Analysis of the Global External Storage Market in Q3 of 2023

Huawei Overtakes Dell in All-Flash array by Q3

Global External Storage Market in Q3 of 2023

In the past, I used to prefer using images of beautiful ladies on the cover because most of our readers were male. Today, let’s change the style and cater for our female readers.

Over the weekend, I spent some time on the latest market data for external storage in third 2023 quarter, which is released by Gartner. Now I’m sharing my analysis with everyone.
Firstly, let’s take a closer look at the global External Controller-Based (ECB) storage market in 3Q23.

We observed that global ECB storage in Q3 had declined by 12.8%, it was a challenging situation. Refer to the data, leader Dell had declined by 27.6%, with a market share of 23.1% only. On the one hand, it should be a lowest record for Dell year-on-year. On the other hand, Huawei had grown by 7%, achieving a market share exceeding 20% for the first time. It was possibly the best performance so far. Upon closer inspection, the Q3 sales of Huawei in China market experienced a slight decline. However, its overseas markets were generally growing, maintaining a positive growing trend. Huawei has firmly secured the second place, and left NetApp far behind. Moreover, it is starting to threaten Dell’s dominant position.

According to the data from Solid State Arrays (SSA) or an all-flash array, the global market has declined by 3.5% in 3Q23. However, Huawei had been increasing by one-third, while Dell declined by 26%. This marks history that Huawei surpasses Dell by the first time, and hits the first place of all-flash Array by 3Q23.

Of course, the most valuable reference is to check the overall situation from Q1 to Q3 in 2023

Comparing to the first three quarters of the 2023, i.e., 3Q23YTD, global ECB storage declined by 9%. Dell maintained the top spot but declined by 14%. Meanwhile, Huawei caught its second place, growing by 11%, with a market share exceeding 15%.

If we only focused on SSA all-flash, there was a global decline of 2.5%. Despite Dell was declining, its first position remains relatively stable. NetApp, Huawei, and Pure Storage all had shares around 15%, statistically we considered thaty they tied for second. Therefore, the ultimate winner for the year will depend on the fourth quarter.

Now let’s explore into the performance of storage based on different purposes.

In terms of primary storage, there was an overall decline of 10.7%. Dell, Huawei, and NetApp are the top three.

For secondary storage, there was a slight decline of 0.3%. Dell and Huawei are taking main share, both of them exceed 20%.

In the backup and recovery market, there was a decline of 11.8%. Dell maintains an absolute monopoly with a market share of 68.8%. Huawei is growing rapidly, but its share is close to 9%.

Finally, let’s compare the situations in China with United States.

In the first three quarters of 2023, the ECB storage in US had declined by 14.4%, indicating a terrible situation. Dell’s market share was 38%. Pure Storage surpassed NetApp and took the second place.

In China, there was also facing a decline of 5.4%. However, Huawei maintained growth, its market share had increased to 48.7%.

Suddenly China’s SSA market also declined by 3.6%. Nevertheless, Huawei continued to rise in a downward trend, the market share was reaching 56.4%.


Based on the Q3 data, Huawei is maintaining steady growth while Dell is experiencing a significant decline. If this trend continues, it’s highly possible for Huawei to take the first place of global storage one day. However, my preliminary judgment is that it might not happen in the short term. The U.S. stock market is currently going well, and economic indicators are favorable. The storage market might rebound next year. Nevertheless, Huawei’s achievement of acquiring the top spot for all-flash in Q3 has brought pressure to Dell. Even though Huawei cannot enter the largest storage market in US, its share in storage market continues to grow steadily. Regardless of the changes in the external economic environment, it is not surprised that Huawei may far beyond Dell one day.

Is mobile phone bulk mico SD cards expansion necessary?

The new mobile phones in 2022 supporting external storage were few, such as the Sony Xperia 1 IV and Huawei Mate Xs 2. These new models support to use bulk Micro SD cards. I’m not sure when mobile phones started progressively losing the ability to support such expansion. Ordinary consumers can only purchase phones with higher capacity if they wish to increase their memory space. Is it true that we don’t require bulk Micro SD cards expansion? A questionnaire study on memory card expansion for mobile phones gets start recently.

Bulk SD Card

In the first, users were asked how important SD memory card expansion is to them, and we can see that 45% of the respondents said it was “very good but not very significant”. And nearly 40% said: “I will not buy a mobile phone without SD memory card expansion.” About 15% of the respondents selected “I don’t need it”

How important is SD memory card expansion to you?

In the second poll question, “How much storage is in use on your mobile phone right now?” , 128GB to 256GB accounts for up to 35.58% of the respondents, and 64GB to 128GB is the second-largest group. Those who have more than 256GB make up the third group, and the remainder is in smaller proportions.

how much storage is in use on your phone right now?

What is your phone’s storage capacity like?

Manufacturers of mobile phones are gradually discontinuing SD memory card expansion. On the one hand, each additional hardware on phone will raise its price and weight due to the cost. On the other hand, supporting SD memory card expansion will restrict sales of versions in high capacity. Another reason is that the read and write speeds of SD memory cards are very slow. Even the fastest SD memory cards in the market only have one-tenth of those of today’s mobile phones. Comparing to some latest phones, the speed of storage cards is even slower than that. The user experience will suffer in such a circumstance. As a result, manufacturers of mobile phones have every right to control the weight issue. The solution is not to use SD memory card as expansion.

