Choosing the Best SSD

It is difficult and tricky for some users to make a decision about selecting the best SSD. Because a good SSD is essential for your system to boost its performance. In today’s market, SSDs are available in different varieties from sizes, capacities, performance to its prices. Furthermore, when you are buying the best solid state drive, you should also take its compatibility and lifespan into consideration.

Hence, if you want to buy the best SSD 2021 for your PC or laptop but you are unable to choose the right one. Then read our guide carefully because we have listed some of the important factors that will help you in purchasing the best ssd drive.

Types of SSDs

There are different types of SSDs available in the market. They are different in size, storage, speed, and price. Now it depends on you, which type of SSD you want to buy according to your budget, and whether it is compatible with your laptop’s motherboard or not?

Below are some of the important types of SSD.

SATA

SATA is an interface connector used by SSDs for connecting the system with the SSD.
To connect the laptops or desktops with SSDs, it needs a connection interface. SATA is an interface connector that provides the interface connection. SATA is known as the old two-connector system. SATA-based solid-state drives are best for older laptops and desktops that lack the newer SSD connector types. The performance of SATA SSDs are good as its file transfer speed is 4.8Gb/s (600MB/s). So, If your system supports this type of SSD then you will find it at an affordable price.

PCIe

If you want an SSD that is fast and offers better performance and also you are not price-conscious then the best choice for you is PCIe (Peripheral Component Interconnect Express). It supports 1X, 4X, 8X, and 16X lanes whereas its transfer speed per lane is up to 985MB/s. Furthermore, NVMe (Non-Volatile Memory Express) is the best choice than AHCI (Advance Host Controller Interface) because NVMe is specifically designed for PCIe solid-state drives. And the AHCI was designed both for SSD and HDD a while ago. Also, the performance of NVMe is much better than ACHI.

M.2

M.2 SSDs are a work of art and are superior to all other types of SSDs. M.2 SSDs give high speed and performance. These small SSDs in size are specifically designed to be fit easily in slim devices like notebooks and tablets. Besides, its speed is up to 4GB/s. Apart from its speed, it also supports SATA 3.0, NVMe 3.0, and USB 3.0. The best M.2 SSD comes in three types of keys and their price is also different from each other. The keys are “B”, “M” and “B+M”. The “B” keying pins (12-19) offer 2x lanes, the “M” keying pins (59-66) offer 4x lanes bandwidth while the “B+M” keying pins increase the compatibility of both the slots.

Form Factor or Physical Size

If you want to purchase an SSD for your laptop or PC then you should check the size or form factor of the solid-state drive. The form factors show whether the SSD will fit into the chassis of your system or not. We have described below the popular form factors and also how they are dissimilar from each other not just in dimensions but also in other aspects.

2.5 inch Form Factor

It is one of the common sizes for SATA SSD. The physical dimensions of 2.5 inches SATA SSD is the same as that of 2.5 inches hard drive used in laptops or desktops. Though the 2.5 inches hard drives are heavier than the 2.5 inches SATA SSD. A 2.5 inch SSD can be used in desktops and laptops.

M.2 Form Factor

M.2 is a small form factor for SSDs. These solid-state drives are available in different sizes that are 2280, 2260, 22110, 2230, and 2242. In this, the first two digits show the width in millimeter and the other digits show the length of SSD in millimeter. 2230, 2242, and 2260 are very compact form factors but only a few solid-state drives are available in these sizes. The most common and popular form factor is 2280. Most motherboards support up to 2280 form factor.

The M.2 SATA and NVMe PCIe SSDs are available in the M.2 form factor. Also, for differentiation between these two, the M.2 SATA solid-state drive has two notches at the connector end and the M.2 NVMe has one notch at the end of the connector. M.2 solid-state drives can be used in laptops, and desktops if their motherboard has an M.2 slot and also supports the M.2 SATA or NVMe SSDs.

mSATA Form Factor

mSATA or Mini-SATA solid-state drive is a small and old form factor that has been replaced by the M.2 form factor. It can be used in laptops through the mSATA slot. It has a width of 30mm and a length of 50.95mm. The mSATA drives are rare nowadays but if your laptop has an mSATA slot, you can buy and use it on your laptop.

Speed

If you want optimal performance then you should buy the fastest SSD but such a solid-state drive comes with a price. When it comes to speed or performance than the NVMe SSDs are much faster than the SATA SSDs. The PCIe 3.0 NVMe SSDs are six times faster than the fastest SATA solid-state drives. The sequential read speed of PCIe Gen 3 NVMe SSD is up to 4000MB/s and write speed is up to 3500MB/s. On the other side, the read and write speed of SATA solid-state drives are up to 550MB/s and 520MB/s. Moreover, the PCIe Gen 4 NVMe SSDs are 40% faster than the PCIe Gen 3 NVMe solid-state drives and have the read and write speed up to 5000MB/s and 4400MB/s. But you should note that such the fastest SSDs are expensive and you have to spend some money to upgrade or replace your old hard drive.

Storage

Storage capacity is the most important thing for a user after the speed of the SSD. Nowadays you can find an SSD with a storage capacity of up to 4TB. Though, the price of SSDs remains high when compared with hard drives of the same size. You can also find 128GB, 250GB, 500GB, 1TB and 2TB SSDs. Now it depends on you how much storage capacity you want for your system.

Lifespan

The SSDs have a limited number of writes. It means that data can be written or rewritten to a limited period on SSD and when it is over, you may face data corruption. Generally, the lifespan of an SSD is expressed in the TBW rating. The TBW rating stands for Terabytes Written or Total Bytes Written. If you buy an SSD having 100 TBW rating then it means that you can write up to 100 TB data on it over time. So, when you are purchasing an SSD, you should look for the lifespan of it.
