My knowledge of storage Hard Drives and SSD is getting out of date and I would like to know what tools are available to read more extensive SMART and other data from modern drives than just "SMART Verified".
My knowledge is about summed up from reading Louis Gerbarg's article on from write() down to the flash chips and occasional summaries of the state of the art SSD from http://www.anandtech.com
As drive controllers get smarter, it seems the old "wisdom" about zeroing a drive or what happens when a block is "bad" are less applicable. I'd love any links to great technical write ups (newer than 1 ) on modern storage technology as well as programs that can access engineering data on the SATA bus and other ways to tap into the storage subsystem short of hardware dissassembly.
Bonus points for tools and information on failure modes and engineering that allows these devices to work while degraded and ensure data is marked as corrupt when detected. There are commercial products that parse this data for HDD like Drive Genius but I'm unaware of any tools that expose data from SSD like wear leveling or predict flash failure due to over use based on current or historic write rates.
Answer
There are very many disk tools for ordinary hard disks. See this thread for a long list :
Best Free Hard Drive Health Monitoring & Diagnostic Programs.
Some of them may also do SSD, but the results are not too sure to be valid.
Below are some such products for SSD :
In all cases, it is always safer to use the tools created by the manufacturer of the SSD.
