We conclude our tour of the Patriot Memory booth at 2026 CES with a look at their latest internal SSDs. The Patriot Viper PV563H aims to be the world's fastest PCIe Gen 5 DRAM-less SSD. The drive features a 6 nm DRAM-less controller from SMI, comes in 1 TB, 2 TB, and 4 TB capacities, and offers sequential transfer rates of up to 14 GB/s reads, with up to 11 GB/s writes, both of which are the highest in the industry so far for DRAM-less Gen 5 SSDs. The drive features a passive aluminium heatsink, there's also a variant of this drive without the heatsink, called simply the Viper PV563. Next up, we have the Patriot Viper PV593, a flagship-segment drive based on the SMI SM2508 6 nm controller with DRAM cache. This drive comes in 1 TB, 2 TB, and 4 TB capacities, with sequential transfer speeds of up to 14 GB/s reads, and up to 13 GB/s writes.

Patriot Memory, a leading manufacturer of high-performance memory and storage solutions, today announced the launch of its latest PCIe Gen 5 x4 SSDs: the mid-range Viper PV563 and entry-level Patriot PA523. Joining the flagship Viper PV593, these new drives complete Patriot Memory's Gen 5 lineup, offering a full spectrum of solutions tailored to competitive gamers, professional creators, and everyday PC enthusiasts.

Viper PV563: Streamlined Power with Flagship Speeds
Engineered for users who demand strong performance without stepping up to flagship pricing, the Viper PV563 delivers sequential read speeds of up to 14,000 MB/s and write speeds of up to 11,000 MB/s under the latest NVMe 2.0 specification. Available in 1 TB, 2 TB, and 4 TB capacities, the 4 TB model features endurance ratings of up to 3000TBW (Terabytes Written).

In addition to the new high-end DDR5 memory kits, like the Viper Xtreme 5 CKD or the Xtreme 5 - 40th Anniversary Limited Edition, Patriot Memory also showcased a couple of new SSDs at the Computex 2025 show in Taipei, including the new Viper Gaming PV593, PV563 DRAM-less PCIe Gen 5 SSD, and the future PV573.

The stars of the showcase were the new Viper Gaming PV593 and the PV563 DRAM-less PCIe Gen 5 SSD, with the PV563 being one of the first DRAM-less PCIe Gen 5 x4 SSDs and probably the world's first DRAM-less SSD that reaches read performance of up to 14,000 MB/s. According to Patriot, the PV563 reaches sequential performance of up to 14,000/11,500 MB/s. The Patriot PV563 will be available in capacities of 1 TB, 2 TB, and 4 TB and uses Maxiotek's MAP1806 controller. With such performance, and fact that it lacks DRAM cache, could make it one of the fastest yet affordable SSDs on the market when it launches. The Patriot PV593 is a higher-end version with DRAM cache. It uses a 6 nm SMI SM2508 controller, and will also be available in 1 TB, 2 TB, and 4 TB versions. It has the same sequential read performance of up to 14,000 MB/s, but much higher write performance of up to 13,000 MB/s. The random 4K read performance is at up to 2,000K IOPS. Patriot also plans to release the PV573 SSD that should fit between these two versions in terms of performance, but the company was still not ready to share further details.
