In 2022, Hikvision was awarded a Chinese government contract to develop software to track "key people" in order to prevent them from entering Beijing. [16] [17] The same year, IPVM also reported that Hikvision has specific alarms in its software to alert Chinese police to "religion, Falun Gong, and various protest activities. [18]
Historically, most SSDs used buses such as SATA, SAS, or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and it became increasingly inadequate for SSDs, which ...
When a flash controller is expected to operate with various NAND flash chips, it must store a table of them in its firmware so that it knows how to deal with differences in their interfaces. [ 4 ] [ 5 ] This increases the complexity and time-to-market of flash-based devices, and means they are likely to be incompatible with future models of ...
This Intel 120GB SSD also appears to be in perfect condition. [ 2 ] Self-Monitoring, Analysis, and Reporting Technology ( S.M.A.R.T. or SMART ) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [ 3 ]

Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. Some, however, must resort to exploits to run, because the manufacturer has attempted to lock the hardware to stop it from running unlicensed code. Most firmware hacks are free software.
Dahua issued a firmware update to fix the vulnerability in 11 of its products. [76] Security researchers discovered that the updated firmware contained the same vulnerability but that the vulnerability had been relocated to a different part of the code. This was characterized by the security researchers as deliberate deception. [72]
Defragmentation should be disabled on solid-state drives because the location of the file components on an SSD does not significantly impact its performance, but moving the files to make them contiguous using the Windows Defrag routine will cause unnecessary write wear on the limited number of write cycles on the SSD.
