SanDisk has launched a new 512GB microSD Express card aimed at creators, adventurers, and gamers who need high-speed, durable storage in a compact format. It is priced at 1499 yuan on JD.com and $119.99 on Amazon.

SanDisk 512GB microSD Express Specifications

The card uses PCIe 3.1 NVMe technology to deliver read speeds of up to 880MB/s. The 512GB and 256GB models reach write speeds of up to 650MB/s with sustained write speeds of 210MB/s.

The 128GB model offers the same maximum read speed but writes at up to 480MB/s, with a sustained rate of 100MB/s. These speeds place it close to mainstream portable SSDs and far ahead of standard microSD UHS-I cards.

The card supports 5.3K and 4K video recording, high-resolution RAW photography, and slow-motion footage. It works with PCIe NVMe and is backward compatible with microSD UHS-I devices, covering Android smartphones, tablets, drones, action cameras, laptops, and handheld gaming consoles. It is also compatible with the Nintendo Switch 2.

The card is resistant to water, extreme temperatures, humidity, drops, shocks, magnetic interference, X-rays, and abrasion. SanDisk includes its ThermAdapt technology, which uses a specially designed shell and controller with dynamic thermal management to prevent overheating during heavy workloads.

When paired with the SanDisk Pro-Reader SD Express dual-slot card reader, the card reduces transfer times significantly. Transfers of a 60-minute 4K30 video can be up to 2.8 minutes faster, while 2,000 10MP RAW images move up to 2.9 minutes faster. Under optimal conditions, a two-hour HD movie transfers in less than 3.5 seconds

The card comes with a lifetime limited warranty and a two-year subscription to SanDisk’s RescuePro Deluxe file recovery service. It measures 14.99mm by 10.92mm by 1.02mm and operates in temperatures from -25°C to 85°C, with storage tolerance from -40°C to 85°C.

The post SanDisk launches 512GB microSD Express card with SSD-level speeds & Nintendo Switch 2 support appeared first on Gizmochina.

Last week, Samsung launched the T7 Shield, its most durable portable SSD. Now the company has unveiled another durability-focused product known as the Samsung PRO Endurance microSD card. This latest card is designed to be used in devices like security cameras and doorbell cameras which require continuous capture and playback.

Devices like Security cameras continuously record and write data to the card. The regular memory cards cannot withstand this process for long. Hence, they need to be replaced every couple of years. This is not the case with the Samsung PRO Endurance, this microSD card is exclusively designed to meet the demand for continuous video recording.

Samsung claims that its new memory card can last up to 16 years (140,160 hours) of continuous recording time. Compared to the previous speed-focused cards, PRO Endurance series memory cards can last up to 33x longer, saving recurrent replacement costs and providing better reliability for continuous video recording.

The new microSD card is designed to provide stable performance even when subjected to extreme situations. The card comes with Samsung’s improved “six-proof durability” which makes it wear out and drop-proof and resistant to water, magnets, X-rays, and extreme temperatures.

The card measures 15 x 11 x 1mm and weighs approximately 0.25g. It comes with a write speed of up to 40Mb/s and a read speed of up to 100Mb/s. The operating temperature of the card is -25°C to 85°C. The new Pro endurance microSD card has a Class 10 rating, along with UHS-III and V30 classifications for video speeds. The card is also capable of handling Full HD and even 4K video recordings.

Samsung Pro Endurance microSD cards come in 32GB, 64GB, 128GB, and 256GB versions. The 32GB version is priced at $10.99, whereas the 64GB version costs $14.99. The 128GB and 256GB versions of the memory card cost $27.99 and $54.99, respectively. The card is available for purchase through Amazon.

OnePlus made the new OnePlus 3 official yesterday and the company seems to have taken a safe route this time, giving users almost everything that they would expect on a new flagship phone without any surprises. However, there were some questions that we needed answers like what exactly is an Optic AMOLED display and why did the company decide to do away with the memory card slot on the device. Today, at the Reddit AMA, OnePlus’s CEO Carl Pei and a bunch of other staff answered these questions, which gives us a good idea about a few decisions taken by the company regarding the new OnePlus 3.

I have compiled the major questions asked and their answers. So, here’s the highlight of the AMA at Reddit.

Why reduce the battery capacity on the OnePlus 3?

OnePlus is of the opinion that 3000mAh will get you throughout the day and dash charge comes in handy. You could get around 7 hours+ of 2K video on medium screen brightness with 30 minutes of charging. Further, the use of Optic AMOLED panel and the efficient Snapdragon 820 will ensure that the OnePlus 3 will last throughout the day.

What is this Optic AMOLED Display?

OnePlus has used current gen. Super AMOLED panels and added their take on contrast and color temperature making it or at least trying to make it true to life. Carl says this also works well outdoors, in bright conditions.

Why stick with 1080p resolution on the OP3?

Because anything over 1080p is only beneficial for VR, and you spend more than 95% of your time outside of VR. Plus, having a resolution more than 1080p has many drawbacks.

Will rooting OnePlus 3 void warranty?

Like all OnePlus devices, rooting won’t void warranty.

When will OnePlus release kernel for the OnePlus 3?

It’s already released!

Does OnePlus 3 support Android Pay?

Yes, it fully supports Android Pay.

Any plans for a 4GB RAM variant?

No. OnePlus 3 is only available in 6GB RAM version.

Why does OnePlus 3 not have a MicroSD card slot?

MicroSD card slots slow down your storage as compared to the inbuilt ROM which is super fast UFS 2.0. Plus, it makes the phone bulkier. Hence, no MicroSD and 64GB ROM as standard.

When can we buy the soft gold version?

Soon, but no date mentioned yet.

Why remove Laser Focus from OnePlus 3?

Carl said that PDAF is better because LAF only works at <40cm.

Any more variants of the OnePlus 3, like smaller storage version?

Nope. Just the soft gold color version that will be released soon.

What’s the DAC used inside the OnePlus 3?

Standard one that comes with Qualcomm SD820 chip.

Why price the OnePlus 3 at 399 EUR which is higher than 399 USD in US?

Because of taxes and transportation costs, the price is higher in EU.

That pretty much sums up the major questions asked at the AMA on Reddit. If you want to check it out, click here.
