2x Samsung PM981a MZVLB1T0HBLR (RAID 0)

2x MZVLB1T0HBLR (RAID 0)

Two Samsung SSD PM981a 1TB nVME SSDs (MZVLB1T0HBLR-00000) in RAID 0 adds some performance to the already fast PM981a but also adds a higher risk of data loss. Each single SSD is a high end M.2 2280 SSD based on the Samsung Phoenix Controller (S4LR020) with 8 channels. The power consumption is specified with 2x 0.03 W in idle and 2x 5.6 W under load. The PM981a uses Samsung 3D-NAND TLC with 96 layers (V-NAND v5) and uses NVMe 1.3.

Asus Strix Scar 17 G733QS Laptop Review: Liquid Metal 7 nm AMD Zen 3 Is Stunning

Asus has quickly become one of the biggest supporters of mobile AMD Ryzen by entrusting the series to power some of its most well-known gaming laptops. The latest ROG Strix Scar 17 forgoes Intel entirely for a liquid metal-cooled Ryzen 9 5900HX to be as fast as an Intel Core i9 desktop PC.

AMD Ryzen 9 5900HX is a Mobile Beast: Asus ROG Zephyrus Duo 15 SE GX551QS Laptop Review

45 percent faster than the Core i9-10980HK, 45 percent faster than the GeForce RTX 2080 Max-Q, and over 7x faster gray-gray response times. The 2021 Zephyrus Duo 15 SE GX551 makes last year's Zephyrus Duo GX550 feel outdated already.
