Backblaze, Inc. announced a new innovation on data upload technology it calls "shard stash," which delivers significantly improved upload speeds with small file uploads up to 30% faster than AWS S3. The increased speeds benefit all Backblaze B2 Cloud Storage customers, especially those who rely on small file upload (1MB or less) which are common in many use cases including backup and archive workflows. Many data protection software providers split data into smaller, fixed-size blocks for upload to cloud storage, meaning users can expect to see significantly faster upload speeds for smaller files without any change to durability, availability, or pricing.

Specific benefits of the performance upgrades include: Secures data in offsite backup faster; Frees up time for IT administrators to work on other projects; Decreases congestion on network bandwidth. The "shard stash" performance improvements combine economy and performance by leveraging the speed of solid state drives (SSD) to quickly ingest short-term copies of new data (the shard stash) while hard disk drive (HDD)est copies it for long-term storage. The new technology has been fully rolled out to Backblaze's global data regions.

These are the latest in a series of upgrades announced by the company, with additional B2 Cloud Storage download performance enhancements planned over the coming months. These speed improvement claims were validated through a rigorous testing methodology which is explained in detail along with more information about the performance improvements and implementation on the company's blog.
