The Buzz and Fuzz on SSD in Hadoop
Hadoopsphere's analysis of SSD adoption in Hadoop clusters — the trade-off between SSD's dramatically faster random I/O and its higher cost per GB compared to spinning disk. An early look at how flash storage would eventually reshape big data infrastructure.
Is There Room for SSDs in the Hadoop Framework?
StorageTuning blog's technical assessment of where SSDs fit in Hadoop's storage hierarchy — evaluating specific bottlenecks (NameNode metadata, shuffle I/O, random reads) where flash storage provides measurable gains over spinning disk.
Anatomy of a Solid-State Drive
ACM Queue deep dive into SSD internals — NAND flash cells, wear leveling, garbage collection, and how the FTL (Flash Translation Layer) hides the physical complexity from software. Essential for understanding why SSDs behave differently from spinning disks.
Benchmarking High Performance I/O with SSD for Cassandra on AWS
Netflix's 2012 benchmark of SSD-backed Cassandra on AWS EC2 — showing 3-4x latency improvements over spinning disk for their use case. An early real-world data point on SSD economics in cloud distributed databases.
