What is significantly faster, like 3 times as fast as standard SSD is Sonnet Technologies PCI-E card with 4 embedded 2 TB SSD’s. The read/write time is supposed to be 1.4 GBps and the standard SSD drive is said to be 0.4 GBps.
B= Byte.
Although they now have PC Drives with up to 5 GBps these are not what they recommend for Mac.
Mine will be here next week. I’ll let you know if I see a difference in speed from my current SSD drives.
