This question definitely comes in your mind when it comes to storage. Well, you are in the right place! Here you will find everything to choose from- SSHD vs HDD and SSD vs SSHD.
At first, let's take a look about these storage devices - HDDs, SDDs and SSHDs and how it works after that we will go to our main topic of discussion i.e. SSHD vs HDD and SSD vs SSHD
HDD(Hard Disk Drive)
Hard Disk Drive (sometimes abbreviated as a Hard Drive or HD or HDD ) is the component of a computer connected to a power supply that can store data while the machine is shut down.
It is a non-volatile storage device installed internally in a computer that uses mechanical platters and moving read/write heads to access data.
Mostly the major storage hardware in any type of computer is HDD. HDD stores the OS, data files, and all programs. It can be found in mobile devices, desktop computers, consumer electronics, and enterprise storage arrays in data centers.
How HDD works?
The numbers of disk platters consist of the most basic hard drives which are positioned around a spindle inside a sealed chamber which also includes read and write heads & motors.
The Platters which hold the data are spun by the motor up to 15,000 rotations per minute. While the platters spin, a second motor controls the position of the read-and-write head. Read-write heads record information magnetically and read information from the tracks on each platter.
SSD (Solid-State Drive)
The solid-state drive is a new generation of storage devices used in computers. The solid-State drive uses significantly faster flash-based memory which replaces traditional mechanical hard disk.
As we know that older hard disk storage technologies run slower and today's generation doesn't want to wait so our SSDs technology has reduced accessed time as compares to HDDs.
As HDDs, SSDs serve the same purpose, they store files and data for long-term use. The only difference is the "flash memory". SSDs use the type of memory which is like RAM but whenever the computer shuts down, RAM clears its data but data remains on SSD even when its power runs out.
However, Solid-state drives come with a higher price tag than consumer-grade Hard disk drives.
How SSDs work?
The Solid-State Drives uses a simple memory chip called NAND flash memory which has no moving parts. Files are saved on a grid of NAND flash cells instead of a magnetic platter.
The Solid-State Drive uses a grid of electrical cells that quickly receive and send the data. These grids are separated into sections which are called "pages" where data is stored. Pages are then interlinked to form "blocks".
SSDs have no moving parts so they are called "Solid-State".
SSHD (Solid-State Hybrid Drive)
Solid State Hybrid Drive is a combination of Solid-State Drive and Hard Disk Drive. It is the same as a Hard disk which has a very small amount of solid-state storage, approximately around 8 GB.
It provides an absolute solution for performance and storage within a budget. By combining both technologies, the benefits of the technologies provide you storage capacities like Hard Disk Drive and working performance like Solid-State Drive
On the Solid-State Drive portion of the drive, commonly used and fast access data is stored and on the Hard Disk Drive portion larger and less used bulk of data is stored.
How SSHD Works?
The technology of SSHD works by using a small amount of memory of NAND flash solid-state to store the most often used data. The portion of using Solid-State Drive for accessing files far quicker than Hard disk drive. The rest of the SSHD is made up of HDD storage.
Displayed as a single device for most Operating systems, SSHD has a controller chip which helps to decide which data is to be stored on SSD and which on HDD.
By now, you have a little idea about SSDs, HDDs, and SSHD. Now you may think which storage will best suit your needs.
Let's compare - SSHD vs HDD and SSD vs SSHD to help you to choose the right one. There are some parameters that will help you to find: Among SSHD vs HDD and SSD vs SSHD which one is the best?
SSHD vs HDD vs SSHD
|Solid-State Hybrid Drive consists of both mechanical platters and flash memory cells. So these drives can provide best for the both worlds.
||Hard disk drive use mechanical arms to access data on platters, the process is slow and hard drives can be fragile.
||Solid-State Drive uses flash memory, just like a USB and due to this it has a high read-and-write speed. SSD consists of multiple cells used to store data electronically using transistors whereas,
|Solid-State Hybrid Drives are available in 500GB , 1TB and 2TB options in the market. The SSHD comes with an 8 GB flash memory cell. These all are relatively starting at low price of $50 in the market.
||Hard disk drives offer storage up to 15 terabytes. As compared to SSD, HDD provide storage for low price. A 5TB Hard Drive is available for around $49 in the market.
||Solid-State Drive can stores up to 8 TB but as compared to HDD , these are much more costly. A 5TB Solid-State Drive will cost around $125 in the market whereas,
|Solid-State Hybrid Drive lies in between both, which means that SSHD are faster than HDD but slower than SSD. They provide read/write speed of approx of 150MB per second.
||Hard disk Drives reads data at slower rates of 125MB per second. With HDD memory laptop take many more minutes to boot up as compared to SSD.
||Solid-state drive has read/write speed of 500MB per second . It takes only a few seconds to boot up a laptop. There are different types of SSD available in the market whereas,
|The life span of Solid-State Hybrid Drive last much longer.
||The life span of Hard Disk Drive is longer in terms of read and write cycle.
||The life span of Solid-State Drive is shorter because its flash memory can only be used for a limited number of writes whereas,
|Solid-State Hybrid Drive uses genuine amount of power.
||Hard Disk Drive uses large amount of power.
||Solid-State Drive uses less power.|
I hope you have now a clear idea about which one among SSHD vs HDD vs SSD to choose from. If you are concerned about storage you can choose HDD, and if you are concerned about speed then choose SSD, whereas SSHD lies between the two. If you want to explore new things then go with SSHD.
