RedmiBook Pro 15銳龍版磁盤、Screen and memory performance test：三者均無槽點
1、Screen Test：RedmiBook Pro 15銳龍版採用了一塊15.6英寸的IPS屏幕，分辨率高達3200*2000、Refresh rate 90Hz，We use Red Spider x to test the color gamut and brightness contrast of the screen。
The maximum brightness of this screen is 263nit，0%The contrast ratio is only 480 when bright:1，At other brightness，Contrast ratio can reach 1500:1That's all。0%The brightness has no reference meaning，So overall，The contrast ratio of this screen is very good。
The average Delta-E value of the RedmiBook Pro 15 is 1.23，It's a very good performance。The maximum Delta-E value is 3.56，Minimum 0.23。
2、Disk performance test：RedmiBook Pro 15 uses a KIOXIA 512GB M.2 NVMe SSD，Model is KBG40ZNV512G。
In AS SSD Benchmark，這512GB SSD的總分為3186，Sequential reading and writing exceeds 2000MB/s、900MB/s，4K隨機讀取44MB/s，隨機寫入138MB/s。In CrystalDiskMark Test，The sequential read and write speeds reached 2375MB/s and 1532MB/s respectively。
3、Memory performance test：
Memory cache test using AIDA64，Measured reads、Write、複製帶寬分別為43934MB/s、33969MB/s、38652MB/s，延遲為75.7ns。
