Options 1TB

  • Faster boot and app loads with sequential read up to 555 MBps
  • Quicker file saves and transfers with sequential write up to 520 MBps
  • 3D NAND technology gives higher endurance and lower power draw
  • nCache 2.0 buffer accelerates burst write performance
  • Shock-resistant solid-state design protects data if the laptop is dropped

Capacity and speed

The 1 TB drive delivers up to 555 MB/s sequential read and 520 MB/s sequential write over a SATA connection. That throughput is enough to accelerate operating-system boot, application launch and large-file transfers for everyday desktop or laptop workloads. Heavy sustained writes such as video rendering will eventually hit the SATA interface ceiling.

3D NAND and nCache 2.0

The drive uses 3D NAND flash paired with nCache 2.0 technology, which writes incoming data to a high-speed buffer before committing it to the main array. This architecture improves endurance and keeps performance consistent during mixed read/write activity. Lower power draw compared with mechanical drives also benefits laptop battery life.

2.5″ SATA integration

The standard 2.5″ form factor fits any drive bay or caddy that accepts a SATA III device, requiring only a data cable and a SATA power connector. No additional drivers are needed for modern operating systems. The solid-state design resists shock and vibration, protecting data if the system is moved or dropped.

Questions about this item

Will the SanDisk Ultra 3D SDSSDH3-1T00-G26 fit a laptop bay that uses the 2.5" form factor?

Yes, the drive uses the 2.5" form factor and connects via SATA III, so it fits standard 2.5" SATA drive bays found in many older laptops and desktops.

How can I verify the SanDisk Ultra 3D SDSSDH3-1T00-G26 is performing at its rated 555 MBps read and 520 MBps write speeds?

Run a benchmark tool such as CrystalDiskMark on a SATA III port; sequential results should approach 555 MBps read and 520 MBps write for the 1 TB model.

What is included with the SanDisk Ultra 3D SDSSDH3-1T00-G26 and what must I supply myself?

The drive itself is included; a SATA data cable, mounting screws and any cloning software must be sourced separately.
