Hashtable

[delphi.com.ar]

Muchachos, no quiero parece repetitivo, pero en el link que le he recomendado habla también del uso de TStrings

Although TStrings provides similar functionality through its Values[] property, this is not a good choice. TStrings doesn't use hashing, so finding an item is an O(n) (slow for lots of data) operation, whereas with a hash it is normally O(1) (same speed regardless of the number of items).
