Choosing storage for Call of Duty: Warzone
Warzone can run from either an SSD or a hard disk drive, but the difference is noticeable beyond the initial loading screen. An SSD makes the game faster to install, launch, update, and load into a match. It can also reduce texture-streaming pauses and short stutters when the game pulls large amounts of data during play.
A mechanical hard drive is still usable if cost is the priority or you already own one with plenty of free space. It is the weaker choice for a primary gaming drive, particularly on a modern PC with a fast processor and graphics card. The slower storage can become the part of the system that makes you wait.

For most players, a 1TB SSD is the sensible minimum upgrade. A 2TB drive is more comfortable if Warzone shares the drive with several other large games.
SSD vs HDD performance in Warzone
| Task | SSD | HDD |
|---|---|---|
| Launching Warzone | Usually much faster | Longer startup and menu waits |
| Loading into a match | Shorter loading times | Often noticeably slower |
| Installing updates | Faster file writes and verification | Can take substantially longer |
| Texture and asset streaming | Better response under load | More likely to pause or hitch |
| Noise and power use | Silent and low-power | Audible spinning and seeking |
| Cost per terabyte | Higher | Lower |
Do not expect an SSD to increase average FPS in the same way as a faster graphics card. Once a match is running and all required assets are in memory, frame rate is mostly determined by the CPU, GPU, RAM, and game settings. The SSD’s advantages are loading speed, consistency, and reduced asset-loading delays.
The difference is especially clear with a SATA SSD compared with an HDD. An NVMe SSD is faster again in sequential transfers, but Warzone does not normally make a SATA SSD feel unusable. If your PC has an open M.2 slot, an NVMe drive is a convenient and modern choice. Otherwise, a 2.5-inch SATA SSD is still a worthwhile upgrade.
How much storage space does Warzone need?
Warzone’s installed size changes with seasons, patches, language files, optional content, and the launcher you use. Plan for roughly 100GB or more for the game and its current files, rather than buying a drive with only that much capacity. Updates may need additional temporary working space while files are unpacked, replaced, or verified.
Keep at least 15% to 20% of the SSD free. A nearly full drive can slow down during large updates and gives Windows less room for temporary files, shader caches, and virtual memory. On a 500GB drive, Warzone can consume a large portion of usable capacity once Windows and other applications are installed.
A 1TB SATA SSD is a practical budget choice for Warzone and a few other games. Choose a 2TB NVMe SSD if you regularly keep large games installed and want room for future updates.
When an HDD is still good enough
An HDD is fine for storing games you play occasionally, backups, recordings, installers, and a Steam or Battle.net library that does not need to load quickly. It is also reasonable for a secondary drive when your budget is tight. You may save money by keeping the HDD for bulk storage and installing Warzone on a smaller SSD.
The cheaper option makes the most sense when you play infrequently, tolerate longer loading screens, or are upgrading an older PC where the CPU and GPU are already limiting performance. An HDD will not automatically cause low FPS or prevent Warzone from running.
Its weaknesses appear during heavy drive activity. A hard drive has moving heads and spinning platters, so many small reads are slow compared with solid-state storage. Background tasks such as Windows updates, antivirus scans, downloads, or recording gameplay can make loading and stuttering worse. Older or nearly full HDDs are particularly poor choices.
Which SSD should you buy?
For a desktop, first check whether your motherboard has an available M.2 slot and whether it supports NVMe drives. For a laptop, check the manual or manufacturer specifications before buying; some systems use only a 2.5-inch SATA drive, while others accept only M.2 storage. A 2.5-inch SATA SSD is the straightforward replacement for a laptop or desktop HDD.
For gaming, a reputable TLC-based SSD with a capacity of 1TB or more is generally a better target than chasing the highest advertised sequential speed. DRAM-less budget models can work, but sustained writes during large game installations may slow sharply after their cache fills. This matters more for frequent installs and updates than for ordinary match loading.
Do not pay a large premium for a top-end PCIe 5.0 drive solely for Warzone. A good PCIe 3.0 or PCIe 4.0 NVMe SSD already provides very fast game loading, and the difference in actual match startup may be modest. Spend the saved money on capacity, memory, or cooling if those parts are weak.
How to move Warzone from an HDD to an SSD
Install the SSD, initialize and format it in Windows if it is new, and confirm it appears in File Explorer. The simplest approach is to use the launcher’s built-in move function. In Battle.net, open the game settings and choose the option to locate or move the installation, depending on the current launcher version. Steam users can add a library folder on the SSD and move the installed files through the game’s storage settings.
If the launcher cannot move the game cleanly, uninstalling and reinstalling it to the SSD is safer than manually dragging folders. Keep your account details and launcher credentials available, and avoid deleting the old installation until the new copy starts successfully. Ensure the SSD has enough free space for the game plus temporary update files.
After moving the game, set the launcher and Windows to avoid installing new updates on the HDD. You can keep screenshots, recordings, and older games on the hard drive. If Warzone still stutters from an SSD, check graphics settings, shader compilation, RAM capacity, temperatures, drivers, and background programs before buying another drive.
