the annual Flash Memory Summit kicking into high gear this week, Memblaze will be showcasing one of the industry’s first ultra-low latency NVMe SSDs based on Toshiba’s XL-Flash memory. The drives promise consistent, high performance as well as ultra-low latencies and will compete against Intel’s Optane and Samsung’s Z-NAND drives for mission critical and performance-demanding applications.The Memblaze PBlaze X26-series drives are based on the company’s proprietary controllers and are paired with Toshiba’s XL-Flash memory. XL-Flash was announced last year, promising to reduce operational latencies by an order of magnitude compared to 3D TLC NAND (i.e., 1/10th of 3D TLC NAND latency). Memblaze claims that prototypes of the PBlaze X26-series SSDs feature a 4K random write latency under 10 μs and a 4K mixed read-write latency as low as 26 μs on average. In fact, the company expects the final drives to offer a latency of below 20 μs. This is still higher when compared to Inte…
