The only option is a 2.5" SATA SSD.  They're pretty much commodities -- any of the big names (Samsung, WD, Crucial and plenty of others) will do fine.  
Hi Im looking to upgrade to ssd for the first time? Was looking for suggestions and wondering if I should get sata, and if m2 is even an option?  Where is the best place to aquire parts/upgrades? Any suggestions is appreciated... For typical daily use , no hard core gaming/streaming, want to see/experinence how a simple upgrade feels compared to this hhd on old laptop. Thanks   the only specs i could find for my device... Interface           SATA 6 GbpsHard drive       One 2.5‑inch drive (supports Intel Smart Response Technology)
