Recently, Silicon Power decided to refresh their M.2 PCIe 3.0 x4 SSD with a brand new model called XD80. The new SSD is available in capacities between 256GB up to 2TB. It also offers higher endurance and slightly better performance. I bet that you also noticed a heatsink with the XPower logo all this and much more we will show you in our review.

Let’s begin with specifications and features, while later, we will focus on the performance of the 2TB version of the XD80 M.2 SSD.

Speed Ahead Of The Competition

Featuring SLC Caching and DRAM Cache Buffer, the XD80 peels rubber with blazing read/write speeds up to 3,400/3,000MB/s, respectively. Its high-speed PCIe Gen3x4 interface leaves traditional SATA III SSDs behind in the dust, giving hardcore gamers the competitive edge they need to secure the win.

Eliminate Lag While Keeping It Cool

With NVMe 1.3 support, the XD80 delivers higher performance, lower latency, and lower power consumption for the smoothest gameplay without any lag. The durable aluminum heatsink provides maximum heat dissipation and thermal management. In fact, compared to SSDs without a heatsink, the XD80 keeps temperatures as much as 20% lower, maintaining its stability.

Better Performance With RAID Technology

In order to push beyond standard limits, the XD80 supports RAID technology and comes in massive storage capacity options up to 2TB. Even during the most highly demanding games, it will maintain the system stability and data integrity to deliver maximum and reliable performance.

Silicon Power decided to use 96-layer TLC NAND from Toshiba in the XD80 SSD. We had some good results on Toshiba NAND, so it’s a good sign. The XD80 SSD also uses the Phison PS5012-E12S-32 controller, which is getting popular in faster SSD series. The only surprise can be 512 MB of Xi’an UnilC DDR3-1866L DRAM. UnilC is a Chinese brand that is quite new on the memory market but already creates its own projects. So far, the XD80 SSD is the first product where I saw UnilC memory.

Below is a screenshot from the CrystalDiskInfo, which is showing that the SSD is in perfect condition.

Additionally, here is a screenshot from AIDA64, which is showing some more details about the drive. As we can see, the throttling point is set at above 70°C. As long as the SSD will have at least standard airflow, it shouldn’t throttle. During tests, the temperature was below 70°C, so if there was any throttling, then minimal and didn’t affect our results.

Let’s move to the next page to take a closer look at the package and the drive itself.

Package and its Contents

The XD80 SSD arrived in a retail package with a blister-type, transparent window so that we can see the product.

We will find the most important specifications on the package, like the drive’s interface, capacity, or warranty. The drive is covered by a five-year warranty that makes us happy as it’s above the average, and only high series storage products have such a long warranty. As we remember, the UD70 SSD also had a five-year warranty, so it’s getting a standard for Silicon Power products.

The XD80 is designed in a popular M.2 2280 format and works on the PCIe Gen 3 x4 bus. The declared maximum bandwidth is up to 3400MB/s. That’s about the maximum that PCIe 3.0 x4 socket can handle. In our tests, we could reach 3458MB/s, and it was repeatable, so I assume that this is the limit for our SSD, tested in a popular laptop.

Our tests were performed on the TUF A15 laptop from ASUS, which is slightly slower in storage tests than top desktop motherboards from the latest series. It doesn’t change the fact that we could achieve great scores on the XD80 SSD. On the next page, you can see our results.


As I already mentioned on this review’s previous page, the tests were performed on the ASUS TUF A15 laptop equipped with AMD Ryzen 7 4800H processor. This laptop is heating up above average but is also a realistic environment for an M.2 SSD, where is often limited airflow.

All tests were performed in Windows 10 Pro x64 with the latest updates.

Let’s begin with the ATTO Disk Benchmark, which is one of the most popular applications designed to measure storage bandwidth.

unnamed file 1957

ATTO is usually showing lower than expected maximum bandwidth, but we can still see up to 3.23GB/s read bandwidth, which is a good result for any PCIe 3.0 x4 SSD.

Much better results are in CrystalDiskMark. This is probably the most popular benchmark used to test SSD performance.

Our results are confirming that the XD80 has no problems reaching advertised read and write bandwidth. The maximum read bandwidth passed 3458MB/s, while the write bandwidth passed 3114MB/s. Worth mentioning are amazing random bandwidth results. The XD80 is about as fast in random operations as many popular M.2 PCIe 4.0 x4 SSD.

Another benchmark is PCMark 8 and its storage test. Even though not new, this benchmark shows how the drive performs during a daily workload, so various popular applications. Results in this benchmark are great for the PCIe 3.0 x4 SSD, and only PCIe 4.0 x4 SSD show significantly better bandwidth. For example, Silicon Power US70 could pass 600MB/s in this test, but the total benchmark score wasn’t much higher.

PCMark 10 storage tests are similar to what we could see in the PCMark 8 but base on newer applications and additional tests.

The XD80 2TB performs well in all these mixed-load tests. Even though it’s not PCIe 4.0 SSD, then its performance is high regardless of the test. The XD80 should satisfy all those users who have older motherboards or laptops as it’s significantly faster than older generation SSD and still uses PCIe 3.0 interface.

In the end, Anvil’s Storage Utilities. It’s a benchmark that usually shows lower bandwidth than expected, and it’s like that in this situation. Even though results are high, then we can see only up to 2.5GB/s read and write bandwidth. It’s about the same situation as in previous Silicon Power M.2 SSD reviews.

unnamed file 1961


The XD80 2TB SSD is for sure a great option for all those users who can’t use PCIe 4.0 SSD or don’t want to upgrade their hardware only because of the M.2 socket. The XD80 is a fast SSD which is great for any workload.

Conclusion and Verdict

The Silicon Power XD80 SSD offers a bit more than the UD70, which was already an excellent SSD. It’s slightly faster and offers higher endurance due to TLC NAND. Everything else is at about the same level so we can enjoy the same high quality of the SSD, the same problem-free installation, and the same long, five-year warranty.

In all our tests, the XD80 2TB SSD was performing well. There were no problems with stability or throttling. Especially random operations in benchmarks were high and actually higher than expected as this is the level of PCIe 4.0 SSD.

The Silicon Power XD80 2TB SSD is expected to cost about $240. It’s more than for the UD70 SSD but also less than many competitive 2TB TLC SSD costs. I think that the price isn’t high and gives a chance to be popular in the current storage market.



  • High performance
  • Easy to install and configure
  • Inexpensive
