U-disk SD card to become the next Blu-ray disc?

When it comes to mobile storage brands, who do you think of first? Kingston? Toshiba (TOSHIBA)? SanDisk? In fact, besides them, there is another brand that is not unfamiliar to professionals: Lexar.

Although Rexha may be a little strange to ordinary users. But their professional products have been quite outstanding in performance: 400 MB/s U disk (Reyksha P20), 300 MB/s SD card (2000X), 270 MB/s TF card (1800X), 540 MB/s CFST card (3600X)... There's also a huge modular card reader (Reyksha HR2)... It can be said that in the field of professional flash storage, the performance of Rexha can be "king"!

Not long ago, however, a news directly broke the hearts and worries of many users who loved Rexha: Rexha's parent company, Micron, a flash giant, suddenly announced that it would abandon Rexha's mobile media storage business and seek to sell it in whole or in part.

This means that we are likely to lose a top-notch mobile storage brand in the future; and don't forget that another industry giant, Flash, has not had a new product for a long time since it was acquired by Western Numbers, and has recently been involved in the wave of Toshiba's selling of its Flash Storage Factory, which is likely to hit production capacity (Flash and Toshiba Shared Factory). 。 By the way, Toshiba, as a core member of SD Association, can be said to be leading the change of SD card specifications, but now it has also fallen into a sales factory - it can be said that in a short period of time, consumers are facing the risk of "disappearing" at the same time of the three most outstanding brands of mobile storage devices in the industry.

This makes people want to ask: What exactly happened? So that the mobile storage industry suddenly "avalanche" - and all the best ones?

At the beginning of this year, when many "disks" shut down and contracted their businesses because of operational or regulatory risks, the author also thought that this would be a good thing for traditional physical memory manufacturers, but did not expect to go against their wishes. Is it because we are used to the "free" disk, and have lost interest in physical memory? From an economic point of view, this does not make sense, and it is more likely that there are better (or cheaper) alternatives.

Here's what it's all about: Yes, the "Universal" smartphone has eaten into the market of high-end mobile storage devices, after killing off the home card camera.

Moreover, like many mobile phones, the actual photographic effect can be better than low-end cameras. In fact, many flagship mobile phones have built-in storage schemes, both capacity and speed have surpassed U disk and memory card. Taking Samsung S8 + built-in UFS2.1 flash memory as an example, its capacity reaches 128GB, the actual reading speed reaches 760MB/s and the writing speed is 220. MB/s has gone far beyond today's top U-disk and crushed the newly released SD Association UHS-III specification (624MB/s) - the latter has not even been put on the market.

And this also explains why there are a large number of low and medium-end flash brands on the market, "group magic dance", located at the top of the industry, but several giants collectively "rush to the streets". Imagine that users using Samsung S8 and Apple's iPhone (even without supporting memory cards) no longer need to buy high-end U-disks or memory cards, and those who can't afford top-notch mobile phones can't afford top-notch other mobile storage devices. The only people left are tech geeks and photographers in need --- but the overall spending power of the minority group is too strong to support the revenue of the giants...

Of course, in the face of such a dilemma, relevant enterprises are not without "self-rescue" - for example, SD Association has frequently revised SD card related technical specifications in the past two years: first, it proposed "Video Speed Class" for video shooting, and then announced that it aimed at APP2SD technology (that is, supporting mobile phone to install APP to SD card).“ App Performance specification, followed by "LV" low voltage authentication, and the new bus speed UHS-III. All in all, we need to speed up, increase product classification, and improve compatibility with mobile devices.

However, imagine these logos appearing on the product at the same time - just like a disaster, how can ordinary consumers distinguish clearly? Even as a professional editor, I feel overwhelmed when I see SD Association's magnificent "specification evolution table", and I really don't know where they come from.

But do we say so much that mobile storage devices such as U disk, SD card and TF card will really disappear from our lives in the future? That's not necessarily true.

First of all, as mentioned earlier, despite the difficulties encountered by several giants, there are still a large number of second and third-tier manufacturers (such as Kingston) in the market, and their main consumers are enough to "support" the survival and development of manufacturers. Secondly, the demand of high-end consumers for high-performance mobile storage devices is still just needed in a short time, and if there is demand, there must be supply. So at least we don't have to worry about not buying high-quality and expensive flagship SD cards and CF cards.

However, if you want to know how to recover deleted files from flash drive, in the current era of continuous technological updating, leading enterprises suffer a setback, and the industry technical specifications lag behind the competition, which is not convenient enough for mass consumers. Such a scenario does make people feel familiar - will future mobile storage devices become the second "Blu-ray Disc"? Now it seems that it's really hard to say.
