										<content:encoded><![CDATA[<p>三星PM981係三星衍生嘅OEM產品 970 EVO.</p>
<p>該驅動器採用三星新嘅64層V-NAND同高性能控制器，可提供高達 3,000 MB/s嘅順序讀取吞吐量同 270,000 random read IOPS.</p>
<p>早期版本中使用了三星Polaris V2內存控制器, but ARM Phoenix memory controller was used in the later version.</p>
<p>It was popular for a while because of its good value for money.</p>
