May get some diverse opinions as to which way to go because there is no right or wrong answer. It is a great question for how different folks set up their systems.
In general the newer HDD's will give average (Read/Write) speeds of 50-100 MB/sec, say an average of 75 MB/sec
Using RAID 0 gives you a speed of x times the # of drives - 2 drives give you 2 times the speed, say (150 MB/sec) but no fault tolerance (1/2 the reliabiity).
The RAID 0 drives can be problematic to set up, and if you lose one, you lose all the data stored on the RAID volume.
The SSD speeds depends on which one you have or plan to buy. Recently in Max PC Mag they tested the latest SATA 2 & SATA 3 SSD's
OZC SATA 3 Vertex 3 was 506 MB/s reads, Intel 510 SATA 2 was 480 MB/s reads, Plextor M2 was 387 MB/s reads.
If you want to be very scientific about it, you can measure HDD speeds like your Samsung F3 using small applets like HDTune, or DiskSpeed, and the SSD speeds by AS SSD or CrystalDiskMark. You may not want to get into it at that depth!
I would probably use a SATA 3 SSD for your primary drive and the Spinpoint F3 as a secondary drive, however the SSD's are more expensive.
