For the real geeks who like tearing into hardware

and are prone to using things like tablet PC's for

an EFB for in-flight charts, you may like this quick

write-up I just finished.



http://www.myrv10.com/N104CD/upgrades/20081214/index.html



I tore into my Motion LE1600 and put in a "homebrew"

SSD (Solid State Drive) so it works at all altitudes

now.  It really is something you'll want to have if

you go with an EFB, and it makes the EFB really

totally useable.  Voyager has been working really well

for me, so this was the final step in committing to

a paper-chart-free life.

Tim,



Great idea! Thanks for the writeup!

What does 233x translate to in Mb/sec?

Does it work as fast as with the old hard drive?

Did you have to disable write cache and other things for it to work right with Windows?



I have a Samsung Q1 Ultra, and run Anywhere Map on it. I'm thinking of SSD-ing it Tim style 



It's small and pretty bright. I had to write an on-screen  keyboard interface for it, because the original one is unusable in flight. Other than that it's a great system and cheaper than the Motion tablet. They sell them on ebay new for around $800.

Hi Lenny,



Supposedly, that RiData (the cheapest of the fast cards) that I

used is about 35Mb/s Read and 12Mb/s write.  I wouldn't call that

ultra fast, especially when you compare it to what you can put in

a desktop PC. But, in perspective it works real well.  The 4200RPM

1.8" drives are really slow, and when you take into consideration

the head access times and effects of file fragmentation, a regular

drive is pretty miserable itself.  A flash drive doesn't care about

fragmentation and never has to wait for heads to position.

A lot of people the SSD's "feel" faster, even though the sustained

read and write speeds aren't as fast.  Of course, if you actually

buy those $799 64GB SSD's, you get even more read/write speed, but

it's at a high cost.  The hard drive is usually the slowest part

of a laptop/tablet....so I always shop for 7200rpm drives for my

laptops.  I don't mind upgrades though, so as speeds climb,

and sizes grow, I'll swap the primary CF card in this for a faster

and larger one....when the price is right.



I didn't do anything for write-caching or any other special settings,

it just worked.  I haven't taken it on a flight yet, but everything

seems to work very similar to how it did before, so I'm happy.



Fun stuff to play with anyway.   I hear good things about

the Q1 ultra, but I like the larger tablet myself.  Another

builder has the Q1 and the same software as me and he wasn't

as happy with the screen size, so he's thinking of upgrading.

I think it all depends on the application you use as to how

happy you may be with one style or the other.  So many options

though, so there is a lot to choose from.

Which mount did you use or did you custom make one?

You mean physical mount??  For the tablet or the drive?

The drive is just using the stock shock mount.

I don't use a mount with the tablet. I prefer to be

able to pass it around.  My wife pulls up charts and

data for me all the time.  It's handy to be able to

move it. I would never want it hard mounted.
