Kingston KC600 SSD SKC600B/2048G Internal SSD 2.5 Inch, SATA Rev 3.0, 3D TLC, XTS-AES 256-bit Encryption - with Upgrade Kit
But if you are talking about intense Web Servers and fast databases. I'd be looking at a RAID drive or multiple RAID drives over a fiber optic interface.
And if your talking mission critical,. Yeah, multiples of everything (Laptops) and think LINIX.
For me, just wanting speed out of Windows. My SSD and some tweaks on my cheap Aspire 5 are heaven. But I cheated you see. Bought the Laptop with the SSD already in it and built for it and it shows.
So you might want to think of another Laptop with 2TB SSD already installed. Good grief, they come multi-core these days anyway.
Depends on what you are doing and where you are going with your setup.
