Would there be any disadvatage to upgrading from small SSD+large HDD to a single large SSD?

When Maxwell came out, I knew it was time to upgrade, and there is no question that I'm upgrading to an Asus G751.
But I've always hated the small SSDs that came with the laptops, I always have a lot of crap on my main hard drive (which is the SSD on my G750) and it's annoying to have to chronically delete files, uninstall games to fit new ones, or simply move big files around as my 1TB Toshiba hdd can't handle nearly the amount of data transfer that the 240 GB Mushkin SSD can.
So this time around I plan to buy the cheapest $1499 G751 with only a spinning HDD as well as a 1 TB SSD (probably a Samsung 840 Evo), replace the HDD with the SSD and sell it. Are there any real disadvantages in terms of gaming, or CAD (I use ANSYS for engineering stuff) of a single big SSD setup versus my current one (240 GB SSD and 1 TB HDD)?

 

No disadvantage other than you'll lose 240GB of storage space. Just keep in mind that if you sell the HDD and have to send the laptop in for warranty repair that you risk losing your SSD. Since you likely won't get much money for whatever 1TB HDD they put in your laptop ($50-60 tops), better to keep it so you can swap out when you send in your laptop to be fixed.

 

The main downside will be that everything is on one drive, so you lose it all if one drive fails (as opposed to losing just your OS and retaining data, or vice versa (assuming you put OS and programs on one drive and user data on the other).

 

Put the 1 TB HDD in a USB 3.0 enclosure and use it for storing backups.

If your looking for something powerful and cheap and also with free acronis software to clone your old hard drive to the new ssd...

i can't say enough good things about the crucial mx100 500gb ssd.... freaking amazing and regularly priced at around 180ish... it is a beast of an ssd too and the 4K values it gets means that in alot of real work performance use it is even slightly faster than the samsung 840 pro.

 

As mentioned above, the only real disadvantages are a single point of failure and the added expense of a large capacity SSD. Follow John's advice to periodically backup to another drive, and the only disadvantage is the higher overall price tag. Larger capacity SSDs inherently last longer (based on write erase cycles) and typically outperform smaller capacity SSDs. They're also more economical in terms of price per gigabyte. And almost any current SSD is going to be much faster and much more reliable than a hard drive.
