You can find SSHDs with a capacity up to 14 TB and an 8GB SSD cache, whereas SSDs are usually capped at 4 TB. Unlike an HDD, both the SSD and HDD components of SSHD are wielded into a single piece of hardware.īoth disk drives are available in 2.5- and 3.5-inch size variations, though SSD also comes within the M2 form factor which is much smaller in size. On the other hand, SSHD contains both a regular hard disk and NAND memory which serves as a big cache buffer (generally 8 GB).
SSD is flash storage similar to a USB drive but is much faster, as it uses NAND memory. The drive appears as a single device to Windows (or any other operating system), and the SSD part is just used for temporary storage to speed things up: your data is stored long-term on the mechanical disks. So an SSHD is basically a hard drive and SSD in one, which is why it’s called hybrid. It’s a bit like the storage in a USB thumb drive, but much faster. A solid-state drive – or SSD – is a storage drive made entirely of memory chips instead of the spinning magnetic platters you’d find inside a traditional hard disk. It’s a traditional spinning hard disk with a small amount of fast solid-state storage built in.
