    Sonnet SF3-2CFST reviews

    SF3 Series CFast 2.0 Pro 3 Card Reader is rated 3.3 out of 5 by 6.
    Rated 5 out of 5 by from PHEE-NOM-MIN-AL! For months I had been using a USB 3.0 C-Fast card reader to import footage. To say the process was slow would be an understatement. The moment I plugged the�Sonnet SF3 Series CFast 2.0 Pro 3 Card Reader into the Thunderbolt port of my laptop, it was immediately apparent that my workflow had instantly become much easier. I haven't bench tested the import time to get an exact comparison. However, anecdotally, the Sonnet SF3 appears to be close to 5x-6x faster importing footage from my Canon C300 than the typical USB 3.0 method. If you're on the fence about investing in this unit, it's time to bite the bullet and get it. �You won't be disappointed. �The time savings alone is worth the cost of the unit.

    Rated 5 out of 5 by from Be faster than Codex and Lexar Sure enough, Thunderbolt 3 is much faster than USB 3.0. And it is easy to clean up because it has a built-in cable. Connecting one memory and unplugging or inserting the other will not disrupt usage. The transfer rate is the maximum speed of the CFast. Even if you copy two memories simultaneously

    Rated 2 out of 5 by from Was great! But now I'm not so sure. I've had this reader for about 6 months, and it's been great for me, blazing fast... until today. For some reason, after having it plugged in for awhile, both cards seem to be randomly ejecting and reconnecting every ~ 5 minutes.� I can confirm this isn't an issue with the laptop's connection ports. This can definitely not happen while ingesting. I guess that just because something works nicely out of the box, doesn't mean it has the quality to last.

    Rated 5 out of 5 by from Fast! I mean, really fast! Last week I put the card reader to the test. I filled and downloaded a Lexar�128GB Professional 3600x CFast 2.0 Memory Card. It took 5 minutes and 29 seconds to download (~389MB/s). It was amazing to watch the card download so quickly. Set Up: Connected to a 2016 (late) MacBook Pro via Thunderbolt 3. Pros: Fast, solid (robust construction) and easy to insert and remove cards, and no more cable adapters. Cons: A little bit larger and heavier than a standard reader. Comments:�As stated in publication reviews, the reader does get warm. The Thunderbolt 3 cable cannot be removed from the reader. Initially, I only wanted a single CFast slot or for the second slot to support a CF card. However, as pro cameras continue to move towards CFast the dual slots will be advantageous in the future.��Previously, downloading cards was a significant bottle-neck at sporting events. I do not foresee this as a problem anymore. I will provide an update in a few months.

    Rated 1 out of 5 by from JUNK Thing doesn't work. Used it maybe 4x times and then it stopped downloading correctly. Crashed the computer. From the very beginning had issues when two cards were loaded and never wanted to dismount. Careful

    Rated 2 out of 5 by from Mounting Trouble Lost a card using this. It's fast when it works but my Dell XPS laptop had to be rebooted for every card change, the last time I used it a card corrupted during mounting and I promptly set it on a shelf.
