Lexar Launches 512 GB microSD Card with A2 App Performance Spec

Lexar this past week introduced its new family of A2-class microSD cards, the Lexar High-Performance 633x A2. Supporting the highest Application Performance class, the new microSD card is designed in particular for smartphones that need additional storage space for applications. Overall the Lexar High-Performance 633x family of microSD cards is fairly diverse; the cards range in capacity from 16 GB to 512 GB in capacity, and not all of the cards meet an App Performance class standard. Indeed, only the new 512 GB card meets the A2 class standard, while the medium-sized cards are A1 class.

Under the hood, all the cards use the UHS-I bus and are rated for 95 MB/s – 100 MB/s reads as well as 45 MB/s – 70 MB/s writes. Most of the cards in the lineup support the Video Speed Class 30 spec, therefore offering at least 30 MB/s sequential write speeds. As for operating temperature range, it is pretty standard: from 0° to 70° C (32°F to 158°F), which is good enough for everyone except those using specialized devices to work in extreme conditions.

The key feature of the Lexar High-Performance 633x range is of course support for A1 and A2 App Performance specifications, for use with Android phones that need more space for applications. While A1 cards are pretty common these days, A2 cards are still rare partly because they require a more sophisticated (and expensive) controller and partly because not all of their features can be experienced on commonly available hosts.

As we've mentioned before, A2-badged microSD cards mandate a random performance of at least 4000 read IOPS and 2000 write IOPS (vs. 1500/500 read/write IOPS mandated by the A1). Meanwhile, A2-compliant controllers have to support such functions as command queuing (with a minimum depth queue of 2 and a maximum depth queue of 32) to optimize random read performance, caching to hit write performance targets, as well as self-maintenance capabilities. Though to get the most out of an A2 card, the host also needs to support command queuing to guarantee the device's read performance.

Samsung will soon launch a 512 GB microSD card

As some manufacturers get rid of the headphone jack and microSD card slot, Samsung continues to include both of them in its smartphone lineup, particularly its flagship devices. To the delight of many users who prefer function over form, Samsung didn’t change its strategy for the recently launched Galaxy Note 9.

In fact, even though the latest Note smartphone comes with twice the internal storage of its predecessor, it still retained the microSD slot. Most phones with a memory slot often tout support for cards up to 2 TB, but this theoretical limit doesn’t mean anything when there aren’t a lot of high-capacity microSD cards in the market. Samsung will soon be joining the list of a few companies that have launched 512GB microSD cards.

512GB Samsung microSD card coming soon

During Samsung’s Unpacked event yesterday, Drew Blackard, Senior Director of Product Marketing, mentioning in passing that Samsung would soon launch a 512 GB microSD card. When paired with the 512 GB internal storage of the topmost Galaxy Note 9 variant, you will get 1 TB of storage in your pocket. You can hear him talk about it during Samsung’s Unpacked event yesterday here.

Currently, a 256 GB microSD card is the most you can affordably get for your smartphones. There are only a few companies that have 512GB microSDs card on the market right now. SanDisk is selling one, so are PNY and Integral. The cards cost over $300 and that’s likely going to be the price point for Samsung’s upcoming 512GB microSD card as well.


Samsung’s 512GB microSD is a huge storage upgrade that’s cheaper than ever

Samsung’s Evo Select 512GB microSD card is currently $99.99 at Amazon, which is its lowest price yet. If you own a Nintendo Switch — or if your smartphone, tablet, or action camera features a microSD port — this is a relatively affordable route to take if you want a big upgrade to your expandable storage.

Up against SanDisk’s popular 400GB microSD card, this 512GB Samsung card has the obvious advantage when it comes to storage capacity. It also offers UHS Class 3 speeds compared to UHS Class 1 on the SanDisk model. The SD Association states that this distinction is noteworthy, but it will mostly impact those who record video. Though, if you plan to use Samsung’s microSD card for both gaming and recording video, it’s good to know that it can perform both functions well. This microSD card comes bundled with an SD adapter, which is handy for checking out files if your computer, like most Mac laptops today, no longer has a card slot.

Despite its advantages, it’s tough to ignore that SanDisk’s 400GB microSD card is now just $63.57. But if you have $100 to spend and are set on adding a half-terabyte of storage to your device, your money can stretch a little further today.


PNY introduces a 512GB microSD card for $349.99

Earlier in the year, Integral Memory introduced the world's first 512GB microSD card (which unfortunately isn't sold stateside). PNY is showing off the second 512GB microSD, the PNY Elite 512GB, at Computex 2018, and the card will run you $349.99 when it becomes available.

