I'm in the market for an SSD, but I haven't found any information on which SSDs do NOT use compression on the controller.
The system it will go into requires full disk encryption (provided via LUKS), and many (all?) of the Sandforce controllers end up crippled when they can't compress writes.

SSDs using Marvell's 88-series controllers don't use compression. See here for a recent round-up which includes many models/suggestions. Note that Intel's 510-series SSDs also use(d) Marvell controllers, but the newer 520 series uses Sandforce.
Samsung SSDs, using their in-house controllers, also do not use compression.

Hi Alex, welcome to SuperUser.com. Full disk encryption has known issues with SSDs. Also, this is treading a fine line with "buying recommendation", which is specifically off-topic for SuperUser. – None – 2012-08-23T19:42:19.620
3Since the question is asking about controllers, which are typically used by multiple manufacturers/models, and not "Which SSD should I buy?", I'd say it falls on the on-topic side. – ish – 2012-08-23T19:44:55.680
I agree, which is why I didn't vote to close :-). – None – 2012-08-23T19:46:59.270
