To anyone buying a Kingston drive for a MacBook Pro (you really shouldn't be considering any other - Apple uses a Toshiba SSD, the V100+ is a Toshiba based SSD, read Anand's review) - you want the V100+. The regular V100 is a turd.
Well, tried a (previous generation) 128 GB V-Series, a 64 GB V100, and a 128 GB V+100, all in my MacBook Pro.
All three worked fine in the MacBook Pro, with no compatibility or speed issues, and I was able to enable TRIM with all three. In fact, in some benches, the fastest of the bunch was the V100, not the V+100.
However, I returned the V100 and V-Series. Although they worked fine, both used a lot of battery power. I was a little surprised at the power usage of the V-Series, given Anand's review:
However, it turns out the 30 GB version of the V-Series is a special one, specifically optimized for low power use as a boot drive. In contrast, the 64 GB and 128 GB versions (the latter of which is the one I tried) are total power hogs. That was not obvious from the Kingston website, until you go to the
right page. Their
other page (which unfortunately was the one I checked when I bought it) doesn't separate the power specs for the various models. Too bad since a 128 GB model with the power characteristics of the 30 GB model would be totally awesome.
So, in the end, as you suggest, I stuck with the V+100. I didn't do formal battery life tests, but it does seem decent with that one. FWIW,
this review compares the 96 GB V+100 against a 7200 rpm 200 GB Seagate Momentus drive. With the V+100 their laptop gets 158 minutes of battery life, vs. 137 with the Seagate, a difference of 15%. Their
200 GB Momentus 7200.2 is 0.8 Watts idle and 2.3 Watts active. That suggests to me that at least for some usage, the V+100 probably isn't that much different in terms of battery power compared to a regular laptop 5400 rpm drive, despite the V+100's much lower idle power. The V+100's much higher active power removes any advantage the low idle power provides.
BTW, when you install the V+100, TRIM doesn't get enabled in OS X automatically. I had to use TRIM enabler to activate TRIM. (I figured that since this is likely similar or the same drive as Apple's own, and Apple activates TRIM on their own drive, then I'd be better off keeping TRIM on this drive too despite its aggressive garbage collection.) I suspect it's because Apple has a custom firmware for their SSDs. This is in contrast to some of their optical drives. Apple has custom firmwares for those too, but if you stick in an optical drive of the same model with a non-Apple firmware, the drive would often get recognized as a native Apple drive anyway.
