If PCIe SSDs are faster than SATA drives, why wouldn’t you simply make the PCIe standard for all? There are some distinct use cases for SATA. This communication protocol was created to work with flash memory via the PCIe interface at speeds that are more than four times faster than a SATA interface. In 2008 PCIe SSDs were given a big upgrade with the introduction of NVMe (NVM Express, or Non-Volatile Memory Express). PCIe SSDs, on the other hand, connect directly to the PCIe slot and are smaller in size, enhancing speed and performance. However, the additional distance for data to travel caused by the cable can increase latency. This allows the SSD to read data at speeds of up to 550 MB/s and write at around 500 MB/s. SATA was built with HDDs in mind and uses a special cable to connect a drive to the motherboard. There are actually four types of SSD form factors: serial advanced technology attachment (SATA), small computer system interface, Fibre Channel and the most recent option available - PCIe. What’s the difference between a SATA-based SSD and a PCIe-based SSD - and what’s NVMe? While every PCIe card is backward compatible, if you put a PCIe 4.0 SSD card into a 2.0 slot, the performance can only achieve 2.0 rates. That said, capabilities depend on the slots they go into. PCIe SSDs are distinct from SSDs without PCIe in that they access the computer’s PCIe slot, which is also used for high-speed video cards, memory and chips. Flash memory cells retain data regardless of whether the system is turned on or not, and software is used to retrieve that data when it’s needed. PCIe SSDs are like other SSDs in that they use flash memory to store files and applications. So what is PCIe SSD used for, exactly? And why should you care? Below, we address four top questions about this technology and why it’s something consumers and businesses need. A PCIe ® allows for high data transfer rates, and with little to no slow down. The implementation of SSDs became even more pronounced in 2003 with the development of a low-latency computer expansion bus known as a peripheral component interconnect express (PCIe). In fact, in many cases, computing devices are only sold with SSDs, especially in the midrange and above. ![]() ![]() That’s why today, you’d be hard-pressed to find any computing device sold without an SSD or SSD compatibility. From the start, SSDs were faster and more reliable than traditional hard disk drives (HDDs), and as the technology evolved, that difference increased. When solid state drives (SSDs) first launched, there was great anticipation, and for good reason.
