I emailed SanDisk support, linking to this thread. They responded saying that it’s a known OS X issue, but I’m not totally sure of that as many of the links they sent are for years-old unrelated issues. I might try calling to see if that gives better results, or perhaps Apple just to see if perhaps it is a known issue and the support tech just didn’t have the full background.
And, this wouldn’t explain any of the trouble people are having on Windows. Here’s the response I got:
Thanks for emailing SanDisk Technical Support. It is our goal to make sure you have all the resources you need to get the most from your product.
I apologize for the inconvenience this may have caused. I would like to inform you that it is a known issue on MAC OS X 10.9.1 OS. There are a lot of customer’s facing the same issue on MAC OS X 10.9.1 which is also posted on multiple MAC forums. Please refer to the below mentioned link:

This issue is not specifically related to SanDisk SSD as there are multiple users on the Apple forums who are facing issues with HDD and SSD drives as well. Apple is already aware about this issue with the operating system. I would request you to contact Apple to find if they are planning to bring a new update for the OS.
