SSD Write For Us – Surely, a few years ago, you heard about SSDs for the first time. Do you know precisely what an SSD is and what its characteristics are? These storage units have significant advantages for our computers and other devices where they usually installed, but…
Throughout this article, I want to talk about this type of storage support, from how they work to their main advantages compared to traditional hard drives, without forgetting the different types or recommending some models you can currently buy.
However, do you want to discover everything about SSDs? Keep reading; here, you have all the information.
What is an SSD
An SSD (Solid State Drive) is a storage unit with non-volatile memory. These drives are based on flash memory chips, so they do not contain any moving or mechanical parts like traditional hard drives.
SSDs are the successors of the old EEPROM memories. One of their main advantages over them is that they can write and read in multiple positions simultaneously, something that the old memories could not do. Thanks to this, SSD-type memories are much faster, one of its advantages that attracts the most attention the first time you try it.
Its use is already widespread, and most computer manufacturers use this type of storage unit in their equipment. Thanks to technological advances, prices have been falling, and the advantages over hard drives outweigh their disadvantages; this has ensured that their popularity has not stopped growing since they arrived in stores.
We could say that a solid-state drive or SSD comprises different parts: the format, connector, and communication protocol. As far as the physical form is concerned, although initially, this type of storage unit arrived in a condition equal to that of hard drives, today we can find different forms, from 2.5 and 3.5-inch disks to M. 2 or SATA. The bus interface of an SSD determines the type of communication bus used at the physical level. Mainly, SATA3 and PCIe are used, although there are other types.
All SSDs also include a control or controller chip, which is in charge of the drive managing how to read and write information. On certain occasions, we can also find a DRAM chip operated by this controller, which acts as a cache of user data and internal metadata of the SSD.
How does it work
Current SSD technology is based on memory chips made of NAND logic gates. NAND gates are made from floating gate transistors, the element in which the bits are stored. The memories are organized in a matrix known as a block, and the different rows that make up the matrix are called pages. The number of pages within each block determines the total capacity of the SSD.
Regarding storing information, floating gate transistors have two possible states (binary system): charged or discharged. The loaded state represents 0, while the unloaded represents 1.
One of the most important appearances of the floating gate transistors used in SSDs is that they can store information even when not receiving power. Thanks to this, they can be used on computers commonly and can also be used as external drives to be used on various computers.
SSD vs HDD, differences, advantages and disadvantages
The differences between both technologies are apparent. Traditional hard drives (HDD) comprise a controller, platters, and a reader’s head. Much of the operation of this type of storage system is mechanical and needs to be in constant motion; some even call them mechanical disks.
These types of disks record data by magnetism and are usually made up of one or more hard disks joined by the same axis and rotating at high speed. We find a head to read or write data on the disk on each of its faces.
Therefore, the operation is purely mechanical; hence, the faster they rotate, the less time it will take to retrieve or record the information. Thus, The speeds in this type of disc are measured in revolutions per minute or rpm.
For their part, SSDs are entirely electronic. There are no moving parts, which makes them much faster in all reading and writing actions, silent, light, and resistant to shocks or sudden movements of the computer or device in which they are installed.
Main advantages SSD
- Faster read/write improves the performance of any computer installed where there was previously an HDD.
- It does not emit noise during operation.
- They do not vibrate with use because they do not have moving parts.
- They do not suffer from sudden movements.
- They are lighter.
- They can be smaller.
- They consume less energy.
- They are not affected by magnetism.
But, of course, not all are advantages of SSDs. One of the main drawbacks of SSDs is that their lifespan is usually more limited than that of hard drives. This type of memory has a finite number of possible delete/write operations, and beyond that number, its death is imminent; also, there are no symptoms of degradation; it can fail from one second to the next, and the data is irrecoverable. Backup copies are more critical than ever with this type of storage unit.
It is also important to note that its price per GB is higher than that of hard drives. Something that adjusts with the passage of time and the development of technology, but for the moment, the HDDs continue to win.
