Yes, though it varies by particular disks.
smartctl -a /dev/whatever produces SMART data which may include
things like:
233 Media_Wearout_Indicator 0x0032 002 002 000 Old_age Always - 0
or
241 Total_LBAs_Written 0x0032 099 099 000 Old_age Always - 7395041209
or
177 Wear_Leveling_Count 0x0013 099 099 000 Pre-fail Always - 4
Each of which tells you relevant things without being perfect
predictors.
