Partitioning Advice - Single SSD

Win 11 Pro v.25H2

My Laptop now has a 1TB SSD as a replacement for a 500GB SSD. I'm looking for advice - pros and cons - of the best way to Partition the new drive. At the moment, it has a single C drive partition. Should I leave it this way, or add another partition?

It's personal preference to some degree. I'd leave it as a single C unless you have a strong reason to do otherwise. Do you have any external drives at all, or any backup procedure?

I have a 1TB size SSD in both my System One and System Two. For me, folders make a lot more sense than partitioning.

By default (clean install) all drives have 4 default partitions.



The default partition layout for UEFI-based PCs is: a system partition, an MSR, a Windows partition, and a recovery tools partition.





A GPT drive may have up to 128 partitions.




It's personal preference for the number and layout of additional partitions.

^^ This is my preference as well. I always find that if I partition a drive into additional pieces, I always end up regretting the size that I selected later. I end up with something that is either too large and robs space from the other partition, or it is too small and I start regretting that I didn't make it larger. A single partition eliminates any guesswork or need to make changes later because plans changed.

EDIT: I should add that I keep fiddling with this. I have experimented with different partition schemes, but in the end always go back to one big Windows partition. If I really need more space, I add another drive, or replace it with a larger one.

I've upgraded a few of my laptops from their original 500GB drives to 1TB SSDs.....

Yes, it's an entirely personal choice. I use Macrium Reflect to make system images of my PCs. After my SSD upgrades I like to use some of the extra space to add a D: Data partition. I can then store my Reflect system images on that partition. You cannot save an image to any of the partitions being backed up, so you either need an external drive to back up to, or a partition that's not part of the image. Having an extra partition means I don't have to find an external drive whenever I make an image.

Of course, saving an image to the same drive as the system it's a image of risks loosing both the system and its image should the drive fail. So I'll copy the image to an external drive later. It's just a lot more convenient to make the image on a local partition first. Faster too, writing to an internal drive beats usb speeds to an external drive.

The ideal would be to have two separate internal drives, but not many laptops support fitting a 2nd internal drive.

Up to you and your needs.
On my 500GB I removed the Recovery partition and the 16MB MSR partition and did this...

Personally, I leave about 130GB for my C drive [Windows & applications] and put the rest into a D drive for my own files [e.g. audio, video, MSOffice documents, ...].
This way I can make fairly small system images of my C drive quite quickly and I can restore them quickly if needs be.
I make simple file copy backups of the contents of my D drive.

I have 2TB drives in my two office machines and my laptop. I have partitioned them into multiple logical drives. I've done this since the Windows XT days, and it works well for me.

I have a weekly Windows O/S backups.
I have a separate daily backup for my data drive.
I have periodic backups, mostly bi-weekly, for my archive and multimedia drives.

If my Windows drive gets corrupted and needs to be restored/rebuilt, my data is not affected.
Conversely, if my data is compromised, I have daily backups that goes back two months day by day. I also have longer term data backup that is done bi-weekly that goes back for two years.

On a larger format drive, I do like to create a C drive of about 512GB for the OS, and the remainder as a second partition for data and games. This allows me to easily make an image of my C drive and restore an image of my C drive without having to also include games and data.

I support partitioning for the many reasons well stated above. The C: should be large enough for the OS, all the installed programs, plus free space of 50-100%. This allow room for additional programs to be install, the inevitable growth of the OS, and working room for OS updates.

To keep it simple, I use the default 4 that @zbook mentioned in post #4

So true. Externals with backups.

Bear in mind that you can effectively accomplish the same thing with a single partition. I'm not trying to push anyone into this method - your choice is a personal one. I am merely pointing out that even with a single large partition, there are easy methods to data organization and backups.

Here is an example of how I do this on one of my Mini PCs:

This Mini PC has a single 1TB SSD with one big C: partition. I use Macrium reflect to make a disk image BUT I exclude all my user data folders and my Virtual Machines. So, I now have the basic disk image minus the huge amounts of data files so I can restore that rapidly in the event of a failure because that backup is fairly small in size.

Next, I perform a second backup, this time it is not a disk image backup, but a files and folders backup that backs up the data folders.

I schedule the main Disk image backup for 6:00 AM every day and the data backup at 6:01 AM. That causes the data backup to kick off immediately after the disk image backup.

This has a few advantages for me: First, there is rapid OS recovery because I only need to restore the small OS image to get up and running. Then I can restore the data in the background while Windows is up and running.

Another advantage is that I can set different retention rules for the two backups. For example, for the main OS image I don't need to hold on to previous backups for very long. For my data backups, I maintain all daily backups for a period of 3 months and weekly backups out to 6 months.

Note that I stated that I use Macrium Reflect, but you can use other backup programs like the excellent "Drive Snapshot" to accomplish the same thing.

You can do it that way, but prepping my backup is much easier, I just point to the logical drive and perform a backup. When the folder structure changes, I don't have to adjust anything.

Whatever blows your hair back.

True, it may require a little planning. But I emphasize LITTLE. For example,

I place all my data under a folder called "C:\My Data".

That is my entire planning.

If I need to change the structure of folders or data, I do that WITHIN the C:\My Data folder, as a result I never ever have to change the parameters of my backups.

My problem is, I don't want to backup all the non-Windows stuff on my daily data backup run! I have a huge multi-media library that I only backup by weekly, the same for my archives, no reason to do daily backups on those.

In any case, my method works just fine for me. Also, if something happens to the disk structure of the Windows drive, I can hammer that back into submission without worrying about what happens to my data.

Why do you think I can't restore just the Windows partition, it's totally separate from my data!

First, I realize that you can restore your data separately. I was noting that this is a way to accomplish that even with one big partition. In other words, these are advantages vs. doing one large backup of everything rather than dividing it into two backups.

Also, I acknowledged right at the outset that I'm not trying to convince anyone to change their method. Merely pointing out that for those who prefer to go single partition, there are absolutely no negatives to making that choice if you plan correctly. In fact, it avoids the regret that come later if you sized your partitions non-optimally or your plans change at a later date.

Seems there are negatives with that strategy. If/when you need to restore the System then you have no choice but also need to restore the Data as it would be wiped by the System restore. This Data restore would have to a full, not delta restore. If the System restore is planned, not a hard crash, then you can do a backup of the Data so that it is current.

In the separate partition model, only the System restore would be performed.
