For a large photo library copied periodically from one computer, start by checking the library size against a portable hard drive’s capacity. Consider a portable SSD if you will carry the copy or transfer files often, provided your computer and cable can support the connection; a NAS makes more sense when several devices need a central archive and you can manage its disks and backups. Whichever you choose, keep a separate copy rather than making one local device the only place your photos live.
Check that the storage can hold the downloaded photos and videos, then plan how you will check and find them later. For Amazon Photos, Amazon Customer Service says you can download selected items but not an entire album as an album.
Choose a connection and file format that work with the computers that will use the drive. Apple Support describes formatting a disk for use with both Mac and Windows, and warns that reformatting erases its contents.
If the drive could be lost or stolen, consider encryption as well as where to keep a separate backup. Microsoft Support documents encryption for removable drives and the recovery key that may be needed to unlock one; Apple Support says its Disk Utility encryption process requires erasing the drive first.
Measure the library and work out how the files will reach the local copy before comparing drive capacity, connections and access between devices.
Consider it: For a large archive copied periodically from one computer and usually kept at home.
Plan for: A second backup elsewhere; one portable drive is still one physical copy.
Consider it: When you carry the archive or make repeated transfers and the chosen capacity holds your files.
Plan for: Checking the host and cable before relying on a quoted transfer speed. Samsung UK says its T7 Shield speed claim requires USB 3.2 Gen 2 and UASP support.
Consider it: When several household devices need access to a central photo archive.
Plan for: Compatible disks, setup and a separate backup destination; Synology’s DS224+ is a two-bay enclosure, not a substitute for another copy.
| Priority | What to check | Your needs |
|---|---|---|
| Capacity | Measure the files to be copied. Allow room for additions and decide whether this storage must also hold another version. | My complete photo and video library needs to fit, with space for the copies I actually plan to keep. |
| Export and retrieval | Check the source service’s download method, available computer space and whether the resulting files are easy to browse. Amazon Customer Service says Amazon Photos albums cannot be downloaded as whole albums. | I want to locate a photo after the transfer, not just see that a download finished. |
| Device compatibility | Check ports, cables, operating systems and the drive’s file format before copying. Apple Support warns that reformatting erases a disk; Samsung UK says the T7 Shield’s quoted speed depends on the host, cable and UASP. | Both our computers may need to read the copy, or I may transfer files often enough for connection speed to matter. |
| Separate, recoverable copies | Keep another backup apart from the local device. If encrypting a removable drive, check the password and recovery process before relying on it; Microsoft Support says a BitLocker recovery key may be needed to regain access. | If a drive is lost or stops working, I still need a way to retrieve the photos. |
Videos, future additions and any extra versions also take space, so today’s library size may not describe what the backup must hold.
Measure the files you intend to copy and allow for the additions and versions you plan to keep.
Amazon Customer Service says an entire album cannot be downloaded as an album. Selecting and checking files can therefore be a substantial part of a large-library transfer.
Plan downloads in stages, organise the folders on your computer and check files before removing an existing copy.
Samsung UK conditions its T7 Shield’s quoted transfer speed on a USB 3.2 Gen 2 host and cable with UASP support.
Check your computer’s port and the cable you will use before making transfer speed the reason for choosing an SSD.
Apple Support says reformatting erases a device, and its Disk Utility encryption process requires erasing an external drive first. An encrypted copy also needs a workable unlock or recovery method.
Retain a separate copy before changing the drive, then test access and keep recovery information separately and securely.
Seagate’s Expansion Portable line is a reference for a directly attached, large local archive; Seagate UK lists a 5 TB variant.
Samsung’s portable T7 and T7 Shield SSDs are relevant when the local copy will be moved or transferred regularly.
Synology’s two-bay DS224+ represents a central household archive that needs compatible disks and configuration.
These portable SSDs and hard drives are options for a local copy connected to a computer. Compare their stated capacities with your library size; a shared NAS is a different setup decision.

A portable SSD to consider for repeated transfers if 2 TB accommodates the library and planned additions. The product name specifies USB Type-C 3.2 Gen 2; check the computer connection before relying on transfer speed, and retain another backup.

This portable hard drive is an option for a large copy in a Mac-focused setup, provided 5 TB covers the files and planned growth. If Windows must also access it, check the intended file-format and driver workflow before copying.

This portable hard drive offers a stated 5 TB capacity for a computer-based local copy. Compare that capacity with the archive and check the drive’s format before using it across Windows and Mac; Apple Support warns that reformatting erases existing data.

This USB Type-C 3.2 Gen 2 portable SSD is worth considering for a carried copy only if its stated 1 TB accommodates the full library and planned additions. Check the computer connection and the security method if the copy needs encryption.

This portable SSD is another 2 TB option for a local copy that may travel. Check that the complete library fits, then confirm its connection, file format and any required encryption method for your devices.
No. Amazon Customer Service says albums cannot be downloaded as entire albums: open an album and select the pictures to download. For a large library, organise downloads on a computer and check the files before copying them to external storage.
Keep the original downloaded files where possible, then open a sample of photos and videos to check the export. Amazon Customer Service lists supported types including JPEG, PNG, HEIC and ProRaw photos and MP4 and QuickTime videos, but format support alone does not confirm that every item transferred.
It can, if its format and connection suit both computers. Apple Support describes formatting an external disk for use with Mac and Windows; check the exact drive first, and keep another copy before reformatting because the process erases the disk.
Consider encryption if the drive could be lost or stolen, but arrange recovery before depending on it. Microsoft Support documents BitLocker for removable drives and says its recovery key may be needed to regain access; Apple Support says encrypting an external drive through Disk Utility requires erasing it first.
No. A NAS can give household devices a central place for files, but it still needs a separate backup destination. Synology documents using Hyper Backup to copy NAS data to destinations such as external storage, another NAS, file servers and cloud services.
