I am the author of kcall.co.uk/ssd/index.html and I trust that the site is now back up and running without further 'sleeping' episodes. The reason for the interrupts was, as some have surmised, that the site was mentioned here and in other places and that caused a surge in hits that exceeded the host's usage limit. Whilst I am pleased that so many people have shown an interest in my efforts it does mean that I have had to move the site to a more generous host.
It is apparent from the first sentence and the website itself that this article is, or arises from, tha musings of shall we say an amateur. It's not professional because I'm not a professional. Whilst some of the comments in this thread are helpful, some are baffling. To the person who couldn't get past the header bacause Comic Sans offended him, the following 8058 words were in Century Gothic, which is perhaps not so offensive. I have however accepted the comments on readability and changed the header and all the rest of the text to Calibri, made the font larger, and changed the line spacing to web standards. I hope it is now more soothing and readable. As for the claim that the text is 'spoiled by having dozens of typos and spelling mistakes' I'm not sure what he is reading (or smoking). Apart from the removal of one stray colon, the current text is entirely unchanged - it is the same file. I don't claim to be perfect and I'm sure that in such a large essay there are some typos and other errors, but to say that there are dozens is patently untrue. Just let me know where they are and I will happily correct them.
Apart from all that, I am surprised that there are so few comments about the veracity or otherwise of the contents. I had great difficulty in finding material that was up to date and actuially delved into the technicalities of SSDs, without baffling me - as much did.
I shall end by thanking those who found the article interesting and I hope that some of it at least has been of some help.
