Sony's imaging products have excellent performance, and memory cards are also an important part of ensuring the performance of imaging products as an imaging accessory. Most of Sony's own memory card products are positioned for professional image shooting, and they have outstanding performance in terms of write speed.
 
Sony developed memory cards very early, in 1998 to develop its own storage products, in 2005 with SanDisk also developed the M2 memory card, but with the entire memory card market to SD unification, Sony's current main memory card products have also been transformed into SD cards.
 
Sony's SD card model number starts with SF, and Micro SD card products start with SR. However, there are not many Micro SD cards under Sony, and the cost performance is not high, so it is not recommended to buy. In contrast, Sony's standard SD card products have superior performance, and all Sony SD cards come with data recovery software, and the products are easy to use.
 
As the storage hardware used in imaging products, the write speed of the SD card is more important than the read speed. Sony's SF-G series is the highest-performing SD card on the market, with a maximum read speed of 300MB/s and a write speed of 299MB/s. For the SF-G series, Sony has also launched memory card life detection software, which can detect the status of memory cards at any time. Under the powerful performance of the SF-G series, the price is naturally not cheap, 64GB version 1099 yuan.
 
The SF-M series is also a professional-grade SD card, with a maximum read speed of 260MB/s and a write speed of 100MB/s, which is also capable of 4K video shooting. The 64GB version is 649 yuan, which is less cost-effective than the more powerful Toshiba N502.
 
Sony's professional-grade memory cards also include CFast cards and XQD cards, CFast cards CAT-G have a maximum write speed of 510MB/s, XQD cards have a maximum write speed of 400MB/s, CFast cards and XQD cards have excellent performance, in addition to the high price, the two are not suitable for many devices, most of them are Canon EOS-1D X Mark II or Nikon D5 professional imaging equipment, which are recommended for users with corresponding needs.
 
Sony's memory cards for the general public are slightly less cost-effective than professional-grade products. The SF-UZ series, for example, has a maximum read speed of 95MB/s and a write speed of 90MB/s, which is similar to the performance of the SanDisk Extreme Pro UHS-I memory card, but the SF-UZ is twice as expensive as the SanDisk Extreme Pro. Users who need consumer-grade memory cards are recommended to buy products from brands such as SanDisk and Lexar.
