Samsung announced its recent entry into the commercial market of new 2.5-inch SSD drives with capacities of 1TB, 2TB and 4TB. These are devices based on “four-bit-per-cell” technology, better known as QLC (quad-level cell), and are the first in the commercial SSD market.
Otherwise, the name itself suggests that QLC technology allows one cell to keep four data bits, and so far it was only available on Toshiba’s disk drives for the business sector. But only a shorter time. That’s why this is especially what Samsung does at a commercial level, but at the same time from the South Korean company warns of the drawbacks that come with those disks.
“Performance and speed may be weaker because of this increased density,” he notes from Samsung, which is not a common occurrence as the company or users only talk about the benefits of what they offer.
Anyway, QLC has its place in the market because it is primarily smartphones, which will have increased capacity and not only it’s internal but also the SD cards that support exceeding these few terabytes of capacity. It’s important to jump and move to the mobile world so this reduced performance and speed will not be such a problem. After all, Samsung also points out that speeds are at the level of those offered by SSDs with cells that store up to three bits.
And when it comes to speeds, receiving data will take up to 540Mbps, and the data rate will be up to 520Mbps. So something will satisfy even the more demanding users. Additionally, each SSD disc of this type comes with a three-year warranty, which gives users the freedom to handle the data that matters to them.
As for the price and exact date of entry to the market, Samsung has not yet announced it but is expected to be present at the IFA fair in Berlin next month
