Simultaneous data transfer and error control to reduce latency and improve throughput to a host

A system for transferring data from a storage device to a host, comprising:

• a communication mechanism, configured to:
• receive a request to read a set of blocks from the host;
• transfer each block from the set of blocks over an interface with the host upon reading the block from the storage device;
• an error-detection apparatus configured to perform error detection on the block upon reading the block;
• and
• an error-correction apparatus configured to perform error correction on the block if an error is detected in the block, wherein the communication mechanism is further configured to retransfer the block to the host after the error is removed from the block.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor included in a computer, cause the computer to carry out steps for transferring data from a storage device to a host, the steps including:

• receiving a request to read a set of blocks from the host;
• upon reading, from the storage device, each block from the set of blocks:
• transferring the block over an interface with the host, and
• simultaneously performing error detection on the block;
• and
• if an error is detected in the block:
• performing error correction on the block to remove the error, and
• retransferring the block to the host after the error is removed from the block.
