Portable Device

SHANNYBUG · 03-13-2013, 04:46 PM

I have been using your application for yrs now and last month my laptop crashed and I lost over 2000 books. I now have a new laptop using Windows 8. I have learned my lesson and now use Calibre portable. It is very very slow and often I get (not responding) and have to wait even longer. Is there a portable device or size you recommend that is fast??

Did you mean to put this post in the Calibre forum? You put it into the "General Discussions" forum.

Didn't you back up your PC data?

Yep, this is the way to protect your data. If your data doesn't exist in three different places, it doesn't exist.

What kind of crash did you have that your ebook files couldn't be recovered? As long
as the HD or SSD is functional they should be retrievable.

And it does sound like this should be in the calibre forum. If the laptop is running the
regular Win 8, wouldn't you be using the regular calibre? I don't know about for RT,
and that would be for ARM based device, as I understand it.

Luck;

There are many USB thumbdrives that are fast and reliable, but they are not the cheap.

If you look online or in a store and the read/write speeds are not specified, then you can assume that the thumbdrive is too slow.

Here is a site that publish tests performed by owners of USB flash memories. There you can see that the speeds varies a lot. Usually read speed is OK, but to use for calibre you also need fast write speed.

I would suggest that you get a high end thumbdrive from one of the major brands. SanDisk, Lexar, Maxtor, Kingston, Corsair.

Anything slower than 20 MB/s read/write might be considered as too slow. And even that is quite a bit slower than the read/write speed you can expect from a normal harddrive in a new laptop. But MUCH faster than most cheap USB thumbdrives.

One of the fastest I have seen for sale is the Kingston Datatraveler Workspace 32 GB for USB 3. Kingston specifies both read and write speeds of 250 MB/s. That is fast! But it is not cheap.

It would be much cheaper, and easier to use, to keep the calibre library on the built in harddrive and get a few cheap USB thumbdrives to use only for backup. Then the speed doesn't matter as much, especially not if you backup using some sync utility that only has to transfer changes to the thumbdrive.
