AI Verdict
A 1TB PCIe Gen 3.0 NVMe SSD with up to 3,200 MB/s read, best for secondary storage where sustained large file transfers aren't critical.
This 1TB PCIe Gen 3.0 NVMe SSD offers quick boot and application load times for everyday use, but its DRAM-less design means it struggles with sustained large file transfers. It's a fit if your workload involves mostly reads and smaller writes.
If you need consistent high write speeds for large files, look for an NVMe SSD with a DRAM cache and potentially PCIe Gen 4.0 interface.

Pros
- Sequential read speeds reach up to 3,200 MB/s, which is 5x faster than SATA drives.
- Offers 1TB of storage capacity for photos, videos, music, and documents.
- Installs easily with a one-screw application in M.2 2280 slots in many desktops and laptops.
- Includes access to Western Digital Dashboard for drive health reports.
- Operates at a cool temperature during intensive tasks.
Cons
- Lacks DRAM, leading to significant performance drops during large file transfers.
- Sequential write speeds are up to 2,500 MB/s, lower than its read speed.
- Users report performance dropping to 300 MB/s or even 2 MB/s when copying large files.
- Does not include an installation screw, requiring a separate purchase.
- Limited 3-year warranty, shorter than some competitors.
Dimension Scores
Offers up to 3,200 MB/s sequential read, which is above SATA speeds, but sequential write is lower at 2,500 MB/s and drops severely during sustained transfers due to lacking DRAM.
Backed by a 3-year warranty and a 100TBW endurance rating, which is standard for a 1TB drive, but some users report performance inconsistencies.
1TB capacity is ample for a secondary game drive or general storage, fitting many users' needs without being excessive.
The M.2 2280 form factor and PCIe Gen 3.0 interface ensure broad compatibility with most modern desktops and laptops.
Best For
- Expanding storage for games and applications on a desktop or laptop.
- Boot drive for light-use systems not handling large, frequent writes.
- Secondary drive for documents, photos, and music storage.
Not Recommended For
- Primary drive for content creation or video editing workstations.
- Users who frequently transfer large files (e.g., 30GB+ files) between drives.
- High-performance gaming rigs demanding consistent peak speeds.
Watch Out For
- Performance drops significantly during sustained writes; one user reported speeds as low as 2 MB/s when copying a large file.
- The drive is DRAM-less, which means its write speed will tank after its SLC cache fills up, typically around 30GB of continuous writing.
- No mounting screw is included in the package, so you'll need to source one yourself for installation.

What Buyers Say
Users frequently point out that while this drive is fast for everyday tasks and initial loads, its performance takes a nosedive when trying to move large files. Multiple reports on Reddit detail write speeds plummeting to 300 MB/s or even 2 MB/s after just a few gigabytes, which is a direct consequence of its DRAM-less design. It's often seen as a budget-friendly option, but that comes with a clear trade-off in sustained write performance. Installation is generally straightforward, though you'll likely need to find your own mounting screw.
“Man, this thing is fast for booting up Windows and my games, but when I tried to copy my 50GB video project, it just crawled to a halt after like 30GB, seriously annoying.”
Common Praise
- Applications and the operating system load noticeably quicker than with older drives.
- Installation is simple and quick, fitting easily into M.2 2280 slots.
- Provides a significant speed upgrade over traditional SATA SSDs.
- Maintains a cool operating temperature even during use.
- Offers good value for its capacity if sustained writes aren't a concern.
Common Complaints
- Write speeds drop dramatically when transferring large files, making it frustrating for big data moves.
- The absence of a DRAM cache impacts performance, especially for heavy multitasking or OS drive use.
- Does not include an M.2 mounting screw, which is an annoying oversight.
- Some users experienced performance issues even after SanDisk replaced the drive, suggesting a design limitation.
Ownership Tips
- After a few weeks, you'll notice that while games load fast, installing new ones or moving large folders feels slower than expected.
- The Western Digital Dashboard software is actually useful for checking drive health and firmware updates.
- If you're constantly moving big files, you'll quickly hit the performance wall of its DRAM-less design.
- It runs cool, so you probably won't need an aftermarket heatsink unless your case airflow is terrible.
Frequently Asked Questions
Is this SSD suitable as a primary drive for my operating system?
It can function as an OS drive for general use, but some users advise against it due to its DRAM-less nature, which can cause slowdowns during system updates or large application installations.
What kind of performance can I expect for gaming?
For loading games, you'll see faster times compared to SATA SSDs. However, if games involve frequent, large background writes or asset streaming, the DRAM-less design might cause occasional stutters.
Does this SSD come with a heatsink?
No, this specific model does not include a heatsink. While it generally maintains a cool operating temperature, consider adding one if your system has poor airflow or if you anticipate heavy, sustained workloads.
How does its speed compare to a traditional SATA SSD?
It's significantly faster, offering up to 3,200 MB/s sequential read speeds, which is up to 5 times quicker than typical SATA SSDs.
What is the warranty period for this drive?
The SanDisk 1TB SSD Plus M.2 NVMe SSD comes with a 3-year limited warranty.
Can I use this in both a desktop and a laptop?
Yes, its M.2 2280 form factor and PCIe interface make it compatible with many desktops and laptops that have a corresponding M.2 slot.
Buying Guide
When you're looking at an SSD like this, you need to think about what you're actually doing with it. The 'up to' speeds are for quick bursts, like opening programs. If you're constantly moving huge files, like 4K video projects or massive game libraries, those advertised speeds won't last. Pay attention to whether it has DRAM, because that's what keeps speeds consistent during long transfers.
PCIe Gen 3.0
This is the connection type. Think of it like a highway for your data. Gen 3.0 is like a three-lane highway; it's fast, but Gen 4.0 is a four-lane highway, even faster. For most everyday tasks, Gen 3.0 is plenty quick.
NVMe
This is the protocol, or the rules of the road, for how data travels on that PCIe highway. It's much more efficient than older SATA protocols, allowing for much higher speeds and lower latency, like a direct express lane.
DRAM-less
DRAM is like a scratchpad for the SSD controller to manage data. Without it, the drive has to use a slower method (Host Memory Buffer or HMB), which works fine for small tasks but gets bogged down when you're writing a lot of data continuously, like trying to juggle too many things without enough hands.
Alternatives
If you need consistent high write performance for large files, search for NVMe SSDs with a dedicated DRAM cache and potentially a PCIe Gen 4.0 interface for future-proofing.
