Buying Guide for Best SSD

Almost every solid-state drive (SSD) you can buy today is a guarantee but some are better than others. If you need to buy an SSD, you will surely be wondering what SSD is the best for the moment. Well, we can help you find the answer!

Careful reading of this article will make you understand the undoubted benefits of mounting an SSD to accommodate only the operating system and the programs
Hard drives are undoubtedly one of the most important components in the PC because of the task they are doing: they are devoted to the actual storage of all data , from the operating system to all your personal data (photos, videos, files, music and more ).

While traditional hard drives go for ever higher levels (now in the TeraByte order), a new technology flanked a few years in the archiving market, a technology capable of doubling (in many cases tripling) the ability to read and write the fastest hard drive produced: the solid state disks (SSD).

Careful reading of this article will make you understand the undoubted benefits of mounting an SSD to accommodate only the operating system and the programs. So how do you figure out what is the best SSD? After examining the theoretical part, we see what are the best SSDs on the market.

Why an SSD?

If you have a computer with a mechanical hard disk, it’s probably the slowest part of your system. All you need to do is access data to your hard drive: even booting or shutting down your system, saving and loading files, starting a game or rendering a video will be much faster on a SSD .

Unlike traditional hard drives, SSDs are much less prone to mechanical failures. In fact, they are better than hard disk drives in almost every aspect. They use much less energy, they emanate less heat and do not vibrate. SATA SSDs are three or four times faster in reading and writing data; PCI Express drives are up to seven times faster.

More importantly, SSDs are particularly fast in random access to stored data. A mechanical hard disk must physically move a magnetic head from a specific point on the rotating disk to read the data, and this usually takes about 17 milliseconds on the fastest drives. An SSD, which has nothing to move but only moves electrons, can do it in less than 0.1 ms.

The only areas where hard drives are even higher than SSDs are price and capacity . But the price gap is shrinking, at the same time people are keeping more data in clouds and less on their computers.

SSD: what to know before buying

Before purchasing, it’s important to understand what type of SSD fits your computer. At present, there are two different data transfer interfaces (SATA and PCIe), two different transfer protocols (AHCI and NVMe), four different physical connectors (SATA, mSATA, M.2, and PCIe) and four different Form (2.5 inches SATA, mSATA, M.2 and full-size PCIe).

Here is a quick breakdown of terminology:

SATA: refers to both the physical connection type and the transfer protocol. The physical connector is used by 3.5-inch and 2.5-inch hard drives, as well as most SSDs. If you have a desktop PC or larger laptop, you may want to consider purchasing a 2.5-inch SATA disk. SSDs that use SATA protocol also exist in much smaller form factor and are mSATA and M.2 , which have a different physical connector. The current SATA III standard has a speed limit of approximately 600 MB / s. Unless you have a PCIe M.2 or full-size PCIe on your PC, you can not get an SSD that is faster than this.

PCIe: is a faster interface that can transfer data to up to 985 MB / s transfer speeds. Most SSDs PCIe use a four-lane (4x) interface, which adds up to a maximum speed of 3.940 MB / s, about 6.5 times faster than SATA drives. PCIe drives are available in M.2 and full-size PCIe versions. Full-size SSD PCIe should work on most recent desktops; Some older desktop motherboards and almost all ultrabooks use M.2.

M.2: This is a type of physical connector used for SATA SSD and PCIe. M.2 drives are much smaller than 2.5 inches SATA drives and are used in most ultrabooks and high-end desktop PCs. SSD M.2 are available in a variety of sizes but M.2 2280 (22 mm wide for 80 mm in length) is the most common. When purchasing an M.2 disc, it is important to ensure the right kind of interface and size.

NVMe: This is a new interface protocol for PCIe drives, replacing the previous AHCI protocol used with SSDs and hard drives. Designed from scratch to work with SSDs and other flash memories, it allows for faster read and write speeds. Most PCI SSDs now use NVMe.

MSATA: Units have been used in many ultrabooks and handhelds before the M.2 standard became common. Most new laptops use M.2 but many ultrabooks with mSATA ports are still in use.

If you have a laptop, it is advisable to visit the manufacturer’s website or use system tools to figure out what type of SSD supports your device.

Best SSDs: Which to buy?

It depends on what you want to do with the PC , in theory any model is fine. But if we just have to choose carefully here, the SSDs are suitable for the most common requirements among those presented above. For each SSD that we propose below, there are cuts from :

  • 128 GB
  • 256 GB
  • 512 GB
  • 1 TB

You can therefore choose the product according to your personal needs.
