You can run ZFS on Linux via FUSE. This would probably achieve exactly what the OP is looking for.

Software SSD Cache Implementation For Linux? 297
Annirak writes "With the bottom dropping out of the magnetic disk market and SSD prices still over $3/GB, I want to know if there is a way to to get the best of both worlds. Ideally, a caching algorithm would store frequently used sectors, or sectors used during boot or application launches (hot sectors), to the SSD. Adaptec has a firmware implementation of this concept, called MaxIQ, but this is only for use on their RAID controllers and only works with their special, even more expensive, SSD. Silverstone recently released a device which does this for a single disk, but it is limited: it caches the first part of the magnetic disk, up to the size of the SSD, rather than caching frequently used sectors. The FS-Cache implementation in recent Linux kernels seems to be primarily intended for use in NFS and AFS, without much provision for speeding up local filesystems. Is there a way to use an SSD to act as a hot sector cache for a magnetic disk under Linux?"

You said you find bugs and report them so they get integrated back into the kernel. Is that a specialty of OSS, or do you also get this with other proprietary products?
Well you can find a bug in a proprietary OS - meaning you have a reproducable malfunction of the OS - but that's not the same as identifying the line of code that's causing the malfunction, changing the source code, testing that the change actually solves the problem correctly *in your environment* and then submitting the fix back to your supporting vendor.
No you certainly can't do that with a proprietary OS. The move to Linux on Wall Street was largely driven by the decisions of CTOs looking to reduce the bottom line by moving towards commodity hardware (as others have mentioned here), BUT all the geek engineers on Wall St. love the practical aspects of working in open source. Some of us love the philosophical aspects of open source too!
as in
-as easy to identify bugs
-no problem contacting the right people (developers)
-bugs getting fixed on a reasonable timescale
