DaVinci Resolve Needs a Better Drive Than Your MacBook

Resolve is hungry for throughput, and your internal SSD is running out of room.

DaVinci Resolve is one of the most capable editing and colour grading applications available. It is also one of the most demanding when it comes to storage. The free version alone can handle 4K timelines, professional colour grading, Fusion visual effects, and Fairlight audio, all of which assume that your storage can keep up. For many editors working on a MacBook, the internal SSD becomes the bottleneck long before the processor or GPU does.

The problem has two dimensions: capacity and throughput. A MacBook's internal SSD is fast enough for most workflows, but it fills up quickly when you're working with raw footage. A single day of shooting in BRAW or ProRes can produce hundreds of gigabytes. A week-long project can consume a terabyte or more. The base-model MacBook Pro ships with 512 GB of storage, and even the higher-tier configurations top out at a few terabytes, which still isn't much when you're juggling multiple active projects.

Throughput becomes the sharper issue when you move to external storage. The moment files live on an external drive, the connection between that drive and your Mac determines whether playback is smooth or stuttering.

Understanding Resolve's storage appetite

DaVinci Resolve reads media from disk in real time during playback. Unlike some applications that can buffer aggressively or work from low-resolution proxies by default, Resolve is designed to give you a full-quality image in the viewer. This is particularly true in the Colour page, where you need to see exactly what the final grade looks like, and in Fusion, where compositions often reference multiple high-resolution layers simultaneously.

The throughput Resolve needs depends on the codec, resolution, and bit depth of your media. Uncompressed 4K video at 10-bit colour depth requires roughly 1.2 GB/s of sustained read speed. ProRes 4444 at 4K is less demanding but still needs around 300 to 400 MB/s for comfortable real-time playback with headroom. BRAW and other compressed raw formats sit somewhere in between, depending on the compression ratio and the complexity of the debayering.

For a single stream, a modern internal SSD can handle this comfortably. Apple's internal drives in recent MacBook Pro models deliver sequential read speeds well above 3 GB/s. The trouble starts when you layer multiple streams on the timeline, add a complex node tree in the Colour page, or composite several clips in Fusion. Resolve then needs to read from multiple files simultaneously, and sustained throughput matters more than peak speed.

The capacity constraint is easier to grasp. A 1 TB internal SSD can hold perhaps two or three projects' worth of raw 4K footage before you start making difficult decisions about what to keep locally. Editors who work on multiple projects in parallel, or who need to revisit older projects for revisions, quickly find themselves spending time shuffling files between drives rather than editing.

The external drive landscape

The conventional answer to both problems is an external drive. The options, in rough order of performance, look like this.

USB 3.0 mechanical hard drives are cheap and spacious but too slow for real-time playback of anything beyond compressed HD footage. Sustained read speeds of 100 to 150 MB/s are typical, which means dropped frames and stuttering the moment you try to scrub through a 4K timeline.

USB 3.1/3.2 SSDs are a meaningful step up. A good USB-C SSD can deliver 800 to 1,000 MB/s, which is enough for many Resolve workflows with compressed codecs. These drives are portable and reasonably priced for capacities up to about 2 TB, after which costs climb steeply.

Thunderbolt SSDs and NVMe enclosures offer the best external performance, with throughput that approaches or matches the internal drive. Sustained speeds of 2,000 to 3,000 MB/s are achievable with the right combination of enclosure and drive. The trade-off is cost: a 2 TB Thunderbolt NVMe setup can run to several hundred pounds, and 4 TB or larger configurations push well past that.

RAID arrays, whether Thunderbolt-attached or network-connected, offer both high throughput and large capacity. They are the standard in professional post-production facilities. They are also expensive, heavy, and not something you carry to a coffee shop.

Each of these options requires a purchase, physical management, and a backup strategy. Drives fail. Cables get lost. RAID arrays need monitoring. The storage itself becomes a project within the project.

What cloud streaming changes

Fabric's cloud drive (https://fabric.so/features/your-cloud) offers a different approach. Instead of storing media locally or on a physical external drive, your files live in the cloud and stream to your machine on demand. Resolve sees the files as if they were on a local drive, but the data comes over the network rather than from a disk sitting on your desk.

This model solves the capacity problem entirely. There is no local drive to fill up. Your media library can grow to whatever size your projects demand without requiring new hardware purchases or file-shuffling rituals. Multiple projects, archived footage, b-roll libraries: all of it is accessible without occupying space on your MacBook's SSD.

