Need for Speed – A comprehensive review of the fastest microsd cards

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 notedCrystalDiskMark 5.0.2 x64 was used to produce all the test results and was set up with 2 passes and 100MB read/write sizeAll cards up to 32GB are formatted as FAT32 with 32KB allocation unit size, all 64GB cards are formatted exFAT with 128KB allocation unit sizeTest Results (Numbers are Sequential Read, Sequential Write, 4K Random Read, 4K Random Write in MB/s, speeds greater than 10MB/s were rounded to the whole numbers)16 GB AlphabeticallyLexar 633x** – 88, 25, 8.7, 1.2 <== the listed productPanasonic U3** – 93, 42, 11, 0.7Sandisk Extreme Pro – 95, 80, 7.6, 2.632 GB AlphabeticallyDelkin U3 – 93, 59, 11, 0.6Kingston 90R/80W – 93, 58, 11, 0.6Lexar 1000x – 90, 57, 10, 1.4Lexar 1000x with Bundled Reader* – 148, 60, 10, 1.4Patriot EP – 90, 35, 10, 0.6PNY Turbo Performance – 91, 55, 6.9, 0.9Samsung Pro gray – 92, 82, 10, 3.6Sandisk Extreme Pro – 94, 87, 9, 3.0Sony up to 95MB/s – 91, 51, 4.8, 0.9Transcend Ultimate 633x – 93, 85, 8.1, 1.464 GB AlphabeticallyDelkin U3 – 94, 27, 13, 0.3Kingston 90R/80W – 94, 25, 13, 0.3Lexar 1000x – 92, 56, 12, 1.5Lexar 1000x with Bundled Reader* – 153, 66, 11, 1.7Patriot EP – 81, 22, 11, 0.6PNY Turbo Performance – 92, 54, 6.9, 0.9Samsung black – 82, 20, 8.8, 2.1Samsung Pro gray – 90, 80, 10, 3.5Samsung Pro+ *** – 92, 86, 10, 5.3Sandisk Extreme Plus**** – 92, 58, 10, 2.8Sandisk Extreme Pro - 97, 91, 10, 3.0Sandisk Ultra ***** – 46, 16, 7.0, 2.1Sony up to 95MB/s – 92, 49, 5.2, 0.9Transcend Ultimate 633x – 93, 83, 7.3, 1.4128 GB AlphabeticallyLexar 633x – 78, 28, 3.3, 1.4 <== the listed productSandisk Ultra – 92, 19, 6.4, 2.4* The Lexar 1000x card is the only UHS-II card available and tested, the bundled USB reader has extra pins for reading UHS-II card** Came bundled with a device*** Purchased from a large west coast electronics retailer.

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 printLexar 1000x: White/Gold with Black/White printSamsung Pro+: White/Black with a red stripe and Black/White printPNY Turbo: Lime Green/Black with Black/White printUpdate 9/14/2015: Added additional cards to the list.

Good Value Card for Go Pro Black +

Did some research and narrowed my card search to the lexar. I took a gamble and ordered 2 sets. Upon receiving I did some validation tests by first formatting the card, and then zeroing it. I then used F3 for mac osx to benchmark the read/write speeds and to verify the capacity of the card.Using a macbook pro w/ the included usb 3.0 adapter my results were:CARD 1:write max: 38.02 MB/swrite avg: 37.86 MB/sread: 64.02 MB/sdata capacity: 29.81 GBzero corruptionsCARD 2:write max: 39.15 MB/swrite avg: 38.00 MB/sread: 63.95 MB/sdata capacity: 29.81 GBzero corruptionsConclusion… good value, solid performance, reliability remains to be seen. Will update if any issues arise.

don’t waste your money

after 6 months, it was dead suddenly. all of my records were disappeared.

like how my OCZ ARC100 only gets barely above 400MB/s

This is used for my Galaxy S5. Picture taking, movie saving, library transfers and just opening apps have been twice as fast. Editing hardly takes any time. I’ve never seen a faster memory card that was not a solid state drive. My original thoughts that “Up to” meant a hypothetical number that isn’t usually reached, like how my OCZ ARC100 only gets barely above 400MB/s. But this card, it barely scratches under the maximum transfer speeds. As far as mechanical hard drives go, this is 20MB/s faster read than my Western Digital Black 1tb.The only con would possibly be the price premium, but the performance is so much higher than the similarly priced Samsung EVOs (They’re only 45MB/S max, twice as slow!).In summary, the benchmark I provided should be enough to make you buy one, or two. :)

128GB Lexar 633x - stands up to its claims!

Great investment for Drones and GoPros.

This card is great for our 4K drone and allow us more autonomy and we don’t have to dump and back up the footage as often during the day.

I have recorded hours and hours of footage on several devices with this , mainly Go Pro White 3 and its still going strong. The adapter it came with has been incredible helpful.

Thumb Up

Initially buggy, failed completely after 2yr

I know these things have finite life. But i have had it in my gopro and my phone the last 2 years and it would lose and corrupt photos and videos from the very start.
