Last Updated: 25 July 2025

When choosing which size of flash drives to give to your clients, we always advise them to put some thought into it. It's because we need to strike the perfect balance between functionality, budget, and purpose.

In this post, we’ll break down the different size capacities of flash drives you may choose for your giveaways and help you determine which one best suits your needs.

The Basics: What Do USB Drive Sizes Mean?

USB drives come in a range of sizes, usually measured in gigabytes (GB), and can vary from 4GB to 128GB (and beyond). The size you choose is all about the type of content you want to give your clients or event attendees and how you want them to engage with it.

While it’s easy to assume all USB drives are pretty much the same, choosing the right size is about matching it with your business goals. Let’s break down the most common USB flash drive sizes and explore how they can be effectively utilised in your marketing efforts.

4GB – 8GB Flash Drives

The go-to size for Australian clients is typically around 4 GB to 8 GB custom plastic USB drives. These smaller sizes are ideal for businesses that need to share basic information, such as PDF brochures, business presentations, or simple product guides.

Who is this size good for?

• Event organisers: If you’re running a conference or trade show, these drives work great for distributing event schedules or basic product information.

• Small businesses: If you’re just starting and need an affordable giveaway, this is a budget-friendly option.

• Large-scale giveaways: Need a promo item for hundreds or even thousands of people? These smaller drives keep your costs down.

Why Go For Flash Drives Of This Size?

• Affordable in bulk: You get more bang for your buck when you order these in larger quantities.

• Light content, easy to share: Ideal for distributing a few key files, such as PDFs or brochures.

• Perfect for quick impressions: Even if the content is minimal, your logo on these drives will still make a lasting impression.

16GB – 32GB

For many businesses, the 16GB to 32GB range is the ideal storage capacity. It’s large enough to hold videos, high-quality product images, or multiple presentations, without being too large to be impractical for everyday use.

Which Audience Does This Flash Drive Size Work Best For?

• Corporate offices: If you need to share training videos, product demos, or internal documents, this size works well.

• Educational institutions: These sizes are perfect for distributing lecture videos, study guides, or other large files.

• Creative professionals: Whether it’s design portfolios or high-res images, 16GB to 32GB provides the storage you need.

Why Go For Flash Drives Of This Size?

• More storage for larger files: It’s enough space for multimedia content like videos or images without going overboard.

• Good balance of cost and value: Still affordable, but with a bit more flexibility for businesses that want to share richer content.

• High utility: This size is practical enough that the recipient will likely use it long after they’ve received it, making it a smart investment.

64GB and Above

If you want to make a statement and offer something more substantial, consider a 64GB or larger drive. These drives are ideal for businesses that need to share large amounts of content, such as product catalogues, software, or entire video libraries.

Who is this size good for?

• Tech companies: Do you need to distribute software packages or large demos? These drives give you the space to do it.

• Creative agencies: A portfolio full of high-resolution photos or videos? This is your size.

• Corporate gifts: These drives are ideal for high-end corporate gifts that offer clients something valuable and practical.

Why Go For Flash Drives Of This Size?

• Premium feel: Larger drives are more likely to be kept and used for the long haul, especially when they’re filled with valuable content.

• Unmatched storage: If you need to share detailed product catalogues, full-length videos, or software packages, these drives have the space for it.

• Elevates your branding: A high-capacity USB drive stands out, offering a sense of luxury and quality that demonstrates your care for your brand's impression.

Tips for Choosing the Right Flash Drive Sizes

Not sure what USB size to go with for your campaign? Here are a few key things we tell our clients to keep in mind when deciding:

1. What are you storing?

Consider the types of files you'll be storing on the drives. A 4GB USB drive is perfect for simple content, such as a digital brochure or PDF business card. But if you're sharing a product video, large images, or a software demo, you'll need more space—consider 16GB or even 64GB.

2. Who are you giving it to?

If you're handing out thousands at a trade show, smaller sizes will help keep costs down while still making a good impression. But if it's for VIP clients, staff incentives, or corporate gifts, larger-capacity custom metal flash drives add more value and feel more premium.

3. What’s your budget?

Smaller USBs are cost-effective for bulk giveaways. But if you’re aiming for something a bit more impressive, larger drives provide more storage and are seen as higher-quality gifts—ideal when you want to stand out.

Final Thoughts: Why USB Size Matters

USB flash drives are a practical, cost-effective promotional product. Picking the right size helps you get the most value out of your investment, whether that’s simple 4GB drives for quick handouts or high-capacity 64GB drives for important clients.
