Overall, I’m not impressed. The price isn’t much different than other choices. SP is really lacking in detailed information that most serious users need to have to make their best choice. With some people, time is money, and this card is not suitable for quick transfers. If you have a professional task and need to get photos, videos, etc. transferred quickly, you might want to opt for one of the more expensive cards that can write over 45MB/s. (Most that do write 45MB/s are the same price as this one. Get faster for same price? Why not?) For the most part, people will pop this in a device and use it now and then. It makes a good entry level card. A professional that needs to move 30 gigs of data a few times a week will want to opt in for a card that can do it 4x ... MoreOverall, I’m not impressed.

I’m not getting near the speeds advertised, the write speeds are not impressive, compare to other cards at the same cost that are more than twice as fast. Lifetime warranty isn’t exclusive to this company. Most cards come with such a warranty. The card just works, and not that great at that! I was in hopes it would do better than a more expensive one I had in my blackvue as it constantly tells me to "Please Check SD Card" if I do not format the bloody thing daily. It is certainly the blackvue's issue as this card is the third to do the same thing. First being the manufacturers card OEMed with the product, second being one of the fastest on the markets costing more for the premium, and I thought a cheap entry level card should be given a shot as well. Desktop was reading it at about 20MB/s and writing near 15MB/s Sony Vaio 2 in 1 was reading it at about 40MB/s and writing near 20MB/s

Buying an SD card can be confusing due to the multitude of classes and speeds. These classes and speeds define a minimum write speed and the SD Association class SD cards as 2, 4, 6 and 10 to indicate a minimum write speed of 2mbps, 4mbps, 6mbps and 10mbps respectively. UHS speed is designed for UHS devices only and UHS 1 has a minimum write speed of 10mbps and UHS 3 has a minimum write speed of 30mbps. This card is UHS 1/Class 10 which has a minimum write speed of 10mbps and is actually rated for up to 85mbps (assuming the device supports these speeds). UHS 1/Class 10 is rated for use in HD cameras and video recorders. I currently own and use a Sony RX100 iii camera that is UHS compatible and records 1080 video and takes HD photos, I also have a Win 10 laptop with ... MoreBuying an SD card can be confusing due to the multitude of classes and speeds.

Testing the card in my camera was a little subjective as there is no real way to provide consistent metrics, however the card performed exceptionally well and I was not able to discern any difference in speed or performance between this card and the faster SDXC 64gb UHS 3/Class 10 SD card (rated for 95mbps) that is currently installed in the camera. 1080 video recorded without stutter and without any lag and HD images were processed quickly and without error. I installed both SD cards in my laptop and was able to retest using Cristal Disk Mark in UHS mode. After reformatting the Silicon Power UHS 1/ Class 10 SDHC card returned sequential speeds of 72.03mbps read and 38.87mbps write and the other UHS 3/ Class 10 SDXC card returned sequential speeds of 87.63mbps read and 47.57mbps write. Both cards felt equally speedy in the camera when shooting 1080 video and recording HD photos. This Silicon Power SD card comes with a full size adapter, a lifetime warranty, 32gb capacity and a ridiculous price. 5 eggs.

I like most have a bunch of these and some are better than others as far as speed, quality of filming (yes it does make a difference) and this one is 3 out of 13 that works flawlessly across all my platforms including DSLR 1080p recording. Yes if you use the right file size it actually transfers at speed it's rated at and it's fast on all other size files. For me the real test after doing transfers is how it performs in tablets for playing movies, running programs and then to my DSLR test on my Canon T2i ( never have done software upgrade). On laptops, it can even run games from it w/o getting too hot but of course a lot longer load times vs the hd. tablets it plays movies w/o hesitation to the DSLR, on many class 10 cards (as they claim) the pictures may be good ... MoreI like most have a bunch of these and some are better than others as far as speed, quality of filming (yes it does make a difference) and this one is 3 out of 13 that works flawlessly across all my platforms including DSLR 1080p recording.

This works flawlessly and the video as no flaws other than my skill plus add to that I could run video all times and never hesitated, only 2 others have done so well and many I have tested that claim to be class 10 don't come close to meeting all standards. I could upgrade the firmware on the camera but then sure they wouldn't stop running but I wouldn't know until editing about the quality so I choose to leave it alone and only use cards that pass the test. The other positive is that being a micro I can use it in anything I choose and use adapter to use it in full size SDHC devices. This is actually the best card I have now and runs smooth. It is a good buy

I have this in both the 32gb and 64gb versions. The speeds were similar between both. The main difference was that this 32GB version came formatted in FAT32, with 28.9GB Free space. I am happy with the read/write speeds. The only way you will get faster write speeds is if you buy a U3 rated card. I did also test this 32GB card in my Samsung Galaxy Note 4 phone, using its 4K video recording and it had no problems keeping up.

UPDATE: Got a second one of these and at the current price, they are a great buy. I kept my benchmark file sizes low as this is probably most common when reading and writing files from an SD card.

TESTING: I tested this on my laptop, Motorola X-Pure, Asus Zen-tablet, Full HD camcorder, and Fugi SLR. Speeds meet or exceed specs. Full advertised capacity present as expected. PRICE: The price today (6/21/2016) is among the lowest I have seen for a quality card from a major player coming in at less than $0.25 per GB - with free shipping. I would guess this may be a limited-time opportunity and could be related to SP trying to increase its US market presence. They have been around since about 2003 but I have not seen a lot of these in the US till recently. UP-TO SPEEDS: In camera or video applications, company-rated max or burst speeds are not too relevant for me. NEWEGG: would buy from them because of the large amount of counterfeit cards out there from online ... MoreTESTING: I tested this on my laptop, Motorola X-Pure, Asus Zen-tablet, Full HD camcorder, and Fugi SLR.

