How Much Photo Storage Do You Need for Photography?

One question that lands in my inbox a lot is “what size hard drive should I buy for photography?” While you may have to come to this post looking for an easy answer to address your photo storage needs, I will give you the answer that drives us all crazy but is absolutely applicable in this situation: It depends. The total photo storage size needed for your photography depends on a few variables, including the current size of your image library, the size of the image files from your camera, and the rate at which you create new images.

In addition, if you’re using Adobe Lightroom, you’ll want to include your Lightroom catalog as part of that calculation. The Lightroom catalog holds all the information about your photos. The catalog includes information such as your photos’ storage locations, each photo’s metadata, rating, keywords, and all editing information.

With that in mind, let’s talk about finding the appropriate drive size for your photo library, which is both the Lightroom catalog and all the image files.  Once you know the size needed, that makes the choice of whether that drive should be an external hard disk drive (HDD), external solid state drive (SDD), or even a redundant array of independent disks (RAID) solution much easier. Now, let’s figure out what drive size you need in three easy steps.

Step 1: Find the Total Size of Your Current Photo Library

If you have all your image files already saved in one location, check the total size of the parent folder. For example, I store all my image files on one drive with the main folder called “Image Library.” Under that main parent folder, I have subfolders for each year and then further subfolders within each year’s folder. 

There are big advantages to structure your image library with one parent folder holding all the subfolders. One advantage is that you can find your total photo storage size with two clicks. Right click on the main “Image Library” folder from within Lightroom or on the drive itself and then select “Get Info.” Then, under “Size,” it shows the total size of your current image library. If you’re on a PC, right click and select “Properties.” At the moment, I have a smidge over 5 TB of images on my drive.

Step 2: Find the Size of Your Lightroom Catalog

Next, find the size of your Lightroom catalog. From within Lightroom, select Catalog Settings from your top menu bar. Within the General tab, Lightroom will display the size of your catalog. To give some perspective, my Lightroom catalog is under 2 GB (giga not tera). That’s 177K images of various sizes taken throughout the years. In other words, the catalog doesn’t add that much to my storage needs compared to the size of my current image library.  Again, this is all unique to how a person edits and their workflow, but at least it gives a ballpark. 

Step 3: Assess Your Future Storage Needs

First, image file sizes from the same camera can vary wildly. They change depending on your camera file settings as well as your subject matter, ISO, and even lens choice. Most manufacturers publish typical file sizes in their manuals. And we all read our manuals front to back, right? For example, for the Canon EOS R5 with the default aspect ratio of 3:2, one image file size can range between 2 MB to 45 MB. This size changes as you select your image format (i.e., JPEG, HEIF, or RAW) and your quality (e.g., small, medium, fine, RAW, etc.). This is why it is best to look at your own image and folder sizes. Don’t let the internet help here (well, except for this article).

Since my folder structure is organized by years, I can see the total number of images taken each year. In addition, I can see if it is steady, increasing, or fluctuates. Just as I checked for all my photos in step 1, I can right click and gather the size information for each of my 2020, 2021, and 2022 parent folders. Each year is 1.3 TB, 1.1 TB, and 1.3 TB respectively. These folders contain my RAW images and my Photoshop files. Therefore, this gives me a better sense of my future annual space needs.

An easy way to use Lightroom or your photo library to learn how much photo storage you need for nature and landscape photography.

To wrap up, I know I currently have 5 TB total between image files and the Lightroom catalog. In addition, assuming the same camera and photographing rate, I require a little over 1 TB increase each year.  Now, all drives need to be replaced on a regular basis. Typically, manufacturers recommend every 3-5 years. So to plan for the next 5 years, I would need approximately an additional 5-6 TBs.

(5 TB currently library size) + (~6 TB planned for the next 5 years) = 11 TB size required

With that in mind, I would lean towards purchasing a 12 TB storage solution. That will give me enough space to cover that 3-5 year recap cycle. When I’m getting close to filling that space, it will be time to reassess and update my storage solution.

Shouldn’t I just buy the largest size external hard drive for photography?

Nope! If you are mostly doing photography (not video), then I wouldn’t necessarily take the plunge to a 32 TB drive right off the bat. First, large hard drives (that are fast) are pricey. Second, if I only have 5 TB of storage now, chances are I won’t fill that large of a drive for years with photographing stills along with the occasional video clips. By the time I fill or need that 32 TB of space, it will be time to refresh my photo storage solution anyway. If I had simply purchased the largest drive, then I would have spent money on storage I never used. With the price of larger SSD or RAID storage solutions, the savings from purchasing a smaller size drive could have been spent on a piece of camera gear instead.

Depending on the make, model, and storage environment, the average recap recommendation of an external hard drive or RAID drive is around 3-5 years.  This assumes there is no physical damage to the drive, either. The older the drive, the more likely something is going to fail. Every photographer needs to pick their own comfort level on how often they update their drives. As discussed in Let’s Get Organized in Lightroom, I have at least three levels of on-site redundancy plus a level of offsite redundancy for my entire image library (image files and Lr catalog). Therefore, personally, I’m comfortable stretching my recap cycle to every 5-7 years.

What is the common photo storage size range for most nature photographers?

An external drive in the 2 TB to 8 TB range is sufficient and a common range for most nature and landscape photographers. There is a real beauty when your image library is below 2 TB in terms of cost, size, and portability.

If you plan to travel with your external hard drive, the most common purchase is a solid state drive (SSD). SSDs are faster than hard disk drives (HDDs) and with fewer moving parts.  These are the preferred setup for portability.  HDDs are a common choice if you plan to set it up and leave it tethered to your computer at home.  Also, the read and write speeds of the drives need to be considered. Otherwise, you might impact and slow down your post processing experiences in Lightroom and/or Photoshop. As if that wasn’t enough, larger storage solutions eventually cross the threshold into redundant array of independent disks (RAID) setups. But diving into the pros and cons of SDD, HDD, and RAID is a whole other article better left for another day.

I know that is a lot of information on photo storage so I’m not sure if I should write “I’m sorry” or “you’re welcome.” But I hope it helps you figure out the right size drive to fit your needs. Happy Storing!
