Buyer’s Guide

If you don’t know much about computers and still want to purchase an SSD, then you should get the help of a buyer’s guide. Knowing the function and various aspects of SSDs would help you determine the quality of various products in the market. 

How Do SSDs Work?

The operation of Solid State Drives is quite destructive as it is burnt up to a certain degree every time it is written to a NAND flash chip. But these are precisely manufactured silicon devices that can withstand these effects. Drives built with these chips are highly durable than hard drives that perform the same workload. They are also faster and much compact than hard disk drives. SSDs can be trusted with your data than other devices. The lower power consumption of SSDs makes them ideal to be used in laptops and computers.

What to Look for When Buying an SSD?

Here are some important factors that you should look for in SSDs. Knowing all about them would help you to find the best device.

Drive Capacity

Different brands in the market have their ranges of capacity and different prices. The general storage capacities range from 128GB to 8TB. According to your requirements, you can choose the ideal capacity you need.


The performance of the SSDs relies typically on the performance of NAND chips and SSD controllers. The SSD controller is a computer system that has the responsibility of transferring data in and out of the flash chips of the SSD. The performance varies just as in any other computer comparison. The controller is working when the driver reads, writes, and erases. So having a high-performance controller would help you to avoid bottlenecks in the performance of your SSD.

P/E Cycles

The Program Erase Cycles are the number of series events where the data is written, erased, and rewritten. This is done in the amount that can be handled by the NAND flash chips. The higher the number of cycles, the better. The best SSDs have from 500 to 100,000 P/E Cycles.

Error Correction Code (ECC)

Error Correction Codes and detection mechanisms are used in modern SSDs. It helps in protecting data stored in NAND flash chips and avoids any corruption. So finding an SSD with proper ECC support is essential.

Meantime Between Failures (MTBF)

MTBF is a measure of the reliability of components. Not only for SSDs but this can also be applied for any device that wears out with time. So generally, MTBF is more like the life expectancy of an SSD. As advanced technology is used in the manufacturing processes at present, the MTBFs are offered over million hours. So when purchasing an SSD, make sure to find one with the highest MTBF.

Trim Support

Trim support helps in cleaning and optimizing deleted files to help SSDs function constantly over a long period. This is done automatically by the operating systems in modern software. So if you are purchasing an SSD for a PC with an old operating system, then make sure that the SSD you buy has an internally supporting trim feature.

NAND Technology

Four types of NAND cell technologies are used by SSDs. They have different arrangements along with pros and cons. They are:

  • SLC (Single-Level Cell)
  • MLC (Multi-Level Cell)
  • TLC (Triple-Level Cell)
  • QLC (Quad-Level Cell)

Hardware Interface

A built-in ACHI compatible SATA controller is available for the standard-sized 2.5-inch SSDs. NAND memories have very fast speeds, but the speed of the 2.5-inch form factor is limited to the maximum speed of the SATA controller of the motherboard. Currently, the SATA interface is on version 3.0, which has a maximum transfer rate of 6 Gb/s. Yes, it’s gigabits per second and not gigabytes. So with the encoding, the high clock speed of the SATA signal stable is around 500 MB/s.

Form Factor

The compatibility can be determined by the form factor of the SSD. The 2.5 inch SSD can give the best of 500 MB/s, and you would have no option. If you own a laptop with a SATA drive without an M.2 slot, then you would have to purchase a 2.5-inch drive. However, you can have the advantage that M.2 and PCIe drives are much faster.

Warranty and Support

As there are various qualities of SSDs in terms of their build and performance, they cannot be treated equally. So when buying an SSD, make sure to go for the latest technology made by a renowned manufacturer. This would ensure better performance and a longer lifespan of the device. You should also go through customer reviews and feedback before you purchase it. The best high-end brands are from reputed manufacturers such as Toshiba, Samsung, and Silicon Power.

Frequently Asked Questions

Frequently Asked Questions about SSD

Which type of SSD is fastest?

PCIe SSDs have more bandwidth and can provide three or four times the speed and performance of SATA. So these are considered to be the fastest type of SSDs.

What is the lifespan of SSD?

The theoretical age of an SSD would be around 10 years. But the average life would be shorter than this due to working conditions.

What should SSD avoid?

  • Don’t defragment the SSD. 
  • Don’t wipe the SSD drive. 
  • Don’t use old operating systems such as Windows XP or Windows Vista.
  • Don’t disable TRIM. 
  • Don’t fill an SSD to its full capacity.
  • Don’t write to SSDs constantly.

How many times can SSD be rewritten?

According to the lifespan of a maximum of 10 years, an average SSD can write approximately between 3,000 and 100,000 times.


SSDs have become a popular choice over hard disk drives due to various reasons, such as faster data transfer speed and efficiency. But choosing the best product may not be easy as their qualities differ widely. So in this guide, you must have had a proper idea about the SSD brands to avoid. If you know all the important aspects of them, you can choose a good SSD reliability by brand.
