2x Samsung SM951 MZVPV512HDGL (RAID 0)

2x MZVPV512HDGL (RAID 0)

Two Samsung SM951 MZVPV512HDGL drives used together as a RAID 0 array are a high-performance storage solution with a total capacity of 1 TB that Notebookcheck first tested in 2015.

A single 512-GB SM951 is rated for sequential read rates up to 2.15 GB/s, with writes up to 1.55 GB/s. Our tests of the RAID carried out with AS SSD 1.6 showed rates of 2.4 GB/s and 2.83 GB/s, respectively, which is about what a generic budget NVMe PCIe 4 x4 SSD delivers in 2026.

RAID 0 is an array of two or more drives. It is designed to increase performance by processing data in a multi-threaded fashion. This is achieved by distributing the contents of files roughly equally among all disks in the set, the more, the merrier.

Asus ROG G701VO-CS74K Xotic PC Edition Notebook Review

A more down-to-Earth GX700. Take away the water cooling capabilities of the GX700 and you're left with a lighter and wholly capable system in the form of a G701. While performance is where we expect it to be for a high-end gaming machine, the system still suffers from many of the same drawbacks as its ROG series siblings.

Asus GX700 Notebook Review

Bring in the water! While water-cooled desktop systems are not uncommon, most notebook models are exclusively cooled by air. Asus still takes this step and presents the GX700, a combination of high-end laptop and external water-cooling. As one of the first editorial offices, we had the chance to take a closer look at the overall package.
