Speed: SSD vs HDD

A solid state drive reads up to 10 times faster and writes up to 20 times faster than a hard disk drive. These are not outlying numbers, either, but the speeds of mid-range drives in each class. And the differences in speed are expected only to increase as computer motherboards progress from PCIe 3.0 to 4.0 connectors.

SSDs work so much faster than HDDs that a new interface — the connection between the drive and your computer’s motherboard — had to be invented to unleash their full power. They previously made use of the SATA interface, a holdover from the days when hard disk drives reigned supreme. This allowed people to easily replace their HDDs with SSDs, which was a necessary step in the transition to solid state drives.
These days, solid state drives can work as they were always meant to, thanks to NVMe — a new type of SSD interface collectively developed by Intel, Sandisk, and other leading manufacturers. Whereas older SATA drives allow the transfer of information only along one channel, NVMe makes use of multiple channels that can read and write at the same time.
That allows NVMe drives to read and write data way faster than their SATA counterparts.
•    On a typical HDD, copying a large file, such as a movie or graphic design project, happens at a relatively pedestrian rate of 15 to 30 MB/s. A SATA SSD can copy the same file at 500 MB/s, while a newer NVMe SSD will reach speeds of 3,500 MB/s — that’s 3.5 GB per second. If you’re backing up your data from one drive to another, it’ll go way faster with an SSD.
•    SSD drives also perform smaller read/write operations at far faster speeds, which makes your computer feel much more responsive. Most normal computer tasks, such as opening a program or browsing the web, require your operating system to access smaller bunches of data in groups of 4 KB. HDDs can access this data at speeds of 0.1 to 1.7 MB/s, while an SSD can offer speeds of 50 to 250 MB/s for these “4K read/write” operations.
Put simply, SSDs — which were already much faster than HDDs even when using an obsolete transfer protocol — blow HDD speeds out of the water.
But regardless of Whether you have an HDD or SSD, you’ll continue to get peak performance from your storage device with ANKMAX H2U30C. No need to connect to a computer, the cloning function of ANKMAX H2U30C can realize offline high-speed cloning from HDD to HDD, SSD to SSD, HDD to SSD, SDD to HDD. The cloning speed of SSD can be as high as 485MB/sec.It only takes 30 minutes to complete the cloning of a 1TB SSD. The capacity of a single supported hard drive can be as high as 18TB.
