[Mut@nt] HD51 Disk initialisation order when waking up from Deep Standby

[ccs]

Once it has been read it will be cached in memory.

Won't that happen with an HD as well, or is there a re-read of the directory, say, to check for any changes?

I read somewhere that NAND chips in USB do suffer from wear even just reading as it's approximately equivalent to 10 write cycles = 1 read cycle. This affects some type of NAND chips more than others.

Ultimately, as I said, it depends on whether someone has timeshift enabled because if they do then they're already using HDD so why put wear/tear on USB as well as HDD when no need. I've used HDD for years without an issue that includes timeshift and recording.

If not using timeshift, then yes there is an advantage to using USB (speed of displaying picons due to no spin-up time).

... but on modern chips you are looking at cycles in the millions before hitting this issue..... whereas with HDD (although they are in general better ... you have latency, seek issues and wear through head/media issues).
So for recording and timeshift - HDD is fine.... but for events like Picons , settings backup, image backups ... usb is perhaps preferable, especially as its moveable.
Like everything its a case of getting the best out of the technology

USB suffers from all of these issues (except seek).

This is where we disagree. You're effectively stating that even when using timeshift, it's still better to use a separate USB for storing picons?

What is advantage of this because if using timeshift, you already have HDD upto correct spin speed anyhow and working so as well wear/tear on HDD, this also means then extra wear/tear of USB as well as HDD.

Once it has been read it will be cached in memory.

As mentioned by @ccs, if it's cached then surely that equally applies to HDD as well if cached by box in memory and therefore the WoS guidance that USB is recommended for picons even if using HDD (due to timeshift), has little bearing other than add to wear/tear of USB as well as HDD.

I would suggest this post is closed before it goes even further off topic

Well, yes it will - but the issue with using the HDD is spin-up time. As you say, if you're using timeshift you'll have it permanently on (using power) anyway.
