PNY 64GB Elite Performance Class 10 U3 SDXC Flash Memory Card - 95MB/s, Class 10, U3, 4K UHD, Full HD, UHS-I, Full Size SD

Great card, delivers the promised speed of 95mbps. Sequential read speed is right at the advertised speed, and the write is lower (as expected) at around 45mbps. Still a very good number for a SDXC card at this price. If you plan on using this for a Raspberry Pie or similar, I would look elsewhere however, the random 4k read and write are quite slow. Used for a video camera or even a DSLR this won't matter, but for an OS type scenario you'll notice it. Overall a fantastic card and worth every penny of 44 bucks. Ran Crystal Disk Mark 5.1.2 with Transcend USB 3.0 Card Reader (TS-RDF5K) on a USB 3.0 port. The results are quite interesting. You'll see that this SD card is actually faster than most hard drives. Random read 4k is at 1542 IOPS (a fast disk drive will yield 150-200 IOPS). Random Read is nearly the same on 4k, both great numbers for an inexpensive SD card. The card is rated at UHS-1 U3 and should work well for 4k recording. Sequential Read (Q= 32,T= 1) : 94.568 MB/s Sequential Write (Q= 32,T= 1) : 66.713 MB/s Random Read 4KiB (Q= 32,T= 1) : 6.316 MB/s [ 1542.0 IOPS] Random Write 4KiB (Q= 32,T= 1) : 1.090 MB/s [ 266.1 IOPS] Sequential Read (T= 1) : 93.592 MB/s Sequential Write (T= 1) : 44.869 MB/s Random Read 4KiB (Q= 1,T= 1) : 6.193 MB/s [ 1512.0 IOPS] Random Write 4KiB (Q= 1,T= 1) : 0.855 MB/s [ 208.7 IOPS] Very happy with the product, will purchase more. Note: You'll see people have different read/write speeds on these cards. A lot of it has to do with the testing platform.

I've always loved PNY cards. I've used them pretty religiously for the past 10+ years. I think over that time, I've only had one card have a problem (and I've bought more than a normal share during a four year stretch as a professional wedding photographer). I'm currently using a Sony a7Riii and I shoot a lot in continuous shooting mode. These cards are fast enough to give me between 5-10 shots with little or no buffer (Shooting RAW at about 42 MP and JPEG simultaneously). I recently took a trip to NYC for an engagement session and shot 2000 images on one card with no issues. Really can't think of any cons on these cards. The cards function as expected for my intended use. I would imagine sports photographers might want cards with faster write speeds, but these seem more than adequate for portrait photography. No duds (I ordered 4), all function properly and have been used quite a bit since purchase with no issues. I'd recommend these cards.

I got this card about 10 days ago and have used it extensively. I was particularly interested in its U3 speed rating, since I shoot lots of 4K video at a speed of 100 Mbps (I use a Panasonic ZS100 camera). So far, this 128GB PNY SD card has worked perfectly, with no hiccups or problems. Even with 4K video at 100 Mbps, it can hold a LOT of video. Good price and no glitches -- excellent product. June 2, 2016 edit: I've now used this card for a month, extensively shooting 4K video. There has not been one glitch with this card -- excellent performance at a great price. May 19, 2017 edit: The record lock slider on this SD card fell out around May 1, 2017. Granted, I use my camera a lot and have this SD card in and out often. Still, once the record lock slider fell out, I could no longer shoot stills or videos... I could only read what was already on the SD card. I contacted PNY's customer service, which said to provide proof of purchase (my Amazon invoice) and to send it back. I just received a replacement SD card, which is the second photo below. I was disappointed that the first SD card failed, but PNY came through promptly with a replacement -- good for PNY!

I purchased this card to use with my brand new DSLR, the Canon EOS Rebel SL1. I wanted a high capacity and fast card that would allow me to photograph in RAW mode at all times and have room for any possible video that I might shoot. This card met every requirement and expectation that I had of it. Pros: 1. FAST! There is absolutely no delay after pressing the shutter release and the image is stored, it's seamless. 2. I opted for the 64 GB capacity and I was able to store over 2000 RAW images. 3. Transfer off of the card to my Mac was also extremely fast. I am using the built in card reader in my Mac Mini. Cons: 1. None I am completely satisfied with this card. It's fast, has excellent capacity, and just plain works perfectly in my application. It's a great value and I highly recommend it.

Let me begin by saying while I have a nice camera and a 100 - 400 lens, I am not a teckie so this review is about the performance I experienced without all the nits and nats about pixles, capacity, shutter speed in that tech language. I needed some additional cards because I was going to Cuba to bird and I knew I was going to be taking a lot of photos, trying to capture wild birds that tend to flit around a lot (so using a burst or sports setting to get multiple images hoping one is in focus, has the whole bird, etc.) and mostly seek to announce their presence with their song while keeping themselves hidden from predators. So I needed capacity, speed and confidence in my equipment. This card was great - not only could I get a lot of RAW images (which just eat up space) but the speed of transfer was very fast so the images were rapidly captured. I will be purchasing some additional cards as this one held 2 days of intensive birding (and lots of beauty shots of the countryside) before it was full. When I had to put in my 32 GB card I could really notice the difference in speed which surprised me that it was that distinctive. So I would recommend and intend to purchase again as I will be birding more this migration season and this card made my day easy as there was one less thing to think about and plan for. Ta T

good quality and value for money.

Been shooting a documentary in 4k on a7rii for the past week with two of the 512gb cards. Havent had a hitch so far - usually a sandisk guy, this is my first time with PNY so i cant speak for the longevity. So far so good!

普通に問題無くつかえています。 処理速度も問題なし。 良い買い物でした。

I purchased this to use with a TASCAM DR-40X. I had two cards it wouldn’t recognize and all the official media was really shooting up in price. This card is fast enough and gives you decent capacity. I will be filling the card before formatting to preserve its life and will report back if the card fails.

Es de lo mejor que hay, solo tengo excelentes reseñas de esta memoria, si quieres algo confiable para tus eventos ya sea foto o video o abmas y tener esa tranquilidad que la memoria no te va a fallar es tu opción, eh realizado entrevistas de 2 horas con esta memoria grabando a 4k 60 fps con una panasonic hx-c1000 y sin problemas, me atrevo a decir que es la mejor del mercado por ese precio, me costo unos $325 pesos mexicanos cada una, me compré un par, me arrepiento no haber comprado más, ahorita por el precio del dolar subieron muchisimo, pero en general un excelente producto. Sin duda recomiendo este modelo
