This review is from: Samsung 32GB Class 10 Micro SDHC Card Essential Class Card (Accessory)
PLEASE NOTE: This review refers to the Samsung _32 GB_ Micro SDHC MB-MSBGAEU _bought directly from AMAZON UK_, and not to any other smaller or different Samsung card sold by any other marketplace seller or even on Amazon. It is important to understand that there are LOTS of fake cards on the market, which might be defective, and other Samsung cards with smaller sizes or different models, which might have completely different performances, so beware what you are buying…!
First things first: as I wrote in my review of a Transcend 8 GB Class 10 SDHC card, I have always been wary of extremely large flash memories, for obvious reasons: unreliability (documented by many Amazon reviewers around the world…), high failure rate, and the extremely likely danger of losing huge amounts of precious data _all at once_, especially when these cards are used for long, sustained data transfers that might raise their temperatures too much…
Moreover, the very high cost of high-capacity, Class 10 Micro SDHC cards _so far_ in my opinion made their purchase not convenient at all…
Nevertheless, in the last year the price of these memories has dropped so much, and their performance and reliability have improved at such a level, that I decided to take the plunge and risk my hard-earned money on this one, since I had decided to transfer my entire, huge collection of thousands on MP3, picture and video files on my Samsung S8500 phone (IMHO a perfect portable multimedia platform to enjoy all such contents).
I chose this specific card not only for obvious compatibility reasons with my phone, but also because Samsung is among the top producers of solid-state memories in the world, and has a proved record of high performance, reliable memories.
Moreover, this is a new product that was supposedly _designed_ to match the features of recent phones, tablets, etc.: it is magnet proof (so no harmful magnetic interference inside the devices), shock proof (so no danger of losing data due to falls, in theory) and even water proof (I hope I will never have to verify that…), and it should provide adequate performances, including a _decent read/write speed with small files_, which is extremely important on such devices, especially if you install system programs/files on the external card instead of the built-in memory, as I do.
So, if you want to know right now how this card behaved in a typical PC benchmark, I tried to use one on the empty card after formatting it on my phone, and I immediately obtained _great_ results, even while using the system, browsing Internet, moving the mouse, etc.: as a matter of fact, the typical test methodologies often assume the absence of any cuncurrent operations, perfectly “clean” systems that _nobody would use_ in the real world, “safe” operations that no real user would probably be able to apply day-to-day, etc., while I always apply a _realistic_ average-user behaviour, instead…
WRITING SPEED (MUCH more important than read speed, since it is the writing speed that can be the real bottleneck of any device, either when you write system files on the card, or if you have to index lots of files, or if you simply want to record movies, music, pictures, etc. on it.)
Approx. 8-10 MB/sec. with files within 7-32 MB sizes (very good, between nominal Class 8 and actual Class 10) Approx. 4.7 MB/sec. with 256-KB files (again, pretty decent for a card of this class and especially at this very low price…) Approx. “ONLY” 1 MB/sec. with 32-KB files (BEWARE: this might slow down some systems, but it is quite normal on huge cards with higher classes, since these cards are specifically engineered to provide high speeds _only with larger files_, while smaller cards with lower classes (4 to 6) behave much better with smaller files.
READING SPEEDS These were really great, IMHO! (And basically matched what was promised by the manufacturer):
Approx. 20 MB/sec. with files of 64 MB size Approx. 10 MB/sec. with files of 7 MB size Approx. 16 MB/sec. with files of 256 KB size Approx. 6.7 MB/sec. with files of 32 KB size (I think this is REALLY good for a Class 10 on such little files…)
Anyway, as I explained in my other review, these “theoretical” results mean almost NOTHING to me, so, I immediately tested the card using the exact same _personal_ REAL-WORLD “torture test” I used with other cards, i.e transferring huge amounts of data of all sorts in read/write modes and simply _timing_ them, and stressing the memory card savagely FROM MY DEVICES, while actually _using_ them.
The results were VERY good, in my opinion, given the prices of this card:
I wrote 10.057 FILES (!) of ALL sizes and kinds, for a combined size of 15.3 GB using a Transcend S5 reader on my PC WHILE USING IT (e-mail, mouse, web, etc.), and it took 29 minutes and 30 seconds, which means a…
This review is from: Samsung 32GB Class 10 Micro SDHC Card Essential Class Card (Accessory)
This MicroSDHC card is extremely fast and high in capacity for it’s size. It even comes with an adapter for easy use with your computer. Because of it’s class ten speed, my smartphone has instant access to files such as games, music, music videos and HD movies without any delays. This product is an extremely good purchase and I highly recommend it.

Bought this after a dissapointing verbatim class 10 achieved a maximum 7.5mb/s write speed using h2testw_1.4. So far the read speeds on the samsung have been excellent and the write speeds have been just above class 10 minimum requirement. Using SD tools app on android 2.3.3 the card achieved an average of 11mb/s write speed and 28mb/s read, so seems to work nicely in the phone.
When i connected the card direct to my pc and run a 1gb file test on h2testw_1.4 it only achieved a speed of 9.53 mb/s write and 15.7mb/s for read.(please note this card has a hidden 1.5gb ext3 partition not visible in windows, hence only 13916mb available):
Warning: Only 1024 of 13916 MByte tested. Test finished without errors. You can now delete the test files *.h2w or verify them again. Writing speed: 9.53 MByte/s Reading speed: 15.7 MByte/s H2testw v1.4
Using Crystal Disk Mark the following results were achieved:
When transferring a 350mb video file the card averaged a write speed of 11mb/s.
I think the not so great speed results are probably down to the quality of my card readers. As the card’s primary function is for use in my phone, the most important speeds are those achieved within the device. So although the write speed isn’t as high as i’d hoped for, the read speeds are well above the class 10 required minimum.

|HTC Desire Speed Test Result,
Bought this after a dissapointing verbatim class 10 achieved a maximum 7.5mb/s write speed using h2testw_1.4.

Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 9.53 MByte/s
Reading speed: 15.7 MByte/s
H2testw v1.4
Using Crystal Disk Mark the following results were achieved:
Settings used 3 passes at 50MB
Sequential Read = 16.34 MB/s Write = 13.18 MB/s
512k random Read = 16.33 MB/s Write = 2.235 MB/s
Random 4kb queue depth 1 Read = 3.308 MB/s Write = 0.022 MB/s
Random 4kb queue depth 32 Read = 3.450 MB/s Write = 0.018 MB/s
When transferring a 350mb video file the card averaged a write speed of 11mb/s.
