Samsung 256GB PM981 M.2 PCIe NVMe Performance OEM SSD (Phoenix Controller)

Samsung PM981 ແມ່ນຜະລິດຕະພັນ OEM ທີ່ໄດ້ມາຈາກ Samsung 970 ມໍຣະນັນ.

ຂັບລົດນີ້ມີ Sams4 ລຸ້ນໃຫມ່ຂອງ Samsung ລຸ້ນ V-NAND ແລະຜູ້ຄວບຄຸມທີ່ມີປະສິດຕິພາບສູງທີ່ສົ່ງເຖິງ 3,000 MB / s ຂອງການອ່ານທີ່ອ່ານຕາມລໍາດັບແລະ 270,000 oops ອ່ານແບບສຸ່ມ.

ເຄື່ອງຄວບຄຸມຄວາມຈໍາ Samsung Polaris V2 ໄດ້ຖືກນໍາໃຊ້ໃນສະບັບຕົ້ນ, but ARM Phoenix memory controller was used in the later version.

It was popular for a while because of its good value for money.
