I chose a PNY CS1111 series 120 GB drive. It doesn't have the fastest read speeds, but it's faster than 3 Gbit/s SATA or 1x PCI Express 1.x, so the GA-P35-DS3R motherboard is the bottleneck.
According to PNY's 2015 SSD Product Comparison PDF, the CS1111 series uses a Silicon Motion SM2246EN controller. However, the SMART attributes don't make sense as SM2246EN attributes, and make sense as SandForce attributes. For example 241 and 242 are definitely measuring gigabytes. So, is PNY's information wrong? Are there multiple versions of this drive with different controllers? PNY's support didn't answer. I don't feel like opening up the drive to see if there's a SandForce controller inside, because that would void warranty. Here are the SMART attributes, as reported by smartmontools.

The PDF you linked has been updated (Apple Preview shows that it was created on October 5, 2015), and it now shows the CS1111 as a Silicon Motion SM2246EN drive. The only PNY drives listed as SandForce are the 120-480GB CL4111 and the EP7011.
Your drive's SMART attributes also look very similar to those on my 480GB CS2111, which is also listed in the PDF as an SM2246EN drive. (I haven't used the drive much so I don't really have an opinion on it. Well, except that MacBook screws don't seem to fit properly into either my CS2111 or my 240GB PNY Optima, a problem which I never experienced with any other 2.5" SSDs, so I'll keep the drives for use in my PCs but I'm not likely to buy any more 2.5" PNY SSDs.)
In September I tried to use this drive in a different computer which had a miswired SATA power connector, with ground connected to 12V. This damaged the drive, so I ended up opening it up and saw that it indeed has a SM2246EN controller. I'm not sure why the SMART values are a closer match for SandForce. That's probably due to the firmware.
I ended up fixing the drive and am still using it in my laptop. Mounting it there was a bit of a problem. It was interfering with the cover on the hard drive slot, and even after modifying that, it still doesn't fit perfectly but it's good enough. The WD Blue drive that was there before fit perfectly. It's as if PNY has been careless with case dimensions and precision.
