Object Storage

Object storage is a computer data storage architecture that manages data as objects, as opposed to other storage architectures like file storage which manages data as a file hierarchy, and block storage which manages data as blocks within sectors and tracks.

Note: "Object storage is an alternative to NAS for handling unstructured data. There is speculation that object storage gradually will overtake scale-out NAS, but it's also possible the two technologies will continue to survive side by side. Both storage methodologies deal with scale, only in different ways. Object storage surfaced as a new method for easily scalable storage in web-scale environments. It often encompasses unstructured data that is not easily compressible, particularly large video files."


Block Storage (SAN / "Structured")

File Storage (NAS / "Unstructured")

Object Storage ("Unstructured")

Object Storage examples: AWS S3, Azure Blob, Google Storage, Wasabi, MinIO

Object storage systems allow retention of massive amounts of unstructured data. Object storage is used for purposes such as storing photos on Facebook, songs on Spotify, or files in online collaboration services, such as Dropbox. Object storage maintains availability by storing multiple copies of data over multiple nodes through a replication process. If one node fails, the data is still available, and no downtime is experienced.

Advantages of Object Storage...

You can't use object storage services to back a traditional database, due to the high latency of such services. Object storage doesn't allow you to alter just a piece of a data blob, you must read and write an entire object at once.

The storage can be addressed with a few commands:

NEW! Veeam: How to deploy QNAP QuObjects to have an Object Storage on-prem and use it as Capacity Tier

Why is SSD not a good option for long-term storage/archives?

"Long term? No. SSDs store data in “floating gate transistors.” These transistors have a gate surrounded by insulator. A weird quirk of quantum physics means you can get electrons to “tunnel” onto the gate, passing onto the gate without crossing the space between, and then, since the gate is surrounded by insulator, the electrons remain trapped there.

However, the same weird quirk of quantum physics means that every now and then, an electron will tunnel right back out.

If you take an SSD, record files on it, and sit it on a shelf, over time the data on the disk will slowly evaporate. Come back in five years and the disk may be unreadable and all the files corrupt.
