Which storage type provides block-level storage?

Block-level storage is a method of storing data in fixed-size blocks, which allows for greater flexibility and performance when managing and accessing data. In this context, Storage Area Network (SAN) is the correct answer because it is specifically designed to provide block-level storage.

SANs operate over a network and allow multiple servers to access storage devices directly at the block level. This means that instead of accessing files as a whole, the servers can read and write data blocks individually, leading to improved performance and the ability to serve many concurrent users without impacting data access speeds.

In contrast, Network Attached Storage (NAS) provides file-level storage, meaning data is accessed as files rather than in individual blocks. This can be simpler for file sharing but doesn't offer the performance or flexibility advantages of block-level storage.

Direct Attached Storage (DAS) refers to storage devices that are directly connected to a computer or server. Although it can provide block-level storage, it does not share the centralized capabilities or multi-server access advantages that a SAN offers.

SATA, or Serial Advanced Technology Attachment, refers to the interface standard for connecting storage devices within a computer. It defines how data is transferred between the storage device and the rest of the system but does not indicate the type of storage
