No harm in compiling on a hard-drive, via NFs or otherwise. I believe |
10 |
read speed of SSDs is fast, writes are slow. |

However, I am sceptical of wear claims, at least of you're using ½- |
13 |
decent flash memory (and SanDisk & Kingston are cheap these days, at |
14 |
least in "modest" but usable sizes like 4gig). |

I have read many people talk about wear of flash memory to be a |
17 |
problem, but I don't think from anyone who's actually HAD a problem |
18 |
with it. I have read of many people using it happily for root |
19 |
filesystems over periods of years. |

I concede that syncing the portage tree & the compilation of emerging |
22 |
packages results in an above-average number of writes, but I have this |
23 |
notion that the wear / limited writes problems have been largely |
24 |
overcome with modern flash memory (c.f. "write levelling"). |
25 |
Furthermore I have heard figures bandied about in the order of |
26 |
100,000s per block and such as "you'd need to write to the flash card |
27 |
constantly for years" in order to kill it. |

|

I would really love to hear empirical evidence either way on this |
30 |
matter, but I don't think the OP needs to be too cautious of wear. (Of |
31 |
course this advice is worth what he paid for it, and warrantied to |
32 |
that value). |
