This is a review for the 32GB Sandisk '90MBps' SDHC Extreme card. As I have always found Sandisk a reliable and reputable brand, I have a load of these Sandisk Extreme SD cards in 32GB and 64GB sizes to use with my Olympus OMD EM-1 dSLR, Canon Legria HFG25 camcorder and the families other cameras. Plus my daughter's Sony Viao laptop has a recessed SD card slot that's ideal for efficiently backing up her important work files for college. 32GB is the largest SDHC card size and is pretty universal with most systems. As this 32GB was free to review via Amazon Vine, it was a bit of a no-brainer to ask for one, as a spare SD card in the camera bag is always useful.However if I was buying one of these Sandisk SD cards I'd always go for the 64Gb SDXC Extreme card instead, as it holds twice as many files and is generally better value per Gb storage (the 32GB being £15 and the 64GB being £27 as I write). Rated at nominally 90MB/s these Sandisk SD Extreme cards are more than fast enough for photo and hi-def 1080 video capture, so 5* (for 4K Ultra High Definition 3840x2160 video capture Sandisk recommend their faster & more expensive Extreme Pro SD cards, although this Extreme's blister pack also has the 4k Ultra HD compatible logo). The headline 90MBps is the read speed, not the write speed which is 'up to' 40MBps. My semi-pro Canon Legria HFG25 camcorder has two of these 32GB Extreme cards fitted, each shooting video for 4.2 hours in FXP mode or 2.9 hours in best MXP (Blu-ray) quality, and the SD cards work perfectly, even seamlessly auto-switching as one card fills up. Although standard SDHC/XC cards are cheaper, these 90MBps Sandisk Extreme SD cards are more future-proofed and will liven up photo capture speeds in compatible stills cameras (this 90MBps Extreme SDXC card replaced the noticeably slower Sandisk 60MBps Extreme card that otherwise looks identical).When you go up to 64GB the card moves to the newer SDXC format and this may not be compatible with older equipment - although even if the manufacturer says 'up to 32GB SDHC', that doesn't mean a 64GB SDXC card won't work so it will be worth trying (check on the internet if it has worked for others in your device). Perhaps the only negative is that this card can't fit into tablets or smartphones as they require the smaller microSDHC or microSDXC format size, whereas a microSD card can fit into a full size SD card slot via a SD adaptor. If we want to read a SD card directly via a PCs USB2 or USB3 port we use the

I use a variety of SDHC cards in digital photography and have found those produced by SanDisk to be reliable and have not suffered any losses of data, although I always take regular back-ups to the cloud for organisational purposes. I always select class 10 cards for best performance although the read and write speeds vary between brands significantly.The Extreme SDHC card offers high reading speeds of up to 90MB/sec and write speeds of up to 40MB/Sec; what you actually achieve depends on your equipment but this is one of the fastest cards I have come across to date. Basically the faster the write speed the better as this will affect how much data can be captured – too low a write speed and you may end up with grainy footage as some data might be lost.So the faster the write speed the better the chance you will record good video footage and not be disappointed when you transfer from camera to watch on the big screen.Write speeds also determine the extent of the time lag you may experience between taking photographs and switching between streams of video. Again, the faster the speed the better and using this card I was able to switch from video to still without experiencing anything like the delay I’ve been used to with a slower card.I tend to alternate between 32GB and 64GB capacity cards as these provide sufficient storage for an avid photographer to spend at least a day out and about, shooting photographs and video to my heart’s content without running out of space. You’d be hard pressed to run out in a day using the 32GB card, which in my case would enable around 4 hours of HD video or almost 3,000 photographs to be taken. I try to balance the desire to get larger capacity cards and thus (usually) the most cost-effective storage with the potential risk of loss of data should I accidentally misplace the card.Note that standard packaging currently means the card ships in a small plastic wallet inside a cardboard sleeve; very easy to open and the plastic wallet provides useful long-term storage.

