I can't confirm that the Intel 330 is more reliable, but even if that is so the Samsung 830 is still very reliable and better than most other SSD's.
Unless you can confirm that the Intel 330 is more reliable AND similarly priced get the Samsung 830.
I usually recommend a setup like this:
a) 128GB Samsung 830 (about $100) for Windows/apps
b) Hard Drive for:
- Image Backup of the SSD (Windows drive)
- Steam game folder
I use Acronis True Image, but WD and Seagate both have a free version available so you can make a backup IMAGE of your Windows drive. Use the HIGHEST compression settings to save space, or second highest with a slower CPU.
