The Transcend 120GB MTS420S M.2 SATA SSD delivers reliable performance in a compact 2242 form factor. It uses SATA III 6GB/s interface speeds with SLC caching for consistent data handling. This drive suits users with space-constrained devices who need standard SATA compatibility. However, you might look for transcend 120gb mts420s m 2 sata alternatives if your system requires a different physical size or higher capacity. Some devices only accept the longer 2280 M.2 modules, while others may need the traditional 2.5-inch SATA connection. You may also prefer more storage for your operating system and applications.

The alternatives listed here were chosen because their specifications overlap with the original drive’s core features. Each option maintains SATA III connectivity and includes SLC cache technology for improved write performance. You can find M.2 2280 drives for standard laptops, or 2.5-inch models for desktops and consoles. These selections cover various storage capacities, ranging from 120GB to 512GB. This allows you to match the drive to your specific hardware constraints and storage needs without compromising on the essential SATA interface performance you expect.

Our top pick: Transcend 120GB M.2 2242 SATA SSD.

Comparing these SATA SSD options

Timetec 256GB M.2 SATA III SSD

The Timetec 256GB M.2 SATA SSD uses the standard M.2 2280 form factor, making it incompatible with the Transcend’s 2242 slot. You gain double the storage capacity and a larger physical footprint. It relies on 3D NAND with SLC caching for consistent performance. This drive is designed for standard laptop upgrades where space allows for the longer 80mm length. If your device supports the 2280 size, you get more room for data without sacrificing SATA III reliability. The trade-off is the physical size difference, which matters only if your chassis requires the compact 42mm profile.

TEAMGROUP T-Force Vulcan Z 256GB SATA SSD

The TEAMGROUP T-Force Vulcan Z is a 2.5-inch drive, which is physically much larger than the Transcend M.2 unit. It offers 256GB of storage, providing more capacity than the 120GB model. You must use a SATA data cable and power connector rather than a direct motherboard slot. It uses 3D TLC NAND with SLC caching. This option suits desktops or laptops with standard drive bays. You sacrifice the compactness and direct slot integration of the M.2 2242 form factor for a familiar, versatile drive that works in almost any system with a SATA port.

Fikwot 256GB M.2 2280 SATA SSD

The Fikwot 256GB M.2 SATA SSD also uses the M.2 2280 form factor, so it does not fit the Transcend’s 2242 slot. You receive twice the storage capacity for your system. It utilizes 3D TLC NAND with SLC caching to manage data efficiently. This drive is intended for standard M.2 slots in laptops or mini PCs. The primary difference is the physical length and capacity. If your device supports the 2280 size, you get more storage space. However, you cannot use this drive in systems that strictly require the shorter 2242 form factor found in the original Transcend model.

Transcend 120GB M.2 SATA SSD

The second Transcend model is a 120GB M.2 SATA SSD, matching the storage capacity of the original. However, it uses the M.2 2280 form factor instead of 2242. This means it is longer and will not fit in the same slot. It retains the SATA III interface and SLC caching for similar performance characteristics. You choose this alternative if your device supports the standard 2280 length but you need the same 120GB capacity. The key difference is physical dimensions. You gain compatibility with standard slots but lose the ability to install it in compact 2242 spaces.

Addlink S20 512GB 2.5-Inch SATA SSD

The Addlink S20 is a 512GB 2.5-inch SATA SSD, which is significantly larger than the Transcend M.2 drive. You get more than four times the storage capacity. It uses 3D NAND with SLC caching for reliable data handling. This drive requires a SATA data cable and power connection, unlike the direct slot integration of the M.2 model. It is ideal for PS4s or desktops with standard drive bays. You trade the compact, slot-mounted design for substantial storage space and versatility. This option is best if you have available drive bays and need more capacity than the original provides.

Silicon Power A55 128GB M.2 SATA SSD

The Silicon Power A55 is a 128GB M.2 SATA SSD, offering slightly more capacity than the Transcend 120GB model. It uses the M.2 2280 form factor, so it is not compatible with the 2242 slot. It features SLC caching and a SATA III interface for consistent performance. This drive fits in standard M.2 slots in ultrabooks and mini PCs. You gain a small amount of extra storage and compatibility with standard slots. The trade-off is the inability to use it in devices requiring the shorter 2242 form factor. It is a good alternative if your system supports the longer 2280 size.

Frequently asked questions

Can I use a 2280 SSD in a 2242 slot?

No, you cannot. The M.2 2242 form factor is physically shorter than the standard 2280 size. A 2280 drive will not fit into a slot designed for the smaller 2242 module. You must choose a drive that matches your specific slot length, such as the Transcend 120GB M.2 2242 SSD or the Silicon Power A55 128GB M.2 SATA SSD.

What is the largest capacity available for M.2 2242 SATA drives?

The largest capacity listed for this specific form factor is 120GB. Both the Transcend 120GB M.2 2242 and the 2280 variants offer this same storage size. If you need more space, you must switch to a different form factor. The Timetec and TEAMGROUP options provide 256GB or more, but they use larger 2280 or 2.5-inch sizes.

Do these drives include DRAM cache?

No, none of the listed products include DRAM cache. They all rely on SLC caching to manage data writes. This approach helps maintain consistent performance for everyday tasks without the added cost or power draw of a separate DRAM chip. It is a common configuration for budget-friendly SATA SSDs that prioritize value and reliability over maximum sustained write speeds.

Which alternative is best for a standard laptop upgrade?

The Timetec 256GB M.2 SATA SSD is the top choice for standard laptops. It uses the M.2 2280 form factor, which is the standard size for most modern and older laptops. It offers 256GB of storage and uses 3D NAND with SLC caching. This provides a good balance of capacity and endurance for typical computing needs compared to the smaller 120GB options.

Can I use a 2.5-inch SATA SSD in an M.2 slot?

No, you cannot. The 2.5-inch form factor is physically incompatible with M.2 slots. Drives like the TEAMGROUP T-Force Vulcan Z and Addlink S20 are designed for standard drive bays in desktops or older laptops. You need an M.2 drive if your device only has an M.2 slot. The Transcend 120GB M.2 2242 SSD fits those specific compact slots.

Is the Fikwot drive a good budget option for M.2 2280?

Yes, the Fikwot 256GB M.2 SATA SSD is a strong budget choice. It uses the standard M.2 2280 form factor and offers 256GB of storage. It features 3D TLC NAND with SLC caching for reliable performance. This drive suits users upgrading older laptops or mini PCs who want more capacity than the 120GB Transcend models without paying for premium features.

What NAND type do these SSDs use?

Most listed drives use 3D NAND. The Timetec, TEAMGROUP, Fikwot, and Addlink models specifically mention 3D NAND technology. The Transcend models do not specify the NAND type in the provided data. 3D NAND stacks memory cells vertically, which generally improves density and endurance compared to older planar NAND designs, making it a standard for modern SATA SSDs.
