Internal SSDs

Fast and durable, internal solid state drives (SSDs) can help you quickly access your data, whether you’re working, gaming, or streaming content. 

What is an internal solid state drive? 

Internal SSDs use NAND — a kind of flash memory — to store your data, deliver on speed, and drive performance. When comparing SSDs to HDDs (hard disk drives), you can count on internal SSDs to:   

  • Load faster with less lag  
  • Be lightweight and more efficient  
  • Be durable — resistant to drops and bumps  
  • Run cooler and quieter 

Use an internal SSD for everything from creating and sharing photos to pro-level gaming and multi-tasking. Learn more about choosing between an SSD and HDD

Internal SSDs vs. External SSDs

Wondering what the difference is between internal SSDs vs. external SSDs?

Internal SSDs connect to your computer with a SATA (Serial Advanced Technology Attachment) or PCIe® (Peripheral Component Interconnect Express) connection.

External SSDs are portable devices that can be plugged into your computer via outside ports. Because they use SATA or PCIe, internal SSDs are faster than external SSDs.  

NVMe vs. SATA 

If you’re shopping for the fastest internal SSD, choose NVMe™ (Non-Volatile Memory Express) vs. SATA. NVMe, which connects to your laptop or desktop PC via the PCIe® interface, can hit speeds as high as 7.5GB per second1. Compare this to SATA, which typically tops out at 500MB per second.   


A communications protocol optimized to handle high bandwidth SATA transfer, with up to 4 lanes per device. Supports up to 1000MB/s per lane with PCIe interface.
