Mac OS X Earlier this week, Apple released the first developer preview of Mac OS X 10.7 Lion. At the same time, Apple listed a number of new features we hadn't yet heard about, which are quite interesting. There are two themes: bringing iOS to Mac OS X, and adding features other operating systems have had for ages - except in such a way that you can actually use them. Update: Fixed that scrolling thing. It's the other way around of course.

I wonder if saving files every hour isn't a bit of overkill, though. Especially taking into account the fact that SSD lives are measured in writes.


Word autosaves every 10 minutes. However, the extra versions Apple are proposing aren't likely to cause a whole lot of extra wear on SSDs - most writes aren't simple user data anymore. A single 100Mb update balances 1,000 hours of editing a 100Kb word document, for example.

Depends on what SSD manufacturers call a "write". If touching a block (even slightly) is a write, then a 100MB update could not be so far away from a 100kB word document, depending on block size.

In principle this is true, although it's nowhere near this extreme. NTFS needs to write to six places to create a new file - assuming a 256Kb block size, that's 1.5Mb. Note (for fair comparison) that a 100Mb (to download) update will expand into a much larger 300-400Mb set of writes to multiple files. Assuming the average file size being replaced is 2Mb, we'd have (400Mb / 2Mb) * (2Mb + 1.25Mb), or 650Mb of block writes. So the single 100Mb (to download) update is still 433 word saves.
