Intel has released the budget 330 series solid state drive in 60, 120, and 180 GB capacities using 25 nm flash memory and a SandForce controller that have replaced the 320 series. [20] [21] In late 2015, Intel announced that they were producing their first consumer PCIe-based solid state drive, to be named the 750 series.
As of early 2018, SSD prices were around $0.30 per gigabyte for 4 TB models. [23] 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.
Mark Kryder, who projected in 2009 that if hard drives were to continue to progress at their then-current pace of about 40% per year, then in 2020 a two-platter, 2.5-inch disk drive would store approximately 40 terabytes (TB) and cost about $40.
2011 - Samsung announces 1 TB of capacity per 3.5 inch hard drive platter. [60] 2012 – TDK demonstrates 2 TB on a single 3.5-inch platter [61] 2012 – WDC acquires HGST operating it as a wholly owned subsidiary. WDC then provides rights to Toshiba, [62] allowing it to re-enter the 3.5-inch desktop hard disk drive market. [63]
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.
Flash gross margin was 38.9%, up 240 basis points sequentially, driven by a higher mix of enterprise SSD bits improvement in like-for-like pricing and continued cost reduction.
A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts. [4]
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.
