Inside Solid State Drives (SSDs) (Springer Series in Advanced Microelectronics, 37)

The book was everything I needed to round out my SSD knowledge. Very useful, and the hard cover was in great condition. I hope to have this book until retirement.

Good to beginners on Flash NAND Memories & SSD productsDetailed diagrams & explanations of conceptsWell organized contents & chapters

Detailed book on SSD architecture suitable for new SSD hardware designers, firmware engineers who want to get up to speed quickly. The book offers a systematic overview starting with how HDD differ from SSDs, how NAND arrays operate, how SATA, SAS, PCIe SSDs differ, how supercaps differ from tantalum caps. Concise explanations of garbage collection, wear leveling including algorithms for implementing it, bad block management, ECC. Intuitive diagrams on how PCIe SSDs differ from SATA/SAS SSDs, overview of new standards like NVMe and SOP. Good overview of ONFI Toggle NAND vs traditional NAND. Unique features: Overview of hybrid SSDs, math behind BCH codes . Negatives: Overly focused on vendors like IDT, STEC. Each chapter has a different author some chapters like chapter 5 and 6 on NAND flash, parasitic capacitors dives deep into a level more suitable for SSD designers and covers new topics like 3D arrays. Omissions: Recent 1.8" form factor SAS SSDs, mention of A19nm NAND, real life performance numbers of commercially available SSDs.

The book can serve as a good reference about NAND flash itlsef, in any application, not only SSD.A lot of useful information about Error Correction Coding methods.The description of managing NAND flash memory feels academic and limited as most of the description is based on the articles and research papers. There is much less than expected reference to the real designs which can be found in published patents, only few quite old patents were referenced. (Of course, it is quite a personal statement, depends on what you are looking for).There is almost no description about FTL (Flash Translation Layer) design issues, the main thing making the difference in SSD's behavior.I could not find any information about the authors who wrote different sections of the book, only names. The three names on the cover are editors.

Eine Sammlung wissenschaftlicher Artikel, die man auch im Web leicht findet. Der Preis erscheint mir zu hoch. Sonst alles ok.
