Amazon EBS Cold HDD Volumes

Lowest cost HDD volumes for colder storage offering up to 250 MB/s of throughput per volume
Get Started with sc1 volumes

Cold HDD (sc1) volumes provide low-cost magnetic storage that defines performance in terms of throughput rather than IOPS. With a lower throughput limit than Throughput Optimized HDD (st1) volumes, sc1 volumes are a good fit for large, sequential cold-data workloads. If you require infrequent access to your data and are looking to save costs, sc1 provides inexpensive block storage. Bootable sc1 volumes are not supported.

Benefits

Cold HDD (sc1) volumes offer the lowest cost of block storage in AWS. They are ideal for workloads characterized by large (1 MB) block sizes which need less than 80 MB/s of throughput per TB or 250 MB/s per volume with bursting, while generally needing under 12 MB/s per TB of throughput for their baseline needs.
Cold HDD (sc1) volumes are backed by hard disk drives (HDDs) and are ideal for infrequently accessed, throughput-intensive workloads with large datasets and large I/O sizes, such as Hadoop clusters, Windows File Server, log processing and big data workloads with large data sets.
Cold HDD volumes deliver baseline throughput of 12 MB/s per TB and up to 80 MB/s per TB or 250 MB/s per volume while bursting, making these volumes ideal for IO intensive workloads with relatively low baseline throughput requirements.
