How each alternative compares
Kingston A400 960GB 2.5-Inch SATA SSD
The Kingston A400 replaces the My Passport’s external USB interface with a 2.5-inch SATA III connection for internal installation. It offers 960 GB of capacity, significantly more than the 256 GB model, but lacks the portability and hardware encryption of the WD drive. You gain a lightweight 1.44-ounce form factor suitable for desktop or laptop upgrades, but you lose the pocket-sized convenience and secure password protection. This drive suits users who need large internal storage rather than external backup solutions.
Transcend 512GB PCIe 3.0 NVMe M.2 SSD
The Transcend 512GB NVMe M.2 SSD shifts from external USB to internal PCIe 3.0 connectivity. It delivers read speeds up to 1,800 MB/s, far exceeding the 540 MB/s limit of the My Passport. You get integrated thermal management and a compact M.2 2280 form factor, but you sacrifice the external shell and hardware encryption features. This option is ideal for users upgrading compatible M.2 systems who prioritize speed and capacity over portable, secure external storage.
SanDisk SSD Plus 1TB 2.5-Inch SATA SSD
The SanDisk SSD Plus 1TB uses a 2.5-inch SATA III interface for internal mounting, unlike the My Passport’s external USB connection. It provides 1 TB of storage, offering much higher capacity than the 256 GB WD drive. While it includes shock resistance for standard desktop upgrades, it lacks the portable form factor and hardware encryption of the original. This drive is best for users needing substantial internal space for desktop systems without requiring external portability or secure file protection.
Addlink S20 1TB 2.5-Inch SATA SSD
The Addlink S20 1TB SATA SSD replaces the My Passport’s external design with an internal 2.5-inch SATA III form factor. It offers 1 TB of capacity and up to 500 MB/s read speeds, matching the WD drive’s performance but with far more storage. It features SLC caching and 3D NAND for practical performance in laptops and consoles. You lose the USB portability and hardware encryption, making this a better choice for internal upgrades where capacity and direct motherboard connectivity matter more than external access.
Addlink S70 Lite 1TB Gen3 NVMe SSD
The Addlink S70 Lite 1TB Gen3 NVMe SSD moves from external USB to internal PCIe 3.0 connectivity. It achieves read speeds up to 3,200 MB/s, significantly faster than the 540 MB/s My Passport. You gain 1 TB of internal storage and 3D NAND technology for gaming and desktop upgrades, but you lose the portable external shell and hardware encryption. This drive is suited for users who need high-speed internal performance and large capacity rather than secure, pocket-sized external storage.
Transcend 512GB M.2 SATA SSD with DRAM
The Transcend 512GB M.2 SATA SSD shifts from external USB to internal M.2 SATA III connectivity. It provides DRAM cache for improved performance and 512 GB of capacity, double the WD drive’s storage. However, it lacks the external portability and hardware encryption features of the My Passport. You get a compact M.2 2280 form factor suitable for compact builds, but you sacrifice the convenience of USB connectivity and secure password protection. This option fits users prioritizing cache performance in internal M.2 slots.

Frequently asked questions
Can I use a SATA SSD as a portable external drive like the My Passport?
You can use a SATA SSD externally, but you need an additional enclosure. The Kingston A400 and SanDisk SSD Plus are 2.5-inch SATA drives designed for internal mounting. To use them externally, you must buy a separate USB-to-SATA adapter or enclosure. This adds bulk and cost, removing the compact, all-in-one portability of the original My Passport SSD.
What is the fastest NVMe alternative for internal upgrades?
The Addlink S70 Lite is the fastest option listed, offering PCIe 3.0 read speeds up to 3,200 MB/s. It uses an M.2 2280 form factor and fits directly into compatible motherboard slots. This speed is significantly higher than the My Passport’s 540 MB/s external USB transfer rate, making it ideal for high-performance internal desktop or laptop builds.
Is there an NVMe drive with DRAM cache for better performance?
Yes, the Transcend 512GB M.2 SATA SSD includes DRAM cache. While it uses the SATA III interface rather than NVMe, the DRAM cache helps manage data more efficiently than cache-less drives. It provides a compact M.2 2280 form factor, offering a different upgrade path for users who need reliable performance in a small internal drive format.
Which alternative offers the most storage capacity?
The SanDisk SSD Plus and Addlink S20 both offer 1TB of capacity. This is four times the storage of the 256GB My Passport. The SanDisk model is a 2.5-inch SATA drive, while the Addlink S20 is also a 2.5-inch SATA drive with SLC caching. Both provide substantial internal storage for large file libraries or system backups.
Does the Transcend NVMe drive include thermal management?
Yes, the Transcend 512GB PCIe 3.0 NVMe SSD features integrated thermal management. This helps maintain consistent performance during sustained writes by managing heat buildup. It delivers read speeds up to 1,800 MB/s in a standard M.2 2280 size, making it a reliable internal upgrade for systems that support PCIe Gen3 x4 connections.
Can I replace a laptop hard drive with these SSD alternatives?
Several listed drives are suitable for laptop replacements. The Kingston A400, SanDisk SSD Plus, and Addlink S20 are all 2.5-inch SATA drives that fit standard laptop drive bays. The Addlink S70 Lite and Transcend M.2 drives fit laptops with M.2 slots. You must verify your laptop supports the specific interface, whether SATA or PCIe NVMe.
Is hardware encryption available in these SATA or NVMe alternatives?
The product data for the listed alternatives does not mention hardware encryption capabilities. The original My Passport SSD highlights this feature for secure external storage. The Kingston, SanDisk, Addlink, and Transcend drives focus on storage capacity, interface speed, and form factor. If encryption is critical, you may need to use software-based encryption on the host system.
