What do you like best?
Datto NAS is a simple functional NAS device that allows you to backup both locally and in the cloud for a very fair price. It is easy to remotely administer the device so most often troubleshooting the few and far between issues can be done without an onsite visit to the client office. The Datto Drive Integration is important as it allows users outside of the local network to access shares.
What do you dislike?
There are not as many protocol options as some NAS like Synology may have. The Active Directory integration could also use some work. I have seen two occasions where the AD integration completely broke leaving the users having to use a public share or use local device logins to access a share.
Recommendations to others considering the product:
Set up your shares carefully and definitely check to make sure the security settings you have match what you are trying to do. use the active directory plugin to make permissions easier but do be aware that the AD integration is prone to fail. Do use the Datto drive option so that users can access the shares from outside of the company network. Set up is easy and automated so there should be no problem getting it up and going.
What problems are you solving with the product? What benefits have you realized?
many small businesses without a need for a full blown server do well using a Datto NAS as a small file server. they are able to create network shares and use the shares even from home. Integrated local and cloud backup makes it doubly useful and convenient.
