Hello everyone, I am a big tree under the clouds, a photography veteran who likes to toss equipment, please follow me and enjoy the fun of tossing with me
The time has come
Before you know it, 2024 is almost halfway through, and the long-awaited 618 is coming! I believe that all of you have already begun to gear up for the favorite baby in the shopping cart, right? It just so happens that I recently bought a new Nikon ZF, and its unique SD+TF card dual SIM strategy really gave me no idea
A wide variety of memory cards
But as a standard photographic equipment party, I have also bought dozens of various memory cards over the years, how can such a trivial matter as picking a card for a new camera be difficult for me? So after some research and tossing, I think I can take this opportunity today to talk to you about the purchase strategy of memory cards
It's important to figure out the specs
Open the shopping website and listen to it, huh~ Why is there so many kinds of doorways for a small memory card? How can the price of the same storage capacity be hundreds of dollars? It's sweet what's going on
A variety of memory cards on the east
Looking at the high and low prices of various memory cards, is it not a buzzing brain? The only voice that echoed in my ears was the sentence "How to choose this TM", right? Don't worry, if you want to figure out the "mystery" of this, we just need to understand the rows of small characters on the memory card surface!
Lexar 1800x128G memory card
Take the Lexar memory card in my hand as an example, you can see that there are two rows of parameter identification on the card surface, the 280MB/s R speed above is the highest read speed, and the 210MB/s W speed is the maximum write speed of this card. Of course, these two parameters are the best values for the performance of the card in theory, and whether you can achieve this performance in actual use depends on whether your card reader and the transmission interface are properly coordinated. And the row of parameter indicators below them is the very important speed class indicator of the memory card.
Schematic diagram of memory card specifications
First of all, let's start with the V60 logo on this card! This V60 is a level of VHS video speed, this specification level is mainly due to the increasingly strong demand for video shooting in recent years, as we all know, the requirements for the speed of the memory card are also quite high for video shooting, in order to allow video users to distinguish the speed specifications of the memory card at a glance, there is a speed level that supports higher identification-VHS video speed class. The number after V represents the minimum write speed, and the criteria are as follows.
V6——6MB/s
V10——10MB/s
V30——30MB/s
V60——60MB/s
V90——90MB/s
Obviously, the higher the number, the faster the speed, taking the current high-quality 4K video shooting needs of various camera manufacturers as an example, if you want to shoot smoothly, you need at least V30 card, like my Nikon ZF when shooting NLOG 4K60 frame video, V60 card is a must. And a machine like Sony, if you want to shoot 4K 120 frames video, a V90 memory card is a must.
Samsung 128G white card
On older SD cards, this specification for SDXC+ digital is more common. The SD Association has standardized and classified the transfer speed of TF memory cards and SDHC, and defined several Class levels according to the minimum read and write speed, and the number after Class indicates the minimum read and write speed of the memory card. The Speed Class (SD bus) logo on the memory card is circled with an unclosed circle with a number – the 10 that is circled after the card's SDXC 1.
Class 2——2MB/s
Class 4——4MB/s
Class 6——6MB/s
Class 10——10MB/s
In this way, the reference significance of this specification is not so big at the moment when a photo is more than ten MB, and the 3 grade logo behind it is more referential.
SanDisk's old SD card
This speed grade mark in the "water cup" is the UHS speed class! The UHS speed class is marked with the letter U on the memory card, and the middle of the U is marked with the number of the grade, which represents the grade of the card in the UHS speed type. UHS speed classes can be divided into two grades: U1 and U3. The theoretical speed of the U1 card can reach more than 10MB/s, while the theoretical speed of the U3 card can reach more than 30MB/s. If a UHS-II card is inserted into a device that only supports UHS-I, then the line of contacts below the card will not be used at all, so the card can only play UHS-I speed, not UHS-II speed.
SanDisk Ultra TF card
Another grade mark that is more common on the TF card is the grade mark that starts with the letter A. The A1 and A2 standard systems are a new system standard announced by the SD Card Association in 2017, which is used to identify the stable speed that the SD card can achieve when running the APP in the smartphone. A1 stands for Application Performance Class 1, and its minimum sequential read and write speed can reach 10 MB/s, random read can reach 1500 read IOPS, and random write can reach 500 write IOPS. The A2 level has a minimum sequential read and write speed of 10MB/s, but it can reach 4000 read IOPS for random reads and 2000 write IOPS for random writes.