Meet the current highest capacity micro SD card in the world! The PNY Elite 512GB. Come see it for yourself, at Computex 2018. #pny512gb #pnyusa #pnymicrosd.

The PNY Elite 512GB complies with Class 10 and U1 standards, which means it has a minimum sequential write speed of 10MB/s. PNY says that the card can handle transfer speeds of up to 90MB/s, which is 10MB/s more than Integral Memory's max. For reference on just how much space 512GB is, the Elite 512GB can store over 100,000 18MP photos, over 80 hours of 1080p video, or up to 100,000 songs.

The card is worth what this no-name tablet and Galaxy S4 cost several times over.

There's no word on availability yet, but PNY has priced the card at $349.99 - on par with the Integral Memory 512GB card, but a lot more than a SanDisk 400GB microSD at $194.60. A limited lifetime warranty is included. We're looking forward to seeing this thing show up online, and hopefully, drop in price pretty soon.


Integral Memory’s new 512GB microSD card is the biggest microSD card yet

There’s a new king of the microSD card: Integral Memory’s 512GB microSD card, which packs a record breaking full half-terabyte of storage into the diminutive card format. You definitely should try not to lose it.

The previous record holder — SanDisk’s now paltry 400GB card — is still a bit faster at 100MB/s, whereas Integral Memory’s new 512GB behemoth tops out at a maximum speed of 80MB/s. The new 512GB microSD card is also classified as an SDXC UHS-I U1 card (i.e., it has a minimum write speed of 10MB/s) and meets the V10 standard for video transfer rates, so it’s designed to capture full HD video off cameras.

No price was given, but it’s almost guaranteed to be expensive when in launches sometime in February.


512GB MicroSD Card Coming from Microdia -- Someday

Updated on 8-30-2015 by Jeremy Kaplan: Revised and updated to reflect lack of availability of the product, including comments from the company and growing concern among eager customers.

Microdia plans to take MicroSD storage capacity to the absolute extreme with its new Xtra Elite card, which crams 512GB into a normal-sized MicroSDXC card — but when exactly will the tiny giant actually be released?

Sandisk announced a 200GB microSD card in March, a capacity that was quite impressive — it still is, to be fair. But it seems tiny when you look at it next to the half a terabyte of storage purportedly in Microdia’s card, which was discovered by CNET on the show floor of Computex. The SDXC specification allows cards to store up to 2TB, but this 512GB card is the largest we’ve heard of so far. Of course, SanDisk won’t be far behind, as the company has previously released a full-sized 512GB SD card.

The team at Microdia didn’t have an actual working sample on the show floor, however, so eager professional photographers were forced to take the company at its word regarding the giant card. The card was set for release in July; is it available today, a full month after Microdia promised to deliver it?

“Technically is YES,” Michael Anderson, Vice President of New Product Development, told Digital Trends. “But commercially, we are pushing out our 256GB microSD (uSD) Cards first and hope to clear all of our production inventory of 256GB uSD by end of the year.”

“Then we will promote 512GB accordingly, as else our 256GB uSD will be destroyed by our own 512uSD,” he explained.

Meanwhile frustration is mounting among photographers eager to get their hands on the biggest cards in town.

“I was very excited when I first heard about it. Now I feel this is all a sham.”

“I was very excited when I first heard about the 512gb card, “wrote Marcos Javier Soria on the company’s Facebook page. “But now I feel this is all a sham.”

“They don’t have any, just blowing in the wind to hype their own company’s name,” another person wrote.

The company responded to the criticism (sort of) on August 6, with a small note that the smaller 256GB cards were finally available: “Dear Everybody, our 256GB has been released. please msg me your email address and your location. Be quick limited stock available!”

Besides limited (if any) distribution, the card carries another red flag: a huge price tag. The $1,000 price point cited by CNET is just an estimate, and the final price could vary slightly, though that stab is likely to be in the right ballpark, making this card prohibitively expensive for the average shutterbug.

The Xtra Elite reportedly uses version 4.0 of the Secure Digital standard, which allows for data transfer speeds up to 300MBps. SD 4.0 also adds a second row of pins below the standard ones.

This card is clearly aimed at professional photographers who can stomach the large expense in exchange for not having to switch cards. It’s exciting for everyone, though, because like all new technology, the price will go down, and at some point the rest of us will be able to pick up huge MicroSD cards for reasonable prices.

Assuming Microdia ever releases the darn thing.
