SANDISK Ultra 3D NAND 1TB Internal SSD - SATA III 6 Gb/s, 2.5 Inch /7 mm, Up to 560 MB/s - ‎SDSSDH3-1T00-G26

Bottom line: The SANDISK Ultra 3D NAND 1TB Internal SSD ($330.50 on Amazon as of 2026-10-21 10:26 UTC): Up to 560 MB/s read and 520 MB/s write, near the SATA III ceiling; main trade-off: SATA III caps it at 560 MB/s; NVMe drives run several times faster. Another in-stock pick with the same 1TB SATA: the Crucial MX500 1TB 3D NAND SATA 2.5 Inch Internal…, $380.65 on Amazon as of (price may vary).

Pros & Cons

Pros

  • ✓ Up to 560 MB/s read and 520 MB/s write, near the SATA III ceiling
  • ✓ 3D NAND raises endurance and reliability over older planar-NAND drives
  • ✓ nCache 2.0 caching keeps small-write bursts and app launches responsive
  • ✓ Shock-resistant with no moving parts, so a dropped laptop keeps its data

Cons

  • ✗ SATA III caps it at 560 MB/s; NVMe drives run several times faster
  • ✗ 7 mm 2.5-inch form factor won't fit M.2-only laptops and small-form desktops
  • ✗ Needs a SATA data cable and power lead, unlike a single-slot M.2 install
  • ✗ Speed claims come from SanDisk internal testing, not independent benchmarks

Manufacturer description

The SanDisk Ultra 3D 1TB internal SSD is a 2.5-inch SATA III drive built for upgrading an aging laptop or desktop that still boots from a mechanical hard drive. SanDisk rates it at sequential reads up to 560 MB/s and writes up to 520 MB/s over the 6 Gb/s SATA interface, which is close to the ceiling of what SATA allows, so you get the full jump a mechanical-to-solid-state swap can deliver. The 3D NAND inside is what makes the difference over older planar drives: greater endurance, better reliability, and lower power draw, which translates into longer battery life and cooler, quieter…

SpecPicks Verdict

SpecPicks scored SANDISK Ultra 3D NAND 1TB Internal SSD using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Compare with similarly-priced alternatives in the ssds & storage category before committing. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

How fast is the SanDisk Ultra 3D 1TB SSD?

SanDisk rates it at sequential reads up to 560 MB/s and writes up to 520 MB/s over SATA III 6 Gb/s, based on the company's internal testing. Real speeds vary with drive capacity, host device, OS, and application.

Will this SSD fit my laptop?

It is a 2.5-inch drive in a 7 mm z-height, so it fits standard 2.5-inch SATA bays in laptops and desktops. It will not fit machines that only accept M.2 drives. Check your system's drive bay type before ordering.

Is it faster than the hard drive already in my computer?

SanDisk compares it to a 7200 RPM SATA 2.5-inch hard drive and cites faster app loading, faster boot-up and shut-down, plus longer battery life and cooler, quieter operation, based on published specs and PCMark Vantage benchmarking.

What does nCache 2.0 and 3D NAND actually do?

3D NAND gives the drive greater endurance and reliability along with lower power usage than older flash. nCache 2.0 is a caching layer SanDisk credits for the drive's fast sustained speeds during everyday reads and writes.

How does it hold up if I drop my laptop?

The drive is shock-resistant and has no spinning platters or moving heads, so it is built to keep your data safe through a drop that would damage a mechanical hard drive. Check the product listing for current warranty terms.

Key Features

  • Sequential read/write speeds of up to 560MB/s/520MB/s (Based on internal testing; performance may vary depending upon drive capacity, host device, OS and application. 1 megabyte (MB) = 1,000,000 bytes.)
  • Faster app load and response times; faster boot-up and shut-down (As compared to 7200 RPM SATA 2.5” hard drive. Based on published specifications and internal benchmarking tests using PCMark Vantage scores.)
  • Greater drive endurance and reliability, plus lower power usage with new 3D NAND technology
  • nCache 2.0 technology delivers blazing-fast speeds
  • Shock-resistant to help keep your data safe—even if you drop your computer
