Nguva pfupi yadarika, paChina Electronic Information Expo (CITE2019) yechinomwe muShenzhen, yekutanga solid-state drive SSD P8260, yakaunganidzwa chete kubva kuChinese zvikamu, yakaratidzwa pakamira Tsinghua Unigroup. Iyi iseva-giredhi SSD umo mutongi, DRAM buffer uye 3D NAND array akagadzirwa uye anogadzirwa muChina. Zvakanaka, China yatora rimwe danho uye inotarisira kutevedzera nzira iyi yekupedzisa rusununguko kubva mundangariro yekugadzirwa kwekunze.
Chero ani anotevera nhau dzekuvandudzwa uye kugadzirwa kwe3D NAND memory muChina anoziva kuti kugadzirwa kweflash memory chips kunoitwa nemubatanidzwa neTsinghua, Yangtze River Storage Technology (YMTC). Iwo maP8260 anotyaira anoratidza YMTC yekutanga 32-layer 3Gb 64D NAND zvigadzirwa. Nechokunopera kwegore, mugadziri achatanga kugadzira 128 Gbit 64-layer 3D NAND chips, izvo zvinobvumira YMTC kuti iwanikwe mune zvekutengesa - ukuwo kugadzirwa kuri kurasika.
DRAM ndangariro yeSSD buffer inogadzirwa neTsinghua inotsigira Guoxin Micro. Saizi yebhafa haina kutaurwa. Iyo controller yakagadziriswa nekambani yeChinese Beijing Ziguang Storage Technology, iyo zvakare yakabatana neTsinghua Unigroup.
Iyo P8260 controller uye dhiraivha inotsigira NVMe 1.2.1 protocol uye PCI Express 3.0 x4 interface. Tsigiro ye16 ndangariro chiteshi inoziviswa, iyo inovimbisa yakakwirira bandwidth, asi chaiyo data pakuita kweP8260 haina kutaurwa. Kuti ushande neiyo DRAM buffer, processor ine yakavakirwa-mukati mbiri-chiteshi memory controller ine 40-bit bhazi uye ECC rutsigiro. Mavhezheni maviri eSSD P8260 anoratidzwa: ine huwandu hwe1 uye 2 TB muchimiro zvinhu zvePCIe kadhi uye U.2 drive.
Pamusoro peP8260 madhiraivha, mugadziri akaratidzawo vatengi SSDs eP100 uye S100 mhuri. Nekudaro, kambani inotenga 3D NAND memory yemhando idzi kubva kune vanobatana. Mumwe mubatsiri akadaro, semuenzaniso, ndiIntel.
