Points to consider while using custom Settings

Points:
1) Custom settings are a type of custom object. Each custom setting counts against the total number of custom objects available for your organization.
2) The total amount of cached data allowed for your organization is the lesser of these two values:
 a)10 MB
 b)1 MB multiplied by the number of full-featured user licenses in your organization.
3) we can add up to 300 fields per custom setting, unless your field limit for custom objects is lower than 300.
4) We can’t share a custom setting object or record.
5) No owner is assigned when a custom setting is created, so the owner can’t be changed.

Important Tip : When we click on custom Settings,for each custom setting, this page lists the size of one record, the number of records created, and the total size used for each custom setting.
Record size is based on the maximum field size of each field type, not the actual storage that’s used in each field.
When adding fields to a custom setting definition, use the appropriate type and specify a length that doesn’t exceed what’s needed for your data. This action helps you avoid reaching the cached data limit.
Example: if you create a US social security number (SSN) field, select the Text data type and specify a length of 9. If instead you selected a Text Area data type, the field would add 255 characters to the usage count for each record, regardless of the number of characters entered.
