Why are SSDs with larger capacities faster?

If you’ve ever purchased an SSD, you know that larger capacities come at a more fantastic price, which, depending on your budget, may lead you to choose smaller capacity and lower pricing. But did you realize that larger solid-state drives offer more significant benefits?

Traditional hard disks, or HDDs, include a physical reading and writing mechanism and a reading head that searches the cylinder for the sector we want to read or write in the matching block.

Solid-state drives (SSDs) use a high-speed controller to access the device’s NAND modules in parallel, storing data in NAND flash memory. So, in an SSD, we discover that adding more NAND modules allows the controller to access more memory modules at once, allowing for faster read speeds.

We can’t add more modules to a low-capacity SSD

Because it costs almost the same to generate 64GB memory as 128GB memory, companies that develop NAND memory chips would make less money by creating smaller memory modules. However, to reach the 250GB SSD, they would have to build a more significant 64GB module, implying higher production costs.

For this reason, we discovered disparities in reading speeds between lower and greater capacity SSDs. At the same time, it may appear reasonable; producing them with lesser capacities and smaller modules would result in a financial loss for corporations.

We found improved read and write performance in smaller solid-state devices thanks to controller and NAND manufacturing techniques, such as 2D or 3D, making the difference less noticeable.

SSDs with larger capacities provide us with greater advantages.

The fact that an SSD contains more memory modules implies that the workload of the sectors is lessened, which increases its durability because it will take longer to reach the SSD’s sector’s limit of usage – unless you use the SSD to its capacity limit. As a result, a more significant capacity SSD provides us with superior performance, capacity, and longevity.
