There's a bit more to it than that (see the Intel link above).
It's easier for those like the 320 designers who don't need to compete very hard on cost and performance but otherwise, there's a balance to strike: some writes consume a lot more power than others ("amplification") so it would be wasteful for drives to pack enough power for the worst case scenarios (or enough spare capacity to effectively rule out these worst cases) when they're not required to have a high performance at all times. Making sure such a cost-efficient design works as intended is probably not trivial.

Seems like an extreme corner condition. In this case, you are really saying "I can't be trusted to monitor the battery life of my UPS, so please let my SSD have a safe shut down mechanism". That said, I really need to check the condition of my UPS :)

Heh.
The batteries were 9 years old, while they should be replaced every 3 years. I left them because the APC in these 9 years coninued to work giving me no anxiety... until the last black-out. I didn't install the Parachute manager software so during the last blackout after 4-5 minutes the UPS died suddenly... after I was able to restore my system functionality I bought a couple of new batteries and installed immediately the APC manager software. Even with new batteries and the software running makes a lots os tantrums... so surely every PC should have a good power supply and an UPS but if even the SSD has some black-out protection is a good thing!!!