The following are some of the user comments:

Comment 1

The speed of the mobile phone is not the reason for missing SD card slot. It is entirely a matter of price! When a domestic mobile phone increases to 128G, the price gets extra 300 yuan. While buying a 160MB/S 128G SD card, it costs only a few dozen yuan. It is clear that including a SD card slot, the net profit will get 200 yuan less. It all depends on the pricing, mobile phone suppliers will not care if customers desire high capacity or not. Invest less money with a phone with less memory. People expect additional phone storage when take pictures and videos. Also, WeChat images and videos take up a lot of memory. The 128G smartphone is insufficient! Therefore, internet users should avoid from the tricks and not purchase a mobile phone with a large capacity.

Comment 2

Mobile phone memory is expanding. Furthermore, chip updates and replacements are taking longer, and users save more content in mobile phones than ever before. When you switch phones, it takes hours for transferring more than 100 GB of content to the new phone. Then you need to spend hours on uploading and downloading data. That is just a phone of around 100 GB. How will you manage a smartphone that has larger storage than 500 GB and 1 TB in the future? The data in mobile phone is not 100% safe, you may accidently lose it or suffer damage. Therefore, it is necessary to get a backup on memory. In fact, memory cards work quite fine. You can complete this process in a minute when you replace the memory card.

Comment 3

I enjoy listening to songs, and I need to download music tracks. I never make a phone purchase if there is no memory card, as the space is not enough.

Comment 4

The availability of a memory card is practical. The data may be disappearing if the mobile device gets breaks. Some people say that you can store your data in online disk. However, there is a download speed limit of the network if you are not a member.

Comment 5

Type-c connector is gradually replacing old USB port. Also, the detachable battery has altered to an integrated battery. You may barely find headphone jack in new phones, and only the charging port is available. In this way, it is convenient for selling blue tooth headphones. Additionally, the universal charger is no longer available, while the power banks are getting popular. It is a revolution of phones, why we still need keep micro-SD slot for storage?

Comment 6

Using an SD card has two main advantages. 1. Typically, the data will not get damage if you store it in card, it is a great protection in case the phone develops a problem. Moreover, you won’t be hesitant to reinstall the operating system after simply taking out the card. Second, you can simply change the card if you swift to another machine. Otherwise, how can you transfer anything 120G from the old phone to the new phone?

Comment 7

The bulk SD cards are in perfect working order. People love storing all important pictures and videos in the phone’s memory. While all unimportant music videos, TV shows and movies are stored on the SD card. If there isn’t an SD card, your phone is insufficient. And you’ll have to get a new one. This is how producers of mobile phones might generate revenue.

Comment 8

I like to take pictures, therefore I consider whether an SD card is available for a mobile phone. The storage of a mobile phone itself may not have enough room for the thousands of images, memory cards are the best solution. I was wondering if the SD card of the mobile phone can be exit and load with one key.

How ultrasonic flowmeter works with bulk SD cards

An optional built-in mass data memory for the TDS series of ultrasonic flow meters, these Bulk SD cards, which are developed by the Memory Range Technology Co. Ltd. And then it can automatically record the text-format data output by the flow meters on their internal serial bus.


  1. The principle of operation
  2. The run core
  3. The flow meter settings

The principle of operation

Without opening the flow meter enclosure or removing the memory card, on the contrary, a user can still use the USB connector to copy the data file directly to the computer for further processing.

The MCU on this storage will automatically create a folder named LCEMB on the blank SD. Furthermore, the received data will be completely saved to the 0001.TXT file under the folder. A new TXT file, such as 0002.TXT, 0003.TXT, or 0004.TXT, computer will create them every time. Also, it is turning on or every 24 hours if the 0001.TXT file already exists on the bulk SD cards. Therefore, original files will not be overwritten. Instead, the newly generated file will be immediately updating with the data to be stored. Obviously consumers don’t need to be concerned that the TXT file’s size will prevent them from opening it.

The run core

Generally speaking the memory is speedier and more stable since it uses an industrial-grade 32-bit ARM series high-performance embedded processor. In addition, it can support a high-speed TF card with a capacity as large as 32G and completely support the user’s long-term use.

What’s more, the file system uses a special dynamic memory allocation algorithm to control memory consumption and release in order to improve data transmission efficiency, prevent data loss, support data storage rates of up to 14K bytes/second, and guarantee that no byte is lost over the course of prolonged operation.

The built-in memory card has a self-locking card holder as well as shockproof. On the other hand, data loss caused by unintentional poor contact between the memory card and the card holder can avoid it. And when there is no memory card or the memory card has poor contact, a buzzer will immediately sound a warning. When the memory card cannot be detected or is full, the warning will also sound eventually.

At first the memory controls a U disk and enables data copying from a USB. Secondly there is no need to install drivers because it includes a high-speed USB 2.0 interface with automated USB recognition. For instance, the power supply needs to be off before using a USB to copy data files. The memory cannot be powered simultaneously by the flow meter power source and the USB power supply.

In a word, the flow meter power supply is used by the card when it functions, negating the need for an external power source.

In order to prevent the data from being printed out simultaneously when a thermal printer is connecting to the bus, a switch to manage the printer’s power must be included.

In order to make sure the SD card work functionally, please follow the below configurations:

  1. Use the M50 menu to store the content you need.
  2. Use the M51 menu to choose when to start saving, how often to save, and how many times to save. Enter **:**:** for the start time of saving. When the number of storage cycles is entered as 9999, data storage is possible indefinitely.
  3. Sending the flow meter’s data to the “internal serial bus” , you need to choose it in the M52 menu.
Solid State Memory Chip

The development of solid state memory chip

Major memory chip manufacturer Micron recently declared that scale production of its 232-layer NAND flash memory chip had begun. The solid-state memory chip in question is the first in the world to have more than 200 layers.
