SPECIFICATIONS

The Fanxiang S770 is a premium-oriented:

• PCIe 4.0 x4 NVMe SSD
• M.2 2280 internal SSD
• Available in:
  • 1TB
  • 2TB
  • 4TB capacities

It is designed for:

• PS5 storage expansion
• Gaming desktops
• High-performance laptops
• Content creation
• Large game libraries

Advertised speeds reach:

• Up to 7300 MB/s read
• Up to 6800 MB/s write depending on capacity.

---

⚡ PCIe 4.0 Performance

The S770 uses:

• PCIe Gen4 x4 interface
• NVMe protocol

Peak Gen4 consumer SSD speeds are around:
7300 MB/s7300\ \text{MB/s}7300 MB/s

That makes it dramatically faster than:

• SATA SSDs
• Older PCIe 3.0 SSDs

Real-world benefits include:

• Faster game loading
• Reduced texture streaming delays
• Large file transfer acceleration
• Better workstation responsiveness

ServeTheHome testing found the S770:

“in a functional tie for the top”
among Gen4 SSD benchmark results.

---

🧠 DRAM Cache Advantage

One major advantage of the S770:

• Dedicated DRAM cache

Unlike many cheaper Gen4 SSDs that use:

• DRAM-less HMB designs

The S770 includes:

• DDR4 DRAM cache.

Benefits include:

• Better sustained write speeds
• Improved multitasking
• More consistent heavy-load performance
• Better handling of large game installs and content creation workloads

---

💾 TLC NAND & Controller

The drive commonly uses:

• Innogrit IG5236 controller
• YMTC 128-layer TLC NAND.

This same controller appears in several:

• Higher-end Gen4 SSDs

The TLC NAND is preferable to QLC because it generally offers:

• Better endurance
• Better sustained speed consistency
• Longer write lifespan

---

🎮 PS5 Compatibility

The S770 is specifically marketed for:

• PlayStation 5 storage upgrades

Sony recommends PS5 SSDs capable of around:
5500 MB/s5500\ \text{MB/s}5500 MB/s

The S770 exceeds that requirement comfortably.

Many versions also include:

• Heatsink kits
• Thermal pads
• Installation screws

which are useful for PS5 installation.

---

🔥 Thermal Performance

High-speed Gen4 SSDs generate substantial heat.

The S770 often includes:

• Optional heatsink
• Thermal pads
• Mounting accessories.

This is important because:

• Gen4 drives can thermal throttle under sustained load

For:

• PS5
• Gaming PCs
• Workstations

good airflow or heatsink use is recommended.

---

🖥️ Real-World Usage

The S770 is well suited for:

• AAA gaming
• PS5 expansion
• Video editing
• Large file workflows
• Game recording/editing
• High-speed boot drives

The 4TB model is especially attractive for:

• Massive Steam libraries
• Media storage
• Creator workstations
