										<content:encoded><![CDATA[<p>Samsung PM981-ը Samsung-ից ստացված OEM արտադրանքն է 970 EVO.</p>
<p>Այս սկավառակն ունի Samsung-ի նոր 64-շերտ V-NAND-ը և բարձր արդյունավետության կարգավորիչը, որն ապահովում է մինչև 3,000 ՄԲ/վ հաջորդական ընթերցման թողունակությունը և 270,000 random read IOPS.</p>
<p>Վաղ տարբերակում օգտագործվել է Samsung Polaris V2 հիշողության կարգավորիչը, 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>
