Backend database applications relay on good storage systems for performance, durability and low latency. SSDs have been a great invention that changed the storage game compared to mechanical drives. However, SSDs came with their own sets of problems which can cause database reads and writes to plummet after a while. This episode discusses the current limitations of SSDs include garbage collection, wear leveling, over provisioning and how zoned namespaces “may” fix this. 0:00 Intro 1:40 Block 4:00 Logical Block Addressing 6:00 Flash Translation Layer 6:50 DRAM 8:50 Erase unit 11:11 Namespace 12:00 Summary 13:40 Garbage collection 16:49 Over provisioning 18:00 Write amplification 21:28 Wear leveling 23:14 Zoned Namespaces Resources https://www.guru3d.com/news-story/new-malware-bypasses-security-measures-by-using-ssd-over-provisioning.html https://www.snia.org/educational-library/zoned-namespaces-zns-ssds-disrupting-storage-industry-2020 https://www.youtube.com/watch?v=cbX3P56Jp0o&feature=emb_title Fundamentals of Database Engineering udemy course (link redirects to udemy with coupon) https://database.husseinnasser.com Introduction to NGINX (link redirects to udemy with coupon) https://nginx.husseinnasser.com Python on the Backend (link redirects to udemy with coupon) https://nginx.husseinnasser.com Become a Member on YouTube https://www.youtube.com/channel/UC_ML5xP23TOWKUcc-oAE_Eg/join 🔥 Members Only Content https://www.youtube.com/playlist?list=UUMO_ML5xP23TOWKUcc-oAE_Eg 🏭 Backend Engineering Videos in Order https://backend.husseinnasser.com 💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2 🎙️Listen to the Backend Engineering Podcast https://husseinnasser.com/podcast Gears and tools used on the Channel (affiliates) 🖼️ Slides and Thumbnail Design Canva https://partner.canva.com/c/2766475/647168/10068 Stay Awesome, Hussein
