SanDisk 64GB microSDXC memory card Review

Here is the FoneArena review of the SanDisk 64GB microSDXC memory card that was launched recently in India. SanDisk doesn’t mention which class it belongs to, but after further investigation on some sites it is clear that it is a Class 6 Memory card. SanDisk promises read speeds up to 30 MB/sec. 

We tested this card on some phones including Motorola Razr and Samsung Galaxy S2 and even on a year old Sony Ericsson Xperia X10 and it works fine. Both the Razr and the Galaxy S2 comes with 16GB internal memory which makes the total space into 80GB to store all your Photos, Full HD videos and more. The Motorola Razr, Galaxy Note, Sony Tablet S and the Samsung Galaxy Tab 10.1 officially supports 64GB cards.

Let’s get into the detailed review and see how it performs on some benchmarks.

Read Write speed test using CrystalDiskMark

Read speeds were around 20 MB/s and Write speeds were around 9 MB/s.

Read Speed measured using HDTach

Read speeds were steady at 20 MB/s.

AnTuTu for Android Benchmark


Maximum Read speeds were around 27 MB/s and the Write speeds were around 19 MB/s with the Antutu app for Android. The speed varied drastically, and the increase in speed might be due to the app.

SD Tools for Android Benchmark

The Read speeds were around 22 MB/s and the Write speeds were around 6 MB/s with the SDTools app for Android.


We reviewed the SanDisk 32GB memory card last year but it was class 2 that was not that impressive. This 64GB Class 6 MicroSD card has impressive and steady write speeds and good read speeds. This is definitely great product for the amount of storage it offers and it costs around Rs. 14,799 in India. It is just incredible that Sandisk has managed to pack 64 GIGABYTES in such a tiny card.Wish the pricing was more enticing, it would be a good buy. But memory card prices are known to go down with time as newer versions arrive.But if you want to expand your phone’s inbuilt memory by another 64GB , the Sandisk 64GB microSDXC card is an easy answer if you don’t mind the price.
