If you know how to download a torrent file, you can speed up this process by putting bootstrap.dat (a previous copy of the block chain) in the Bitcoin Core data directory before starting the software.

Where is this directory for windows7, thanks.

AppData\Roaming\Bitcoin ?

AppData\Roaming\Bitcoin\chainstate ?

AppData\Roaming\Bitcoin\blocks ?

AppData\Roaming\Bitcoin\blocks\index ?

C:\Program Files\Bitcoin\daemon ?

I got it listed under favorites on win7x64, I do a lot of folder backups that are under AppData. Be a lot easier if I had the windows key on my kboard.

Btw, 19.2 gigs wtf? I recall when it was only like 2 gigs or maybe 4. I need a stronger processor to .7z the bitcoin folder. Takes an hour to .7z it all, two cores and two threads@full blast.

This feature is really cool though. Thumbs up to the devs. Only now if the program could read faster than 6MB/s = make the program scan much faster. >Edit:< I could be wrong it could be my hyperduo but I doubt it, even USB hdd's can read at 30 MB's sec. My hyperduo is capable of reading at 200 MB/s or so.

No expert here but that is probably sequential speed you are quoting on the SSD.  Bitcoin-qt performs a lot of seemingly random reads and writes so you are going to get speeds that are quite a bit less than your maximum potential.

And growing by a bit more than 200kb on average every 10 minutes.

That works out to be a bit more than 10.5 GB per year.

Under performance monitor "win7", you can see disk activity. Disk activity applys all read/writes "disk I/O" together then there is a box that shows "highest active time" Which either don't get maxed out. CPU gets at like 5-8%. So the program is limited I am guessing. Once I get my raid0 samsung 840 pros, I'll do more testing, but the bitcoin program seems very limited on my end atm. Using latest x64 bitcoin client.

Edit
This is importing the .dat file

Is this good or bad? I am guessing it's not bad but still a lot.

10.5 GB per year?

You can purchase a 4TB drive for less than $200.  At current blockchain growth that's enough to store the entire blockchain for the next 380 years.

Even at maximum possible growth rate with the current protocol (1 MB every 10 minutes on average), that's only 52.5 GB per year.  That means that 4 TB drive could store the entire blockchain for the next 76 years.

Those who want to be fully participating nodes will have to accept this cost (it averages out to less than $2.75 per year).  Anyone who is unwilling to accept it, has the option of running a light wallet such as Electrum or MultiBit.

Nice to know this info, Thanks.

Also, is that what mobile users do is use electrum or multibit?

How would a 4TB fit on mobile?

I'm not certain, but I think most mobile wallets are lightweight wallets built with bitcoinj (or something like it).

Ahh ok. I always wondered how mobile users devices actually handle the blockchain. Certain services. something like that. lol Smiley

I never imported the .dat before. It's just something I was no sure of :/ . I highly doubt anyone would wanna buy this account.

Theymos and mods know its me, they can easily check for my main IP I sign into once in a while. Smiley