List of SD card speed classes
In order to facilitate the comparison of your old iron, I found this speed level corresponding table on Baidu, which is convenient for everyone to compare, so that the speed of various specifications of memory cards can be seen at a glance!
It's more important to be clear about your needs
After understanding the various parameters and specifications, you must be clear about your own needs, and only by knowing what you need can you buy the most worthy products, isn't it
Nikon ZF
For example, my strategy of selecting a memory card for Nikon ZF, my demand for this camera is to double repair video and pictures, but in view of the fact that my computer will have some difficulty in post-processing 4K60 materials, and ZF will shoot 4K30 materials will have the blessing of 6K super-collection, so I choose this SD card as long as it meets the speed needs of 4K30, Lexar's 1800X is a V60 high-speed card, it is more than enough to cope with this specification, and at the same time, because the size of the 4K material is still very touching, The capacity of 128g is just needed, considering that the 128 card is much more cost-effective than the 256G card, so I chose the V60 level 128G card.
Primary and standby cards
Although ZF only has one SD card slot, it is also very necessary to add a cost-effective backup card, after all, the storage space is limited, and if one is not enough and there is no spare card when shooting outside, it will be embarrassing to get home. At the moment when the price of memory cards is generally rising, after a round of comparison, I found that this Tianshuo V60 card is the most cost-effective choice in the same price range! The five-year warranty can also make you feel at ease, so that you can rest assured!
TOPSSD High Quality SD Card _H1 Professional Image Memory Card UHS-II Dual Core V60 High Speed Storage v60 SD Card 128GB
PS: Tianshuo's card is really cost-effective! I've used this one for more than a year and haven't encountered any problems, so I can rest assured that I can rush ~

PS: Although Lexar's 1800X card is expensive, it is guaranteed by big brands, and the budget is enough, no problem!
Nikon ZFC
And for my secondary machine ZFC,A 20 million pixel apsc body, its requirements for storage speed are not so high,At the same time, its maximum video specifications are only4k30,And there is no NLOG,If you use it to shoot video, then its requirements for memory cards are much lower than full-frame models like ZF。
The card speed of the V30 is sufficient
Under this demand, the V30's card speed can fully meet the demand! The same 128G memory card, the price can be nearly half cheaper, SanDisk's V30 card is of excellent quality, the price is also appropriate, the cost performance is very outstanding, you can consider it!
PS: This is my old SanDisk extreme pro card, and now the new 128G has upgraded the maximum read speed, but the speed level remains the same, it is still V30. If you don't shoot videos much, then Samsung's small white card can also be considered~
SAMSUNG 128GBSD memory card, EVO camera card, U3V30 high-speed digital camera memory card, support DSLR camera, 4K video reading speed, 130MB/s
PS: My Samsung little white card was also purchased two years ago, and now the price of the new small white card is less than 100 yuan, and the reading speed has also been improved, and the cost performance is very high!
A more cost-effective, low-capacity card
If you don't shoot videos at all, the 64G capacity memory card is also a good choice, like my Ricoh GR3 usually only shoots in JPG format, the continuous shooting speed of the little guy is also very touching, I almost don't use it for heavy shooting, then the 32g card is very sufficient, and the selection of cards is simple and saves a lot of money under the promotion of this demand.
闪迪（SanDisk）64GBSD内存卡4KV30U3C10相机存储卡读速200MB/s写速90MB/s微单/单反相机内存卡
PS: This extreme pro card from SanDisk was also bought a few years ago, and now the new version of the card is nominally 200MB/s read speed, and the actual write speed is the same as the old card 95MB/s.

PS: The price of SanDisk's low-profile u1c10 entry card is even more beautiful, for friends who do not take continuous shots and have pure picture needs, the cost performance of this card is directly full!
