Is Your iPhone’s Storage Full?
It’s a common issue – your iPhone keeps telling you it’s running out of storage space. According to Apple, the average iPhone user now has over 10GB of photos, videos, apps and other data stored on their device. With limited onboard storage options like 64GB or 128GB available on most iPhones, it’s no wonder many users keep bumping up against the upper limits of their phone’s capacity.
When your iPhone storage feels cramped, it’s tempting to consider hardware upgrades like adding an external solid state drive (SSD). But is this possible? Can you increase your iPhone’s storage by plugging in an SSD? Let’s take a closer look…
What is an SSD?
SSD stands for solid-state drive. An SSD is a type of computer storage that uses flash memory to store data persistently (1). SSDs differ from traditional hard disk drives (HDDs) because they have no moving mechanical components. Whereas HDDs store data on spinning magnetic disks, SSDs use microchips and interconnects to save and access data digitally.
Compared to HDDs, SSDs are typically faster, lighter, more durable, and silent. They have much faster access times for reading and writing data since they don’t rely on any physical head movement. SSDs consume less power, generate minimal heat, and are not prone to crashes from vibration or physical shocks (2). However, SSDs used to be considerably more expensive and have lower capacities than HDDs.
The benefits of SSDs over HDDs include:
- Faster boot times and quicker application/file access
- Improved reliability and durability due to no moving parts
- Lower power consumption and operating temperatures
- Lighter weight and quieter operation
iPhone Storage Options
iPhones come with built-in flash storage ranging from 64GB to 512GB depending on the model. This internal storage holds the iOS operating system, apps, photos, videos, music, and other files on the device (https://support.apple.com/en-us/HT201238). When the built-in storage starts to fill up, there are a few options to expand capacity:
– iCloud: Apple’s cloud storage service that can back up photos, videos, documents and other files automatically. iCloud offers 5GB of free storage and paid plans from 50GB to 2TB (https://support.apple.com/en-us/HT201238).
– External hard drives: Portable USB hard drives can connect to iPhones using adapters like the Lightning to USB or USB-C to Lightning cables. This allows offloading files like photos and videos to free up internal storage.
– Cloud storage services: Third-party services like Google Drive, Dropbox, Microsoft OneDrive offer free and paid plans to store files in the cloud.
– Wireless storage: Devices like wireless hard drives and SD cards can create local Wi-Fi networks that the iPhone can connect to for wireless file transfers and backups.
Challenges of Adding an SSD
There are several key challenges to directly connecting an SSD drive to an iPhone:
Physical connection limitations – iPhones do not have standard ports like USB or SATA to allow connecting an SSD directly. At most, iPhones include a Lightning port which does not provide enough bandwidth or a compatible interface for SSD storage. This makes physically connecting an SSD drive impossible without major hardware modifications.
Power draw concerns – SSD drives require much more power than an iPhone battery can provide. Typical SSD drives draw up to 4-5 watts when active, while iPhones are designed to conserve battery life by running peripherals at very low power draws. Trying to run an SSD off the iPhone battery would cause rapid battery drain issues.
According to discussions on the Apple Support Communities forum (https://discussions.apple.com/thread/255224693), users have had issues getting external SSD drives to connect properly or be recognized by iPhones. The Lightning port has bandwidth limitations and many SSDs require too much power to function when connected.
Workarounds
While iPhones do not natively support connecting an SSD drive directly, there are some workarounds using SSD adapters and external SSD drives:
SSD adapters like the Lightning to USB 3 Camera Adapter from Apple allow you to connect USB peripherals like SSD drives to your iPhone. With this adapter, you can plug the SSD drive into the USB port and then connect the adapter to your iPhone via the Lightning port. This gives your iPhone access to data on the external SSD. However, the adapter requires power to function, so you’d need to connect it to a power source like a wall charger while using it.
There are also external SSD drives available with built-in Lightning connectors made specifically for iPhones and iPads. For example, the SanDisk iXpand Flash Drive Luxe has a Lightning connector on one end and a USB connector on the other. This allows you to directly plug the drive into your iPhone’s Lightning port without any adapter. The downside is that these drives are only available in smaller capacities like 128GB or 256GB.

