![]() When buying an internal SSD to upgrade or augment a system you own, you need to start by figuring out what your system can actually accept: a 2.5-inch SATA drive only? Does it have an M.2 slot? What length of M.2 drive can it take, and using which bus type? If you're upgrading a laptop, in most cases you'll have the option only to swap out the internal drive, not to add another. (If you'd like a deep overview of all the SSD terms shoppers should know, check out our SSD dejargonizer for a full breakdown.) M.2 drives and AIB SSDs transfer data between the drive and computer via one of two bus types: the same Serial ATA bus used by 2.5-inch drives, or the PCI Express bus, the lanes and pathways of which can also be used by other hardware, such as graphics cards. Within those three physical forms are some crucial variations, though. You'll see them in three main physical forms: (1) 2.5-inch drives, (2) M.2 drives, and (3) add-in-board (AIB) SSDs. On average (because of the limitations of current bus technology), the higher end of the sequential speed spectrum you should expect to see over the fastest current interfaces (Thunderbolt 3 or USB 3.2 Gen 2x2) is in the range of 2,500 megabytes per second (MBps) for reads and 2,000MBps for writes. ![]() Most are built for portability, with some small enough to fit on a keychain. But it's good to know some nuances regarding how fast each kind can be.Įxternal SSDs are drives with their own standalone enclosures, which plug into your laptop or desktop via a USB cable or (less commonly) a Thunderbolt 3 cable. "Internal" means the drive goes inside a desktop PC's or laptop's chassis, while "external" means it connects to a computer via a cable. Most of what you need to know is obvious from the name. Are You Upgrading a Laptop or a Desktop?įirst, some context on the difference between internal and external SSDs. This guide will help you sort through the different (and often confusing) terminologies associated with SSDs, as well as learn what you need to know when it comes to pricing, speeds, durability, warranty durations, and more. SSD interfaces have evolved greatly over the last few years, and SSDs themselves are taking on different shapes and core technologies. That said, while almost any SSD is much faster than any hard drive, not all SSDs are created equal-not by a long shot.

I have to manually update (the cumulative update 2017 - 10) because the windows update is stuck at 22%. After about two weeks not using Windows 10, now the 100% disk usage happens again.