金士顿（Kingston）64GBSD存储卡U3V30相机内存卡高速sd卡大卡4K超高清拍摄读速170MB/s
PS: Since Toshiba's memory card is indeed relatively old, a certain east can no longer find an official sales channel, it is recommended that you can take a look at Kingston, Samsung and other major manufacturers' products, v30's 64G cards are all good products within 100 yuan, and the cost performance is very high!
v60 TF card
My ZF also has a card slot is TF card,I chose this moving speed 400G high-speed card to make it a backup card,Usually when taking pictures, this tf card is responsible for storing jpg format pictures,It can also be used as a good helper for backing up materials when shooting videos,The main recording still relies on SD card。
移速（MOVESPEED）400GBTF（MicroSD）内存卡高速V60相机存储卡手机平板游戏机行车记录仪/监控摄像头
PS: The speed of the card is very cost-effective, I heard that this 400g card is from the 512g card lock bad area, but I think it, as a spare card cost performance is very important, as long as it is durable ~ At present, this card has been in service for two months, there is no problem ~
TF memory card
In addition to photography needs, there are also light use needs such as dash cams, switch game consoles, etc., these cards on hand can just cover these use scenarios, let's start with the dash cam!
闪迪（SanDisk）128GBTF（MicroSD）内存卡A1U1C10至尊高速移动版存储卡读速140MB/s手机平板游戏机内存卡
PS: This SanDisk 128G a1 card is very suitable for all kinds of dash cams or home cameras, and the nominal reading speed of 140MB/s is also enough to cope with the 4K video needs of various dash cams, which can be described as a cost-effective choice for large manufacturers~

PS: For the switch, the durability of the TF card is the most important, and I was full of apprehension when I bought the card last year, but after a year of stable service, I am also down-to-earth, anyway, it is a toss, and I have to play hard~
雷克沙（Lexar）512GBTF（MicroSD）存储卡U3V30A2读速160MB/s手机平板switch内存卡（PLAY）
PS: Lexar's 512G a2 card is also very cost-effective, the measured speed is similar to the stability and movement speed of the card, but after all, the capacity is larger112GB, you can store several more games on the switch, the price is only 50 yuan more expensive, and it is also cost-effective!
Transcend's TF card
This Transcend TF card is a Sophie pro3 that I bought for Microsoft many years ago for expansion, and I have served it diligently for several years, and it is still available today, but after round after round of price increases, Transcend's cost-effective advantage has become not so high
Transcend High Speed Memory CardCanon, Sony Nikon, DSLR, Mirrorless Camera, Memory Card, Mobile Car DVR, Security Surveillance, GoPro4K Video Recorder, Rugged High Speed TF Card, 100MB/S64GB
ROG handheld
There is also a special TF card use, that is, to expand the capacity of the winhandheld! Just like my ROG win handheld computer, it has a TF card slot, for Lao Tie who doesn't want to trouble tossing and replacing the hard disk, matching it with a TF card has become a compromise solution for "saving the country with a curve".
闪迪(SanDisk)1TBTF内存卡A2U3V304K游戏存储卡读速190MB/s写速130MB/s游戏不卡顿游戏机掌机专用卡
PS: SanDisk has specially launched an ultra-high-speed TF card for gaming needs, but the price is also very touching......
ROG handheld memory card connector
The reason why we must emphasize that the WIN handheld is equipped with TF cards to consider durable cards, the main reason is that their card slots are basically set up in the core component area with serious heat, and in actual use, TF cards will inevitably have to endure the torturous high temperature baptism, if it is not a card with high durability, it is easy to be lost

PS: Zhizhi, that is, the long-lasting son also has a durable TF card for sale, although the price is high, but the durability is very strong, it is worth considering.
To sum up
Although there are a variety of memory card products on the market, as long as you understand the difference between specifications and clarify your own needs, it is no problem to find the one that suits you among the complex products!
Large collection of SD cards
PS: There is no pre-sale routine for 618 this year, and it will start directly on May 20th! Do your homework, just keep the shopping cart and place an order directly~ There are fewer routines and more affordable, which is worthy of praise
The above is my 618 memory card strategy~ If you think what I said is not bad, then please like and collect it more and pay attention to support a wave~ Your support is the driving force for me to continue to update~ Bixin
