![]() ![]() Via the SATA3 interface, the average file copy performance reaches 74 MB/sec for a single file copy thread and scales to 158 MB/sec for 4 parallel file copy threads. On the other hand, when copying the same set of small files to/from the same SSD disk connected Scales to 126 MB/sec for 4 parallel file copy threads. When copying small files to/from an external USB3 SSD disk, the average file copy performance reaches 66 MB/sec for a single file copy thread and For all tested configurations, each test was performed 4 times using 1, 2, 3 and 4 parallel threads. Which is capable of performing different types of disk space analysis, file copy, file synchronization, file search andįile delete operations. Large Files - 1000 files with the average file size of 64 MBĪll benchmarks were performed using DiskBoss v7.4 (64-Bit version),.Medium-Sized Files - 10,000 files with the average file size of 4 MB.Small Files - 100,000 files with the average file size of 32 KB. Usb 2 vs usb 3 transfer speeds pro#Samsung 850 PRO 512 GB SSD connected to USB3.Samsung 850 PRO 512 GB SSD connected to SATA3.On exactly the same hardware platform, in the same order using the same sets of files using two identical SSD disks connected via the SATA3 and USB3 interfaces. USB3 hardware interfaces with two identical SSD disks connected to the same computer.įor this performance review we have performed a number of different file copy, file synchronization, directory scanning, file search, disk space analysis, file classification,ĭuplicate files search and file delete performance tests using the following three different sets of files: small files, medium-sized files and large files. The purpose of this review is to compare the performance of SATA3 vs. USB 3.0 increased the maximum transfer speed approximately ten times allowing to transfer data up to 5 Gbit/Sec and making the USB bus very useful for connectingĮxternal storage devices. Usb 2 vs usb 3 transfer speeds serial#On the other hand, external storage devices may be connected via a number of different hardware interfaces including the Universal Serial Bus (USB), Firewire, the Thunderbolt Normally, internal storage devices such as hard drives and SSD disks are connected to the computer via the SATA interface, which allows to transfer data up to 6 Gbit/Sec. ![]()
