Benchmark Results: Power Consumption
Power consumption is very relevant for laptop users who intend to get an SSD as a replacement for their hard drive. As a general rule, SSDs are lower on power when it comes to idle power (active idle) with a few extreme examples from Crucial, Intel, and Toshiba. The other power consumption results were tracked at specific workloads, which makes more sense than trying to hunt down one peak power consumption number you'd never encounter in real life.
The undisputed lowest-power drives, at idle, are the Intel X25-M models and Toshiba’s HG2. Crucial’s RealSSD C300 is great as well, but only when discussing the low-capacity 64 GB model. The 256 GB flagship requires much more power in active idle.
Streaming read power consumption reflects the power the drive needs to deliver data at peak throughput. Once again, Toshiba operates at an amazing 0.5 W, followed by the SandForce-driven SSDs. Western Digital’s Silicon Edge Blue and Crucial's RealSSD C300 require the most power here. The Crucial drive delivers bone-crushing throughput, while WD is just one many drives in the 200 MB/s realm.
Enthusiasts need to know how much power an SSD requires when delivering a 1080p video stream, as this is a popular workload. Once again, Intel and Toshiba are unbeaten, requiring half the power of Indilinx drives or the WD SSD.
The workstation test involves heavy I/O activity and stresses SSDs in a much different way. Toshiba's drive, which is the lowest power consumer at idle or when delivering massive amounts of sequential data, is a real loser at high I/O activity. The Indilinx drives are lowest on power consumption under intensive I/O, but they also don’t deliver the same level of performance as the SandForce SSDs. Let’s look at how this translates into power efficiency.

Where are you getting your prices for the Mercury Extreme? On OWC's site, they list the 120GB Extreme Pro for $319, and the 100gb Extreme Pro RE (RAID ready, with more overprovisioning) for $369. Not the 399 you mention. The most fair comparison is the 120GB Extreme Pro, which I just purchased for my laptop, and its price is just about in line with the other Sandforce drives out there. plus, you get OWC's awesome warrantee, which to me is worth the extra 20 or so dollars.
>_> i just ordered a crucial c300 64gb lol
It had to be done, i've been waiting ages to get one and tbh i got it for £108 which is nothing compared to a mobo/processor upgrade but will deliver so much more performance.
Its only small but i have 2TB already for storage, i just need something quick for windows
On the second page you write the following:
"You can recognize these both by the performance discrepancy between reads and whites and by the exterior"
Shouldn't that have been "write" rather than "white"? Just a small nitpick, thanks for doing this roundup!
Did I miss something? Why do we have the Kingston drive in the final tables but not in any of the tests?
Strange, I keep getting emails saying there's a new post but can't see any new post here. See below:

It was a spammer that got nuked.
I admit I skipped straight to price/performance charts. The text mentions SandForce SSDs, but this name is not on the graphs anywhere, which is a bit troubling. Yes, my lazy eyes will search the article again for the correct relation between fantasy name and manufacturer. Another nitpick.
...But what the hell, the Crucial drives show up on the top 1/4 of all the graphs that matter. I smell a Christmas gift for myself coming up...
Or maybe it is VERY late, and I am VERY sleepy. Otherwise the Crucial's C300 FTW.
GoneMad: they are referring to the Sandforce controller the different SSD's use
which is better then the other controlles some SSD's use so check out each drive which controller they use and you figure it out
