![]() ![]() Si i will test if this card works ok, and if not i wil lreplace it. and i have but why so bad stats? i am sadīut from what you say, we dont know the minimum requirements. ![]() so probably i will need to sell the 32 gb if it doesnt worjk and get a 16 class 32 gb card.ĭoes anyone know what error message i will get if my card isnt fast enough? is thera a chance my card will work?Ģbox said if i rememebr correctly to have at least class 6. i will test this but i wanted to have bigger capacity. I have a 16 gb card for my camera that is class 16. my kard is kingston (supposed to be a good brand right? class 6 CrystalDiskMark is a small HDD and SSD benchmark utility that allows you to measure a drives sequential and random performance. When you plug the card in to your PC, you need to check what drive letter it uses (in my computer) then select that letter to run the test on in crystaldiskmark. You need to select the correct drive to test in crystal disk before running the test. Sorry Burnin, but you have run the test on your computer's hard disk rather than the card. ![]() of course i formated in 32 kb cluster as is adviced, but i cant check yet as i am waiting for the new brain ![]() What concerns me is that i formated the card when i got it. So am i fine? i am using a 32 gb kingston class 6 sdhc For that reason I'm not sure if Deve would like to simply tell us what the module requires as regards speed, rather than guessing based on the card benches, but hey, this is as good an estimate as I can make. Of course using a non standard card is not supported or endorsed by 2Box, and you modify the module at your own risk. Whatever card you purchase, make sure it is at least class 6 (preferably class 10), AND can achieve or surpass the speeds in bold above, and you should be okay. So we can say that the 2Box requires a MINIMUM sequential read speed of 17.34mb/s, and a MINIMUM sequential write speed of 13.30mb/s. I won't bother with the smaller read write sizes because the 2Box does not access or write to the card in such a way when in operation. Sandisk Extreme III class 6 card tested over USB2 with multiple 50mb files: The main figure you need to be concerned about is the sequential read and write speeds, as this is what the card will mostly be doing, rather than random reads and writes. So even if you buy a Class 10 card, that doesn't mean it will match the top speeds of the Class 6 Sandisk Extreme III. Remember that the Class system number only denotes the minimum write speeds for a card in a fragmented state. Using CrystalDiskMark 3.0 ( ), you can see the average/max read and write speeds of the Sandisk Extreme III Class 6, which is the card that 2Box ships with the module. In an effort to save people some time and money, there is a quick way to check if the card you have purchased is fast enough not to bottleneck the system. If you look at the drive identification on the bottom right, you will see that it shows a Lexar pro LRW 400, this being the adapter we use to connect the Samsung card to the PC.Hi guys, I am seeing a few posts around the place from some users who are experiencing problems with using a 'non-standard' SD card with the 2Box module. It even has many extra features such as endurance torture testing and a TRIM button feature to manually trigger TRIM on supported devices.Īnvil confirms pretty much everything we have already seen. Not only does it give an accurate look at transfer speeds and throughput, but also, it goes even further by identifying file sizes, disk access times, as well as system and device identification. Understand that CrystalDisk Benchmark is transferring samples that are highly incompressible, results of 97MB/s read and 83MB/s write are still excellent returns.ĪNVIL’S STORAGE UTILITIES PROFESSIONAL 1.1.0Īnvil’s Storage Utilities is the best software program available for benchmarking flash media. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. Thus, this benchmark will be a better representation of speeds to expect on a video or stills camera over ATTO. In our testing, we have left the benchmark settings to default.ĪTTO Disk benchmark displays performance results that match that of listed specifications, 98MB/s read and 89MB/s write.Ĭrystal Disk Mark is visually straightforward and is used for measuring the speeds at which your storage device reads and writes with random, mostly incompressible, data. Although this is not the best representation of media files which are, for the most part, highly incompressible, it is a good start and is still the main mechanism most manufacturers use to determine their product specifications. ATTO Disk Benchmark relies on testing different file sizes with highly compressible data. ATTO Disk Benchmark is a relatively easy-to-use benchmark tool. ![]()