For throughput, the picture is more nuanced, and it's worth being specific about where cloud streaming works well and where it has limitations.

Where cloud streaming fits Resolve workflows

Browsing and selection is one of the strongest use cases. When you're reviewing footage to decide what goes into the timeline, you're scrubbing through clips, watching sections at speed, and making selects. This kind of work is less sensitive to occasional latency than real-time grading. Fabric's cloud drive handles this well, letting you browse your full library without downloading anything first.

Review and approval workflows also benefit. When a director or client needs to see a cut, sharing media through Fabric's publish feature (https://fabric.so/features/publish) creates polished shareable pages with link analytics. This removes the need to export, upload to a separate platform, and send links, and it keeps everything within a single system.

Rough cuts and offline editing with proxy media work comfortably over cloud streaming. Many Resolve workflows already use an optimised media or proxy pipeline, where lower-resolution versions of the footage are used during editing and the full-resolution files are linked only for final output. Cloud-streamed proxies are lightweight enough that network throughput is rarely a constraint.

Assembly edits and lighter timeline work with compressed codecs like H.264 or lower-bitrate ProRes are also well-suited. These formats demand less throughput per stream, and Fabric's streaming can keep up with the demands of a timeline that isn't pushing extreme data rates.

Fabric's semantic search (https://fabric.so/features/search) adds something that no local drive can offer. When you need to find a specific clip, you describe what you're looking for rather than navigating a folder hierarchy. Searching for "close-up of hands typing on a keyboard" across your entire library is faster than manually browsing through bins, regardless of how well-organised your folders are. This is particularly valuable in Resolve, where the Media page's browsing tools are designed for files that are already reasonably well-sorted.

Where local cache still matters

Heavy colour grading in Resolve's Colour page is one of the most storage-intensive tasks in post-production. A complex node tree with multiple secondaries, power windows, and noise reduction can require sustained high-throughput reads from the source media while simultaneously writing to the gallery and cache. When you're doing frame-by-frame grading on a high-budget project, you want the source media on the fastest storage available. Cloud latency, even in small amounts, can introduce delays in the viewer response that disrupt the grading process.

Fusion compositions, particularly those involving multiple high-resolution inputs, particle systems, or 3D rendering, place similar demands on storage throughput. Fusion reads from disk aggressively, and its real-time preview depends on consistent low-latency access to all source files. For complex Fusion work, local media is the safer choice.

Final delivery and rendering can also benefit from local storage. When Resolve is writing a DPX sequence or a high-bitrate master file, the write speed to the output drive matters. This is less about where the source media lives and more about where the output goes, but it's worth noting that the render pipeline works best when both input and output are on fast, local storage.

Fairlight audio work in Resolve is generally less demanding on storage throughput, as audio files are small relative to video. Cloud streaming handles audio projects comfortably.

A practical hybrid approach

The most effective workflow for many editors is a hybrid model. Keep the project you're actively grading or compositing on local or Thunderbolt-attached storage for maximum responsiveness. Use Fabric's cloud drive for everything else: your broader media library, archived projects, b-roll collections, reference footage, and any project that isn't in the intensive finishing stage.

This approach means you only need enough local fast storage for one or two active projects at a time, rather than your entire library. When a project moves from editing into colour, you pull the relevant media into local cache. When grading is done and the project moves to archive, the files go back to the cloud, freeing local space for the next project.

Fabric's connections feature (https://fabric.so/connections) integrates with services like Google Drive, Dropbox, and Frame.io, so your existing cloud storage becomes part of the same searchable library. If footage is coming from a client's Dropbox or a production's Frame.io workspace, Fabric can connect to it directly rather than requiring a separate download-and-organise step.

Smart organisation (https://fabric.so/features/smart-organization) auto-tags and categorises media as it enters your library, which helps maintain order across a growing collection. When you're working across multiple Resolve projects, having your media well-categorised outside of Resolve's own project databases makes it easier to find and reuse assets.

Annotations (https://fabric.so/features/annotations) provide timestamped notes on video and audio, which is useful for marking selects, noting issues, or flagging moments for the colourist. These notes persist with the file in Fabric and are visible to anyone on the team with access, complementing Resolve's own marker system.

