Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

Update: retested this on a PC running Windows 10. Previous test was done on an iMac and I mistakenly made the assumption that the test result on iMac would be comparable to test results posted by others using CrystalDiskMark. A sequential write speed of around 60MB/s was obtained on a PC, making it a significant improvement of write speed over the blue colored 633x card. I am updating the score to 5 stars.
Realizing that the benchmark results posted by other folks are not necessarily directly comparable to mine I set out to create a comprehensive list of current microSD cards on the market. The results are below.
---------------------------------------------------------------------------------------------
I had the opportunity to compare the performance of the fastest microsd cards currently available from top manufacturers. All cards mentioned in this review are obtained from Amazon during the last week or two except when noted otherwise.
Test Setup:
Lexar Professional workflow UR1 microsd card reader was used for all tests except when noted
CrystalDiskMark 5.0.2 x64 was used to produce all the test results and was set up with 2 passes and 100MB read/write size
All cards up to 32GB are formatted as FAT32 with 32KB allocation unit size, all 64GB cards are formatted exFAT with 128KB allocation unit size

Best overall:

Other observations:
Performance and price are not proportional when it comes to selecting a microSD card. Some of the worst performing cards in this review also happen to be the most expensive.
Not all 633x cards are created equal. The two cards reviewed from Lexar and Transcend are both marked as 633x but vary in performance greatly.
4k video recording using action cams and drone cameras have a typical bitrate of 60mbps or 100mbps, corresponding to 7.5MB/s to 12.5MB/s. All cards in this review should theoretically be able to handle this usage easily.
Using microsd card as supplemental phone storage potentially could benefit from a faster card,
Best Looking Card (if it matters):
Sandisk Extreme Pro: Red/Gold with white print
Lexar 1000x: White/Gold with Black/White print
Samsung Pro+: White/Black with a red stripe and Black/White print
PNY Turbo: Lime Green/Black with Black/White print

Update 9/21/2015: Added 2 PNY Elite Performance cards
**Lexar X1000 32G microSD card with bundled USB3.0 Reader:
Bundled USB3.0 reader: R/W/4kR/4kW 153/70/16/1.6 MB/s
PCIe SDHC reader: R/W/4kR/4kW 81/62/12/1.2 MB/s
USB2.0 SDHC reader: R/W/4kR/4kW 19/17/4.2/1.2 MB/s
Lexar X1000 32G microsd card has very fast read speed and pretty fast write speed. The USB3.0 reader can keep a constant write/read high speed, though it gets very hot while transferring full 32G data. I have used 3 kinds of flash drives from Samsung and SanDisk, all of them reduced speed to usb2.0 level after a few Gigabytes of data transfer. Recommend it to any one.
**Samsung EVO 32G microSD card:
Bundled USB3.0 reader: R/W/4kR/4kW 46/39/10/4.0 MB/s
PCIe SDHC reader: R/W/4kR/4kW 44/32/10/2.0 MB/s
USB2.0 SDHC reader: R/W/4kR/4kW 19/14/4/2.5 MB/s
For smart phones still using USB2.0 card reader, Samsung Evo is good choice for its good performance and cheap price. While Lexar X1000 can provide much faster download speed and pretty good writing speed.
The features I want in such a reader are:
- Very small size and only the one slot.
- USB 3 speed.
- Lanyard loop.
- Secure mounting of the microSD card with no risk of it falling out or being damaged while hanging from a lanyard or being kept in a pocket or backpack.
- Activity light.
This reader meets only the first three criteria. The card hangs part way out of the reader when fully inserted (see my photo), and while it is fairly secure in the slot, I do not feel that it is quite secure enough never to work its way out. (I use a small piece of adhesive tape on the top face of the reader that reaches around the back edge of the card to hold it in.) There is also no activity light.
Aside from that, I like it a lot. It is durable, attractive, and very fast, and has given me no trouble. There was one instance when I thought it had gone bad. I relate this story to help anyone else who encounters something similar with any device. A few days ago I inserted the reader into my computer's USB 2.0 port and the screen went dark and the computer became unresponsive and did not recover. I rebooted the computer and from then on the reader would not work properly in it. Windows 7 recognized that something had been plugged in, but the card's partition and data were not recognized. Computer Management would not even allow me to assign a drive letter to the device.
To cut the story short, the only problem was that the default Windows driver for the device had somehow gone corrupt. The device worked on all other computers and when I launched Device Manager, I found an "unrecognized storage device". I uninstalled the driver and then reinstalled it, and the reader has worked ever since. I have never seen this happen before.
So try reinstalling the driver (or using an alternate computer) before deciding that a device has gone bad.
