Replace SSD drive with bigger capacity

I want to replace my existing SSD (C:\ drive) with new Samsung 840 EVO. What is the best way without re-installing Windows 7 Ultimate 64 bit. I would like seamless transition.

i found no performance differences with AHCI on or off
>>   I don't want to be in position where I have to re-install windows and software  <<  since the old disk is intact, you can always return , and re-image from it
2-i always keep system restore enabled - it helps often fixing problems
3-pagefile - use the recommended settings :
i use a setting  as minimum, or max 50% more
4- hibernation settings :  use this s:
you can delete the file then

You can use Acronis or a like tool to make an image of the SSD drive (I would make two) and then restore the image onto a larger drive. This should work. I have done this with Ghost at clients.

I recommend cloning the old one to the new one using Casper:

It works on W7, W8, and W8.1, all in both 32-bit and 64-bit editions.

I recently used it to clone a W7/64-bit system to a Samsung 840 EVO — worked perfectly, including retaining the Windows activation. It can clone to the same size drive or to a larger one or even to a smaller one, as long as there is enough space on the smaller one to house the used (non-free) space from the larger one. It's not free, but it's reasonably priced and worth every penny.

Another well-regarded (also non-free) product is Acronis:

I used it previously, but now prefer Casper.

If you're looking for something that is free, I've heard good things here at EE about these (some may be free only for non-commercial use — check the licensing terms for each):

But I haven't tried them as I do all of my cloning now with Casper. Here's a 5-minute EE video Micro Tutorial, Cloning a Hard Drive with Casper, showing how to do it. As a disclaimer, I want to emphasize that I have no affiliation with this company and no financial interest in it whatsoever. I am simply a happy user/customer. Regards, Joe

The Samsung 840 EVO comes with a cloning tool on a CD. I've used it w/o issues:
You can also download it here:

And for all who like opensource products. You can use clonezilla, which can be found here. But you need to be aware a little bit with linux device naming patters, else you might accidentially cause damage by choosing wrong disks.

one more thing about "Replace SSD drive with bigger capacity"
if you image the drive   -most softwares will image it to the same size - so you need to expand the drive to max size later with disk manager
the paragon software offers the resizing during the imaging process - so it's done automatically
Some important notes from Samsung_SSD_Data_Migration_User_Manual_ENG_v27:

- Source Disk (e.g. “C:” drive) must consist of at least 20% free space
-- However, if needed, it shows how to move files before cloning
- On systems with two(2) drives or more (e.g. “C:”, “D:”, and “E:” drives) with the operating system installed on the “C:” drive, only the first two drives will be cloned.

The easiest way to move your system and programs to bigger drive is Migrate OS to SSD:
With few clicks it will let you copy the system from old drive to new one. And it takes care of Windows boot and system partitions automatically even if they are installed on different drives.
Before actually putting data on the Samsung 840 EVO it's important to verify that the drive is containing the latest firmware which can be downloaded from this location (version is EXT0CB6Q)
If data is put onto the drive without this latest firmware version, the firmware update will have to rewrite all data.

I was able to install using Samsung's bundled software. The software counts drives from 1, whereas Disk Management counts from 0.
I posted this question as I read people were having issues with drive, yet it was one of the best selling ones.

Now having installed, I found instead of 100GB used space on previous SSD, this shows 82GB. What happened? All programs are running fine. Now I have questions below after running Samsung Magician. The firmware is up-to-date.
It warned me of absence of AHCI.
1. I found AHCI driver is not there in Device Manager.  The mother board has AHCI option, but it would require Windows repair (driver installation?) I am wondering how big of hit in performance will be there if SSD is not on AHCI? Or should I go with ahci enabled on motherboard and do Windows repair. M./B is about 4 years old. I don't want to be in position where I have to re-install windows and software. Any help?
2. System Restore is disabled, should I enable?
3. Pagefile and hiberfile.sys takes 8GB, do I need them? Samsung advises to set pagefile settings as 200MB to 2GB.
4. Since this is desktop, always on, I don't need hibernation mode. How do I get rid of hiberfile.sys?
Lastly I thank you all for various solutions you gave me. It increased my understanding of SSD drives and supported software.
powercfg /hibernate off

Open in new window

AHCI wont influence the performance. So you do not need to enable it. Move the OS to new drive and there configure the pagefile and hiberfil.
