Use this SSD for C# development with 8GB (2x4gb) 800Mhz RAM. It blows away many other desktops.

The Samsung evo series is very fast. The reason why I break 1 star is that it is 120 gb, my phone is 120gb, but I recommend the 240 gb version.

Best bang for buck & cheap (120Gb) SSD. I love the Samsung Magician software.

Samsung - no rivalers - in SSDs. But in SATA SSDs - Samsung versus HDD-ish WDs, then high prices make Samsung a near-loser, Koreans still wins. If you have an crappy laptop, I recommends this.
