My experience is that consumer grade SSDs don't last all that well - I want drives that will last for longer than I expect a laptop to last - my current (consumer grade) laptop is 5 years old and is on its second main drive - I'd gone for a machine with a consumer-grade main drive; my previous laptop was used for both work and home for 5 years (far more intense usage than the current one) and then as only my home laptop for 5 years after I retired (until I wanted to upgrade to Windows 8) and for the last  4 years has been used intermittently for games that don't run on Windows 8 or anything later, and still has its original main drive - it is an enterprise grade laptop including an enterprise grade main drive.   I've used consumer grade drives for backup, not particularly intensive use, and even there they generally don't last long.
