Samsung 256GB SD Express microSD cards and 1TB EVO Plus and 1TB Pro Plus microSD cards. Samsung
One of the main advantages of some Android smartphones over the iPhone is the ability to expand storage using a microSD card. If you’re short on space, you pull out the SIM card tray, pop in one of those little storage cards, and off you go.
Whether it’s a smartphone, a video surveillance camera or a smartphone, microSD cards are omnipresent.
And now Samsung, one of the biggest players in storage, is taking microSD cards to the next level thanks to two new features that will make enthusiasts salivate.
Speed!
But, there is a but. And it’s very strange. Samsung may make the best microSD cards and yet users of Samsung smartphones… will not benefit from them. For what ? Because the company has no longer integrated a microSD card slot into its high-end smartphones since… 2020!
So, the first new thing is that the company now offers 256 GB SD Express microSD cards. And what sets them apart from all the other microSD cards currently available on the market?
Speed !
Up to 4 times faster
These SD Express microSD cards can reach sequential read speeds of 800 MB/s, which is 1.4 times faster than SATA SSDs and four times faster than previous generation UHS-1 storage media.
Since such speeds generate a lot of heat and microSD cards are usually placed in confined places, these SD Express microSD cards use Dynamic Thermal Guard (DTG) technology to keep temperatures at the right level and prevent overheating of the card. card, even when used for long periods of time.
The downside to this technology is that it controls temperatures by throttling the card’s performance, so actual speeds are likely to vary depending on device, usage type, and even ambient temperatures.
Another thing: Although SD Express microSD cards are backwards compatible with current microSD card sockets, to get these speeds you’ll need SD Express compatible devices, and right now those devices are few and far between.
Resistant up to -25°
Samsung also announced that it has begun mass production of 1TB UHS-1 microSD cards that use its 8th generation 1 terabit V-NAND technology. According to the technical sheet, this is a resistant card since, according to Samsung, this card can survive different situations:
- Immersion in salt water up to 1 meter deep for 72 hours.
- Operating temperatures from -25℃ to 85℃, and non-operating temperatures from -40℃ to 85℃.
- Passage through airport X-ray machines (up to 100 mGy).
- Exposure to magnetic fields equivalent to those. a high-field MRI scanner (up to 15,000 gauss)
- Falls up to 5 meters.
- Up to 10,000 passes in a microSD card reader
It’s incredible !
Samsung’s 256GB SD Express microSD card is expected to launch “later this year,” while the new 1TB microSD card is expected to arrive in the third quarter of 2024. Pricing for these two cards has yet to be announced. been communicated.
