SATA, IDE PATA, SCSI/SAS Hard Disk (HDDs) & Solid State Drives (SSDs)
Visit Page 3 – Useful information on hard disk and SSD drives
This section of this website provides detailed information on the various types of hard disk drives (HDDs) and SSD drives – internal, external and portable drives – IDE PATA (old technology), SATA (current technology for both HDDs and SSDs), SCSI/SAS drives (old and new technology, respectively) and the latest-technology solid state drives (SSDs). The categories of these drives are internal – installed inside the computer – external and portable. The Contents menu below gives a good idea about the information provided on each page.

PCI Express (PCIe) backwards compatibility
PCIe 4.0: What’s New and Why It Matters –
“PCIe is also backward compatible. If you have a PCIe 4.0 graphics card [or a PCIe NVMe SSD] you can use it with a motherboard designed for PCIe 3.0; however, the card’s available bandwidth would be limited to the capabilities of PCIe 3.0. Conversely, a PCIe 3.0 card can fit in a PCIe 4.0 slot, but again it would be limited by PCIe 3.0.”
In other words, a PCIe 3.0 card can only have the capabilities of a PCIe 3. 0 device in a PCIe 4.0 slot on the motherboard.
eMMC storage is not an SSD
If you come across a cheap laptop or tablet that uses eMMC storage that holds the operating system (Windows 10, Linux, Android), it is not a type of SSD drive, it is an eMMC chip soldered into the device’s motherboard. That chip does not have a controller and does not use firmware that hard disk drives and SSDs use.
Wikipedia: “Almost all mobile phones and tablets used this form of flash for main storage up to 2016, in 2016 UFS started to take control of the market. The latest version of the eMMC standard (JESD84-B51) by JEDEC is version 5.1 released February 2015, with speeds rivaling discrete SATA-based SSDs (400 MB/s).”
Laptops that use eMMC storage can run Windows 10 and Microsoft Office very well. A good example is the

External hard disk drives and USB flash drives
External hard disk drives and USB flash drives have their own pages in the Hardware menu – Hard Disk and SSD Drives => External Hard Disk Drives => USB Flash Drives. Network Attached Storage (NAS) devices are dealt with in the the Wired and Wireless Networking pages, also in the Hardware menu.
How to find out which hardware and software is installed on a Windows computer
If you need information on what is installed on a computer, the Belarc Advisor from belarc.com is a free tool (look under Free Download on its website) that identifies a Windows computer’s hardware (motherboard, graphics card, hard disk drive(s), DVD drive, etc.) and software (version of Windows, applications, etc.) and even software licences, including the Windows Product Key, which is always required when reinstalling Windows. Look on the left hand side of the Belarc Advisor screen for “Software Licenses”.
