When buying or customising a laptop, get the best storage. SSDs are faster than hard drives, but can you afford one? Do all your files fit? not all SSDs are fast
SSD vs. HDD
Even a sluggish SSD is three to four times faster than the fastest mechanical hard drive.
your hard drive spins at 5,400 rotations per minute (rpm) or 7,200 rpm, it's inherently limited in comparison with an SSD, which is a series of Flash memory chips that move data around inside the silicon.
SSDs improve programme launches, file opens, task switching, and booting. Microsoft Word opened 31.9 seconds faster on an SSD than a hard disc in a Dell Inspiron 15 5000.
The smallest common SSD size is just 128GB, which is about 25 percent of the capacity of the 500GB hard drives you find on many budget laptops.
Typical conventional hard drives use the same SATA (or SATA 3) interface as mechanical hard drives, however that connection is restricted to roughly 550 megabytes per second.
Some of the cheapest laptops (around $300) use eMMC (Embedded MultiMedia Card) memory, usually 32 or 64GB.
Manufacturers sometimes identify SSDs as M.2 or 2.5-inch. These classifications pertain to size, shape, and connector, not performance. You shouldn't bother about the SSD's design unless you plan to upgrade your laptop.
