PMC Flashtec controllers are powering the next generation of Memblaze PCIe SSDs. The Memblaze PBlaze 4 is designed for hyperscale and Open Compute Project architectures. The Flashtec controllers on the PBlaze 4 provide up to 850,000 IOPS for random read workloads, and 265,000 IOPS for random writes. Sequential performance is equally impressive, with up to 3.2 / 2.5 GB/s read/write available. NVMe provides the lowest CPU load and includes a number of architectural improvements for high-performance storage products. We recently took a deep-dive on the new NVMe specification in our Defining NVMe article.

PMC enjoys a market-leading position in NVMe controllers, and several hyperscale customers are already building their own NVMe SSDs with PMC controllers. Memblaze is currently the #1 PCIe SSD vendor in China and is expanding to the US and European markets, and expects to deliver over 6PB of flash storage this year. We recently took an in-depth look at Memblaze's latest product in the Memblaze PBlaze3L 1.2TB Enterprise PCIe SSD Review. Head to our IT/Datacenter section for the latest in competitive performance analysis of Enterprise PCIe SSDs.

The quest for benchmark world records led Paul further and further down the overclocking rabbit hole. SSDs and RAID controllers were a big part of that equation, allowing him to push performance to the bleeding edge. Finding the fastest and most extreme storage solutions led to experience with a myriad of high-end enterprise devices. Soon testing SSDs and Enterprise RAID controllers at the limits of their performance became Paul's real passion, one that is carried out through writing articles and reviews.
