What is an SSH Hybrid HDD? What are the advantages of SSHD hybrid hard drives

SSH Hybrid HDD: A new product that combines the stability, low power consumption, and speed of flash media with the ultra-high storage density and low cost of magnetic drives.

As the name suggests, a hybrid hard drive is a combination of a mechanical hard drive and an SSD, and the hybrid hard drive uses smaller flash memory particles to store commonly used files, usually between 8 and 16GB of capacity. That is, HDD hard disk (SSD) with built-in flash memory cache. SSHDs add a fraction of fast, affordable NAND flash memory to traditional hard drives.

Disk is the most important storage medium, and flash memory only plays a buffering role, saving more frequently used files to flash memory, reducing seek time and improving efficiency. Combining the best of both traditional and solid state drives: fast, high-capacity, and affordable.

The advent of solid-state hybrid drive (SSHD) technology provides a way for users to achieve higher device performance, richer applications, and greater contributions – and in a justified way'Make it happen.

As we all know, SSDs are fast enough, but they have small capacity and are expensive; Although the speed of HDD is average, it has a large capacity and is cheap enough. SSHD is designed to balance the sharp relationship between capacity, capacity and performance.

HDD: Large capacity.

SSD: High speed.

SSHD: Capacity, Performance, and Value.

SSHDs add a fraction of fast, affordable NAND flash memory to traditional hard drives. Combine the best of traditional hard drives and solid state drives to get the extraordinary speed of solid state drives, and combine the advantages of high capacity and high reliability of traditional hard drives.

Seagate's MomentusXT technology is currently the most popular, and Toshiba, Western Digital, and Samsung also have their own SSHD products.

It is a combination of traditional hard disk and solid state drive, its appearance is the same as that of traditional hard disk, but the advantages of hybrid solid state drive are mainly low power consumption, increased read and write speed, reduce the number of reads and writes of traditional hard disk, so as to extend the life of the hard disk, especially to improve the battery life of the laptop and the capacity is large and lower than the solid state drive.

There is a difference, the hybrid hard disk is mechanical + solid-state, and the solid state is the flash memory integrated into the hard disk.

SSH Mixing Disc. I haven't heard much of this, but I've heard of SSD hard disks, which are storage media made of solid-state electronic chips, and compared with conventional hard disks with built-in physical platters, SSD disks have the advantages of low noise, fast transmission, and light weight.

The concept of hybrid disk is a fusion of SSD and conventional disk, using SSD as a data buffer space, frequently read data will be recorded with this, which is equivalent to the role of memory in PC, so that the time of scanning the conventional disk can be reduced in ordinary times, thereby reducing the loss of the disk and the data reading time.

Since it is a hybrid, the concept of revs is only available in regular discs, so it still can't run the 5400rpm and 7200rpm that are now common in conventional discs.

The disadvantage is the same as the regular disk, but it is more complicated, there are more unknowns, and the failure will be higher than the conventional disk, and the more important point is that if you just hit the data in the buffer space more often, the speed will be very fast, but in practice, the chance of this continuous hit is relatively small, and most of them still need to read the data from the conventional disk. Because the regular disk starts to accelerate data reads and writes, it may now speed up in the middle of reads and writes. So it's not ideal in terms of speed.

SSDs are expensive, small in capacity, and fast.

Traditional HDDs** are low, large in capacity, and slow in speed.

Hybrid hard disk is an ordinary mechanical hard disk integrated with a small capacity solid state drive, which can put the data often read in a small capacity solid state drive, so as to achieve a low-cost method to improve the speed of the hard disk, so the solid state disk is fundamentally an ordinary mechanical hard disk, the speed is 7200 most, and compared with the traditional mechanical hard disk, the hybrid hard disk only has the advantage, no ***, in the most suitable case, it should be preferred.

Mechanical hard disk: It is assembled by a motor motor, a magnetic head, and a platter, and the mechanical arm is used to access data.

Features: large capacity, cheap, large voice, large power consumption, non-shock-resistant, large weight, slow speed.

Solid state drive: It is highly integrated by circuit board PCB, main control chip and flash chip, using flash memory technology to access data, characteristics: small capacity, high **, low voice, low power consumption, shock resistance, light weight and fast speed. It is the best alternative to mechanical hard disks and is the trend of the future.

Hybrid hard disk: It is a combination of the above two types of hard disks, generally using solid state drives to install the system, and using mechanical hard disks to store data. Hybrid hard drives can be used on desktops at home to greatly improve system performance.

You don't have to spend a lot of money to buy an SSD, it's acceptable.

Mechanical hard disk is a traditional ordinary hard disk, which is mainly composed of: platter, head, platter hinge and control motor, head controller, data converter, interface, cache and other parts.

Solid state drives, referred to as solid state drives, are hard disks made of solid-state electronic memory chip arrays, which are composed of control units and storage units (flash chips, DRAM chips). SSDs are identical to HDDs in terms of interface specifications and definitions, functions and usage methods, and are also completely consistent with HDDs in terms of product shape and size.

Hybrid hard disk is a new hard disk based on the traditional mechanical hard disk, in addition to the necessary disks, motors, heads, etc., but also built-in NAND flash memory particles, this particle will be frequently accessed by users to store data, can achieve such as SSD (that is, solid state drive) effect of reading performance.

Seeing you say this, it should feel the same, it's all a solid-state + mechanical hybrid disk.

SSHD SSHD is a hybrid hard drive, which is a combination of traditional hard disk and solid state drive, that is, SSD (flash memory) + traditional hard disk. Its main body is based on a mechanical hard disk, and the flash memory module is responsible for data computing and transmission, and the two are combined through advanced algorithms.

The advantages of hybrid SSDs mainly include low power consumption, increased read and write speeds, and reduced read/write times in the traditional hard disk part, so as to extend the life of the hard disk, especially to improve the battery life of the notebook computer and the capacity is large and lower than the SSD.

Strictly speaking, it can't be called a "hybrid SSD". Because it's more like a hard drive than an SSD.
