Question Waiting for the MP510 SSD

[D3K1DS]

So I've been waiting a while for the Corsair MP510 to be back in stock. Should I keep waiting? Honestly, I don't know how good the SSD is. Also, should I get another drive? This build I found only has one drive (the MP510). My current build I have 2, one for windows and all that (normal Hard Drive), and the other is the SSD with all the games and software. Should I get another SSD with this build? Or maybe just a normal Hard Drive or a cheaper SSD. This is probably a dumb question haha

There are multiple other similar drives.
Samsung 970 EVO, for instance.
