Second hand ssd

[Sukh]

What sort of assurance should one look for when buying a second hand SSD?

Is there some sort of health check that one can perform?
Also which drive should I lean towards:

Vertex
c300

or buy a new sata3 drive?

I already have an M225 64gb, but it is getting full and I want to run bf3 from an SSD.


Thanks

So what is the biggest drive that utilises sata3 for 120 ex vat?

Is sata3 worth an upgrade or are sata2 drives much cheaper and in percentage terms not that much slower?

Are the Intel drives still the best bet?

So shall I go Intel or crucial?
