Transcend256GB CompactFlash Memory Card 800x (TS256GCF800)

I have been using these for a few years. This is a great brand and has great quality. I reordered these a few times.

Have an old ipod mini from 2005 that's hard drive has been toast for years. I still wanted to use it again after realizing the old hard drive was unsalvageable. Looked up youtube videos, and found this one is a perfect replacement for those old apple HDD's. Plugged it in and it worked immediately, and I love the upgrade in storage. My ipod originally had 4gb of storage, now it has 32 and I can enjoy all of my favorite songs from the early 2000's that I grew up with since I've re-uploaded them. Very pleased with this purchase.

Thankfully I had another cards! I bought this card specifically to feel more secure with plenty of storage for weddings. Toward the end of the day it just stopped working. I took it out, put it back in and the images showed again. So at that point I switched to a new card.When I got home I tried to upload and again they wouldn’t show. I took it out, put it back in. They showed long enough to upload….then it failed again. And since then I haven’t been able to get the photos to show again. Scary for a wedding photographer!!This is the brand I typically use, so I’m a little thrown off. Maybe it’s a bad card, but now I’m nervous to order this brand.

Overall I'm really happy with these cards. I am a professional photographer using a Canon 5diii, and I always record duplicate RAW files to both the CF and the SD slot. My raw files usually range from about 20-25 MB in size, and I often shoot short bursts. These cards are fast enough for my purposes (bursts of 5ish photos in a row without having to wait for buffering). They also download pretty quickly for me, though that will vary based on your computers RAM, etc. I have used these cards for the past year and haven't had any issues with card failures/corrupt or lost files either. I know there are faster cards out there, but they are also more expensive. I have found these to be reliable and fast enough for shooting RAW on the 5dii with an SD card recording simultaneously. Until Canon improves the speed of the backup SD slot, these are awesome cards for the money.

I bought this to load DOS on to it. Well Windows 98 (DOS) it worked great, then I was playing around and decided to load Windows 7 on it... Well that did not go so well. Transcend does not allow for bootable CF drive at this price range, so much for that idea. What about XP? sure enough Windows XP loaded on the FAT32 file system works! Little tricky, have to setup as raw Windows 98 boot files then install keeping as is (multi-boot, remove Windows 98 option later). What the amazing part is, I am running it on an old Athlon-XP CPU & MB and it is sooooooooo faaaaaaaaaaaaast! Loading Windows XP, launching apps so fast.

So I've had 2 of these cards for the past two years and the have worked flawlessly. No slow read speeds, and no bent pins. I use these for weddings, events, and client sessions. I've also used them in the rain, 100 degrees and down to 18. Not. One. Problem. Pro-tip, insert CF cards slowly and evenly to avoid getting bent pins. You'll waste half of a second, but your heart won't drop when you smash a pin. Come on people, you can't see the holes or the pins and you're just going to shove it blindly into a tight dark space?

I ordered the Transcend 32 GB 800x CF card and ran a speed test on it comparing it to the Transcend 32 GB 1000x card. Read speed on the 800x was about 130 MB/s whereas on the 1000x it was about 115 MB/s. Write speed on the 800x card was 40 MB/s and 60 MB/s on the 1000x card. Interesting that the 800x card had a faster read speed than the 1000x card. It wasn't until after I ran the test that I realized that something was very wrong with the card I ordered. I opened the card in a finder window and clicked "get info" on the card. It showed that the capacity on the card was 7.92 GB, so what was packaged and sold as a 32 GB card was actually an 8 GB card. I promptly returned the card and will be receiving a new one in two days.If the new card I receive has the same read and write speeds (and is actually 32 GB as advertised and labeled), I will be happy with the card. I've ordered many CF and SD cards from Transcend in the past and have never had one fail, so I've been loyal to the brand, but with this occurrence, I'm really reconsidering switching to Sandisk or Lexar. At this point, I'm really disappointed with Transcend's quality control. I really hope that Transcend will resolve this problem. I will update this review when the new card arrives.**Update 8/15/14**New card was sent overnight. I shoot on a Canon 7D. I plugged the CF card into my computer first to make sure the capacity was actually 32GB this time. Capacity seen on computer was in fact, 32GB. I stuck the card in my Canon 7D and went to format. Under the format menu, the card shows up as 32GB but, after formatting, it shows only 8GB of space. It seems that this card is incompatible with the Canon 7D. I re-partioned the card on my computer to 32GB and stuck the CF card in a C300, and it worked fine in the C300. Returning the card again and will buy something else.

Transcend compact flash cards are absolutely the best. Have never had one fail ever and they hold up extremely well. The price is always very good compared to Sandisk and lexar. Ive had several lexar and patrio cards fail on me in the past. Sandisk has a good reputation with me as well but the sandisk version is slightly more expensive. Cant go wrong with either brands honestly. Im a professional photographer and run thousands of images through my compact flash cards on a weekly basis and they hold up so they are 100% professional grade.

I just got a Canon 1DX II and it records 4K video in a good image quality but horrendously inefficient motion jpg codec. i have a 128Gb CFast which was extremely expensive and is necessary for 2160/50p using this camera so ideally i wanted a higher capacity CF to capture a decent amount of lower 25p framerate 4K - so the Cfast can be reserved for 50p duties. Of all my existing CF cards though only 1000x Lexar Professional was fast enough to record 2160/25p - and at 32Gb only eight minutes worth. This 800x CF in the 256Gb looked to be extremely good value and having received it today appears to indeed be fast enough to maintain reliable 2160/25p video on the 1DX II. Obviously more complex scenes need more data but higher ISO also increases noise and encoding complexity: in early test at iso 12,800 the CF kept up fine so i am sure it will prove to be okay. The data requirement for a 3 min 6 sec clip was 11.4 Gb which is a write speed of 61.3Mb/s and should give me 64 mins of 25p recording (+ my 128Gb Cfast giving me 8 mins 50p).I don't expect it to be as fast as my lexar 1000x for recording bursts of raw stills but will be trying it in a Canon 5D3 at a wedding i'm shooting stills at tomorrow and should it perform less than reasonably fast that i expect from it I will update this review.

I have two of these cards plus a 16gb transcend card which I use on my 7d mkii.I shoot thousands of photographs at airshows at 10 frames per second and have never experienced any problems with this card - no buffering issues or slowdowns. Perfect!I won't use anything else.

I have used these cards for a year or so in my Canon EOS 7D, 7D Mark 2 and 5D Mark 3 and I have never have any problem with them.I generally remove the card and put it in the PC CF card slot when I download content to the computer and have always found them to work well.They are fast enough for writing photos and videos and seem really well made and reliable, so I think they are one of the best value cards you can buy.

Amazing reliability, I trust this card with my most important work, never had a problem with transcend. For those choosing between this and sandisk, I use both and I’ve never had a problem with either but I’ve heard more horror stories involving a sandisk Cf than a transcend Cf card.

Terrible product. I took photos using it, they all reviewed in camera fine. When I went to transfer to my PC, images were completely deleted from the CF both in camera and when attempting to view on the PC.In my long time as a camera user, I have never had a memory card issue until Transcend. Rubbish product. Save yourself the deleted footage and buy from a proper company with better customer service too.Transcend even want me to waste my own money again and pay for postage for returns. Terrible customer service. Terrible product.Do not waste your time
