Complete Overview & Search Intent

Storage real estate is one of the most critical logistical bottlenecks in contemporary PC and console gaming. With extraction shooters, a sudden update or storage bottleneck can lock you out of a scheduled squad raid, corrupt high-value extraction runs, or induce micro-stutter mid-firefight. Players searching for how many gigabytes ARC Raiders is require more than just an arbitrary base number—they need exact breakdowns of download sizes, final uncompressed disk footprints, platform-specific differences, and the mandatory storage infrastructure required to run Embark Studios' intense, physics-heavy sci-fi survival title smoothly.

ARC Raiders is built from the ground up on modern architecture, utilizing Unreal Engine 5's cutting-edge pipeline, including heavy server-client replication, complex dynamic physics for falling ARC machines, and high-fidelity volumetric environments. Because Embark Studios prioritizes rapid deployment cycles and detailed environmental assets across maps like the Calabretta Peninsula and subterranean Rust Belt facilities, the game's file footprint requires deliberate preparation.

Whether you are budgeting space on a 512 GB handheld drive, an internal PS5 expansion card, or a high-performance PCIe Gen 4 NVMe PC drive, this tactical technical breakdown delivers the exact gigabyte requirements and drive optimization protocols you need before dropping into the Rust Belt.

Deep Dive Mechanics & Technical Specs

Understanding ARC Raiders' file footprint requires dissecting how Embark Studios packages, extracts, and streams game data during active deployments. The game does not operate like traditional linear shooters where assets are pre-loaded into monolithic RAM structures; instead, it relies heavily on continuous virtual asset streaming.

Unreal Engine 5 and Virtualized Mesh Data

ARC Raiders makes extensive use of high-density asset geometry. While this delivers breathtaking post-apocalyptic vistas and photorealistic machine husks, it means texture packs, physics collision hulls, and localized audio tables occupy substantial disk space. Unlike games that compress audio to low bitrates, ARC Raiders utilizes directional, high-dynamic-range soundscapes essential for pinpointing stealthy Snitch drones or distant Sentinel footfalls. Uncompressed and lightly compressed sound banks make up nearly twenty percent of the game's total footprint.

The Impact of DirectStorage and NVMe Throughput

While ARC Raiders can technically be installed on older SATA-based solid-state drives, doing so puts you at an extreme tactical disadvantage. The game leverages asynchronous I/O read operations designed for NVMe drives. When you rapidly transition from open sunlit valleys into deep industrial bunker complexes, the engine hot-swaps high-resolution asset clusters. On slower drives, this manifests as asset pop-in, weapon model load delays, and frame-time spikes that can get you eliminated during sudden ambushes.

Delta Patching and Drive Allocation Bloat

Embark Studios uses a delta-patching system on PC. When a patch drops, the launcher verifies existing file checksums, creates temporary backup archives of the affected sectors, writes the new binaries, and re-packs the container. This means that even a minor 3.5 GB balance patch can demand up to 40 GB of temporary workspace while the engine rebuilds pak-chunk files. If your drive is hovering under ten percent free capacity, patching can grind to a complete halt or throw write-failure errors.

Below is the verified storage requirement breakdown across all officially supported platforms, accounting for download compression, unpack footprint, and necessary headroom.

Note: Measurements reflect live retail builds and standard high-definition texture packages. Future major content expansions will gradually expand these requirements.

Step-by-Step Tactical Walkthrough

To ensure your storage hardware does not bottleneck your raid performance or delay your squad deployment, execute this technical storage optimization walkthrough.

Validating Drive Geometry and File System Health

Before initiating the download, verify your target drive utilizes the NTFS (for Windows) or native APFS/ext4 structure without bad sectors. High-speed multi-threaded downloads from Steam and Epic strain drive controllers.

• Open Windows PowerShell as Administrator.
• Run the storage query command to verify drive health:

  Get-PhysicalDisk | Select-Object DeviceId, FriendlyName, MediaType, OperationalStatus, HealthStatus
  

• Ensure the target drive returns Healthy and displays SSD under MediaType.

Preparing the Steam / Epic Installation Target

• Direct your launcher specifically to an NVMe drive partition with at least 100 GB of free space.
• In Steam: Navigate to Settings > Storage, create a dedicated library folder on your fastest drive, and set it as the default target.
• Clear your Steam Download Cache before starting the ARC Raiders download to prevent chunk corruption: go to Settings > Downloads > Clear Download Cache.

Managing the Windows Paging File

Because ARC Raiders utilizes aggressive asset streaming, running low on system RAM causes memory overflow into the Windows pagefile. If your pagefile is located on a slow secondary mechanical drive, the game will stutter violently.

• Press Win + R, type sysdm.cpl, and hit Enter.
• Navigate to Advanced > Performance Settings > Advanced > Virtual Memory.
• Ensure the paging file is strictly allocated to your fastest NVMe SSD, configured with a system-managed or fixed custom size (minimum 16384 MB if running 16 GB physical RAM).

