I really like the Phison S8 controller and have one in a notebook I use a few times a week. Somewhere along the line, I had to see for myself if the low queue depth IOPS performance was as impressive in real life, as it is on benchmark charts. For everyday use, the drive works really well and the performance is smooth. The only issues I ran into was installing a lot of software and writing to the drive hard.
Phison reduced the write latency on the S8 controller several months ago, so day-to-day computing is very fast. Windows updates take more time than say a Force GT or Samsung 840 Pro, for example, and that's about the only time when you'll really notice a large difference with this value based SSD.
Corsair doesn't plan to bring the Force LS to the USA market and that's too bad. The MSRP prices shouldn't hold up for too long regardless of the market and I think the Force Series LS will eventually become an excellent low cost, good enough performance SSD, for those looking upgrade an existing computer with an SSD.
We did notice a difference between the notebook battery life with the Force Series LS and the other Phison S8 drives we've tested. The firmware has changed so we suspect the difference rests entirely in the firmware. The Force Series LS 240GB still delivered very good battery life, but in our test, the new firmware shaved off around 10 minutes of power on time.
