MZVLW512HAJQ-00000

Samsung PM981-NVMe-256G

MZVLB256HAHQ-00000

我司PM981系列為三星通用正式版,另外有部分961為聯想和索尼的工廠OEM貨源,此類產品為專供品牌電腦使用,在硬體上做過限制,肯定没有通用版的好了,给大家提供批次供参考 :標准的是-00000 或者00001這些,OEM的是0000so(索尼) 0000L(联想)
我們的產品参数 都是00000  ,其他英文字母的都是拆機的。
通過M.2介面PCIe3.0 X4通道工作.
相容大多數主機板包括INTEL NUC 5代CPU產品 x97和x99主 板 pre-cylindrical Mac Pro.

不相容 MacBook,MacBook Air或 MacBook Pro
Z97, H97, Z99, X99系列主機板BIOS必須更新升级, 才可以支持NVMe SSD, 詳情請到主機板廠商的網站查询主板型號是否支援NVMe通訊協議。

AHCI及NVMe差異請参考下面說明:
NVMe 針對商業應用強化架構,AHCI 簡易的適合個人用

NVMe 是 NVMe Express(Non-Volatile Memory Express)的簡寫,意即為非揮發性内存儲裝置,是由 Intel 所主導開發與制定規範。作用和它相同,大家也比較熟悉的是 AHCI(Advanced Host Controller Interface,進階主機控制器介面),兩者皆為儲存裝置與操作系统端,一種包含指令集、閃存存取控制、RTL(Register Transfer Level,緩存器傳輸級)、驅動程式層等介面標準。

AHCI 與 NVMe 重點特性比较:
NVMe 除了指令階列高出一截,還支援 MSI、MXI-I 中斷、如 4K 小文件随機存取性能強化、I/O 虚擬化架購、MIMO 存取能力等機能。簡而言之,就是 NVMe 架構傳輸效率優於 AHCI。

MTBF

MTBF is Mean Time Between Failure, and is the predicted elapsed time between inherent failures of a system during operation. As same word,
AFR (annual failure ratio) is 0.4%. MTBF can be calculated as the arithmetic average time between failures of a system.
