PMC and Memblaze unveil PCIe SSD with 8TB capacity, 3.2GB/s bandwidth

PMC-Sierra, a leading designer of storage controllers, and Memblaze, a producer of high-end storage accelerators, have unveiled a new extreme-performance PBlaze4 solid-state drive that boasts both extreme capacity and extreme performance.

The Memblaze PBlaze4 solid-state storage solution is powered by PMC’s Flashtec NVM Express (NVMe) controllers, use PCI Express 2.0 x8 interface and come in either HHHL (half-height, half-length) or FLHL (full-height, half-length) card-type form factor. The drives can use either single-level cell (SLC) or multi-level cell (MLC) NAND flash memory, depending on requirements for performance and reliability.

The PBlaze 4 solid-state drives can feature up to 8TB capacity, up to 3.2GB/s sequential read and up to 2.5GB/s sequential write performance. The SSDs also provide up to 850,000 I/Os per second (IOPS) for random read and 265,000 IOPS for random write performance.


The solid-state storage accelerators like PBlaze 4 are targeted at hyperscale and big data deployments. PMC’s Flashtec NVMe flash memory controller family includes 16-channel and 32-channel devices to enable SSDs with up to 8TB of storage and extreme performance.

“PMC is pleased to be partnering with Memblaze to provide the highest performance and most advanced PCIe SSD solutions for China’s technology and hyperscale leaders,” said Derek Dicker, vice president of the non-volatile solutions group at PMC. “We look forward to enabling the significant growth opportunities for flash in China’s data centers and hyperscale deployments. Memblaze is a strategic partner for PMC to support these critical market segments in China and abroad.”


Ultra high-end solid-state drives like Memblaze PBlaze 4 are configured in accordance with particular requirements, as a result, not only their prices vary greatly, but also their capabilities depend on particular configuration.

KitGuru Says: While each PBlaze 4 SSD can cost tens of thousands of pounds/dollars, they are worth it, since they enable performance not possible on storage systems based on hard disk drives or low-end solid-state drives.
