I'm pretty out of date with this stuff, I've tried sifting through some review sites the past few days but I am having difficulty sorting it all out TBH.
Q1: Essentially, I was looking to upgrade I/O a bit by investing some in the Z77 SSD Caching method on my existing PC. I have a 3TB main drive with everything on it right now. My idea was to buy a 120GB or so SSD as use it as my cache drive. I know that it tops out at 64GB or so for the cache, so I assume the other space will just be wasted, but I really did not have the time nor the inclination to re-format and re-install the OS and other things now.
However, has anyone tried this SSD caching method before? Are the results comparable to running everything from an SSD? I must admit, I really like the idea of not having to manage the stuff that is on or off of the SSD, the caching algorithm will take care of all of that. I can't possibly justify the cost of a 512GB+ SSD, so it seems no matter what if I use it as my primary drive I will be installing/uninstalling things on it to manage what is fast and what is not. Having the OS do this for me automatically instead, even if it is a slight performance penalty is... appealing. Heck if that is the case maybe I can even save a bit of money and buy a smaller drive and forget the eventual reformatting altogether.
Q2: In that vein, what are some good SSD's to do this with? From what I have read the Samsung 840 is a good price/performance deal right now. I am concerned though that Samsung rates it for "only" 1000 program/erase cycles. Is this an issue to be worried about? The Adata SX900 seems to be on sale in my area right now and the paper specs look good, but is it a decent drive? I have trouble finding good reviews on it, is it something to avoid?
Q3: For SSD caching, is it worth it paying the extra for a "performance" drive vs non? For example the price difference between the Samsung 840 and 840Pro is about $30. I'm understanding that the 120GB drives are more run-of-the-mill while the 128GB are "enthusiast" models. Is that important for SSD caching?
Q4: Last one; I was going to replace my old Razer Abyssus at the same time. I wanted something with more buttons. I was eyeing the Roccat Kone XTD, but oof that price... but then I see a Corsair M90, I guess an older model, being dumped for $29 (regular $79). The M95 is one of the reccomended mice in the OP, I am assuming it is the reason that M90 is being slashed, but is the M90 worth getting?
