Western Digital Introduces 4 TB microSDUC, 8 TB SDUC, and 16 TB External SSDs
Western Digital's BiCS8 218-layer 3D NAND is being put to good use in a wide range of client and enterprise platforms, including WD's upcoming Gen 5 client SSDs and 128 TB-class datacenter SSD. On the external storage front, the company demonstrated four different products: for card-based media, 4 TB microSDUC and 8 TB SDUC cards with UHS-I speeds, and on the portable SSD front we had two 16 TB drives. One will be a SanDisk Desk Drive with external power, and the other in the SanDisk Extreme Pro housing with a lanyard opening in the case.
All of these are using BiCS8 QLC NAND, though I did hear booth talk (as I was taking leave) that they were not supposed to divulge the use of QLC in these products. The 4 TB microSDUC and 8 TB SDUC cards are rated for UHS-I speeds. They are being marketed under the SanDisk Ultra branding.
The SanDisk Desk Drive is an external SSD with a 18W power adapter, and it has been in the market for a few months now. Initially launched in capacities up to 8 TB, Western Digital had promised a 16 TB version before the end of the year. It appears that the product is coming to retail quite soon. One aspect to note is that this drive has been using TLC for the SKUs that are currently in the market, so it appears unlikely that the 16 TB version would be QLC. The units (at least up to the 8 TB capacity point) come with two SN850XE drives. Given the recent introduction of the 8 TB SN850X, an 'E' version with tweaked firmware is likely to be present in the 16 TB Desk Drive.
The 16 TB portable SSD in the SanDisk Extreme housing was a technology demonstration. It is definitely the highest capacity bus-powered portable SSD demonstrated by any vendor at any trade show thus far. Given the 16 TB Desk Drive's imminent market introduction, it is just a matter of time before the technology demonstration of the bus-powered version becomes a retail reality.

SK hynix Reports That 2025 HBM Memory Supply Has Nearly Sold Out 
Demand for high-performance processors for AI training is skyrocketing, and consequently so is the demand for the components that go into these processors. So much so that SK hynix this week is very publicly announcing that the company's high-bandwidth memory (HBM) production capacity has already sold out for the rest of 2024, and even most of 2025 has already sold out as well.
SK hynix currently produces various types of HBM memory for customers like Amazon, AMD, Facebook, Google (Broadcom), Intel, Microsoft, and, of course, NVIDIA. The latter is an especially prolific consumer of HBM3 and HBM3E memory for its H100/H200/GH200 accelerators, as NVIDIA is also working to fill what remains an insatiable (and unmet) demand for its accelerators.
As a result, HBM memory orders, which are already placed months in advance, are now backlogging well into 2025 as chip vendors look to secure supplies of the memory stacks critical to their success.
This has made SK hynix the secnd HBM memory vendor in recent months to announce that they've sold out into 2025, following an earlier announcement from Micron regarding its HBM3E production. But of the two announcements, SK hynix's is arguably the most significant yet, as the South Korean firm's HBM production capacity is far greater than Micron's. So while things were merely "interesting" with the smallest of the Big Three memory manufacturers being sold out into 2025, things are taking a more concerning (and constrained) outlook now that SK hynix is as well.
SK hynix currently controls roughly 46% - 49% of HBM market, and its share is not expected to drop significantly in 2025, according to market tracking firm TrendForce. By contrast, Micron's share on HBM memory market is between 4% and 6%. Since HBM supply of both companies is sold out through the most of 2025, we're likely looking at a scenario where over 50% of the industry's total HBM3/HBM3E supply for the coming quarters is already sold out.
This leaves Samsung as the only member of the group not to comment on HBM demand so far. Though with memory being a highly fungible commodity product, it would be surprising if Samsung wasn't facing similar demand. And, ultimately, all of this is pointing towards the indusry entering an HBM3 memory shortage.
Separately, SK hynix said that it is sampling 12-Hi 36GB HBM3E stacks with customers and will begin volume shipments in the third quarter.
