AI Verdict
A 1TB M.2 2280 PCIe Gen 4.0 SSD with 7,100 MB/s read speeds, suitable for general use and gaming, but utilizes QLC NAND.
This SSD offers 7,100 MB/s PCIe Gen 4.0 read speeds and a 5-year warranty, making it a strong contender for general computing and gaming. However, its QLC NAND and DRAM-less controller make it less suitable for sustained heavy write tasks like professional video editing, where endurance and consistent write performance are critical.
If you need more durability for heavy write cycles or guaranteed sustained write performance, look for SSDs with TLC NAND and a dedicated DRAM cache.

Pros
- Achieves sequential read speeds up to 7,100 MB/s.
- Backed by a 5-year limited warranty.
- Includes Acronis True Image software for data migration.
- M.2 2280 form factor ensures broad compatibility with modern desktops and laptops.
- Offers 600 TBW (Terabytes Written) endurance for the 1TB model.
- Designed for power efficiency, making it suitable for laptops.
Cons
- Uses QLC (Quad-Level Cell) NAND flash memory, which is less durable for heavy, sustained write activity compared to TLC.
- DRAM-less design relies on Host Memory Buffer (HMB), potentially impacting sustained write speeds in certain scenarios.
- Ships without an included heatsink or heat spreader.
- Does not support AES hardware-based encryption, adhering to the TCG Pyrite security standard.
Dimension Scores
The sequential read speed of 7,100 MB/s is fast for a PCIe Gen 4.0 drive, but the DRAM-less QLC design can affect sustained write performance.
It comes with a 5-year limited warranty and a 600 TBW endurance rating for the 1TB model, but QLC NAND is inherently less durable for heavy write cycles than TLC.
1TB is a practical and common capacity, providing ample space for operating systems, applications, and a significant game library for most users.
The M.2 2280 form factor and PCIe Gen 4.0 x4 interface are standard for modern desktop and laptop systems, ensuring broad compatibility.
Best For
- Everyday computing and general system responsiveness.
- Game libraries and faster game loading times.
- System boot drives for quicker startup.
- Laptops where power efficiency is a priority.
Not Recommended For
- Intensive, sustained video editing or other heavy write workloads.
- Users requiring AES hardware-based encryption for data security.
- Systems without adequate built-in thermal management for SSDs.
Watch Out For
- The QLC NAND flash memory means a potentially shorter lifespan if you're constantly writing large amounts of data to the drive.
- Its DRAM-less design can lead to inconsistent write performance during very large or sustained file transfers.
- You'll need to source a separate heatsink if your motherboard doesn't have one, as it ships without any thermal solution.
- It lacks AES hardware-based encryption, which might be a dealbreaker for some security-conscious users.

What Buyers Say
User feedback and expert reviews frequently highlight the drive's fast 7,100 MB/s read speeds for everyday tasks and gaming. However, the use of QLC NAND and a DRAM-less controller is a recurring point of discussion, with concerns about its long-term durability and performance during sustained heavy write operations. Many also note the absence of an included heatsink.
“Look, it's fast enough for my games and Windows, but if you're moving terabytes of video every day, that QLC and no heatsink would make me nervous, just saying.”
Common Praise
- Fast system boot times and application launches.
- Quick loading of game libraries.
- Power-efficient operation, making it suitable for laptops.
- Included Acronis True Image software simplifies data migration.
Common Complaints
- Concerns about the durability of QLC NAND for heavy, continuous write workloads.
- Potential for write speed degradation during sustained large file transfers due to the DRAM-less design.
- Does not come with a heatsink, requiring users to provide their own thermal solution.
- Lacks support for AES hardware-based encryption.
Ownership Tips
- You'll likely notice performance dips during very large, sustained file transfers due to the DRAM-less controller.
- For desktop use, you'll probably want to buy a separate heatsink to keep temperatures in check, especially under load.
- The included Acronis software actually makes migrating your old drive to this one pretty straightforward.
- It's surprisingly power-efficient, which is a plus if you're putting it in a laptop.
Frequently Asked Questions
Is this SSD suitable for a gaming PC?
Yes, it's suitable for game libraries and system drives, offering 7,100 MB/s read speeds for faster game loading and application launches.
Does it come with a heatsink?
No, the drive ships without an included heatsink or heat spreader, so you might need to purchase one separately for optimal thermal performance.
What is the warranty period?
It comes with a 5-year limited warranty from Sandisk.
Can I use this in a laptop?
Yes, its M.2 2280 form factor and power efficiency make it a suitable choice for upgrading storage in compatible laptops.
Does it include software for data migration?
Yes, it includes a download for Acronis True Image for Sandisk data migration software to help transfer your files.
Is it good for video editing?
While its read speeds are fast, the QLC NAND and DRAM-less design might lead to slower performance during sustained heavy write operations common in video editing.
Buying Guide
When you're looking at SSDs, you're balancing how fast it can read and write data, how much stuff it can hold, and how long it'll last. Faster speeds mean your computer feels snappier, but not all fast drives handle constant, heavy work the same way. The 'TBW' rating tells you roughly how much data you can write to the drive over its lifespan before it might start acting up.
Read/Write Speed
This is how quickly the drive can pull data off (read) or put data onto (write) itself. Think of it like how fast you can grab a book from a shelf (read) or put one back (write). Higher numbers mean less waiting for files to open or save, making your system feel more responsive.
NAND Type (QLC/TLC)
This refers to the type of memory cells used inside the SSD. QLC (Quad-Level Cell) stores more data per cell, which makes drives cheaper and allows for higher capacities, but it's generally less durable for repeated writes. TLC (Triple-Level Cell) stores less but is typically more robust for endurance. It's like having a larger, slightly less robust bookshelf versus a smaller, sturdier one.
DRAM Cache
A small, fast memory buffer on the SSD itself. It helps the drive manage data more efficiently, especially during sustained write operations. Drives without DRAM (DRAM-less) rely on your computer's main memory (Host Memory Buffer), which can be slower for heavy tasks. Imagine a librarian with a quick notepad (DRAM) versus one who has to remember everything (HMB).
Alternatives
If you need maximum durability for constant heavy writing or guaranteed sustained write speeds, look for PCIe Gen 4.0 NVMe SSDs that explicitly use TLC NAND and include a dedicated DRAM cache.
