"While Thunderbolt 3 ports are guaranteed to supply up to 15W for client devices, USB 2.0 ports are guaranteed to deliver only 4.5W (900mA @ 5V)."
USB 2.0 ports are only guaranteed for 2.5 W (500 mA @ 5 V). 4.5 W is for USB3 ports, although USB 3.2 Type-C ports in dual-lane mode must support at least 7.5 W (1,500 mA @ 5 V). Also, for Thunderbolt 3 ports to deliver more than 4.5 W requires the connected device to support USB Power Delivery.
Thunderbolt 3 ports could also support 7.5 W (1,500 mA @ 5 V) and 15 W (3.0 A @ 5 V) via USB Type-C current advertisement, but that would be implementation specific. I wonder how broadly supported that is, or if there are any devices that can take advantage of it?
Why are these drives so wide and bulky compared to the current crop of NVMe M.2 2280 to USB-C 3.1 enclosures? The SanDisk is almost twice as wide as my Plugable (sic).
Maybe old habits. It seems easily construed as a familiarity aesthetic with previous generation pocket-sized portable drives. You made me look up NVME enclosures and now I'm woke enough to consider one for personal use.
So whatever happened to 20Gbps (USB 3.2 Gen 2x2) - we saw the ASUS U32 20G enclosure reviewed over a year ago hit 2GB/s but then never hit the market (at least not the US market)
Not sure if the WD division has as good support, but one advantage is also just how great SanDisk's support it. Had an Extreme Portable 510 that died a bit after warranty ran out. It was weird - from one moment to the next it stopped being recognised entirely. Even though it was past warranty, SanDisk sent me a box to ship it back to them in and I promptly got a replacement unit
