7 best 120GB sSd for laptop in 2021 2.5, M2, SATA, NMVe

I greet you. Today we are going to take a look at the Best 120GB SSD For Laptop. I have included both regular 2.5 ”SSDs and more efficient NVMe SSDs. Basically, all models will be one way or another budget, both the volume is small and the most popular type of memory TLC. Nevertheless, this is not so important for ordinary users who do not care about a high result in server tasks, because in budget SSD controllers are very poorly suited for this. But as a drive for an operating system or storage for games, such SSDs are just perfect.

One of the most affordable SSD drives. It can be bought even cheaper in Russian stores than from China. The connection interface is standard here SATA 3, however, backward compatibility with SATA2 is also provided. And according to some reviews, there is also compatibility with SATA 1, which is a really huge plus and allows you to install this SSD in very old systems, significantly speeding up their work. The Phison PS3111-S11 controller is relatively up-to-date, operates in dual-channel memory access mode. 

At the same time, the read and write speed is not bad even by the standards of more expensive models: up to 500 and 320 MB, respectively. The case itself is extremely thin and made of aluminum, which is why this SSD can be installed even in an ultrabook, without worrying about the fact that it will get very hot.

Nevertheless, there is good development potential here. The total rewriting volume is 75 TB, including DWPD 0.6 times a day. This means that it will be possible to rewrite files with a volume of 77 GB per day on an SSD for 3 years (this is how long the warranty lasts). The result is not bad, especially since under normal conditions the volume of overwriting files is much less, so the SSD itself will be enough for more years. This, of course, depends solely on the operating conditions.

Crucial BX500 CT120BX500SSD1

  • Form factor: 2.5 “
  • Interface: SATA 3
  • Volume: 120 GB
  • Memory type: TLC
  • Write speed: up to 500 MB / s
  • Read speed: up to 540 MB / s
  • Operating time (TBW): 40 TB
Crucial BX500 CT120BX500SSD1

Crucial also manufacture memory cards, but they have long become one of the most popular manufacturers in the SSD market. The price range is budget. The SSD is designed exclusively for home use, without demanding tasks. You can add it to your laptop or upgrade your old system, or add a drive as the main resource for the operating system. True, it does not work as well for Windows 10 as for, for example, Linux distributions. There is a fairly high read and write speed, but still, a low operating time, which leaves 40 TB at DWPD 0.3, while the warranty also lasts 3 years.

That is, the emphasis in this SSD is made not on a high level of rewriting, but on a fast response speed. In other words, Crucial BX500 SSDs are best installed in Ultrabooks that are used as Internet devices. Not suitable for active work with Windows (taking into account constant updates, installations or uninstallations of programs, etc.). In addition, there is an extremely weak single-core controller with no buffer memory support. And this, in turn, greatly affects the operation of the SSD when copying a large number of files with different sizes, because of which the speed can drop by 2-3 times.

Intel 545s Series SSDSC2KW128G8X1

  • Form factor: 2.5 “
  • Interface: SATA 3
  • Volume: 120 GB
  • Memory type: TLC

Intel is mainly engaged in the development of processors. However, they also deal with chipsets, various tablet, laptop devices, and even entire system engineers. The same goes for SSDs. Much less often, but their offers can be found in this category too. Their assortment is not very large, but their SSDs are of higher quality, reliable, and faster, as evidenced by user reviews and actual tests. This is achieved mainly through special Intel technologies. Such as: “Smart Response Technology”, “Rapid Start Technology”, “Remote Secure Erase”. Coupled with a high IOPS, this gives a high result during operation, even if the competitors’ declared read or write speed is higher.

Average operating time – 72 TB. Taking into account the 5-year warranty, the SSD is also designed for a small number of rewrites per day, which means that you should not overload the drive too actively.

Unusual appearance: metallic styling with a logo on the side. The case itself is held by 4 screws (one of them has a seal). The thickness, however, is small and also allows for use in Ultrabooks without any problems.

Transcend SSD 110S TS128GMTE110S

  • Form Factor: M.2

Hard drives have been used in personal computers since the beginning. They, like most components, play a key role. And in the realities of 2019, where most computers already use Windows 10 in one way or another, almost all PC performance depends on the drive. Low RPM notebook hard drives create a bottleneck. That is, due to the low speed of the drive alone, the entire computer as a whole cannot function at full capacity, even if powerful components are installed. Therefore, it is logical to give preference to more advanced types of drives. Currently, SSDs are relevant – solid-state drives without the use of mechanical parts. 

The main ones are microcircuits and flash memory chips. It can be compared with RAM, however, the speeds there are colossally different (RAM is ten times more productive and is arranged differently). However, standard SSDs connected via SATA 3 are also becoming in some sense, not the best choice, since their capabilities rest on the interface itself, the maximum capabilities of which end at around 600 MB/s. Therefore, another method of connection was invented directly, via PCIe, using the NVMe protocol, which allows you to achieve much higher data transfer rates. For this, there is an M.2 connector, you can find it on all standard motherboards that are now being produced (even on the most budget ones).

The advantages of such SSDs over conventional ones are obvious. But this also affects the price, which should be taken into account. But in the case of the Transcend 110S, we can say that this drive is extremely affordable. The memory type is still TLC, the NVMe protocol (that is, the same interface). The write speed is quite modest, only 400 MB / s, however, reading can reach 1600 MB / s, which is already a decent result. MTBF 1.5 million hours with a 5-year warranty. It can be installed without any problems either on any personal computer or on most laptops. At the same time, the memory chips will not warm up much. You should also know that DWPD here is only 0.2, which means that this SSD is not very suitable for the role of a drive that will be actively used. But for home or office use, it fits perfectly.

It is the Best 120GB SSD For Laptop. Another NVMe SSD with higher write and read speeds; 600 and 1800 MB / s. The service life and operating time of rewrites are average, and the warranty is only 3 years. The price range is slightly higher than the competition. This can be explained by a high-quality hardware assembly, which includes a Realtek RTS5763DL controller with 64-layer flash memory, manufactured by Micron (one of the main ones in the entire flash memory market). 

High DWPD 0.4 will allow you to use this SSD for many years in a domestic environment. Ideal for the main drive with Windows 10. It can also be installed in absolutely any motherboard with an M.2 connector, including laptops. It will work, regardless of the irrelevance of the board itself. But in the case of laptops, there can be problems, since they often contain a certain list of manufacturers, with devices that the motherboard can work with (that is, there is a certain white list, it cannot be bypassed). Therefore, you should be careful.

  • Operating time (TBW): 100 TB
  • Service life: up to 1.5 million hours
Gigabyte M.2 PCI-E SSD GP-GSM2NE8128GNTD

Just perfect for an operating system drive. Although it is NVMe, the speed of reading files is a bit low, but it has extremely high MTBF, as well as full rewrites 0.7 times a day, which is the highest value from the entire top. Under such conditions, the service life is up to 1.5 million hours, but it is unlikely in any system that the entire drive will be overwritten so often and in such a volume every day, so you should understand that this option is very durable, although not the most productive. However, it is still 2x faster than standard SATA 3 SSDs.
