Compared to flash drives in same form factor, maximum rotating disk drive capacity is much smaller, [citation needed] with 100 TB available in 2018, [1] and 32 TB for 2.5-inch. [ 2 ] The disk drive size, such as 3.5-inch, is usually refers to the diameter of the disk platters .
On September 8, 2008, Intel began shipping its first mainstream solid-state drives (SSDs), the X18-M and X25-M with 80 GB and 160 GB storage capacities. [1] Reviews measured high performance with these MLC -based drives.
$0.019/GB 2023 8 TB $175 $0.022/GB Solid-state storage has seen a similar drop in cost per bit. In this case the cost is determined by the yield, the number of viable ...
HDDs, as of early 2018, were priced around $0.02 to $0.03 per gigabyte for 1 TB models. [23] Storage capacity By 2018, SSDs were available in sizes up to 100 TB, [24] though lower-cost models typically ranged from 120 GB to 512 GB. HDDs of up to 30 TB were available by 2023. [25] Reliability – data retention
As of 2018, HDDs were forecast to reach 100 TB capacities around 2025, [39] but as of 2019, the expected pace of improvement was pared back to 50 TB by 2026. [40] Smaller form factors, 1.8-inches and below, were discontinued around 2010. The cost of solid-state storage (NAND), represented by Moore's law, is improving faster than HDDs.

114 minutes of uncompressed CD-quality audio at 1.4 Mbit/s is approximately 1 GB. A single-layer DVD+R disc can hold about 4.7 GB. A dual-layered DVD+R disc can hold about 8.5 GB. A single-layer Blu-ray can hold about 25 GB. The largest Nintendo Switch cartridge available on the market holds about 32 GB. A dual-layered Blu-ray can hold about 50 GB.
While storage devices usually have their size expressed in powers of 10 (for instance a 1 TB Solid State Drive will contain at least 1,000,000,000,000 (10 12, 1000 4) bytes), filesystem limits are invariably powers of 2, so usually expressed with IEC prefixes.
