Kingston 16gb class4 h2testw benchmark

This new thread because I think this microsd deserves it
I've seen people looking for class6 and even class10 microSD cards, hoping for some wonderful performance, which is fine.
I did some testing on the memorycard I got at home and actually found out that one card I bought almost out of sudden impulse is the best of the bunch.
It's a 4 gb class 4 by Kingston, did score some nice number in h2testw, actually better than my SDHC class 6 16gb by transcend.
So i decided to buy a 16gb class4 by Kingston and this is the outcome:
Warning: Only 15287 of 15288 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 8.78 MByte/s
Reading speed: 15.7 MByte/s
H2testw v1.4
I must say I'm very pleased...
I got it for 21 £ (about 25 €).
Wish u all a nice day!
S.

I just bought the exact same card and waiting for it to arrive.
We'll see how it will perform.
Thanks anyway for your test's.

I'm running CrystalDiskMark right now to find out more about performance of this card!
Best Regards.
S.

Can you link us please
Where did you get it from?

CrystalDiskMark bench
...and here's the Crystaldiskmark test I just finished running (see attach).
Got it online from MyMemory
S.

Got the same one from mymemory via their ebay store. Using with a 1.5GB Ext3 partition for a2sd+. Using STT (from the Market), initial results were 4 + 4, after implementing sdcardfix got read up to 12. Using via the PC though in a sd adaptor, not ran any tests but copied just over 3GB in about 15 mins. V impressed seeing as it cost £21.99.

wow, so many coincidences, i have the exact card too, and is a speed demon indeed

Is the class 10 a lot faster than class 4 ? I doubt it! anybody got some benchmarks?
Well, according to this thread named "Kingston microSD 16GB Class 10 review"
the 16gb class 10 from kingston is just 10 mb seq write and 19 mb seq read vs this class 4 which is 9 mb seq write and 15 mb seq read
hehe guys, looks like we have a budget winner here

yeah, and scientifically, class ratings are only to rate minimum speeds, and most of them pass the mark waaaaaaaaaayyyyyyyyyyy over

Yep
And now for the economics of it:
kingston 16gb class 4 (+ some luck) = 24 €
kingston 16gb class 10 = 90 €
Just keep the luck factor in mind...
S.

I too have this same card and it is very good!
Cost me £20 from mymemory and performs really well.
Just installed the sd card speed fix on my phone and running a benchmark on the phone itself I get 7mb write and 15mb read.

In the search for ultimate performance, I swapped out my 16GB Class 2 for a Kingston 16GB Class 10, and how dissapointing it is!!
Test results using Crystal Disk Mark under Windows 7 with FAT32 partitionswere generally as follows. I also carried out the tests using SD Card Speed Test in Android and also using various settings but always with similar results...
Class 2: Sequential Read 16.67 MB/s; Write 5.289 MB/s
Class 10: Sequential Read 13.04 MB/s; Write 6.190 MB/s
Is this just a duff card!? Anyone else with Class 10 benchmarks???

Found it here for about £7 is this likely to be a fake? How do you know?

How does this card perform with 720p recording?

purely from the good reviews on here ive got one from mymemory for £19.99with an adapter....

hi, after reading all the messages, i'm thinking that my Kingston 16gb CL4 is dead...she's slower than my old kingston 8gb cl2.
Under SST sometimes it said "class unknown" or "class2" under windows it can't write above 1mo/s
purchase to mymemomy.com, thinking i going to return it for warranty

Hi guys. I bought a Kingston Class 4, 16 GB but it's very slow!!!
With Windows 7 the maximum writing speed is less then 4MB/s at best.
Is it damaged?

[Q] What class is my micro sd card?

Hi all,
This should be a quick answer...
How do I know what class my micro sd card is? Its a San Disk 8Gb. Can I assume the little 2 in a circle is the class? Would I be better getting a class 6 card?
Thanks.
Owen.

corect the number in the circle is the class. I running a class 6 samsung and in all honesty no earth shattering diff in 99% of thing phone can do

quick answer, yes it's (potentially) faster

However my Sandisk memory card doesn't have circle and number. Then how can l find out which class it is?

this is going to be hard for you to find out.. so let me try to be clear as possible and god help you with the steps.
first . you pull your memory card out...................

read the number -_-

Hello terzer,
without number on the card only a transfer test can give you an answer.
When you have an adapter to use the card with your pc card reader, you
can stop the time to transfer e.g. 100 MB to the card. Devide the 100 MB
by the time and you have the writing transfer rate (e.g. for 10 s:
100 MB / 10 s = 10 MByte / s ), repeate this with reading the 100 MB
back and you have the reading transfer rate.
Class 2 - 2 MB/s minimum writing
Class 4 - 4 MB/s minimum writing
Class 6 - 6 MB/s minimum writing
Class 10 - 10 MB/s minimum writing
Stop time after finished copy process - pc somtimes uses write cache
and displays multiple of real rate.

