Hi, i'm building a new system and would like to know if its better to have a 500gb SSD and have the OS plus applications and games installed on it or buy 2x 250gb SSD's and have one for the OS and the second for Applications / games.
Or alternatively buy 2x 250gb and set them in a Raid 0 and have it all in one place. The drives im looking at cost pretty much the same for 2x 250 compared to 1x 500gb

Either way il put personal data files on a different drive so this is just a question about OS and Applications / Games.


Many thanks.

From the article he quoted

As expected, the RAID 0-based setups, consisting of two 128 GB and two 256 GB SSDs, solidly beat the single-drive configurations in our sequential read and write test. In fact, the two striped 256 GB drives provide about twice the performance of the single drives.

I always have Been a fan of raid setups and I am even Moreso now that storage is no longer mechanical. It's worth mentioning u will lose the ability to use rapid dram cacheing if your going with EVOS. It's an extremely fast tech but it's hit or miss.

Either way it's going to be plenty fast with little discernable difference. Ultimately depends on what you intend to use it for and your current situation.

(For example my backup PC has a 120gb...

Thanks for the quick response :)

If using one large SSD would it be better to create 3 partitions on it? One for the OS, one for apps and games and a 3rd for the Page file or just leave it as one partitions using the whole drive?

Il be putting in 32gb RAM so i guess that wont be a problem, it will also have an i7-4930k CPU so should be pretty fast.

So to sum it up just go for a 500gb SSD looking at the Samsung 500gb 840 EVO and have OS, Apps / Games and then drop the pagefile down to something small.

Again its better to do this on one 500gb drive rather than 2x 250gb set in RAID 0?

Yes. 1 x 500GB is equal to or better than 2 x 250GB.
Here's a test on exactly that question:

(For example my backup PC has a 120gb ssd and I'd be damned if I bought a 250 to rep it with as opposed to adding another 120gb.
