- Reviewed in the United States on September 11, 2023Capacity: 128GBStyle: Card OnlyVerified PurchaseAlright fellow photogs and camera aficionados of the Amazon world, let's talk SD cards, shall we? Now, I'm rockin' the Lumix S5 IIX, which, yeah, she's a bit high maintenance and demands those UHS-II cards. But here's where things get interesting.
Enter the SanDisk 128GB Extreme PRO SDXC UHS-I Card. While my Lumix loves those UHS-IIs for video, when it comes to snapping those killer stills, I've been leaning into the embrace of this SanDisk card. Why, you ask? A few tasty reasons.
1. Price Tag Magic: Okay, so I scoped out a few places, and Amazon's price for this card? Pretty unbeatable. Like, 'is-this-a-typo?' level unbeatable. Compared to some other online giants (you know who I'm talking about), this is wallet-friendly territory.
2. Performance: Don't let the UHS-I label fool you. This card is quick, reliable, and when capturing those high-res images, it does its thing and does it well. No lag, no fuss. Just pure, unadulterated photo goodness.
3. Capacity & Quality: 128GB means I'm not in a rush to transfer photos every other day. And with SanDisk's rep? I'm confident my shots are safe and sound until I get around to it.
In a nutshell? While UHS-II cards have their spot in the limelight (especially for video needs), for still photography, the SanDisk Extreme PRO SDXC UHS-I is like that sneaky, economical MVP in the background. If you're after quality, performance, and a price that makes you feel like you've pulled a fast one on the system, then give this card a shot. You might just be as pleasantly surprised as I was! 📸👌🛍️
- Reviewed in the United States on October 8, 2023Capacity: 128GBStyle: Card OnlyVerified PurchaseAs a photographer, having a reliable and high-performance memory card is crucial for storing and transferring precious photos and videos. The SanDisk 128GB Extreme PRO SDXC UHS-I Card (SDSDXXY-128G-GN4IN) is a popular choice among photographers, and here's a review from that perspective:
**Capacity:** With a spacious 128GB capacity, this SD card provides ample storage space for your high-resolution photos and 4K UHD videos. This is especially beneficial for photographers who shoot in RAW format or do extensive video recording, as it minimizes the need to frequently change cards or offload data during a shoot.
**Speed and Performance:** This card is rated as a UHS-I Class 10, U3, and V30 card, which signifies its high data transfer speeds and ability to handle 4K UHD video recording. The U3 and V30 ratings are crucial for ensuring that the card can consistently write and read data at the necessary speeds, preventing any buffer overflows during rapid shooting or video capture. This card's performance is reliable for capturing fast-action shots and high-definition video content.
**Durability:** SanDisk's Extreme PRO series is known for its durability. This card is built to withstand extreme conditions, including shock, temperature variations, water, and X-ray exposure. For photographers who work in diverse environments or shoot in challenging conditions, this rugged design is a definite plus.
**Compatibility:** The SDXC format ensures broad compatibility with a wide range of cameras, including DSLRs, mirrorless cameras, and camcorders. However, it's always a good practice to check your camera's specifications to ensure it supports SDXC cards.
**Price:** While this card is not the cheapest option on the market, it offers excellent value for its performance and reliability. As a photographer, investing in a quality memory card is essential to safeguard your work and ensure smooth shooting sessions.
**Brand Reputation:** SanDisk is a well-established and trusted brand in the memory card industry. Their products are widely used by professionals and enthusiasts alike, which adds to the card's reliability.
In summary, the SanDisk 128GB Extreme PRO SDXC UHS-I Card (SDSDXXY-128G-GN4IN) is an excellent choice for photographers who require a high-capacity, high-speed, and durable memory card for their work. Its reliability, performance, and compatibility make it a valuable addition to your photography gear, especially if you frequently shoot in RAW format or record 4K UHD video.
- Reviewed in the United States on December 24, 2020Capacity: 1TBStyle: Card OnlyVerified PurchaseI purchased this 1 TB card to be used as a permanent secondary storage media for my almost full laptop. I just get it and test it for more than 4 hours with adhoc software and got this result:
Warning: Only 976255 of 976375 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 63.6 MByte/s
Reading speed: 64.0 MByte/s
H2testw v1.4
Keep in mind speed depends on many factors, so do not blame the card.
I plan to keep it within my laptop card slot. I think it is a great solution to store media files. It works great for my win10 laptop but not for my macbook pro because it does not come with any card slot, and card adaptors can fail
I am a youtuber with more than 160000 subs, but do not plan to use it with my cams, because I do not want to risk many videos on just one card. I recently lost 3 excellent action videos due to a bad card adaptor for my macbook pro, so I do not recommend to use this card for your cam, but I do strongly recommend to use it as a permanent storage media. I have a 256 GB sandisk card for one of my cams, and always try to transfer my videos as soon as possible.
I received my card pretty fast (amazon is doing it great now) , safe and good package. I recommend buy directly from Amazon
I will try to update this review next year
- Reviewed in the United States on December 27, 2024Capacity: 64GBStyle: Card OnlyVerified PurchaseI have always preferred to get a SanDisk whenever I needed a storage device for my cameras. SanDisk is the only branded I trust to produce quality storage devices with incredibly fast speeds of uploading and downloading.
The 64GB Disk is perfect for travel photographers like me. The disk inserts into the camera with ease and can be inserted into my computer just as easy and immediately upload all the high data photos instantaneously. I will always choose SanDisk!

ソニコン1Reviewed in Japan on April 24, 2021
5.0 out of 5 stars ノートPC (UHXC3) のカードスロットで交換式HDD代わりとして購入。取説では512GBまででしたが、使えています。
Capacity: 1TBStyle: Card OnlyVerified PurchaseノートPCのカードスロットに常時IN 、ただし、OSの書き込みキャッシュは無効のまま使用中です。
5年前の512GB(amazon 販売)が結構前から一杯一杯で新しい写真を入れるたびに古いのを消して( 外付けHDD にコピー )いて、1TB が出たら、買い換えたいと思っていたのですが、出来れば購入歴のある SanDisk か 東芝 (KIOXIA) で、余り高くないのを と言うことで、今回 わりと安かったので購入に踏み切りました。
ただ、取説によるとノートPC のカードスロットが 512GB に対応しているが、1TB 対応 を歌っていなかったので若干不安は有りましたが、870GB 程書き込みましたが、問題は出ていません。たまたまなのか、単に当時は512GBまでしか出回っていなかったので、512GBまで対応と書かれているかは分りませんが、私のはOKと。
また、シーケンシャルリードの公称値を見るために、メーカー純正のカードリーダーも購入してテストしてみました。
メーカーのカードリーダだと シーケンシャルのリードは公称の 170MB/s より少し遅く、ライトは公称の 90MB/s より少し早い結果になりました。ただ、ランダムが遅いです。
ノートPC の方は、シーケンシャルは遅くなりますが、ランダムはメーカー品より速くなっています。基本はこちらで使用するので速度として問題ありません。
ただし、ELECOM MR3C-D011(USB-C 接続)では、使用できませんでした。この製品も 512GB までの対応となっていて、こっちは本当に 512GB まででした。
容量/空き容量 953.4GB

2021/07/26 追記
アロケーションユニットサイズが512KBもあるのでご注意を。一杯になって、ファイルサイズの合計に対して。ディスク上のサイズが大きかったので、小さなファイルを沢山入れようとすると入りません。通信ログ(メールやチャット等のテキストファイル)が数GB占めていたので、こちらはノート本体のSSDに移動しました。四百MB位になりました。基本は写真用(JPG 約5MB ~)なので、問題無いです。
