It is NOT going to improve your throughput. Bottom line, enabling RAID is a complete waste of time. Needless to say, with all of these devices and interfaces vying for the throughput of the DMI 3.0 link, there is little chance of getting the theoretical throughput of 3.94GB/s to one of the M.2 NVMe SSDs, let alone that required for overlapped operations to two M.2 NVMe SSDs. This includes: the two x4 PCIe M.2 connectors, the x1 PCIe M.2 connector for WiFi, the x1 PCIe for the SD Card Controller, the x1 PCIe for the GbE Controller, USB-C (USB 3.0), 6 USB 3.0, 2 USB 2.0, two SATA 6.0Gb/s lanes, the LPC Bus (connection to Super I/O component), the SPI bus and the I2S connection to the Audio CODEC. The throughput of the DMI 3.0 link is used by the PCH to support *many* interfaces.That is, overall theoretical throughput is 3.94GB/s. CrystalDiskMark is a small tool that allows you to carry out different tests on the drives of your computer to check the performance when it has to read or. The CPU communicates with the PCH via a DMI 3.0 link.

(If the default is 5, you can change it to 3, which should be enough to get more accurate results. The 4 PCIe lanes routed to each of the two M.2 connectors come from the Platform Controller Hub (PCH) component. To measure your drive's read and write performance using CrystalDiskMark, close all running programs and use the following steps: Step 1: Launch CrystalDiskMark to access its interface.The theoretical throughput of a x4 PCIe connection is 3.94GB/s. The transfer rate of a PCIe lane is 8GT/S.Give it a try yourself as it is free to download.Yes, I have a suggestion: Don't waste your time using RAID it is NOT going to improve your SSD throughput. CrystalDiskMark can measure sequential reads/writes speed, measure random 512 KB, 4 KB, 4 KB (Queue Depth = 32) reads/writes speed, has support for different types of test data (Random, 0 Fill, 1 Fill), includes basic theme support and has multilingual support. It is useful for comparing the speed of both portable and local storage devices. CrystalDiskMark is a disk benchmark utility that measures performance for sequential and random reads/writes of various sizes for any storage device. Currently, the program allows to measure sequential and random read/write speeds. Here you can always download the latest version.ĬrystalDiskMark is designed to quickly test the performance of your hard drives. CrystalMark is a Storage benchmark and system information application from Crystal Dew World.
