2. Functions
- NVMe 1.3 Support: The SSD uses the NVMe protocol, which is optimized for communication between the SSD controller and the host processor. This enables faster data transfer compared to older AHCI protocols.
- PCIe Gen 3 x2: The SSD uses a PCIe 3.0 x2 interface, which offers twice as many data lines as PCIe x1, enabling better transfer rates and faster overall performance.
- 3D NAND Flash: The use of 3D NAND Flash technology provides better performance and higher storage density compared to older 2D NAND designs.
- Compatibility: The M.2 2280 form factor is standardized and fits many modern laptops and desktops that support M.2 slots.
3. Areas of application
- Laptops and Ultrabooks: The compact size and high performance make this SSD ideal for use in laptops and Ultrabooks where space and speed are important.
- Desktop PCs: Also suitable for desktop PCs, especially for systems that require an additional SSD or a fast SSD as a boot drive.
- System Upgrade: A good choice for upgrading older systems to improve operating system boot times and increase overall system performance.
- Compact systems: Due to the M.2 form factor and the lack of an external controller, the SSD is well suited for compact and slim computer cases.
4. Advantages
- Fast performance: With read and write speeds of up to 1,600 MB/s, the SSD offers significantly improved performance over traditional SATA hard drives and is faster than many older NVMe models.
- Compact size: The M.2 2280 form factor is small and allows the SSD to be used in slim and compact devices.
- Energy Efficiency: NVMe SSDs are generally more energy efficient than traditional SATA SSDs, which is especially beneficial for mobile devices.
5. Disadvantages
- Limited speeds compared to higher-end NVMe SSDs: While the SN520 offers good performance, there are faster NVMe SSDs on the market, particularly those that utilize PCIe Gen 3 x4 or PCIe Gen 4.
- Capacity: At 256GB, the capacity is limited and may not be enough for users who need to store large amounts of data.
6. Installation and Compatibility
- Installation: Installation is simple: The SSD is inserted into an M.2 2280 slot on the motherboard and fixed with a screw if necessary. The connection is made automatically via the PCIe bus.
- Compatibility: The SSD is compatible with many modern laptops and desktops that have a free M.2 2280 slot and support for NVMe. It is advisable to check the specifications of the system before purchasing.
