Fast shipping and great packaging are always a priority for us, and it's wonderful to know you appreciated that. Your recommendation means the world to us! Enjoy your new drive!
The case is rugged and light. Usb c connectivity is great for future compatibility. I have a micron sata ssd inside, but transfer speeds are about 380 Mbps, closer to the 5 Gbps limit of usb3 gen 1 than gen 2. Crucial reports 550 Gbps for the drive. I have M1 MBP with thunderbolt 4 ports.
