I haven't really shopped for SSDs before but I need to upgrade my 4 year old MBP. It looks to be about $20 cheaper than what's on Newegg:

I'm not sure if the "trim list" link in the article (libdata-core.c) is current or not, but it's worth reading:

Unfortunately, the product name "CT512MX100SSD1" in your Amazon may not match what the device actually reports to the OS.
BTW, there's also a section of 30%-off items—mostly clothes and luggage—that doesn't seem to have the "lightning" quantity limits. http://www.amazon.com/b/ref=pin15_us_gw_d_p3_ld_softlines?_e...
They're now an Amazon property, but they're still cheap and convenient.
I probably would have grabbed a paperwhite if they'd reduced it with the cheap kindle.
Yeah, they really dropped the ball on this.
