Who it fits

Ediloca EN855 Key Specs Explained

Interface: PCIe Gen4 x4 NVMe 1.4

This interface defines how the drive connects to your system. It uses four data lanes for high bandwidth, supporting the NVMe 1.4 protocol. You get faster data transfer than older SATA or PCIe Gen3 drives. This ensures your CPU spends less time waiting for data, improving overall system responsiveness during heavy workloads or game loading.

Max Read Speed: 7,400MB/s

This number shows how fast the drive retrieves data from storage. At 7,400MB/s, it approaches the limit of current PCIe Gen4 controllers. You will see quicker boot times and faster asset loading in games. This speed is significantly higher than SATA SSDs, which cap around 550MB/s, making it ideal for high-performance PCs and PS5 consoles.

Max Write Speed: 5,200MB/s

Write speed measures how quickly you save files or install games. 5,200MB/s is a strong performance tier for Gen4 drives. You benefit from reduced wait times when copying large video files or installing massive game updates. While lower than read speeds, this rate still far exceeds SATA capabilities, ensuring smooth operation during sustained data transfers.

Cache Type: 1GB DRAM, Dynamic SLC Cache

The 1GB DRAM cache acts as a map for your data, helping the drive manage information efficiently. This reduces latency and improves consistent performance. The dynamic SLC cache temporarily speeds up writes by storing data in a faster mode. Together, these technologies prevent stuttering during large file transfers, keeping your system stable under load.

Cooling: Aluminum Heatsink

This component dissipates heat generated during high-speed operations. Thermal throttling slows down drives when they get too hot. The aluminum heatsink helps maintain stable speeds during long gaming sessions or heavy workloads. You avoid performance drops caused by overheating, which is crucial for compact builds or PS5 slots where airflow might be restricted.

Design and Build Quality

According to the listing, this drive uses a compact M.2 2280 form factor. This standard size allows it to fit into most modern laptops, desktops, and the specific expansion slot in the PlayStation 5. The black finish is purely aesthetic, but the physical layout includes an integrated aluminum heatsink. This metal cover is not just for looks. It acts as a thermal bridge to draw heat away from the internal NAND and controller during heavy workloads. This design choice helps prevent thermal throttling, which can slow down speeds when the drive gets too hot. You do not need to buy a separate cooler for your PS5 or many desktop builds.

The package includes installation screws and a screwdriver, which simplifies the physical setup. You simply slide the drive into the slot and secure it with the provided hardware. There are no external controls, buttons, or displays on the unit. The design is entirely internal and passive. The aluminum heatsink covers the top surface, leaving the bottom accessible for connection to your motherboard or console. This straightforward build means you can install it in tight spaces without worrying about bulky custom cooling solutions. The materials listed suggest a focus on durability and heat management rather than flashy aesthetics. It is a practical, utilitarian design meant to stay hidden inside your system while maintaining performance under load.

Setup and Everyday Use Guide

Installation is straightforward thanks to the M.2 2280 form factor. The drive fits into standard slots in laptops, desktops, and the PlayStation 5 expansion bay. Ediloca includes the necessary screws and a screwdriver to secure the unit. You do not need additional tools to complete the physical installation.

The included aluminum heatsink plays a key role in daily operation. It attaches to the drive to dissipate heat. This cooling solution helps prevent thermal throttling during intensive tasks. By maintaining lower temperatures, the drive sustains its peak read and write speeds. This is particularly useful for long gaming sessions or heavy data transfers in compact PC cases.

For users, the 1GB DRAM cache improves system responsiveness. It manages data mapping efficiently, which reduces latency during random read and write operations. This makes the drive suitable for running operating systems and multiple applications simultaneously. The dynamic SLC cache further boosts performance for burst workloads.

Compatibility extends beyond just gaming consoles. The PCIe Gen4 x4 interface ensures broad support for modern motherboards. You can use this SSD in PS5 slim models or high-performance desktops. The plug-and-play nature means you can upgrade storage without complex configuration. Once installed, the drive operates silently and reliably, providing fast access to your files and games without interrupting your workflow.

Before You Buy This SSD

You should verify your motherboard supports PCIe Gen4 x4 to access the full 7,400MB/s read speeds. If your system only handles Gen3, you will still use the drive but at lower bandwidth. For PS5 owners, this M.2 2280 model fits the expansion slot perfectly. The included aluminum heatsink helps manage thermal throttling during long gaming sessions, but you must ensure your case has adequate airflow. The drive uses 3D TLC NAND with a 1GB DRAM cache, which improves sustained performance over large file transfers. You may need additional storage for large game libraries, as the 1TB capacity fills quickly with modern titles. This unit sits alongside other high-speed NVMe options in our 1 guide. It suits users who prioritize low latency and fast load times. Those needing massive bulk storage might consider the 4TB variation instead.

Check before you buy

• Confirm your motherboard supports PCIe Gen4 x4 interface
• Check PS5 expansion slot clearance for the heatsink
• Verify M.2 2280 form factor fits your device
• Ensure adequate case airflow for thermal management
