CONCLUSION

   After wrapping up all our tests and comparing them it's not hard to see that the Slim S55 is a good improvement over the Velox V55 across the board (with some exceptions of course) but certainly not enough to justify going from the V55 to the S55. That being said i was expecting PHISON to come up with something new and improved by now since their PS3108-S8-I SATA-to-Flash 8-channel micro-controller is not really new on the block but it seems that with the help of some firmware optimizations they have managed to further push its performance to a point where it can keep up with all the latest models wearing Samsung, LSI/SandForce and Marvell controllers.

   If there's a serious drawback with SSD models by Silicon Power that's their availability and so although you can easily find the Slim S55 240GB model for USD167 inside the USA (Amazon.com) the same doesn't really apply for the EU since i was unable to locate it anywhere, at least not online. The price tag is also not what one would expect from an SSD model using the PHISON controller especially since for example other similar models like the 840 EVO 250GB by Samsung or even the M550 256GB by Crucial retail for slightly less. I'm not of course saying that the price is bad but i do think that Silicon Power has room to cut it further and with the current level of competition in the market i hope they do so soon. Still performance is quite good (obviously a step up from the previous V55) and the price is almost right so we strongly recommend taking a look if you’re out in the market for your first or a new SSD.
