Bests & Worsts Reviews from Amazon

So this laptop can apparently come with two different types of hard drives (both 256 gig ssds). If you buy this laptop, you will either get the Sandisk U100 or the ADATA MX11. An uninformed consumer probably wouldn't know or care what the difference between these two drives are, but they should! The Sandisk U100 has the worst write speeds of current SSDs. The Zenbook prime I ordered was horribly slow at transferring files because of this. When I took the laptop back to the retailer, I requested an exchange for one with the ADATA MX11 hard drive. I was told by the retailer that there is no way to tell which hard drive you will get without opening the retail packaging. Note that opening the retail packaging renders the product used. I feel Asus should put the hard drive brand on the outside of the box so that consumers can make a proper informed decision. The ADATA MX11 outperforms the Sandisk U100 in every way and this can be seen in performance tests when comparing the two. I would not recommend anyone purchase this at this time. At least until Asus is more forthcoming about which SSD they are putting in this Zenbook. Update. Well I must say this has been a pretty horrible experience, and I'm never buying an Asus product again. The screws on the laptop keep falling out. I am now missing 2 of them and the only way to get them replaced is to ship it to Asus. I any afford to do that as I need to have a computer for school and work. The hard drive performance is painfully slow, and of course Asus won't replace the drive. My best advice to anyone thinking of purchasing this device or any Asus product is to avoid at all costs.
