Although the latest AMD and Intel platforms a few months ago introduced support for PCI-Express 5.0, the next generation interface for ultra-fast semiconductor media and unannounced graphics cards, until now there was no device that could test the actual capabilities of this standard. Only today there was such an opportunity, because the Corsair MP700 finally went on sale. The top SSD from the American manufacturer opens the next chapter in the evolution of semiconductor memories, and automatically wins the title of the fastest in the world, although the price of technological progress is high. I invite you to the premiere of the Corsair MP700 review …

SSD (Solid State Drive) technology is older than it might seem, because the first carriers that are the ancestors of those currently available appeared even before Intel 286 processors. Why is it worth getting an SSD? The advantage of semiconductor models over disk models is devastating – devices using flash memory are more durable and noiseless due to the lack of moving parts. However, most importantly, it is more efficient – especially in the case of operations on small or very small files. SSDs use four types of modules NAND Flash SLC, MLC, TLC, and QLC The first two are less common, and most consumer models are based on other systems. The main factors for carrier performance are also the appropriate controller and firmware, which together determine the final performance of the tested devices.
The Corsair MP700 is one of the first SSDs to use the PCIe 5.0 x4 interface, opening a new chapter in the evolution of storage.
The Corsair MP700 uses the latest 8 channels Phison PS5026-E26 Controller, the only chip currently available to manufacturers offering PCI-Express 5.0 media. The situation was similar to the premiere SSD PCI-Express 4.0 x4, where Phison also caught fire. The successor to the highly successful PS5018-E18 is built on similar foundations. The module is manufactured using 12nm FinFET lithography, with two ARM Cortex R5 processors and three CoXProcessor. The Phison PS5026-E26 is also NVMe 2.0 compliant, supports AES 256-bit / TCG Opal 2.0 hardware encryption and has an LPDDR4 cache. The theoretical capacities of the controller are 14,000 and 12,000MB/s, respectively, for sequential read and write, while the maximum media capacity can be up to 32TB. 3D 232-layer TLC NAND is also standard onboard the Corsair MP700.

Corsair Dominator Platinum RGB 7200MHz CL34 DDR5 RAM Test – How’s the Performance with Intel Core i5-13600K?
The 2TB Corsair MP700 achieves 10,000MB/s sequential read and write, adding 1,500,000 and 1,700,000 IOPS respectively. The declared performance is impressive, far ahead of the fastest PCI-Express 4.0 x4 media, but only real tests will verify this device’s capabilities. The manufacturer states in the specs for the 2TB variant 4096MB of Hynix DDR4-4266 memory, double the previous generation models, which should also be reflected in the results. The Corsair MP700 comes with a 60-month manufacturer’s warranty, but the TBW value of 1.4 PB seems pretty average. It is also worth noting that initially the upper disk carrier was supposed to come with active cooling, that is, a heatsink with a small fan. However, the company abandoned this idea, because the cooler’s work culture turned out to be extremely unsatisfactory. So we finally get a ‘naked’ vector of our own arrangement.
