Toshiba XD5 NV-memory
Toshiba Memory Europe presents the XD5 series of new NVMe SSDs in a 2.5-inch form factor. Designed for data centers and cloud environments, the XD Series is ideal for use in NoSQL databases, data mining and streaming applications. The series is optimized for low latency and performance consistency in read-intensive workloads and also meets the requirements of Open Compute Project (OCP) applications and systems.

Based on a 64 Layer 3-Bit-per-Cell TLC (Triple-Level-Cell) BiCS FLASH and a PCIe Gen3x4 interface, the XD5 SSDs offer sequential read performance of up to 2,700MB/s and sequential write performance of up to 895MB/s at 7W power consumption. With a Drive Write Per Day (DWPD) value of 1, XD5 SSDs can be written daily with nearly 4TB random data for five years with a consistent performance rate. The random read and write performance is 250,000 and 21,000 I/O operations per second (IOPS), respectively, according to the vendor. This recommends the use of memory for read-intensive applications or workloads with high transaction volumes.

The flash memory and controllers contained in the new SSDs offer high reliability and data security as well as end-to-end error detection and power loss protection. The products come with a 5-year limited warranty.

The XD5 drives will be available during the second quarter of 2019.
