yeah, msata prices are quite exp. Unless you buy from US and ship it in.
i ordered my 256gb msata direct from crucial.com using hopshopgo paypal promotion, and shipping cost me about $5SGD for express shipping
i also ordered my Y580 from the U.S during Black Friday Sales and it took about 3 weeks for it to arrive in SG.
[FHD, 1TB, Blu-Ray Burner, 8GB RAM @ $899USD+99USD (SGD$1264) for 2 yr Depot+Accidental Damage Protection] add another $150SGD for shipping, it is relatively cheaper.
All in i paid about $1400SGD,and using the savings i got i used it to buy the 256GB msata. so all for $1699 or less... i got a maxed out y580. whats left is to see if 8gb ram is suffice for my usage...
