I recommend kingston for value SSD. Samsung is great, but the price is too much for average user in my area. With kingston i never face problem (i install plenty of it on my customer pc/laptop) and never found 1 faulty drive for nearly 3 years. for the type, i suggest sv 400 for the price/performance. It cover 5 years warranty too, which i find nice.
for low budget, i prefer SP (Silicon Power) better than sandisk, based on my experience too.
