Oneplus 5t comes with 128 gb of rom and 8 gb of ram. It is same as oneplus 5. There is not much improvement seen in 5t as compared to oneplus 5.Only there are little improvements such as performance is same of octa core, camera, sensors, android version etc. So guys I recommend you that upgrading to oneplus 5t is not so good wait for oneplus 6t. But it is good for fresh buyers.
