SSD drive installing
Now the prices of SSD are dropping f.i. SAMSUNG EVO 500GB 230€
My HD had "only" 20GB free space plus my external backup crashed did me decide to move to SSD.
I had only once used a SSD until now in a Panel PC 64GB
performance index went from 5.9 to 6.5 the video is now the slowest part
drive went from 5.9 to 7.7
I followed the SAMSUNG installation procedure that came with the drive.
I did not have the special SAMSUNG SATA-USB cable.
but Connected the SSD over USB to the SATA interface of my defective ADAT 1TB USB drive.
The disc clone operation takes over 3 hours for 285GB with a transfer speed 20MB/sec using the USB3 port to the Sata USB interface this one was not USB3 speed I think.
Samsung migration does not copy the Windows memory image files they are not needed. That saves unnecessary 10GB date transfer.The recycle bin was not skipped. I my case 13.5 GB...
Once installed the SAMSUNG software needed an upgrade to the latest version.
First time the transfer interrupted after 2 hours then I started again and left it running in the night.
The drive did not show up in Explorer also not in EASEUS drive manager..
Only the Samsung migration program found the SSD drive.
It was not so clear to me whether Samsung Data Migration program would make the SSD a cloned bootable W7 drive
I could not believe it was that simple and it worked! it took some time to transfer the clone possible with an original USB SATA interface that cold be faster.
Until now I thought that to make a copy of the Windows drive/partition the O.S. has to be shut down because some files can not be copied when in use.
More confusion comes because Samsung migration tool also notifies that files in use might not be copied correct.
When Googeling on this subject the advised procedure was to use Macrium reflect freeware disk backup / imaging program it looks nice. Then with this program make a LINUX rescue CD and a disk image saved to an External USB drive with sufficient free space of course .
The PC must boot with the recovery CD and then the image should be copied to the installed SSD
This is a bit confusing. Why using a relative complex procedure if the Samsung migration program could do it direct?
Next morning I found the cloning was finished successful..
I replaced the HD with the new SSD used a soft rubber strip to fix it in its place.
The original HD is thicker and heavier too.
The drive was booting normal
After boot SAMSUNG magician message showed up
This is a managing tool for the SSD Possible It can improve the performance.
Not optimised the sequential read test was 279MB/s it can be to 540MB/s
the sequential write 248MB/s relative low ?
I do not know what value is good for my System Lenovo W510 quad 1.73GHz 12GB ram
a better look
Magician noted that my Laptop did not support SATA3 mode 6Gb/s but SATA2 3Gb/s
meaning this laptop can reach 3000000 b/s or 300Mbyte/s "only"
But I could check the "rapid mode" and then the performance test shows
630 544 MB/s
anyway much faster then HD 100MB/s but if could have been > 1000MB/s with SAT3...
I switched back to the original 57Wh battery-pack the 94Wh pack is nice but heavy
I use to carry Laptop in a backpack al together 10kg now 9kg ..
I am now working with my new SSD 500GB.
At first the boot of Windows was not very much faster .
Possible the OS has to be aligned .. that was also mentioned when googling
This was new for me When installing Windows new from the CD Windows is installed Aligned.
Meaning the disk partitioning is aligned with Windows system files that should make it work faster.
To check if your Windows is aligned use MSinfo32 then the drive information shows
start offset of partition devide this by 4096 it should result in an integer value..
But then what to do if in my case the result is a fracture value?
And an other thing why should that be important for an SSD that has no moving parts to address all sectors? no further explanations found yet to this subject.
A good tool to show what is consuming your drive space is a program called
Spacesniffer V 126.96.36.199
Shows a Brilliant graphic map of the HD or SSD
BTW Magician does not let me paste screendumps to Picasa to show here
if anyone still reads or finds this blog interesting.

Oh yes this morning got up early for 80m TX6G but no sign of them. This is about the last day to catch them the expedition ends April 1
I found TX6G phone 17m 18135kHz Spaghetti mode again!
5kHz small uplink overloaded with EU callers. They where 56 with me only South Europeans were picked up EA1 I6 CT etc from a giant pile of callers every 1 or 2 minutes... arrrrgg
This type of operation does exclude NW-Europe callers unless running extreme hardware.
Where were the real operators? resting or cycling?
And that was the best thing for me to do also..
Much later in evening when back home TX6G was now 18091 CW but very weak just could copy
still huge pile.
But this time I was heard in the pile now 7 bands CW 80 missing.
Also ZL7AAA was still on 18160 phone much stronger than TX6G and still a big pile.
but even here I was copied when the ON station was told to stop calling, my call was copied correct
woow Chatham our ultimate DX 19000km almost
Strange behaviour when you hear ZL7AAA repeatedly clearly calling for PA0? PA0OP ? but still you call over the pending contact and make a simple quick QSO difficult and unneeded slow.
