What is a SSD ?.
The solid-state drive, SSD, is a flash disk that allows you to backup your data and improve the performance of your computer.
Unlike the traditional hard drive (HDD), which is mechanical and works with the read heads, the SSD uses the RAM and other components in your PC to access your data, store them and organize them.
SSDS are known to be shock resistant (perfect in case you drop your laptop), energy-efficient, silent. And, they are especially known to be much more durable and fast than an HDD.
In fact, the SSD launching applications, software, web pages and copy the large files almost instantly.
How much does a SSD ?.
SSDS are considered as computer components to full-fledged and they are now sold at affordable prices.
It is possible to find SSD 250 Gb of storage for around 100 € and for double the storage space, add about 150 €.
Admittedly, this is more expensive than a HDD, but you can use them in conjunction. Install Windows and the software you use most on a solid-state drive ; store your files (photos, music, etc.) on a HDD, where speed of execution is of little importance.
What SSD to choose ?.
There are two main interfaces for SSDS, the SATA and PCIe (PCI Express).
The SATA is probably the most common. It is found on most computers and laptops, where it is used as connectors for hard disks or CD/DVD drives.
The SATA SSD usually has a format of 2.5 inches (about 6 cm), this size is specially designed to fit the portable PC. It is also compatible with computers fixed the most recent.
Laptop users should pay particular attention to the dimensions of SATA, because some of them have a thickness of 9.5 mm and other of 7 mm.
The PCI Express (PCI‑e) replaces the SATA interface and it offers a flow rate two to three times higher than its predecessor.
What is referred to by the acronyms NVMe and M2 ?.
NVMe (Non-Volatile Memory Express) is the standard which complements the antique AHCI (Advanced Host Controller Interface).
The NVMe is used to make the link between the PCI‑e and the motherboard of your computer. This protocol is capable to manage more than 60,000 orders against 32 for AHCI.
M. 2.is a new connector that is found on the cards-mother’s last generation, and on a couple of laptops.
Most of the M. 2 type 2280, in reference to their dimensions (22 mm width and 80 mm length).
To find out if it is compatible with your PC, refer to the manual for your motherboard or contact the manufacturer of your computer.
Note that this is not because an SSD is equipped with a connector M. 2 it adopts the mandatory standard NVMe.
Also, it is possible to find a SATA SSD with a connector M. 2, but which are limited to a SATA interface speed. So look at these features before making any purchase.
If your motherboard is incompatible with the technology Mr. 2, you can purchase an adapter card PCI-e, to around 10 €.
Also, be aware that some SSD M. 2 can be sold with or without an adapter, like the KC2000 of Kingston.
For performance, the SATA SSD with the fastest read speed of 550 Mb/s while the SSD PCIe interface, NVMe read more than 3 000 Mb/s.
What about the features of MLC, TLC and SLC ?.
Acronyms, MLC, TLC and SLC refer to three types of flash memory.
The TLC is a cell at three levels (Triple-Level Cell), it is the least expensive of the architectures, the MLC is multi-level (Multi Level Cell) and SLC (Single-Level Cell) has only one level, it is the most expensive on the market. Rather, it is meant for businesses.
Their differences lie in their life time and in the amount of bits (data) that each cell can store. TLC stores 3 bits of data, the MLC 2-bit and the SLC one.
The greater the amount of data per cell, the higher the SSD will be subject to reading errors. Its performance and its lifetime decrease.
It is also necessary to take into consideration the warranty of the SSD, especially if you give much importance to the safeguarding of your data, and take account of its write speed (expressed in terabytes written, ToW/TBW).
Similarly, it is good to know that the power of some of the SSD may change depending on whether they are active and that your computer is in sleep mode or not.
1. Corsair Force Series MP510 .
The MP510 is good on all fronts : performance, speed, storage capacity (120, 240 or 480 Gb) and price.
It is compact, very fast and can backup 240 Gb to 2 Tb of data.
For a product of this quality, the SSD MP510 has a price defying any competition.
2. Kingston KC2000 .
The power of the SSD KC2000 M. 2 NVMe the place into a veritable competitor in the face of big brands like Samsung and Corsair.
If you have a SATA hard drive, then you notice the difference in performance and throughput. The SSD KC2000 Kingston has a nice balance and it is almost as fast as its rivals.
Using a controller 3.0 x 4 last generation its write speed is a maximum of 3 200 Mb/s and read is about 2,200 Mb/s, it therefore delivers a very nice endurance. In addition, it is a model with automatic encryption that allows you protect your data.
If a capacity of 250 Gb is not enough for you, then the brand offers three others, one of 2 Tb.
Great benefits at a very affordable price makes this SSD KC, 2000 an excellent choice.
3. Crucial MX500 .
The Crucial MX500 is a very good SSD for those wishing to increase their storage space.
We appreciate its functionality Integrated Power Loss, Immunity, which allows you to preserve data on, for example, a power outage.
Unless you need an SSD 4 Tb or edit daily videos Ultra HD, we find that the MX500 combines almost perfectly cost and endurance.
It is also available in format M2.
4. Samsung 970 Evo More .
The 970 Evo More is in addition not unusual in the range SSD from Samsung, and it is welcome.
Yet, more efficient than the 970 Evo, it costs about the same price. If you are looking for a SSD NVMe of very good quality, so do not hesitate and opt for this model.
On the other hand, if you want to save a few euros then there is the Corsair MP510, at the best price‑quality ratio.
5. WD Black SN750 .
Price level, SN750 certainly cannot compete with a Corsair MP510, but it is a M. 2 SSD very efficient with storage capacities up to 2 Tb.
6. WD Blue 3D NAND .
The disk WD Blue 3D NAND is the best SATA SSD (before the technology NVMe sent it to the dustbin).
This SSD far outperforms its predecessor and it has enough to become a serious rival to the Samsung models and Corsair’s mid-range. The WD Blue 3D is a disc that knows how to ally performance and attractive price.
The only thing we regret is that it does not allow for automatic encryption of data.
7. Kingston KC600 .
The Kingston SSD KC600 is as fast as the excellent Samsung 860 EVO but cheaper.
It combines a form factor 2.5-inch interface SATA III with backward compatibility. In addition, it incorporates the latest in 3D technology TLC NAND 96 layers.
Sides performance, this drive can reach 565 Mb/s read and 520 Mb/s write and up to 90 000/80 000 IOPS 4K playback. In addition, it can store 256 Gb, 512 Gb, 1024 Gb, or 2048 Gb of data.
With his update kit, you’ll have no trouble to install it.
8. Samsung 970 EVO .
In general, the Samsung 970 Evo is not only better than the 960 Evo, but it also beats the 960 Pro.
It has more IOPS (operation of input-output per second, which can reach 500 000), and write faster.
If you can buy the SSD Samsung 970 Pro (from 195,89 €), so do not hesitate, otherwise the Samsung 970 EVO is very much the case.
9. Samsung 860 Evo .
This SATA is very suitable for those whose motherboard is incompatible PCI M. 2 (NVMe) ; the other can turn to the Samsung 960 Evo.
The 860 Evo is not particularly more energetic than its predecessor, the 850 Evo), but it has a longer shelf life.
10. Kingston UV500 .
This may not be the fastest solution or the least expensive, but the UV500 is a very good option for all users who want an SSD very solid.
It is a disk self-encryption based on the AES hardware encryption 256-bit. It secures your data in an optimal way. It is compliant to TCG-Opal 2.0 and in agreement with the RGPD.
It lends itself equally well to use personal or professional.