It is a surprisingly good card considering it is not a big name brand. I was getting read speeds around 40 MB/s and write speeds in the 10-15 MB/s range, however my equipment is a little on the older side. I do think that read speeds close to advertised are possible with this card, and 85 MB/s is extremely fast… in the ballpark of the original SATA hard drives. Write speeds are a little disappointing, but satisfactory for real world applications. The SD adapter worked fine in an external card reader. All the media I tested played perfectly from the card, including 1080p video. The one unpredictable intangible at this point is longevity. I could only test the card for 30 days because of review limitations. The big test will be to see if this card is still working to ... MoreIt is a surprisingly good card considering it is not a big name brand.

All the media I tested played perfectly from the card, including 1080p video. The one unpredictable intangible at this point is longevity. I could only test the card for 30 days because of review limitations. The big test will be to see if this card is still working to spec a year or two from now.
Died after 1.5 years in a treacherous and stealthy way. It would be better if it died in an open and explicit way. I wouldn't be misled then and didn't lose a lot of my new photos and records. I would then just replace the card. But it looked like it worked OK, and I trustfully continued to "use" it for very long time. I didn't even suspect that it didn't write any new data on it. I was very unhappy to find out that all last information was lost. Now I cannot format it, cannot write new files or delete old ones. I can read old files on it though. ------------------------------------------------------------------------------------------------------------------------------------------------------- About the speed.

I can read old files on it though. ------------------------------------------------------------------------------------------------------------------------------------------------------- About the speed. I have to admit that all my SDHC card readers (I tried 4) are probably not the fastest in the world. The speed also varied a little among different USB ports of my comps. The best result was through rear USB 3 port (although using USB 2 card reader), and the best speeds were: 1) “Real life” measurements (MiB/s = 1024x1024 byte/s): Write (copying a file ~2,5GiB from HDD) - 10,7 MiB/s; Read (copying the file from the card to NULL) - 17,5 MiB/s; Copy/Paste (copying the file from the card to itself) - 6,57 MiB/s. 2) CrystalDiskMark 3.0.3 x64 measurements (MB/s = 1,000,000 byte/s): Test 1: Sequential Read : 20.923 MB/s Sequential Write : 12.189 MB/s Random Read 512KB : 20.668 MB/s Random Write 512KB : 3.370 MB/s Random Read 4KB (QD=1) : 4.075 MB/s [ 994.9 IOPS] Random Write 4KB (QD=1) : 1.470 MB/s [358.8 IOPS] Random Read 4KB (QD=32) : 4.182 MB/s [1021.1 IOPS] Random Write 4KB (QD=32) : 1.560 MB/s [381.0 IOPS] Test : 1000 MB [E: 0.0% (0.0/14.7 GB)] (x5) Test 2: Sequential Read : 20.794 MB/s Sequential Write : 12.257 MB/s Random Read 512KB : 20.104 MB/s Random Write 512KB : 3.359 MB/s Random Read 4KB (QD=1) : 3.676 MB/s [897.5 IOPS] Random Write 4KB (QD=1) : 1.382 MB/s [337.4 IOPS] Random Read 4KB (QD=32) : 3.877 MB/s [946.5 IOPS] Random Write 4KB (QD=32) : 1.477 MB/s [360.6 IOPS] Test : 1000 MB [E: 0.0% (0.0/14.7 GB)] (x5) I wouldn't say the results impressed me. They are far lower than advertised "Up to" 15 and 40 MB/s. I guess they mean some theoretical, laboratory, not real-life speed. But, as I said, probably my non-UHS equipment is to blame. Anyway, it is a little higher than C10, and Copy/Paste speed is just 11 times slower than that of my very good ST3000DM001 HDD. In conclusion, if you don't need very fast card and short of money, I would recommend this card - it is OK. Provided it will not die, of course, like mine did.
This is a SDHC card so you are capped at 32 GB which is the capacity of the card anyway. 32 GB should suffice for photography, and for basic HD video recording at 720p or even 1080p. The card being UHS Speed class 1 also helps with reliability when taking video. Price point for this card is good. It is definitely a very good option if you are looking for a reliable memory card whilst on a budget. However if you are a memory hog like I am and need to store endless amounts of pictures, and HD video you may want to invest in an SDXC microsd card with a higher capacity. I haven't tested 4K video recording on this card but I don't expect to hold up if I were to take any 4K video. You are better off investing in a SDXC card with USH Speed class 3 certification which ... MoreThis is a SDHC card so you are capped at 32 GB which is the capacity of the card anyway. 32 GB should suffice for photography, and for basic HD video recording at 720p or even 1080p.

I copy and pasted three different 20GB+ MP4 files to/from this card three times each on my Windows 10 laptop with a USB3 SD card reader (using the included full-size adapter). I averaged the speeds out to come up with the 77.6 MB/s read and 23.3 MB/s write speeds. I did NOT measure speed with small-file transfers since those can be hit or miss for each person depending on the number and size of each file. For a general, generic review I prefer to provide and see sustained single-file transfer speeds. Overall I am very happy with the card. The price is great as of the time I write this review and the performance is as expected. Yes, write speeds can always be better, but in my experience flash cards always read a lot faster than they write. It's the nature of the game.
