Samsung Announces 4TB QLC SSDs For Consumers

Samsung claims its drive will be the "industry's first 4-bit consumer SSD", but we'll have to see about that.

You can look forward to the initial 4TB QLC SSDs arriving later this year.

The 4TB drive will use just 32 of its fourth-generation, 64-layer 1-terabit V-NAND chips, Samsung said. If so, here's some good news from Samsung. HotHardware said the 1TB model "performed well" at low queue depths and "actually finished near the top of the pack in 4K QD1 transfers", while PCWorld praised the drive as the "best of the bargain NVMe SSDs", save for a concerning drop in write speeds in situations most users are not likely to encounter.

As Samsung notes, this is a massive step up from the 32GB one-bit SSD it launched in 2006, followed by its two-bit 512GB SSDs in 2010, and three-bit or triple-level cell SSD in 2012.

Typically, as data stored within a memory cell increases from three bits to four, the chip capacity per unit area would rise and the electrical charge (used to determine information from a sensor) would decrease by as much as 50%, making it considerably more hard to maintain a device's desired performance and speed.

The drives will come with three-year warranties. And although Samsung didn't share any pricing information for the new SSDs, the language in the press release makes it clear that these are aimed at consumers (and thus will be more affordable). The 2 and 4 TB drives will still be a bit spendy, but the 1TB tier should offer a solid price advantage over current 1TB solid-state drives.

In addition to high-capacity SSDs, Samsung also revealed that with its new chip, it will be able to "efficiently produce a 128GB memory card for smartphones that will lead the charge toward higher capacities for high-performance memory storage".
