512GB Solid State Drive, M.2 2280, PCIe, Opal 2.0

頭3 個係sata 無問題.

後邊兩個都係 m2 2280.

一個寫NVme 一個寫 pcie.

係我水平低定lenovo 已經唔入流了?
thx

ps: google 完

m2 slot.

一係sata mode
一係pcie mode = NVme

PCI Express using NVMe
Used for PCI Express SSDs and interfaced through the NVMe driver and provided PCI Express lanes, as a high-performance and scalable host controller interface designed and optimized especially for interfacing with PCI Express SSDs. NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and complementing the parallelism of contemporary CPUs, platforms and applications. At a high level, primary advantages of NVMe over AHCI relate to NVMe's ability to exploit parallelism in host hardware and software, based on its design advantages that include data transfers with fewer stages, greater depth of command queues, and more efficient interrupt processing.

係lenovo 水平不入流了?

PCIE 可以係 AHCI

TOP

m2 2280 <--- 2280 係個SIZE 嚟
M2 即係NGFF,係一縮小版嘅PCIE
同PCIE 一樣可以話係一個PHYSICAL INTERFACE

NVME 係LOGICAL INTERFACE
PCIE 可以行NVME 或者AHCI
