When the new drive has been installed, the system image can be Category j Game Center restored to it. A system image is technology neutral, so an Topic 8C: Install and Configure image of an HDD can be applied to an SSD. However, the new Laptop Hardware " Resources drive must have storage space greater than or equal to the old one, unless using a cloning tool that can shrink the source image. As an alternative to using a third USB drive to store the image, a disk enclosure allows you to connect an internal drive temporarily as an external drive. You can then migrate the image directly to the SSD before removing the old drive and installing the new one. Replacement means that only data is backed up from the old drive. The new drive is then fitted to the laptop and an OS plus apps installed. User data can then be restored from backup. The fixed disk can usually be accessed via a panel, but you may have to open the chassis on some models. Laptop HDDs are usually 2.5" form factor, though sometimes the 1.8" form factor is used. Compared to 3.5" desktop versions, magnetic 2.5" HDDs tend to be slower (usually 5400 rpm models) and lower capacity. Within the 2.5" form factor, there are also reduced height units designed for ultraportable laptops. A standard 2.5" drive has a z-height of 9.5 mm; an ultraportable laptop might require a 7 mm (thin) or 5 mm (ultrathin) drive.  *    u Learning Plan C Strengths & Weaknesses k Lessons X PBQs , Labs r Practice A laptop HDD with SATA interface.

Drive bays measuring 1.8" j Game Center might require the use of the micro SATA (μSATA or uSATA) connector. " Resources An SSD flash storage device can also use the SATA interface and connector form factors but is more likely to use an adapter card interface: mSATA—An SSD might be housed on a card with a Mini-SATA (mSATA) interface. These cards resemble Mini PCIe cards but are not physically compatible with Mini PCIe slots. mSATA uses the SATA bus, so the maximum transfer speed is 6 Gb/s. M.2—An M.2 SSD usually interfaces with the PCI Express bus, allowing much higher bus speeds than SATA. M.2 adapters can be different lengths (42 mm, 60 mm, 80 mm, or 110 mm), so you should check that any given adapter will fit within the laptop chassis. The most popular length for laptop SSDs is 80 mm (M.2 2280). The specific M.2 form factor is written as xxyy, where xx is the card width and yy is the length. For example, 2280 means a card width of 22 mm and a length of 80 mm.  Report Content Errors Copyright © CompTIA, Inc. All Rights Reserved Terms of use Privacy Statement Trademarks
