Comparison Summary
For everyday transfers across old and new iPhones, the 256GB SanDisk Phone Drive offers both Lightning and USB-C; its USB-C connection can use Files, while Lightning copying uses the SanDisk app. Its product documentation also describes app-based automatic backup, making it the most rounded pick for a mixed-iPhone household. The Lexar ES5 is the stronger match for a compatible Pro iPhone video setup: its 2TB capacity, magnetic attachment, and stated recording support serve a different job, but USB-C connectivity and recording conditions rule it out as a simple Lightning backup stick. For USB-C file transfers between phone and computer without a dedicated iPhone backup app, consider the SSK SD301’s USB-C and USB-A ends. (documents.sandisk.com)
Buying Guide
Sizing and Capacity
Think in terms of the library you intend to move, not just your iPhone’s capacity. The 128GB Techkey suits a smaller selection of photos and documents; 256GB sticks give everyday backups more room. The 512GB Puhea and BLANBOK+ drives suit larger libraries that still benefit from a pocketable stick. For ongoing video projects, the 1TB SanDisk Creator and 2TB Lexar SSDs offer more working space. Advertised capacity is not identical to usable space: Puhea’s listing, for example, estimates about 484GB usable on its 512GB drive. Leave room for future files rather than choosing a capacity that only fits today’s collection.
Feature Tradeoffs
Choose the backup method you will actually use. SanDisk’s Phone Drive combines dual iPhone connectors with optional app-managed automatic backup; Techkey, Puhea, and BLANBOK+ emphasize their companion apps for one-tap copying. The SSK SD301 is the cleaner fit when your goal is selecting files in a compatible file manager and moving them to a USB-A computer, rather than setting up an iPhone backup routine. For a shooting rig, the Lexar ES5 and SanDisk Creator attach magnetically but still need a USB-C connection. The Professional Go instead plugs into the phone, avoiding a cable while putting the drive at the port.

Key Specs to Compare
Compare read and write figures separately and keep the connection in view. Lexar rates the ES5 at up to 2,000MB/s in each direction on USB 3.2 Gen 2x2 hardware, explicitly warning that other systems can be slower. The Professional Go is rated up to 1,050MB/s read and 1,000MB/s write; SanDisk rates the Creator Phone SSD at up to 1,000MB/s read and 950MB/s write. These are product ratings, not a promise of that speed on an iPhone. For external ProRes recording, Apple specifies exFAT, a suitable USB 3 cable, and minimum sustained write capability that varies by recording mode; match those requirements to the exact Pro iPhone before treating any headline speed as a recording guarantee.

Setup and Handling Considerations
Check the physical connection and package contents before ordering. The SanDisk Phone Drive has Lightning and USB-C ends, whereas the SSK has USB-C and USB-A: those pairings solve different problems. Puhea supplies a USB-A adapter with its Lightning/USB-C stick. SanDisk supplies a cable for the Creator SSD, and Lexar lists a USB-C male-to-female adapter with the Professional Go. A phone case can affect how securely a direct-plug drive seats, so check clearance, especially with the Professional Go. If a drive does not appear in Files, Apple says external storage needs a single data partition and a supported format, including exFAT or APFS. Some drives can also require additional power through a suitable powered adapter or hub. (americas.lexar.com)
Maintenance and Longevity
Treat a portable drive as one copy, not your only copy. Confirm important files open on the destination before deleting them from Photos, and keep another copy of irreplaceable material. Finish transfers or recordings before unplugging a drive; Lexar specifically warns that disconnecting its ES5 during recording can leave a video unsaved or unplayable. IP65 ratings on the ES5, Professional Go, and Creator SSD make their stated dust- and water-resistance meaningful handling distinctions, not permission to disregard the connector or assume damage is covered. The Professional Go also includes a protective silicone case. (americas.lexar.com)
Reliability Signals
Look for documentation tied to the exact model and capacity. SanDisk identifies the 1TB Creator SSD as SDSSDE62C-1T00-G25 and specifies its connector and sequential speeds; Lexar identifies the 2TB ES5 as LES5XXX002T-RNWNU and states the interface needed for its peak rating. Those details make it easier to check whether an accessory or workflow is appropriate. For app-dependent flash drives, verify that the required app works with your iPhone and that the listing describes the connector you need. A durability rating or limited warranty is useful context, but neither replaces a second copy of your data. (sandisk.com)
How to Compare Reviews
When reading owner accounts, match the exact capacity, iPhone, and task. Feedback about the 256GB SanDisk Phone Drive’s Lightning app workflow is more relevant to a Lightning photo backup than feedback about copying files through its USB-C end. For the Lexar Professional Go, separate reports from iPhone 15 or 16 Pro setups from iPhone 17 reports: this listing says not to use it with iPhone 17, while Lexar’s published product page says compatibility testing for that series is in progress. For the ES5 or Creator SSD, look for the stated iPhone model, recording mode, cable, and file format before applying a recording account to your rig.
Common Mistakes
Do not buy a USB-C-only SSD for a Lightning iPhone on the assumption that a magnetic attachment also provides data connectivity. Do not confuse USB-A computer access on the SSK with Lightning compatibility, or assume that every dual-connector drive works through Files the same way on both ends. Check whether an app is required before moving a large photo library. Finally, distinguish copying an existing video from recording ProRes directly to a drive: the latter depends on a supported Pro iPhone and a qualifying storage setup, not capacity alone.
Frequently Asked Questions
Can I use the same drive with a Lightning iPhone and a USB-C iPhone?
Yes, if the exact drive provides both connections. The SanDisk Phone Drive, Puhea, and listed Techkey sticks do; their app requirements can still differ. A USB-C/USB-A drive such as the SSK SD301 does not directly connect to Lightning.
Will an external drive appear automatically in Files?
A compatible connected drive can appear under Locations in Files, provided its partition, format, connection, and power meet iPhone requirements. Do not assume that an app-based Lightning drive exposes the same workflow as its USB-C connection.
Can any SSD record ProRes directly from my iPhone?
No. Direct external ProRes recording requires a supported Pro iPhone, an appropriate USB-C connection, exFAT formatting, and sufficient write speed for the selected mode. Check the drive’s stated recording support and your exact iPhone and cable before choosing a creator SSD. (support.apple.com)
Does copying photos to a drive immediately free up iPhone space?
No. First confirm the copies are accessible, then delete the originals you no longer want on the phone. If they remain in Recently Deleted, remove them there when you are ready to reclaim that space.
Final Recommendation
Choose the SanDisk 256GB Phone Drive SDIXD0N-256G-GN6NE if your main goal is moving or backing up photos across Lightning and USB-C iPhones. Its connector pairing addresses the broadest everyday compatibility problem, provided you are comfortable using the app for Lightning copying. If you instead have a compatible USB-C Pro iPhone and plan to record sizable video projects, the Lexar 2TB ES5 Magnetic SSD LES5XXX002T-RNWNU is the more appropriate choice; check your recording mode, cable, and host before relying on its stated speeds.
