UFS – Oge ọhụrụ na teknụzụ nchekwa ekwentị
Emepụta UFS laa azụ na 2010, mana ewepụtara ya na smartphones na 2015, yana ntọhapụ UFS 2.0. Dị ka eMMC, UFS na-eji NAND flash. Edokwala UFS ka ọ dochie eMMC na kaadị SD. UFS nwere bandwidths dị elu karịa 8-lane parallel na ọkara duplex interface nke eMMC. N'adịghịkwa ka eMMC, dabere na ụkpụrụ ụlọ SCSI. Na nkenke, ọ dị elu karịa ma nwee ọsọ ọgụgụ / ide ihe dị elu karịa eMMC.
Na February 2013, ụlọ ọrụ semiconductor Toshiba Memory (nke bụ Kioxia ugbu a) malitere ibupu ihe nlele nke 64GB NAND flash chip, nke bụ mgbawa mbụ iji kwado ọkọlọtọ UFS n'oge ahụ. N'April 2015, Samsung Galaxy S6 usoro ewepụtara dị ka ekwentị mbụ iji ọkọlọtọ UFS 2.0.
N'ezie, Xiaomi bụ ụlọ ọrụ na-agbaso mmepe ahụ. Ngwa Xiaomi na-esote, usoro Mi 5 bịara na teknụzụ nchekwa UFS 2.0. Ọ bụ nke a bụ Qualcomm Snapdragon 820 (MSM8996) chipset. UFS 2.0 nwere ọsọ ọgụgụ 350MB/s yana ọsọ ide 150MB/s.
Mgbe e mesịrị na Nọvemba 17, 2016, Qualcomm kwupụtara Snapdragon 835 (MSM8998) chipset na UFS 2.1. Chipset a, nke bịara na UFS 2.1 dị elu, nwere ọsọ ọgụgụ / ide ihe dị elu karịa nke bu ya ụzọ. Ngwa mbụ nwere Mi 6 a n'akụkụ Xiaomi. UFS 2.1 nwere ike iru 860 MB/s na-agụ ọsọ na 250 MB/s dee ọsọ.
