PNY Elite Performance 256 GB High Speed SDXC Class 10 UHS-I, U3 up to 95 MB/Sec Flash Card (P-SDX256U395-GE)

Works great, very fast, no compatibility issues with devices that support SDXC. Was able to do 93.53MB/s sequential reads and 56.63MB/s sequential writes. The random writes are slower, so this wouldn’t be great for an OS (like a Raspberry Pi). But perfectly designed and very fast for a camera recording images or video.

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!

My camera does not recognize it as being UHS-I, it is a Sony a6300….none the less the data rates are pretty good but the burst rate is little more than Sandisk’s Extreme line and can’t hold a candle to any of my Sandisk Extreme Pro’s….I can record 4K at 60Mbps but Sony requires UHS-I cards for 4K at 100Mbps and the card is not recognized as such….I generally stick to Sandisk and I suppose this is why. That said I paid 22.99 USD for 64GB’s which is a pretty good deal, I probably have a million Sandisk cards but I was hoping PNY could compare. I will try the card in other devices but I did extensive continuous shooting with the a6300’s 11fps+ continuous 24MP sensor and the buffer clear a lot slower than cards that were Class 10 but not UHS-I by a slight amount and Sony’s UHS-I seemed to be superior with Sandisk Extreme Pro maintaining its deserved status as king.

If you just need 64GB’s for everything up to 1080p60 at 50-60Mbps and this card is cheaper than Sandisk, Sony, or Lexar then you are absolutely fine, most of you will be shooting AVCHD at 24-28Mbps anyways but if you need true UHS-I or near UHS-II performance look elsewhere.

Have you ever had to wait forever for your camera to save a photo you just took? If so, that’s probably because you have an SD or SDHC card that’s too slow for the size of the images. Although this 95MB/sec PNY card is not the fastest card available, it approaches the current upper limit. My shots get quickly transferred to the card so that I can take the next photo. While I cannot tell this difference between this card and a 90MB/second card I own, it is a world of difference from 80 MB/second card I’ve used. As with most SDHC cards, read-speed is slower, though, in this case, still quick.

Because I tend to upload photos to my computer fairly often, this 32 GB size is plenty big enough for me. I rarely approach a full memory card. If, however, you tend to go for long stretches and/or take thousands of photos before returning to a computer, you might want to consider a larger capacity for, IMO, not much more money.

I’ve found PNY to be a reliable brand, which is why I bought this card when I decided a needed a spare card. It has now become my main SDHC card with a 90 MB/sec one as a backup.

Engineer here. So I have to rate this as a 4 star due to it lying to us a little. You are likely buying this because you have a mirrorless camera and need ultra fast recording speeds of 95 MB/s

I just ran F3 a testing utility. We got

Average writing speed: 65.25 MB/s

Cool, but the package says Up To 95 MB/s. Granted that is likely the peek max, not the average, but we the users want to know if it will actually work for 4k video. That said, it does go above and beyond its “technical” classification. (those useless symbols that are greek to even most engineers on the card) The SD XC, with a roman numeral one, or “I” means its rated for 12.5-104mb. Which is pretty useless. The clas U3 on the chip means it has a Minimum of 30 MB/s, which is equal to a v30 for video.

TLDR, the fine print it is running to spec but clearly deceptive in it’s perceived performance by its packaging.. But maybe look for a class 2 card, or a Video class of 60 or above. If you don’t have a mirrorless and you aren’t doing 4k video, then buy a cheaper card than this.
