Nand flash SSD and NVM server storage I/O memory conversations

aka and

Now and then somebody asks me if I’m familiar with flash or nand flash Solid State Devices (SSD) along with other non-volatile memory (NVM) technologies and trends.

Having been involved with various types of SSD technology, products and solutions since the late 80s initially as a customer in IT (including as a lunch customer for DEC’s ESE20 SSD’s), then later as a vendor selling SSD solutions, as well as an analyst and advisory consultant cover the technologies, I tell the person asking, well, yes, of course.

That gave me the idea as well as to help me keep track of some of the content and make it easy to find by putting it here in this post (which will be updated now and then).

Thus this is a collection of articles, tips, posts, presentations, blog posts and other content on SSD including nand flash drives, PCIe cards, DIMMs, NVM Express (NVMe), hybrid and other storage solutions along with related themes.

Also if you can’t find it here, you can always do a Google search like this or this to find some more material (some of which is on this page).


Flash SSD Articles, posts and presentations

The following are some of my tips, articles, blog posts, presentations and other content on SSD. Keep in mind that the question should not be if SSD are in your future, rather when, where, with what, from whom and how much. Also keep in mind that a bit of SSD as storage or cache in the right place can go a long way, while a lot of SSD will give you a benefit however also cost a lot of cash.
