Just bought one of these (Acer es1-332) myself, got it cheap from Argos outlet £119.
Storage is poor so I have ordered " hdd cable 50.GFZN7.004 "
£28 from germany this will allow me to add a ssd which I already have and boost this little netbook with some much needed storage space.
Hope this helps.
Update : 25 July, HDD cable arrived , two minute job to connect cable and ssd.
Cloned old emmc hard drive to ssd ( using reflect)
Entered BIOS F2 on start up changed boot device priority to new ssd hard drive.
