⚡ PCIe 3.0 NVMe Performance

The drive uses:

• PCIe 3.0 x4 interface
• NVMe protocol

Typical advertised speeds for these models are around:

• 2000–3500 MB/s read
• 1500–3000 MB/s write depending on capacity and controller version.

PCIe 3.0 NVMe speeds generally fall in this range:
3500 MB/s3500\ \text{MB/s}3500 MB/s

For real-world usage, that means:

• Faster Windows boot times
• Quicker game loading
• Faster app launches
• Better file transfer speeds than SATA SSDs

Reddit users generally consider these speeds:

“Pretty standard nvme speed” for PCIe 3.0 drives.

💾 M.2 2280 Form Factor

The SSD uses:

• Standard M.2 2280 size

Meaning:
22mm×80mm22\text{mm}\times80\text{mm}22mm×80mm

This makes it compatible with many:

• Gaming laptops
• Desktop motherboards
• Mini PCs
• Small-form-factor systems

⚠️ Important:
Your system must support:

• NVMe PCIe M.2
  not just:
• SATA M.2

---

🔥 Thermal Performance

The drive typically ships:

• Without a heatsink

Under sustained heavy transfers:

• Thermal throttling may occur

For:

• Gaming PCs
• Workstations
• Long file transfers

a motherboard heatsink or aftermarket thermal pad is recommended.