There's a sd card speed tester on the market. I forget the exact name. Try that to find your class.

I test transfer speeds with "J Disk Benchmark". No idea if it's the best or anything, but it gets the job done and it's free

It's "SD Card Speed Test". I guess someone with a huge imagination named it

Just ordered a new 16Gb Class 10 Transcend card from 7dayshop.com £16.45 delivered
Just have to wait an age for RM to deliver it, over Christmas.

this will be far more accurate than the class rating on the card and you can really compare cards decisively

Hmmm just used "J Disk Benchmark" to test my SD CARD it suposed to be a 16 GB class 4 . read speed 2,4 MB write speed 1,4 MB so its more a class 2 than a class 4 card !!

My 8gb class 4 Samsung maxed out 6 Mbs transfer speed last night.

Actually if someone could point out the differences in the classes and which one is "recommended" on the DHD?? I would also like a 16Gig...
And how to check what class I have on the DHD now?
Cheers!

I can answer The class thing the higher the class the faster it reads and writes which it recommends nothing below a class 4 for hd video recording at present in got a 16gb class 6 works great just wanting more space

yeah true would make it harder to now if you getting real deal, probly only way to know your getting what you ask for is import from a decent website. but you can always test the class of sd card by it transfer speed on pc as a class 6 should be able to transfer at around 6mb/sec if im right. but can your pc read/write at 6mb/sec i know mine can't lol

I'm pretty sure mine does... an i7

I have a 32gb class 4 and its perfect for everything, not noticed any slow-downs and HD recording is fine. I couldn't find any class 6 when I was looking but no regrets getting a 4, will transfer a mp3 album in a few seconds (if that's any measure). Cost me £56. It's by integral

The class shows the minimum read/write speed of the card as shown below
Rating Read (Mb/s) Write (MB/s) Class
13× 16.0 2 2
26× 32.0 4 4
40× 48.0 6 6
66× 80.0 10 10
It is possible that a Name brand class 6 card, could out perfom a no name class 10 card as the speeds are minimum, I would tend to avoid anything slower than class 4 as it MAY introduce lag involving SD read/write operations​

To those who have 32gb cards, what brands are they?
Contemplating between transcend and sandisk. transcend is a bit cheaper though. I just dont know anyone who can vouch for transcend.

I bought one from MyMemory.co.uk, just their own branded ones was about £52 class 4 couldn't be happier with it

On looking up the official standards of MicroSD cards http://www.sdcard.org/developers/tech/sdhc/ it only talks about differences in speed ratings such as class 2, class 4 ect. So I assume that HTC are advertising the Desire HD as only supporting class 2 MicroSD cards. I would like to know if anyone can confirm if using the USB cable to transfer data to a PC is actually getting faster speeds using a higher class MicroSD card than class 2 standards?

HTC isn't saying that the DHD supports class 2 only it just doesn't specify. (the micro-sd 2.0 thing is completely different to what you're thinking about the 2.0 means it supports micro-SDHC not that it supports class 2 only. and about the speed difference, I have a class 2 8GB micro-SDHC and that writes at 2MB/s and reads at 4MB/s, a class 4 16GB that writes at 4MB/s and reads at 5MB/s, and finally a class 10 32GB that writes at 12MB/s and reads at 15MB/s. (All tested on my Desire HD) So there is a HUGE difference between classes 2 , 4 and 10 when copying through USB.

Hello,
what class 10 32GB do you have?
best regards huggy

It's a Kingston. I would tell you the model number but I chucked the rubbish away.

I bought a Toshiba 16gb class 4 and I am completely satisfacted in comparison with the stock (samsung) ! It's faster and more reliable !!!

