Hello brdeveloper,
Since the current batch of JetDrives have a SATA III controller with a max bandwidth of 6Gb/s, a Thunderbolt enclosure with a max bandwidth of 10Gb/s would offer minimal speed increases over a USB 3.0 enclosure with a max bandwidth of 5Gb/s. In the future with PCIe SSDs, then Thunderbolt would make more sense.
Hope that answers your question!
Thanks for answering, but actually I think there are other reasons to offer Thunderbolt enclosures. I can see the following benefits of a Thunderbolt enclosure:
- Thunderbolt is lightweight in terms of CPU overhead -- ok, this is a common sense statement and thus the less important to consider when deciding about USB3 or TB.
- A Thunderbolt case would leave a USB 3 port free for additional devices. I use an external monitor through the HDMI port and a Gigabit Ethernet adapter in one TB port. The other TB port is always free. I use all the usb ports with a USB hub for mouse and keyboard and on the other I connect my cell phone.
- A SATAIII SSD connected to USB3 uses the entire bandwidth, that is, you can't plug another device into that port unless you accept that your SSD will run eventually slower than it's capable.
- Lacie sells Thunderbolt external HDDs (e.g. Lacie Rugged). It subutilizes the TB bus, but you have your USB ports free for cell phones (development, charging), home studio audio adapters, printers, keyboard and mouse.
- Lastly, you can charge your TB kits for a higher value!
Anyway, I congratulate Transcend for listening Mac users and creating SSDs suitable for our laptops. However, offering a TB enclosure would bring even more visibility to Transcend products.