The cost comparison

A 2 TB Thunderbolt 4 NVMe SSD typically costs between 200 and 400 pounds. A 4 TB unit is often double that. RAID enclosures with enough capacity for a serious post-production library run into four figures. These are one-time purchases, but they come with ongoing costs: backup drives, replacement when hardware fails, and the time spent managing it all.

Fabric's cloud drive converts that capital expense into a service cost and removes the physical management overhead. The comparison isn't purely financial; it's also about the difference between maintaining hardware and having storage that simply works. For freelance editors and small studios, removing the need to buy, maintain, and back up physical drives is a meaningful simplification.

The AI assistant (https://fabric.so/features/ai-assistant) adds another dimension to how you interact with your media. Beyond searching, you can ask questions about your library and get answers that draw on the content itself. This goes beyond what any local drive, however fast, can offer.

Making the decision

The right storage setup for DaVinci Resolve depends on the kind of work you do most. If you spend the majority of your time in the Colour page doing high-end grading, fast local storage remains essential for your active project. If most of your work is editing, assembly, review, and delivery, cloud streaming handles the day-to-day and eliminates the capacity constraints that make MacBook storage feel so limited.

For many editors, the answer is both. A modest amount of fast local storage for the finishing stage, and a cloud-based library for everything else. That combination gives you the responsiveness Resolve needs for demanding tasks and the capacity and searchability that make managing a growing media library sustainable over time.

Resolve's storage demands are real, and they aren't going to decrease as cameras continue to push higher resolutions, wider colour gamuts, and higher frame rates. Building a storage strategy that scales with those demands, without requiring a proportional increase in hardware spending, is worth thinking about before your next drive fills up.

Frequently asked questions

Can DaVinci Resolve read files directly from Fabric's cloud drive?

Yes. Fabric's cloud drive (https://fabric.so/features/your-cloud) presents files to your operating system as if they were on a local drive. Resolve can open, browse, and play media from this virtual drive without any special plugin or configuration.

Will I get real-time playback of 4K footage over cloud streaming?

It depends on the codec and your internet connection. Compressed formats like H.264, H.265, and lower-bitrate ProRes can play back in real time over a strong broadband connection. Higher-bitrate formats like ProRes 4444 or RAW may require caching for smooth real-time playback, particularly in the Colour page with complex node trees.

Does Fabric work as a replacement for a Thunderbolt SSD?

For editing, assembly, review, and lighter workflows, Fabric's cloud drive can replace an external drive entirely. For heavy colour grading and Fusion compositing, a fast local drive still provides the most reliable real-time performance. Many editors use both: cloud storage for their library and local storage for the active finishing project.

What internet speed do I need for cloud streaming to Resolve?

A connection of at least 100 Mbps is a reasonable baseline for working with compressed 4K media. Faster connections provide more headroom for multi-stream timelines and higher-bitrate codecs. Fibre connections of 500 Mbps or above offer the most comfortable experience.

Does Fabric support BRAW, ProRes, and other professional codecs?

Fabric handles a wide range of professional media formats. Files are stored and streamed in their original format, so Resolve works with them as it would with any locally stored media.

Can I use Fabric's search to find clips and then bring them into Resolve?

Yes. Fabric's semantic search (https://fabric.so/features/search) lets you describe what you're looking for in plain language. Once you find the right clip, it's accessible through the cloud drive, so you can import it directly into your Resolve project.

Does Fabric work offline for Resolve projects?

Fabric requires an internet connection. If you need to work without connectivity, you'll want the media for your active project cached locally. Fabric works best as the central library and archive, with local storage reserved for the project you're editing right now.

How does Fabric compare to a NAS for DaVinci Resolve?

A NAS provides local network storage with throughput that depends on your network infrastructure. A well-configured 10GbE NAS can match or exceed cloud streaming speeds. Fabric's advantages are in searchability, automatic organisation, and the elimination of hardware management. A NAS requires setup, maintenance, and physical space; Fabric requires an internet connection.

Can my colourist and I both access the same media through Fabric?

Yes. Fabric is designed for team use. Multiple team members can access the same media library, and annotations (https://fabric.so/features/annotations) left by one person are visible to others. This makes it easy for an editor and colourist to share footage and notes without manually transferring drives.

Does Fabric's cloud drive work with Resolve's proxy workflow?

Fabric can store and stream both your original high-resolution media and proxy files. You can set up Resolve's proxy workflow as usual, with the proxies streaming from Fabric for editing and the full-resolution files available for final output.
