Reviewed: Lexar High-Performance UHS-I 633x MicroSD (64GB)

Lexar High-Performance UHS-I 633x MicroSD Retail FrontToday, we will start looking at the higher end spectrum of microSD cards, which costs above SGD$50. Here, we have with us the Lexar High-Performance UHS-I 633x MicroSD card, which is Lexar’s highest end offering of the memory cards. This, on the heels of their mid-range offerings of the 300x, so how will this fare?

The Lexar High-Performance UHS-I 633x MicroSD is rated to be up to 95MB/s and comes in the black and blue colour design. On the front, we can see that it is being marketed for use for sports/mobile so we are expecting a good sequential and random speeds.

Unlike normal cards, this card comes with a USB3.0 microSD card reader. Similar to one provided on the older variant of the Lexar High-Performance UHS-I MicroSD [300x], only this series now comes with the card reader.

On the reverse, we can see the FCC, CE certification, together with the model, serial/batch of the card. In addition, its origin is also on the card, and without any surprise, it is made in Korea. Something that makes this different is also the fact that it is matte, whilst other cards have it in gloss.

As seen earlier, the card is rated UHS-I and class 10 rated which tells us we can expect a minimum performance of 10MB/s for read and write speed.

So now, how does this match up to the mid-range Lexar High-Performance UHS-I MicroSD [300x] series? Let us take a look now!

Our first test here is the h2testw:

The speed on the h2testw was pretty consistent and constant for both read and write.

Next, we will run the CrystalDiskMark in various capacities. The first capacity we run it on was 4000MB or 4GB. The result can be seen below:

The next test, we ran the smallest test – 50MB:
Lexar High-Performance UHS-I 633x MicroSD CrystalDiskMark 2

And finally, we run the middle sized test, taking the average of 5 attempts:

When compiled into a graph:

Lexar High-Performance UHS-I 633x MicroSD Random Read graph

Overall, as we can see, the card has a rather consistent performance in write in the graph, although the read was not as constant we hoped it would be. In the speedwise, it has one of the fastest read results. Overall, the speed are:

READ – 81257 KB/s
WRITE – 44680 KB/s

As mentioned, the card comes with a microSD USB3.0 adapter, so let us put this to the test as well!

Nonetheless, it was nice to see that a USB3.0 card reader was included in the package, although, of course it was not performing as well as the larger counterparts.

All in all, this card still meets the UHS-I Class 3 specification although it is only officially rated to Class 1. Whilst the random performance has out-shined that of the 300x series, the card still performs slower than the other cards, such as the Samsung Plus and Samsung EVO. As such, whilst it can be highly recommend for use for sports or videography, as well as filming in 4K, usage for this in mobile, its perhaps not exactly worth the price.

Powered with MLC NAND at the heart of it, and with a availability price of about SGD$90, I won’t say that this is the best for mobile. It sure does not hold the fastest write speed, but it sure does have the fastest read speed.

Rating: ★★★★★★★½☆☆
