- ‘Sandisk 2.0’ with the objective of higher income from investors, ssds of greater capacity faster and more capacity
- 128TB Data Center Ultraqlc SSD launching at the end of this year
- Sandisk plans 256TB SSD next year, and a 1pb model in the near future
Western Digital announced plans to separate their HDD and Flash businesses in 2023 and began the process in October 2024.
In the future, WD will focus on the side of the hard drive and platforms, while Sandisk will concentrate on flash technology products, including SSDs, memory cards and USB Flash units.
Sandisk recently held a session of the Investor Day entitled “Sandisk 2.0” to emphasize this new business iteration. The company explained that it focuses on generating greater returns and improving margins for investors, in an obvious attempt to quell any concern that may be brewing after its spin -off.
More exciting, Sandisk also took the opportunity to reveal details of a new great capacity SSD that arrives later in 2025.
1PB SSD incoming
The UltraqlC DC SN670 is a SSD NVME PCIE GEN 5 QLC Data Center that promises faster reading speeds and 55% faster writing speeds “compared to competition.” This will be Sandisk’s first 128TB SSD (with a usable capacity of 122.88TB), following similar units of Soldigm, Samsung and Phison. This, together with a 64TB model (61.44TB usable), is expected to debut in the third quarter of 2025.
Blocks and files Notes: “The ultraqlc angle refers to the controller that has hardware accelerators, which is scalable for the level of died/channel 64, capable of climbing the feed according to the demand for the workload and including a ‘bus control of Integrated Advanced Lever Bus. The NAND alternative mode uses a double data speed interface for faster data transfers and a multiplexor (MUX) manages the data lanes. The Sandisk version of this technology will administer the data flow of the NAND-SSD controller more efficiently. “
Although he did not provide an exact timeline, Sandisk also mocked that he is working towards a 1PB data center unit, possibly in the next four years. However, he confirmed a 256TB goal in 2026 and 512TB in 2027.
While Sandisk usually uses TLC Nand for SSDS performance, and QLC NAND for capacity units, the company will change towards QLC for most of the purposes by 2028 (Sandisk made fun of BICS9 with more than 300 layers that will be used to make me make a 1TB tlc dies)).
At the end of this year, the arrival of a PCIE Gen 4 QLC NAND value in 512 GB, 1 TB and 2TB capacities, and also a PCIE Gen 5 TLC unit in 512GB, 1TB, 2TB and 4TB capacities.
