Amazon is currently discounting several SUIDEK external CD/DVD drives that double as multi-port hubs and storage docks. Models range from $28.79 to $39.99 and vary in extras, including a SATA 2.5-inch drive dock, an M.2 NVMe SSD dock, SD/TF card readers, and USB-A/USB-C hub ports. All models read and write CD and DVD media at up to 24X and 8X speeds respectively and support a wide range of Windows, Linux, and macOS versions.

Solid-state drives now come in two main interface types: SATA, which tops out near 600 MB/s in theory and 500-560 MB/s in real-world use, and NVMe, which runs over PCIe and can hit roughly 3,500 MB/s on older Gen3 drives up to nearly 15,000 MB/s on newer Gen5 models. Both technologies store data on flash memory and vastly outperform mechanical hard drives, but they differ sharply in how they connect to and communicate with a computer.

A PostgreSQL performance researcher shared follow-up findings on the database's random_page_cost setting, which governs how the query planner estimates the cost of random versus sequential disk reads. New benchmark data from older rotational SATA drives showed an estimated cost around 125, far higher than the long-standing default of 4.0, while SSD-based tests land closer to that default only by coincidence.
