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。 |

PM981 Series (NVMe)
三星PM981 NVME SSD， 我司版本為全新通用正式版。
在PCI-E 3.0 x4模式下，三星公司宣稱其持續讀寫速度最高可達3000 MB/s和 1800MB/s
特别注意!!!!!此為NVMe本的SSD，
如果主機板規格書或BIOS升级說明没有寫出NVMe支援敘述, 則不相容, 請勿購買。 |

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. |
