Ultrathin and Ultralight. The X240 long battery life laptop is the thinnest and lightest ThinkPad laptop we offer. Weighing in at less than 3 lbs and measuring 0.8 inches at its thickest point, the X240 is ultraportable — without sacrificing anything in terms of laptop battery life, ports, connectivity, or durability. Sell x240 and buy one of these notebooks many are available up to i7 and two memory slots. Even the newest x series is still 1 slot. Best thing for 12.5' notebooks are with my preferred choices on M.2 slots over mPCIe. HP EliteBook 820 G3 skylake 12.5' 2x memory slots DDR4, M.2 NVMe-SSD OR SATA (requires a 2.5' caddy).

• Re: 16GB memory for X240 #5 Post by jdrou » Thu Jul 24, 2014 9:37 pm With more ultraportable laptops having only one RAM slot available for upgrade I would certainly expect demand for higher-density modules to increase.

I got a few questions regarding upgrade of my X240. I learnt that X240 has 2 slots for M.2 SSD. One is occupied by a 16GB SSD cache drive (this is what I find in my device manager) and the other is for WIFI card. I wanna replace the 16G SSD with a new SSD as windows drive, keep the HDD and upgrade to 8GB ram as 16GB is not supported.
My questions are:
1. Is it any 2242 m.2 SSD with be OK? Which model is crecommended? 128GB or 256GB?