I have a few SDHC cards for my photographic devices and stick to Lexar or Sandisk.With a new camera purchase I decided to buy a new card to go with it - the latest on offer at a decent price was this 'Extreme' '90MB/s' one in a twin pack, making for a slightly lower individual price (£26 for 2 vs £14 each, Jan 16).For me, the 'Write' speed is the crucial factor as it affects operation at the most important time for me ie when you're taking photos/video !Ultimately, the 'Write' speed dictates how quickly I can press the shutter/view images after the previous shutter press....[The card 'Read' speed is the one usually highlighted in product titles and on the card itself,BUT as that for me usually only dictates performance when transferring files it's not that important - especially as I usually start the photo/video file transfer procedure and leave the computer alone and go elsewhere for a bit as it is likely to be quite lengthy with 32Gb-odd of data, any time saving is less important for me !]So as this card was advertised as improving on that from my other, 'older', 32gb Sandisk 'Ultra' ('30MB/s') card and and my other 32Gb Lexar 'Premum' ('30MB/s') card (both C2012) I decided to buy it.--You do of course have to be careful when selecting the card to purchase as Sandisk, especially, are very good at keeping the same 'name'/appearance for a newly-issued card, changing only the small 'speed 'text' printed on the card label !When I checked, Amazon had advertised a 45MB/s, 60MB/s and this 90MB/s card in the 'Extreme' version - all look very similar....----I've just tested it vs my older cards, and the results were interesting - this card was quicker at writing than the older Sandisk but no quicker than the 'older' Lexar card....Here's the Amazon links to those older cards I own :

In all honesty, I bought this in error believing it to be an SD card fit for a phone, which IT IS NOT! (I accept I'm the only one foolish enough to over look this!)But when it arrived, I kept it anyway as I've a number of laptops, and whilst I use flashdrives often, the SanDisk Extreme 32GB SDHC is actually much better for transferring files between them. I didnt realise before this purchase that SD cards have different upload speeds etc, and this I imagine got it's 'Extreme' title thanks to it's speed. 90mb/s is really fast, and you really notice it when transferring media files. The only speed I've seen better is via USB 3.0 devices.The 32GB size is more than enough for a few seasons of your favourite tv show,a good handful of films or, fantastic for backing up your digital photos. This is now the purpose of ours. My partner backs up all her photos onto her laptop, as do I, and we use the 32GB now to save some 2000+ photos of our children. We do use Dropbox, and other cloud platforms, but after a friend lost hundreds of baby photos thanks to a 'cloud mixup', we opt for better safe than sorry. They estimate that the 32GB size can store up to 5.8k 16mp photos, but so far our 2000+ have only taken up around 8GB. I assume this maybe because not all of them will be 16mp photos.All in all, this wasn't the product I was after, but it is very easy to use and has proved a great backup space for us

First things first: there are, undoubtedly, cheaper 64GB SD cards available on the market, and if you're more concerned about the lowest price than performance, then this is probably not the card you are looking for.Having said that, this Sandisk card is an excellent performer. I've several of these in my various cameras, and I always carry a couple of spares in case I get somewhat trigger-happy. With modern 20mpix+ DSLRs, in some cases generating 50MB+ RAW files, it's really not hard to fill a 64GB card on a busy day's photography.It's worth noting that the claimed 90MB/sec is read speed, whereas what most of us are more concerned about are write speeds.It doesn't particularly matter if it takes a few extra minutes to download a card to the computer, but a full buffer preventing one from taking shots is an issue. And in that respect Sandisk are better than most: while the write speeds of their cards are undoubtedly lower than read speeds, they do seem to be consistently better than other cards from other manufacturers, even those with higher quoted read speeds.As always, it's worth doing your own tests with your own cameras to come up with the best cards for your needs, especially if you're using an older body that may not support UHS3 speeds.

I love the Sandisk range. Cameras can be fussy about memory cards so you do need to have some caution as to which ones you choose.I shoot Nikon (D750, D3 and D700) which take SD cards and Compact Flash Cards. I have always used Sandisk and always will. I'm also a bit paranoid at receiving fakes so I only ever buy from Amazon themselves and not 3rd party sellers. I never, ever touch memory cards on that famous auction site as I just don't trust them!!These work brilliantly in my D750 (I use two - slot two as a back-up). They write very quickly and this was most obvious after a trip to Vietnam in November 2015. I had used all my Sandisk cards up so I borrowed some other brand cards.Painfully slow is not even close! I missed shots due to the camera buffer not being able to manage with the other brand cards. They also took in excess of 15 seconds to view the images after I had taken the shots. I know all of this comes down to the class of the cards.Save yourself time and money and buy the largest and fastest cards you can afford and which are compatible with your camera from the onset. Your sanity and wallet will thank yo in the end!

