This list includes internal NVMe SSDs for users who do not need an external enclosure, as well as other portable drives with varying interface standards like USB 3.2 Gen 2. Some options focus on specific platforms like the PS5 or older MacBook Pro models. By comparing these specs, you can find a drive that matches your required capacity, interface type, and physical dimensions without compromising on performance.
How these alternatives compare
Seagate Barracuda Q5 1TB M.2 NVMe SSD
The Seagate Barracuda Q5 is an internal M.2 drive, not an external portable unit like the SSK. It uses QLC NAND and operates on PCIe Gen3, offering lower sustained speeds than the SSK’s Gen4 NVMe performance. You save money by skipping the enclosure and USB interface, but you lose portability. This drive fits desktops and laptops with available M.2 slots. It is a sensible upgrade for standard storage needs where you do not need to move the drive between devices. The SSK remains better for creators who need to transfer large media files on the go.
S Sharkspeed 1TB MacBook Pro Internal SSD
This S Sharkspeed drive is an internal M.2 NVMe SSD designed specifically for MacBook Pro A1708 models. It replaces the original internal storage rather than serving as an external backup drive like the SSK. You gain faster macOS boot times and application loading for older Apple laptops. However, you cannot use it as a portable drive for other devices. The SSK is universal and works with laptops, phones, and consoles. If you have a 2016-2017 MacBook Pro without a Touch Bar, this internal upgrade is the correct choice. For general external storage, the SSK is more versatile.
Sandisk WD_Black SN7100 1TB NVMe SSD
The WD_Black SN7100 is an internal M.2 2280 NVMe drive with Gen4 speeds and TLC NAND. It offers higher performance than the SSK for gaming and heavy workloads inside a computer. You gain faster load times and better endurance due to TLC memory. However, it lacks the external enclosure and USB connectivity of the SSK. It is Windows-only, limiting use with Macs or consoles. The SSK provides plug-and-play portability via USB-C. Choose the WD_Black if you are building a high-performance gaming PC or upgrading a laptop’s internal storage. Pick the SSK for external file transfers.
Addlink P21 1TB Portable External SSD
The Addlink P21 is a portable external SSD with 2,000MB/s read speeds, matching the SSK’s performance tier. It is lighter and designed for PS5 expansion and Mac compatibility. You get a compact form factor suitable for console storage or laptop backups. The SSK offers a thicker aluminum case for heat dissipation and includes an LED indicator. The Addlink focuses on cool running and broad device support. If you need to expand PS5 storage or want a lighter portable drive, the Addlink is practical. The SSK is better if you prefer a robust metal case and specific USB-C Gen2X2 connectivity.
GARMESE 1TB USB 3.2 Gen 2 Portable SSD
The GARMESE drive is a portable SSD with USB 3.2 Gen 2 connectivity, which is slower than the SSK’s Gen2X2 interface. It offers lower maximum speeds but includes USB-A compatibility for older computers. You gain wider device support for legacy ports. The SSK provides faster data transfer rates up to 2000 MB/s. The GARMESE is larger and heavier than the SSK. Choose this drive if you frequently connect to computers with only USB-A ports and do not need Gen2X2 speeds. The SSK is superior for users with modern USB-C ports who prioritize speed and a more compact design.
Intel 660p 1TB NVMe M.2 SSD
The Intel 660p is an internal M.2 NVMe SSD using QLC NAND. It is not a portable external drive like the SSK. You get a lower price point for internal storage upgrades in desktops or laptops. The SSK offers external portability and faster sustained speeds via USB 3.2 Gen2X2. The Intel drive lacks an enclosure and external interface. It is suitable for users upgrading internal storage capacity on a budget. The SSK is the better choice if you need to move files between devices, use OTG with mobile phones, or require external backup storage. Internal upgrades do not replace the need for portable drives.
