Well, looks like Anand actually
reviewed this drive... sort of. That's the newer version, with updated firmware; performance should be improved, but power consumption probably won't.
Excerpts (Emphasis mine):
"We reported drive only power consumption in three scenarios: idle, during sequential writes and during high queue depth 4KB random writes. At idle the V+100 does incredibly well, but under load it is one of the most power hungry SSDs we've tested. As bad as that sounds we're still talking about half of the power usage of a 600GB VelociRaptor, but
in a notebook don't expect to save any power under load - only at idle."
"And there's one phrase in Kingston's press release that sums up why Apple chose this controller for its MacBook Air: "always-on garbage collection".
[...]
The benefit of this is you get peak performance out of the drive regardless of how much you use it, which is perfect for an OS without TRIM support - ahem, OS X. Now you can see why Apple chose this controller.
There is a downside however: write amplification. For every 4KB we randomly write to a location on the drive, the actual amount of data written is much, much greater. It's the cost of constantly cleaning/reorganizing the drive for performance. While I haven't had any 50nm, 4xnm or 3xnm NAND physically wear out on me, the V+100 is the most likely to blow through those program/erase cycles.
Keep in mind that at the 3xnm node you no longer have 10,000 cycles, but closer to 5,000 before your NAND dies. On nearly all drives we've tested this isn't an issue, but I would be concerned about the V+100. Concerned enough to recommend running it with 20% free space at all times (at least). The more free space you have, the better job the controller can do wear leveling."
In other words, for a laptop user:
1) You'll probably see an increase in battery life, but only if you don't stress the HD/SSD with I/O intensive tasks.
2) Keep as much free space on the drive as possible, and do as little writing/overwriting as you can.
The first concern isn't a big deal, but the second... yeah, that's a worry.
