G-Tech G-RAID with Thunderbolt 3
8 TB
Question about G-Tech G-RAID with Thunderbolt 3
I bought the G-Raid (2x4TB or 8TB) and found that it runs almost twice as fast with the RAID-0 8TB setting! When copying under RAID-0 8TB a speed of 480MB/s is achieved, as RAID-1 (2x 4TB) only 253MB/s! Does anyone know why this is and whether there is a way to achieve the same speed under RAID-1 (2x4TB)??? Thank you very much for any information!

With Raid 0, the data is written to both hard disks in parallel, thus increasing the read and write speed. With the 2X4TB system, you also have the full 8 TB available. If it is configured as Raid 1, the data is mirrored. The disadvantage - apart from the loss of speed - is that "only" 4TB are available, but since the data are mirrored, the reliability is increased. This means that if one hard disk gives up the ghost, the data is still available on the second one. This is why Raid 1 is called a redundant system.
