Except for a recovery image, I can see no good reason for partitioning any drive, much less an ssd
Those claiming it’s easier to backup, neglect the fact, with modern files systems, you can easily create “virtual partitions”_ (a term I personally made up) just by making a file and putting all the data you think you need backed up into that file.
These files can have sub-files and will for most practical purposes, do the same thing as a partition.
I suppose a case could be made, if your os is on a separate partition, you can image that to save operating system settings, but there’s no practical reason you wouldn’t image your files along with the system, not to forget, if the drive fails that partition usually fails too.
Your backup has to be on a separate hard drive if you want actual redundancy.
Image your operating system including files to a separate hardrive. this is the best backup, especially if you do it on a schedule, deleting older images along the way.
If you’re replacing the entire computer, not just the hard drive, that image isn’t usually going to boot on new hardware.
The 5 preceding answers are correct, but perhaps lack appropriate emphasis:
- If you are neither making backups nor running multiple OS instances, multiple partitions effectively have no benefit
- Recovery provided by Microsoft blows away installed apps (and license keys)
- Proper system backups (stored offline) (using e.g. AOMEI Backupper) will preserve the OS with your configuration and apps, saving much time when restoring after Win 10 corruption.
- Backup of OS and apps system partition from SSD to local eSATA or USB 3.1 external drive takes only a few minutes, and many will fit on an older and otherwise useless drive.
- Powering on an external drive and firing off a system backup becomes almost effortless (and more likely done).
Of course, offline data backups should also occasionally be updated to mitigate against internal drive failure, ransomware or horrible fat finger errors.

Discover the value you can get from the data created by your virtual and physical infrastructure.
The truth is you should never have any data that you can not afford to lose stored in only one location.
Put your data on C: if you want to but back it up somewhere else as well.
Sooner or later something will happen that will stop you from being able to restore the drive.
I’ve seen Windows reset options fail to work.
And in my own case my computer was hit by lightning, I didn’t lose anything because I had virtually all of my data backed up on external hard drives.
I had to put in a new drives, reinstall Windows and all my software but my data was safe and only needed to be copied back to my computer.
If you’re running Windows from a SSD then you should just install conventional hard drive and put all your data backups on it.
That includes a system image file that will restore your entire C drive including the boot sector in one operation.
None. There are no benefits.
A lot of “IT experts” will warn you of various theoretical scenarios like “but what if you want to re-format and start with a fresh copy of Windows!”. This was true in the 1990s and 2000s, but has not been true been since at least Windows 8.
“Reset my PC” in Windows 10 provides two different approaches to getting a fresh copy of Windows:
They both work exactly as advertised, and in the case of “Keep my files”, you will find a file on your desktop afterwards that lists all the software that was uninstalled.
Don’t be talked into an over-complicated setup that reduces your SSD’s lifespan, gives you less disk space for your files, adds complexity to installing software, and introduces disk space challenges when installing newer versions of Windows.
I use 3 partitions. One for the operating system and applications, one for data files and one for media files.
I can easily backup my data and media partitions to a USB flash drive, micro SD memory card or cloud storage.
If I am filling up my SSD, I can remove the media partition and store the media files on a USB flash drive. Then I can expand the size of the operating system or data file partition.
If you are using a hard disk drive, each partition can be defragmented and optimized separately for best performance.
When running an antivirus or antimalware, I can scan any partition separately.
I can clone the operating system partition without including the data and media files.

Many years ago the performance of large HDDs (in those days 100MB was a big drive) was slow. Under FAT32 it took a long time to find the right file on the drive. Partitioning the drive made it easier and quicker, reduced the seek time and the wear on the drive mechanism.
Today I still partition HDDs simply because I see no sense in having small size files such as documents in the same partition as large media files.
I dont partition SSD’s (cant afford one big enough) but I do use an SSD for my OS installation – so my standard config is
SSD C: Windows
HDD partitioned as D: Documents, E: Media, backups etc.
Otherwise, I dont see any benefit to partitioning an SSD.
The original reason to do this was back when large SSDs were prohibitively expensive. 64 GB would run you $100+. Put Windows and commonly used programs on the fast storage and everything else on the slower drive. It was the most cost effective way to set it up and noticeably improved performance. Fortunately, it’s not as important anymore as 512 GB drives are reasonably priced.
However, it still has the side benefit of keeping OS/Program data and everything else separate. Then if you ever have to reinstall your OS, you technically don’t have to back up your data.
Many would say to keep the data files and the system/program files separate, but that is not a good strategy on an SSD. SSDs have the advantage of speed, but two major flaws: a more limited read/write number, and a tendency to lose data faster than Hard Disks.
Ideally you’d want your windows installation on your SSD, and your files on a separate hard disk. The second hard disk should be partitioned to facilitate backup of files, keeping programs and files separate.
Only very heavy applications should be installed on the SSD to prolong its lifespan.

There are no benefits unless… Unless you have a 3rd partition with a Linux ditro and you want to share data between the to OSes. Since Windows 10 (nor any other Windows just-out-of-the-box) can’t even read Extended partitions (like ext4) and Linux’s ntfs-3g is for from perfect (and you know safety first).
But only having one OS, there’s no benefit. If you can’t boot into Windows, you can still access it’s Recovery Environment and you can ‘reinstall’ Windows from there -without touching your files.

As far as I see, there is no apparent benefit. I could point one if I have to say one. It’s more convenient with only two partitions on an SSD. Just ensure to align partition.
