A Mushkin 1TB 2280 NVMe SSD. 2280 is the most common size for NVMe SSDs. However, 2230 NVMe SSDs are becoming more common to save space in the system board. A SSSTC 256GB 2230 NVMe SSD. Since 2020, Dell (and others) started to use 2230 SSDs in their laptops instead of the more common 2280 size to save space.
For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs), and 2048 bytes for CD-ROMs, DVD-ROMs and BD-ROMs. [1] Newer HDDs and SSDs use 4096 byte (4 KiB) sectors, which are known as the Advanced Format (AF). The sector is the minimum storage unit of a hard drive. [2]
However, because file systems write pages of data that are smaller (2K, 4K, 8K, or 16K) than the blocks of data managed by the SSD (from 256 KB to 4 MB, hence 128 to 256 pages per block), [50] over time, an SSD's write performance can degrade as the drive becomes full of pages which are partial or no longer needed by the file system.
Density is a measure of the quantity of information bits that can be stored on a given physical space of a computer storage medium.There are three types of density: length (linear density) of track, area of the surface (areal density), or in a given volume (volumetric density).

In North America the laptop comes in two configurations with the base model using an 8th-generation Intel Core i5-8250U processor with 8 GB of RAM, 256 GB of SSD storage and Intel UHD Graphics 620 while the higher-end model packs an 8th-generation Intel Core i7-8550U processor with 16 GB of RAM, 512 GB of SSD storage and a dedicated NVIDIA ...
On 7 July 2016, Samsung announced its first UFS cards, in 32, 64, 128, and 256 GB storage capacities. [22] The cards were based on the UFS 1.0 Card Extension Standard. The 256 GB version was reported to offer sequential read performance up to 530 MB/s and sequential write performance up to 170 MB/s and random performance of 40,000 read IOPS and ...