Main disadvantages
- Shorter useful life. Its cells can be rewritten a limited number of times, and their performance will decrease as these data write and delete cycles are carried out. In this sense, SSDs do not have a quantifiable helpful life in years, as is the case with HDDs, but rather, it is more related to the use we give it. Therefore, if they are discs that suffer/work a lot daily, their life will be substantially shortened. For everyday use, we will not have significant complications.
- Higher prices than HDDs, although with time, they are becoming more affordable for larger storage capacities.
- In the event of a failure, which is rare with current complex drive models, it will be much more difficult to recover data than if you had an HDD. The “problem” is that in the case of SSDs, the data’s position is stored differently than the HDD that transmits them magnetically, and they constantly change position to avoid data wear. So it is tough to recover them, and in some cases impossible.
- Less storage capacity. We are talking about both maximum total capacity, where they still do not reach HDDs, and in terms of the capacity/price ratio. In this sense, if you cannot afford a vast SSD disk, purchasing one large enough to install your operating system, necessary work applications, etc., and combining it with another HDD disk to store files is ideal. You will consult occasionally and do not affect the computer’s performance. For example, videos, photos, music, etc., usually occupy many GB.
Characteristics
In the following pieces, we review the main characteristics of SSDs from a technical point of view and the advantages they bring for day-to-day use.
Types of SSDs and their Memory
Meanwhile, floating gate transistor technology has evolved over the years. Thanks to this evolution, these units have increased their storage capacity.
These are the types of memories that manufacturers have used up to the time of writing these lines:
The construction of this type of chip is based on individual silicon wafers with which a thin chip can store one bit of data in each memory cell.
Its advantages include higher access speed, longer functional life, and lower energy consumption. All this is achieved thanks to the lower data density, although the downside is that the cost of its manufacture is much higher, and the storage capacity is lower.
These chips are less reliable and faster than the previous ones, but in return, they allow the creation of higher-capacity chips at a lower cost.
However, several silicon wafer molds are used for each chip to make them. This allows storing two bits for each memory cell (some manufacturers have managed to keep 3 bits). Due to this, the read/write rate is lower, although it is still much higher than that obtained in mechanical hard drives.
TLC chips allow up to 3 bits to be stored in each memory cell and are currently the most widely used commercially due to the low cost of producing them.
One of the most harmful points of this type of SSD is that it is limited to a useful life of about 1000 writes, although this figure expressed in time will always depend on the use you make of the computer or device where it is installed.
In this case, each cell can store up to 4 bits, making it possible to reduce the price of manufacturing this unit type. Specifically, QLC technology only allows a write/delete limit of about 100 times, which makes its useful life very short. It can be attractive as a storage unit for static files since there is no limit on reading access.
connections
Different types of SSD connections can used according to the needs and characteristics of the equipment where it will installed:
SANTA
It is the same connector type as a traditional hard drive and is used most when replacing an HDD with an SSD. With this type of connection, transfer speeds of up to 600 MB/s can achieved. Externally, these drives are similar to 2.5-inch hard drives and are usually encapsulated in a plastic casing.
NVMe
However, this SSD drive connects directly to a PCI-Express port on the computer’s motherboard, allowing transfer rates of up to 2000 MB/s in reading and 1500 MB/s in writing. Externally, they are very similar to a PCI-Express expansion card, like a graphics card.
PCI Express consists of a high-speed communication bus used to connect devices to the computer’s motherboard directly with expansion slots called PCIe slots for them to communicate with the CPU. It has several uses. One of them is in NVMe SSDs, the fastest we can find, so they require a powerful bus like this.
PCI Express ports connect devices on the motherboard, such as graphics or network cards and hard drives. Most use version 3.0 of this interface, with which an 8GT/s transfer rate can achieved and up to 984.6MB/s speed on each line. Each slot or device can have one line, 2, 4, 8, or 16. Commonly, 16 are used on the graphics card, allowing transfer speeds up to 15.8GB/s or 126Gbps with the 3.0 interface.
Version 4.0 is not as widespread, but it supports twice the bandwidth of the others. It supports twice the transfer speeds. The x16 lines would keep rates of up to 1969MB/s per lane or 31.5GB/s with 16 routes.
