Key Features

PCIe 4.0 NVMe Performance

Built on the PCIe Gen4 x4 interface with NVMe 1.4 technology, the S770 offers:

• Sequential read speeds up to 7,300–7,400 MB/s
• Sequential write speeds up to 6,800 MB/s (capacity-dependent)
• Faster operating system boot times
• Near-instant application launches
• Rapid game loading and large file transfers

The drive is also backward compatible with PCIe Gen3 systems, operating at Gen3 speeds when installed in older motherboards.

Dedicated DRAM Cache

Unlike many budget NVMe SSDs that rely on Host Memory Buffer (HMB), the S770 includes dedicated DRAM cache, which provides:

• Faster sustained write performance
• Improved multitasking
• Reduced latency
• Better performance during large file transfers
• More consistent speed under heavy workloads

 

Premium 3D TLC NAND Flash

The S770 uses 3D TLC NAND, offering better endurance and sustained performance than many entry-level QLC SSDs.

Benefits include:

• Higher durability
• Consistent long-term performance
• Better write endurance
• Reliable everyday operation

PS5 Ready

The S770 meets the storage performance requirements for PlayStation 5 expansion.

Features include:

• M.2 2280 form factor
• PCIe Gen4 interface
• High-speed game loading
• Optional heatsink versions available (or use a compatible PS5 heatsink)

 

Available Capacities

• 1TB – Ideal for operating systems, applications, and a moderate game library.
• 2TB – Excellent balance of speed and storage for gamers and creators.
• 4TB – Designed for extensive game collections, 4K/8K video editing, and professional workloads.
