  • Thunderbolt Adaptors?

    Posted by Ken Bennett on May 25, 2022 at 10:50 pm

    I have 2 external RAID-5 12TB drives. One has a Thunderbolt output and the other has a Thunderbolt 2 output. Both currently connect to my iMac 27″ Late 2013 two Thunderbolt ports. On my soon to arrive new Mac Studio, I need to get 2 adaptors going from TB1 to TB4 (USB-C) and TB2 to TB4 (USB-C). Apple (and Amazon) sells these for $49 each. Is there a less expensive brand that can deliver the same thing?

    I’m fairly certain the adaptor is the same for both Thunderbolt & Thunderbolt 2 to TB3/4. I’d stick to Apple adaptors. They’re reliable. Other adaptors I’ve seen are more expensive. Perhaps, you can daisy-chain the two drives if one has two TB ports. That way you’d only need one Apple adaptor.

    I would never go cheap on RAID drives as far as cabling and converters.

    You are just asking for trouble.

    We use the Apple one for all TB1/2 into MacBook Pro M1 Pro.

    I’d start looking at upgrading the enclosures for your two external drives. The Mac Studio has four Thunderbolt-4 ports that can also handle USC-C. Apple traditionally configures two ports per BUS. If Apple has configured the Mac Studio the way they have other Macs, the two ports to the left run on the first BUS, and the two ports to the right run on the second BUS. The BUSes work independently and theoretically can reach their full in/out speed of 40Gb/s as long as the devices connected to them match that speed.

    I’m not sure which Mac Studio you’ve ordered. The M1 Max should have two TB-4 BUSes on the back with a theoretical in/out speed of 40Gb/s and one USB-C BUS on the front with a theoretical in/out speed of 10Gb/s. The M1 Ultra should have three TB-4 BUSes, two on the back and one on the front, all theoretically running at 40Gb/s.

    If you daisy-chain a TB-1 and TB-2 drives together and connect them to one of the TB-4 ports, you’ll only achieve the theoretical in/out speed of the slowest device, your TB-1 drive (10Gb/s) on that particular BUS. If you connect the TB-1 drive to one port on one TB-4 BUS and the TB-2 drive to a port on the other TB-4 BUS, you’ll at least be able to theoretically achieve the speeds of the two drives independently. TB-2’s in/out speed is 20Gb/s.

    You’ll probably have a monitor that will need to be connected to one of the ports. It will run at its own in/out speed and will be a factor on the in/out rate of the BUS it’s connected to.

    I just EOL’d an Areca 8050 T2 (RAID6). It was most recently connected to my M1 Mini through Apple’s TB2-3 adapter, which I’d highly recommend. Get them directly from Apple. Lots of counterfeit junk on amazon.

    Short answer… no. Buy the Apple adapter. Daisy chain the old unit through the new unit if you want to save money.

    I did some digging around about the Mac Studio TB4 ports and buses. All current “M” Macs have one TB4 bus for each port. So, the M1 Max will have four TB4 buses, and the M1 Ultra will have six TB4 buses.
