●Seagate One Touch SSD performance test

Then came the performance test of the Seagate One Touch SSD. Chen Ba conducted performance tests on the 2018 MacBook Pro 15 notebook computer and this year's latest Intel Z690 chipset motherboard. First, on the Apple Mac system, with 2018 The transmission performance was tested on the MacBook Pro 15 notebook computer of 2010, and the results are as follows:

Tested with Blackmagicdesign Disk Speed Test software on a 2018 MacBook Pro 15 laptop.

Tested with AJA System Test Lite software on a 2018 MacBook Pro 15 laptop. The test results of the two softwares are similar, and the maximum read and write speeds are about 850 MB/s to 950 MB/s.

In the Windows platform part, Chen Ba is connected to the ASUS TUF GAMING Z690 PLUS WIFI D4 motherboard for testing. The test results are as follows:

First, let's take a look at the information displayed in Crystal Disk info. Seagate One Touch SSD supports the most basic SMART debugging function, and the transmission interface adopts the USB 3.0 specification that supports USAP (USB Attached SCSI Protocol).

●Seagate One Touch SSD Crystal DiskMark test results

In the CrystalDiskMark test section, the Seagate One Touch SSD's sequential read score was 1042.04 MB/s, and the sequential write score was 1011 -ic/" title="1011 model">1011-ic/" title="1011 model"> 1011-ic/" title="Model 1011">1011-ic/" title="Model 1011">1011-ic/" title="Model 1011">1011-ic/" title="Model 1011">1011- ic/" title="1011 model">1011-ic/" title="1011 model">1011-ic/" title="1011 model">1011-ic/" title="1011 model">1011-ic/ " title="1011 model">1011-ic/" title="1011 model">1011-ic/" title="1011 model">1011-ic/" title="1011 model">1011-ic/" title ="1011 model">1011-ic/" title="1011 model">1011-ic/" title="1011 model">1011-ic/" title="1011 model">1011.21 MB/s, in 4K cell For the part of random write depth 1 of the block, the read speed is 32.62 MB/s and the write speed is 77.79 MB/s, which is roughly in line with Seagate's official data performance.

●Seagate One Touch SSD ATTO Disk BenchMark test results

In the test results, it can be seen that the Seagate One Touch SSD can achieve a maximum reading performance of 996.59 MB/s and a write performance of 977.78 MB/s in blocks above 512KB.

In the IO part of the number of reads and writes, the block below 8KB can maintain a high number of writes, and the read part has a maximum value in the block of 32 KB.

●Seagate One Touch SSD AS SSD BenchMark test results

In the AS SSD Benchmark part, the Seagate One Touch SSD got a total score of 1401. Under the 1GB test file setting, the sequential read and write results are: read 940.26 MB/s, write 932.26 MB/s.

The results of the random access IO part are 49927 iops read and 191973 iops written in the 4K 64-Third part.

In the AS SSD BenchMark copy test item, the results obtained by Seagate One Touch SSD are: ISO copy item 668.39 MB/s, program copy item 91.34 MB/s, game copy item 276 MB/s.
