Performance - Storage Subsystem - USB 3.1 & SSD SATA3
Below, you are looking at a Plextor EX1 USB 3.1 gen 2 (review here) flash drive with today's tested motherboard. It is one of the faster sticks available on the market and makes USB 2.0 at 25~30 MB/sec look rather pale in comparison. That is maximum performance for the USB stick right there.
- USB 3.0 is now called USB 3.1 Gen 1 (Speed up to 5 Gbps)
- USB 3.1 is now called USB 3.1 Gen 2 (Speed up to 10 Gbps)
SATA 6 Gbps performance
Below, we show SATA3 6 Gbps (BIOS at AHCI mode) performance with a SATA3 SSD. Here we are using a SATA3 connection directly to the processor.
** Windows has been CPU Meltdown/Spectre security patched - GBT, however, did not have their BIOS patch ready at the time of writing.
The SATA3 based SSD is connected to the SATA3 (6Gbps) chipset controller. AHCI mode is enabled in the BIOS, especially with SSDs that helps a little on peak performance. These native SATA3 (6 Gbps controllers) from both AMD and Intel are the fastest your money can get you really. Some motherboard partners will add 3rd party SATA3 controllers which often are a little limited in performance overall. Still, you'd see 300 to 400 MB/sec on such ports, plenty for an average SSD, HDD or optical unit of course.
