SanDisk introduces the first 8TB SD and 4TB microSD cards

SanDisk has announced the introduction of the first 8TB SD cards and 4TB microSD cards, showcasing these products at the Future Memory Storage 2024 conference. These cards, branded under Western Digital's SanDisk label, are designed to meet the storage needs of modern devices such as smartphones, gaming consoles, drones, cameras, and laptops. They are classified as SDUC UHS-I cards, which offer theoretical transfer speeds of up to 104MB/s, sufficient for most photo and video applications. Currently, the largest commercially available SD and microSD cards are around 1.5TB, making the upcoming 4TB and 8TB cards significant advancements in storage capacity. The SD Ultra Capacity (SDUC) standard, established in 2018, theoretically allows for cards with capacities up to 128TB, although it may take time before such high-capacity cards become available.

- SanDisk is releasing the first 8TB SD and 4TB microSD cards.

- The cards are designed for various devices, including smartphones and cameras.

- They will have theoretical transfer speeds of up to 104MB/s.

- Current largest SD and microSD cards are about 1.5TB.

- The SDUC standard allows for future cards with capacities up to 128TB.

Its crazy my iPhone only has 128gb of storage. Its also crazy storing a file on in the cloud is typically $0.01 per gb/month (for R2 at least, iCloud is even more). Someone needs to figure out how to prevent submarket/subproduct price fixing from the major platforms.

I remember trying to explain to my grandparents how many individually addressable bits were in a 128MB SD card. To them the number was impossibly high.

I wish they were stay alive today, to see a 8TB MicroSD card. ;-(

I wonder what the limit is.

I still have a photo of myself holding a 256 MB micro SD card. I was in awe when I saw it.

maybe dumb question, but what accounts for SD card density improvements? what's the primary factory that allows fitting more and more memory? is it transistor shrinkage, like CPUs?

I'm not surprised to see only capacity and speed being mentioned, but nothing about reliability. I wonder what the endurance and retention is like. Possibly PLC flash? I remember reading that PLC wears out in less than 100 cycles per block, with retention measured in months or days(!) depending on temperature. These aren't SSDs so there's no expectation that they'll be powered on most of the time and can self-refresh.

At 104MB/s it would take over 10h to transfer 4TB, and likewise 20h to transfer 8TB.

I'd rather they offer 2TB SLC SD and 1TB SLC microSD cards at the same price, which they could if these were QLC.

You know what be great? If my phone had expandable storage.

I wonder if those micro-sd card are regular sd or sd-xc (the latter being way faster).

I need to ask around why SD have such a short lifespan, while SSD are just fine.

Suddenly those 64TB and uo nvme drives don't seem that absurd.

So now we're down to 1 card for a whole Stasi-worth of tracking: https://news.ycombinator.com/item?id=40058094

Now I wish there is an NAS that support SD Card.
