【 摘 要 】

The paper presents the results of electrical and functional testing of 160 experimental samples of solid-state drives with capacities ranging from 256 to 1024 GB, assembled using 4 types of NAND-memory chips. As a result of testing, read and write speeds of SSD were measured in sequential and random modes. The maximum read and write speeds in the sequential mode were 540 and 410 MB/s, and in the random mode, 72000 and 68000 IOPS. When measuring disks of the same type, a relative speed variation was observed, which was significantly greater with write operations (3.7%) than with read operations (0.45%). It was also found that the write and read speeds were limited by the performance of the disk controller.
