Phidisk, a company that is from Penang, has a bunch of memory products in the market. The Phidisk PhantomKnight that we have here is an M.2-based SATA III SSD with 480GB of storage and controlled by a Phison S11 controller.

Being a budget SSD for day-to-day usage, let’s take a look at the performance to see if the PhantomKnight is on par with other budget SSDs in the market.

There is nothing particularly out of the ordinary for the packaging of the Phidisk PhantomKnight 480GB. I like how it just says M.2 2280 SATA III SSD with 480GB on the SSD sticker itself. However, the overall packaging seems to be a little dark, which camouflages the SSD with the background.

At the back is a very simplified specs list of the PhantomKnight SSD. Also, it comes with 5 years limited warranty.

There is literally nothing else in the box itself other than the M.2 SSD itself. That means a lot of excess cardboard which doesn’t serve any purpose. Even for force dampening, the box could’ve been smaller.

The M.2 SSD version is pretty much a direct translation from the 2.5-inch version that we reviewed here. Further inspecting the SSD’s PCB, we can find the Phison S11 controller here.

We also can see that this SSD utilizes NAND chips by Micron. There is no DRAM on the PhantomKnight SSD, which ultimately will affect its performance since there is no caching.

Synthetic Benchmarks


Developed by a Japanese coder that goes by the nickname Hiyohiyo, CrystalDiskMark is one of the most frequent used SSD Benchmark utility to measure SSD’s read and write performance.

AS SSD Benchmark

Widely used SSD benchmarking utility that uses incompressible data to simulate the worst possible scenario for an SSD and thus giving a much lower sequential read and write speed result than what has been stated by the manufacturer as a result of the heavy workload.

ATTO Disk Benchmark

The most frequently used benchmarking utility by many manufacturers for performance specifications. As ATTO Disk Benchmark uses compressible data rather than incompressible data, it results in higher benchmark scores.

File Transfer Speed Test

For this test, we’re using a collection of test data that consists of large and small files (both compressible and incompressible) total up to 36GB.

Overall, the Phidisk PhantomKnight 480GB is a pretty standard SSD in terms of performance. It is made to be a budget-oriented SSD, hence it did take a hit in the performance. The lack of DRAM affected its performance as the SSD is being filled to the brim. However, it is still perfectly fine for an average user’s day-to-day scenario, since this SSD is made for that market.

For the price of RM280, its performance is as expected. If you’re looking for a new SSD for your laptop or desktop, then take a look at this budget option.