At first I was excited to find such an inexpensive option that is capable of 90MB/s write speed. But then after reading the first part of the product description I discovered that these are only capable of up to 60MB/s write speed. Well, 60MB/s is still great at this price point so I ordered two!Well, the cards arrived today, so I decided to test one of them. I tested the card and found that it is writing at less than 50MB/s. So, I looked a little more carefully at the product information and see that only the 128GB and 256GB versions of the card operate at up to 60MB/s; the smaller cards are 40MB/s. It's very frustrating to have cards advertised as 90MB/s,and then find out in the fine print that the write speed (the most important speed for taking lots of photos with a high megapixel DSLR in RAW) is half that speed. So, minus one star for irritating advertising.Edit: The listing has changed to clearly indicate the write speed now, so I'm giving the star back. :)If you find my review helpful, please hit the "Yes" button on "Was this review helpful to you?"Thanks

From the number of these cards that I buy, you'd be forgiven for thinking that I had shares in Sandisk. The reason, of course, is very simple - quality. I learnt long ago that cheaper cards from other makers, did not offer the performance or reliability of higher end cards.I've never had an issue with Sandisk cards and I don't expect to.These live in a Nikon D610 - 24MP - one card as primary with the other as back up, shooting RAW and JPG. I don't really do any high speed action shots - the camera for one only bursts at 6fps. That said, I can shoot continuously for a few seconds before the buffer starts to fill up and the camera slows down. As these cards have quite a decent write speed,the buffer frees up quite quickly and continuous shooting returns. Single shot or low frame rate and these cards are fast enough that there would be no performance drop on the camera.They're not the cheapest cards, although Amazon do offer some good prices, but they are well worth the money.

I must have brought hundreds of SD Cards over the years and i'm still not quite sure why you don't just get one free when you purchase a new camera, i'd just purchased the Canon G7X which came to over £550 so you'd have thought they could factor one into the price...anyway.Whats really important with these cards is the Speed and this card claims 90MB/s which is pretty fast considering the average size of the JPG's i'm currently taking with my camera are only 5MB! You feel confident that this card is going to allow the full potential of the camera.64GB is plenty for my needs as I pretty much straight away copy the content to a central server for backup and archiving.The price at the time camein less than £25 which is great and in some cases £20 less than other vendors were charging which just goes to show that it's well worth shopping around.

This 32GB class 10 SDHC memory card works perfectly. I've used in in two digital cameras, as well as transferring the images to my computer - and everything functions exactly as it should. My primary camera is a 24MP Nikon, and in 'fine quality' mode I'm able to store 1,200 images on this care (or 5,500 in the 'basic quality' mode). That's a lot of photos! So it means I don't have to carry around spare memory cards, nor do I have to keep transferring the images to free-up space.The actual quality of the photos stored on this card is superb. And the transfer speed, from card to computer, is very fast. Given the reasonable price this item is available for, I highly recommend it.

A good fast card which I need for my Nikon D500. Has performed faultlessly for 10,000 shots with good read and write speeds. I use this as a back-up card in the camera and always shoot RAW so the file sizes are big. I was a little worried that the camera buffer would fil up on continuous shooting as it would be waiting to write to the card. In reality, I have shot up to 50 frames continuously without slowdown. Nikon claim 200 but I have never need to shoot past 50 and that is an exception as normally I shoot in bursts of 10 to 20 frames.I would need to use the card for a lot longer to speak of its reliability but so far I have not had any issues and I don't expect any either.

I bought this for my Canon 550d DSLR camera and it works perfectly. The write speed is class ten and allows me to record in Full HD, the highest quality this camera offers. If you are getting a "Movie has stopped" message, it is because your write speed is not quick enough. This memory card will fix that problem 100%. Just remember, with a lot of DSLR cameras you can only record 4GB of video (or approx 12 mins) at one time due to EU laws. No matter how fast your memory card is, you will never be able to record any longer.

I upgraded to this from a Sandisk Ultra, and the read/write speeds ARE much faster. I tested it in camera by doing both HDR & Multi-Frame NR, which usually take 4-5 seconds to write to the card, and with this, it's around half of that. Transferring to the laptop using my usual Picture Motion Browser downloader also took a fraction of a second. I can't put a Mb per second figure on, but it is most definitely faster. I need to try an in camera panorama for comparison, still, but I have no doubt it will be fast.

An extremely high-speed memory card designed primarily for HD and 4K video, though of course it can be used for storing other information. It's speed means you can snap away slightly more quickly on a digital camera, but the main advantage for photographers and videographers is obviously the ability to store a lot of high-definition recording without changing the card. The only caveat is that it doesn't work on all devices, though using a USB card reader enabled my elderly laptop to read it.

I bought four of these as I seemed to have a dozen devices needing SD cards and none to spare. These are reliable high speed cards, and I've never had one fail on me. They work great in cameras, and are fast enough for even the most demanding HD footage - not cutting clips short like some cheaper ones do.Use these in my game consoles, as impromptu memory sticks and in laptops as storage expansion. Read and write speeds are always exceptional provided you use a good card reader (I use this
