Now that is one for me....probably be silly money though....



Still the price will drop....

Get two, one for boot one for /var....

For / and /var 4 gig flash is probably enough in fact I would split one
in two, 2 gig for / and 2 gig for /tmp or 1gig for / and 3 gig for /tmp
if I had lots of users......

Only if you also have /usr in a separate partition too. I tend to prefer 8Gb
for /, 4Gb for /usr and 10Gb for /usr/portage (running Gentoo) and whatever
I can chuck at /home.

Why would it be silly money? 1Gb flash drives are under $100 already?

Performance and number of writes....my undertsnading is the stuff that
goes into cameras has a quite limited amount of writes, which is good
enough for cameras but not good enough for an OS partition, especially
logging....so existing cards might be OK for static partitons like /usr....

FWIW Windows Vista ReadyBoost & ReadyDrive
http://www.microsoft.com/whdc/system...celerator.mspx has an
algorithm that chunks data up as its written to the flash media to
ensure that the device doesn't wear out

We are smart about how and when we do our writes to the device. Our
research shows that we will get at least 10+ years out of flash devices
that we support.

Ah ok.....thought maybe this was substantially better stuff, rather than
a work around, however effective.....

and what about fragmentation? and its in he background cleanups, turned
off for these drives?

10 years+ is a decent safety margin.....given the rate of change after
or 3 I'd expect the wearing out to be no longer an issue.....

Quite why you could not do this in hardware on the disk itself I dont
know....

Depends on the distro i think. I pretty much alwys do /usr as seperate
unless Im cramped for disk space then I do / and /usr the same.....say
on a 9 or 18 gig drive....

RH wants around 6gig for /usr with a full install so i tend to set 8 gig
with 1 or 2 gig for / which seems enough....I notice debian has
different requirements so / tends to be made bigger and /usr smaller....

Depending on your use, I would suggest you seperate /tmp off as well as
/var/log as these are loging partitions....I have seen a 14 gig /var
fill overnight...then redhat logs to /tmp so that gets filled...once
full on /var you cannot remotely login....depends on if that is an issue
for you or not.

Not a problem the unique write gathering algorithm optimizes
performance and wear patterns and doesn't suffer from frag

correct

Some of the projected device wear test we have done put it out to 1823
years (!) depending on device size, variant, and usage patterns

Yes I think you're likely to have lost your device or the storage space
will be irrelevant by then

We do actually do both.

ReadyDrive is the Hybrid Hard Drive where Nonvolatile cache (NV Cache)
is added to the hard disk drive which allows data to be read and
written while platter is spun down
Also improves battery life and startup speed as data in cache persisted
when powered down. Other benefits are Performance (Faster boot, faster
hibernate/resume) Reliability (vibration and impact doesn't affect NV)
and reduced noise

and then ReadyBoost if for Expanded Memory Devices with works with
External USB keys, SD cards, Compact Flash, internal PCIe cards

Its all about avoiding the disk bottleneck, the slowest thing in a PC,
the thing that really hasn't changed much in the last 10 years -
ReadyDrive/ReadyBoost allows fast reads to satisfy page faults when
page is not in main memory. These are up to 10x faster than random HDD
reads because the latency for USB Flash Drive ~0.8 mSec

This is a cool technology that improves performance and reduces power
usage for Windows Vista Mobile PCs

And "they" claim MSFT doesn't innovate...