Post-Installation Shader Compilation Protocol

Once the download completes, launch ARC Raiders and remain in the main operations menu for several minutes. The game silently compiles PSO (Pipeline State Object) disk caches in the background:

• Monitor your task manager; ensure background CPU/Disk utilization stabilizes before hitting Deploy.
• Pre-caching shaders prevents mid-combat frame drops when encountering energy weapons, thermite grenades, or sudden dynamic weather shifts.

Map Locations & Threat Mitigation

Drive speed directly dictates in-game threat survivability. Asset streaming delays do not just cause visual glitches—they fundamentally compromise raid intelligence and combat responsiveness across high-danger drop zones.

The Buried City and Subterranean Bunkers

When navigating the subterranean metro lines and military command stations beneath the Buried City, the game rapidly streams out sunlight lighting models and streams in claustrophobic, volumetric fog systems and interior props. On sub-optimal drives, entering an airlock or blast door can freeze your frame rate for two to three seconds. If a rival squad or a roaming Sentinel machine is waiting inside, this frame freeze guarantees a trip back to Speranza empty-handed. Installing the game on a high-throughput drive eliminates this asset-swap stutter completely.

Long-Range Engagements on Calabretta Peninsula

In wide-open coastal and agricultural sectors, snipers and scout-class Raiders rely on long-distance Level of Detail (LOD) streaming. If your drive cannot feed mesh LODs to your VRAM instantly, rival raiders hiding behind concrete barricades or dilapidated farming equipment may appear to be floating or invisible at 200+ meters, preventing you from identifying cover boundaries and leading to wasted ammunition or lethal counter-fire.

Pro Survival Tips & Stash Strategy

Treat your drive management with the same tactical rigor as your field backpack and stash inventory. Storage mistakes lead directly to missed extraction cycles and dropped connections.

• Never Run Under Fifteen Percent SSD Capacity: Solid-state drives experience write degradation and reduced read throughput as they approach maximum capacity due to SLC cache saturation. Keeping at least 15% of your drive free prevents sudden read-speed drops during active raids.
• Disable Third-Party Drive Indexing During Raids: Background indexing services (such as Windows Search Indexer or automated cloud backups like OneDrive/Dropbox) scanning your game directory can induce severe micro-stuttering. Add your ARCRaiders installation folder to your antivirus and indexing exclusion lists.
• Avoid MicroSD Installs on Handheld PCs: If playing on a Steam Deck, ROG Ally, or Legion Go, do not install ARC Raiders onto a generic MicroSD card (A1/A2). The limited random 4K read speeds will lead to severe audio desynchronization, infinite loading screens at the Speranza deployment gates, and sudden disconnects mid-raid.
• Verify Integrity After Heavy Game Crashes: If your game crashes while loading an extraction instance, immediately right-click ARC Raiders in Steam, select Properties > Installed Files, and choose Verify integrity of game files. UE5 pak files can suffer silent partial write corruption during hard system crashes, leading to subsequent disconnects on specific map sectors.

Frequently Asked Questions (FAQ)

How many gigabytes will I need to download for ARC Raiders on PC?

You will download approximately 32.5 GB of compressed game data on Steam or the Epic Games Store. Upon completion, the installer unpacks this data into a final install footprint of 54.2 GB on your drive.

Can I run ARC Raiders on a traditional mechanical Hard Disk Drive (HDD)?

No. While the installer might allow you to select a mechanical hard drive, the gameplay experience will be virtually unplayable. Unreal Engine 5's asset streaming architecture relies on instantaneous I/O reads. Running ARC Raiders on an HDD results in extreme texture pop-in, minute-long loading screens, severe stuttering, and potential matchmaking timeouts.

Why does ARC Raiders require so much extra free space during updates?

ARC Raiders uses delta patching to minimize actual download bandwidth. However, to apply a patch, your system must unpack existing asset containers, merge the new code or textures, and re-compress the archives. This requires temporary workspace on your drive. Always keep 85 GB to 100 GB of free space available to ensure seamless updates.

Is the file size smaller on PS5 compared to PC?

Yes. ARC Raiders sits at approximately 46.1 GB installed on PlayStation 5, compared to 54.2 GB on PC. This reduced footprint is due to Sony's proprietary hardware decompression block and Kraken compression algorithm, which compresses texture and audio packages more efficiently than standard PC architectures.

Will future DLC and map updates increase the game's file size?

Inevitably. Extraction shooters expand with each competitive season. As Embark Studios introduces new biomes, additional ARC robotic variants, modular weapon attachments, and seasonal cosmetics, the installed file size will gradually expand. Expect the long-term disk requirement to trend toward 70 GB to 80 GB over the game's lifecycle.
