When it comes to storage products, Chinese consumers are no strangers to SanDisk. As the world's largest memory card supplier, SanDisk is recognized as a leading brand in the storage industry. In 2016, SanDisk was acquired by Western Digital and operated independently as its subsidiary.
 
As the core component of the USB flash drive, the manufacturing of flash memory particles requires strong capital strength and technology accumulation. SanDisk and Toshiba have joined forces to build a joint venture to produce flash memory chips. SanDisk has the world's second-largest market share of flash memory chips, second only to Samsung. SanDisk USB flash drives are made with self-produced granules, and the quality of the products is guaranteed.
 
SanDisk's USB flash drive products are excellent, and the previous generation flagship CZ80 has received unanimous praise from the industry, and has been named the "Best Choice Award" by The Wirecutter. SanDisk also has a proven track record of product innovation. In 2014, SanDisk released the first mobile phone flash drive for iPhone, leading the trend of mobile phone USB flash drives.
 
SanDisk USB flash drive products are very complete, according to the performance from high to low, divided into three series: Extreme Speed, Extreme Speed, and Extreme Speed, plus the Apple mobile phone USB flash drive "Enjoy" series. The warranty period of the Xinxiang series is two years, the extreme high-speed series provides a five-year warranty, and the superior ultra-high speed and extreme speed series products with better performance provide a lifetime warranty, so users can use it with confidence. All SanDisk USB flash drives come with data encryption software, which allows users to easily encrypt data. The Extreme and Extreme series also come with data recovery software, which is convenient for consumers to retrieve the lost data deleted by mistake.
 
The SanDisk Extreme PRO CZ880 delivers superior performance and uses an SSD-level controller for significantly faster read and write speeds. The actual sequential read speed exceeds 300MB/s and the write speed exceeds 250MB/s, which is more than twice the performance of the entry-level Extreme high-speed series. It is worth noting that although CZ880 uses a solid-state drive control chip, and the official advertises it as a "solid-state flash drive", there is still a certain gap in the performance of CZ880 compared with portable solid-state drives. CZ880 has superior performance and is also more expensive, with the 128G version priced at 569 yuan.
 
SanDisk Extreme Series CZ800 is positioned in the high-end, compared with Kingston DTEG2 of the same level, CZ800 has a faster write speed, and provides a lifetime warranty, 128G version is priced at 399 yuan, which is extremely cost-effective. The CZ73 Extreme high-speed series has an actual read speed of more than 120MB/s, but as an entry-level product, its write speed is relatively average. The CZ73 has a metal casing with a business-like feel, and there are a wide range of capacities to choose from, ranging from 16G to 256G. The 32G version is 66.9 yuan, which is cost-effective.
 
The need for mobile phone expansion has led to the creation of USB flash drives that support mobile phone interfaces, and the SanDisk Joy USB flash drive has dual USB and lightning interfaces to manage USB flash drive files on the iPhone through a dedicated app. The SanDisk Ultra CZ450 has a Type-C port, which can be connected to most Android phones and new computers, making it easier to expand the phone.
