As pointed out in above comment it depends on your requirement. Windows dedupe might serve you well.
On the other hand, dedupe appliances may offer some benefit (may or may not be relevant to you). For e.g. as I understand Windows dedupe will be effective at volume level with current recommended size around 64TB.
In case you have data > 64TB, you will be creating multiple volumes but they will be deduped independently. Dedupe appliances may be able to provide you global dedupe i.e. dedupe across multiple volumes. so that even across volumes only unique data is stored.