Performance Impacts of Adding an SSD to an iPhone
One of the key considerations when adding an SSD to an iPhone is how it will impact performance, particularly read/write speeds and battery life.
iPhones utilize flash storage, which offers faster read/write speeds than traditional hard drives. However, the read/write speeds can vary depending on the capacity of the storage. According to benchmarks, the higher capacity iPhone models with more built-in flash storage tend to have faster read/write speeds. For example, the 512GB iPhone 14 Pro Max scored a write speed of 1419 MB/s, while the 128GB model scored 1244 MB/s in testing (Source).
The read/write speeds of a third-party SSD would depend on the specific drive used. Many SSDs are capable of sequential read/write speeds over 500 MB/s. However, the custom NVMe protocol used by iPhones may limit the performance of an added SSD compared to its rated speeds (Source). There is not sufficient data to predict exact speeds of adding an SSD to an iPhone.
In terms of battery life, utilizing flash storage instead of a spinning hard drive provides some advantages. However, adding an externally connected SSD could still potentially drain the battery faster than the built-in storage alone. The additional energy required to power and connect to the external SSD can reduce battery life.
Security Considerations
When considering adding external SSD storage to an iPhone, it’s important to evaluate the potential security risks. iPhones have robust built-in protections to secure data and prevent unauthorized access.
All data stored on an iPhone is encrypted by default using Apple’s Secure Enclave, an isolated security chip that protects the encryption keys. This prevents unauthorized access to data even if the device is lost or stolen. Adding an external SSD could potentially bypass these protections, leaving data more vulnerable.
Connecting an external drive also presents a physical security risk. If an SSD is small and portable enough to connect to an iPhone, it could also be easily removed or stolen along with the phone. This creates further opportunities for data theft.
Overall, while adding external storage may seem convenient, it is safer to rely on the built-in protections of the iPhone and utilize cloud backups for more capacity. Circumventing the iPhone’s security features could needlessly put sensitive user data at risk.
Cost Analysis
SSDs offer significant performance benefits over traditional hard disk drives, but they also come at a higher price point. The cost of SSDs has dropped dramatically over the years, but they are still more expensive than HDDs in terms of cost per gigabyte of storage.
As of 2023, a 1TB SSD from a reputable brand costs around $80-120 depending on factors like form factor and read/write speeds (Source: amazon.com). In comparison, a 1TB HDD costs around $40-60. So the SSD is still about 2-3 times more expensive per gigabyte.
Beyond the drive itself, you would need an adapter or enclosure to connect the SSD externally to an iPhone. These tend to cost $10-30 depending on the exact interface and speed. So factoring in adapter cost on top of the SSD itself, expect to spend around $100-150 to add external SSD storage to an iPhone.
While this is not an insignificant cost, the performance and reliability improvements of an SSD over an HDD may be worth it for some iPhone users who require expanded storage and optimal speed for intensive mobile workloads involving large media files, for example.
Alternatives to Adding SSD
While adding an SSD to an iPhone is not straightforward, there are some alternatives that can help increase your iPhone’s storage capacity without requiring disassembly or hardware modifications:
One of the most popular options is using iCloud storage. iCloud provides online storage that can be used to store photos, videos, documents and other files from your iPhone. By keeping files in iCloud rather than directly on your device, you can free up local storage space on your iPhone. iCloud plans start at $0.99 per month for 50GB of storage and go up to 2TB for $9.99 per month.
External hard drives and flash storage devices like USB drives are another way to effectively expand the storage capacity of your iPhone. Using the Files app and storage accessories that are compatible with iOS, you can store photos, videos and documents on an external drive and access that content from your iPhone when needed. Prices for external storage vary considerably based on capacity and transfer speeds.
While not as seamless as additional internal SSD storage, using iCloud and external storage can meaningfully increase the effective storage capacity for your iPhone without hardware modifications.
Conclusion
Summary
In summary, an SSD cannot simply be plugged into an iPhone like an external hard drive. iPhones lack the physical ports and software support to directly connect an SSD. While there are some cumbersome workarounds like using external SSDs with adapters or jailbreaking, they come with major drawbacks for performance, security, and usability.
Recommendations
The recommended options are:
- Get an iPhone model with more internal storage
- Use iCloud or other cloud storage services to store photos, videos, and documents
- Back up iPhone to a computer or external hard drive occasionally
- Use the Files app to access documents stored on services like Dropbox or Google Drive
- Delete unused apps and media to free up space
Trying to use an external SSD with an iPhone involves too many compromises compared to these simpler alternatives that work within the iPhone’s limitations.
