I have a 240GB Intel 530 with Windows 8.1, used lightly, and have used it since early November.
Using Toolbox 3.2.0, E1 and F1 are 126.19GB. I save download files to a different drive, so that makes some difference. Your Host Writes seem rather high, but you should analyze the SSD's environment first.
What type of PC is the 530 used in? Are you streaming videos, etc, to that PC? What type of downloading do you do?
Are you saving system backups to that SSD automatically, or creating Windows Restore points frequently?
How much free space is on that SSD?
It could be an erroneous reading, but strange it would be isolated to the 120GB models. Have you applied the firmware update to your 530? It should be shown as DC32 on the main display of the Toolbox. This firmware has a fix for a semi-related SMART attribute, but it might affect the E1 value you have now.
The two wear indicators, E2 and E9 have not changed and are the same as mine, that is a good sign.