Samsung 32GB Class 10 or Sandisk 32GB Class 4

I'm very tempted to get one of these cards. I did search and read a lot about the sandisk card. But there isn't much about the samsung class 10 card. Can someone please shed some light on it.

save yourself some cash and get a samsung 32gb class 6,

I try both on my Sensation....i think Samsung is just a little bit better but noothing special.

samsung or sandisk
you should look at the sandisk mobile ultra 32gb class 6.
not the cheapest card,but I would say the undisputted class six speed demon.

take the class 4 one, you dont need the speed of a class 10 on the phone it's just wasting money

Have a search for one of the SD card threads which should have detailed benchmark data in. Maximum read and write speads are not the only important factors. If you mean this one http://www.amazon.co.uk/Samsung-MB-MSBGAEU-32GB-Class-Micro/dp/B005FY61EK, I can confirm it works well. I benchmarked mine before I put anything on it and, in megabytes per second it scored:
Seq Read: 20.06 Seq Write: 12.10
512k Read: 19.82 512k Write: 11.86
4k Read: 4.777 4k Write: 1.270
4k QD32 Read: 4.917 4k QD32 Write: 1.271
The 4k read and write values are apparently very important for us as the phone will read and write lots of small files to the SD.
These speeds ECLIPSE my Sandisk 16GB class 4 card and explain why Android on my old HD2 was slow whenever I put apps n stuff on the SD card. Hope this helps you make your mind up. Try and find that thread : )

I'm looking at the Sandisk Mobile Ultra class 6. I think I will go for that. Anyone's got one yet?

Saw this in a shop today and thought of getting it but it's a waste of money really. I think I'll just go for the Class 4 or 6 32 GB sandisk card.

Hello there!

isn't a class 10 better for multi-booting a rom from an sd-card? I think both brands are pretty good

I got the class 10 Samsung the ouzo posted the link for, blazing fast & apparently waterproof, so if your phone ends up in a beer glass (happens more often than I'd like) the data is safe

It is always better to buy the fastest card. My choice would be Samsung Class 10

Yep. Go for speed first.

16gb class 4
I've been using a 16gb class 4 sandisk and it works exactly as stated. Usually writes between 4-5 MB/s and reads between 20-30 MB/s. Its been very consistant and I've had no problems. If your looking for a dependable card id go with the sandisk.

I have one of the original 32gb SanDisk Class 2 MicroSDHC cards and a PNY Class 10 32gb
So far I haven't noticed a difference, Other than I filled the SanDisk already and got the PNY so I could archive the SanDisk

Does the clad of your memory card affect how full hd videos record ?? I'm using a class 4 and it sometimes freezes during playback then picks back up would a class 10 eliminate this.

Which micro SD card is better?

Hi!
I am deciding between these 2 micro SD card's. Please tell me which one of these 2 is better.
1) PNY 8GB MicroSD Class 4 Memory Card
2) RetailPlus 8GB Class 10 microSD Card (MEMS8GC10)
Thanks

You don't have to judge between them. Both will be awesome somehow. Anyway I vote for PNY.

Class 10 will be much faster, minimum 10Mb per second write speed. (If it really is a class 10)

I got a 16 GB Class 4 SanDisk microSD for around $20 or $30 while on sale. I find that you can often find these better known brands on sale quite often. Check weekly flyers of stores nearby.
Personally, I got mine from Tiger Direct.
EDIT: As for your two options, I do not need the speed that a class 10 microSD has to offer. I would just go with whichever is known to be more reliable. Exactly why I would opt to find a SanDisk on sale.

Class 10 is faster for read/write data.
Sent from my GT-N700 using xda app-developers app

Class 10 MicroSd is far better
Class 10 MicroSd is far better as it is also recommended for RAM expander app

Odp: Which micro SD card is better?
Class determine only write speed not read. If you are using card simple as storage you dont really need class 10 but ofc copying files will be faster. Class 10 is recomended for making hi res movies, gaming or ( as mentioned above) swap. Personally i recomend Samsung class 10 cards, no problems and nice speed.

i would say go with class 10 it is the faster out of the 2

as it is stated above if u use it for swap etc., a high speed card would be very handy, but as for just storage i'd go for pny.. btw take a look at this topic for the speeds: http://forum.xda-developers.com/showthread.php?p=15269669#post15269669
