When it comes to choosing the best SSD, there are a lot of factors to consider. Factors such as cost, performance, and storage capacity all play a role. But when it comes to choosing the best SSD for your computing needs and your wallet, there’s one factor you shouldn’t overlook: speed.

After all, how many things do you need to run on your computer at once? That’s why the answer to this question is simple: the higher the speed of your solid-state drive (SSD), the better. The issue with most external drives is that their read and write speeds are limited by their enclosure and not their controller. This means that not only will a slower enclosure limit how fast an SSD can operate but also that if you want faster speeds with your enclosure as well, you'll have to upgrade both separately. In other words, upgrading just the SSD isn’t enough if you want to maximize both capacities of your new drive.

You are strongly encouraged to pay close attention to the Crucial BX500 2TB 3D NAND SATA as our top product. Or you can check the Western Digital 500GB WD Blue 3D NAND as the other great option, even if the first option didn't meet all of your requirements.

Based on what people and technical innovation have co-operated to analyze and build the following qualities, it’s helpful to look into lots of them:

SSD Form Factors And Interfaces

In 2005, laptops had internal SSDs that were connected to their motherboards via a SATA III interface. This is the same connector as an internal hard drive. Today, motherboard connections are faster. PCI Express SSDs are now a substantial part of the SSD market.


It matters a lot what type of NAND is used in SSDs. What is NAND, you ask? The non-volatile flash memory NAND, also known as non-volatile Flash Memory (NVM), is not powered to store or retain data. Digital cameras, flash drives for smartphones and SSDs use NAND flash memory to store data. NAND can be classified into three types: Single-level cells (SLC), multilevel cells (MLC), enterprise-level MLCs (eMLC), Triple-level Cells (TLC), Redundant array of Independent NANDs (RAIN), as well as the 3D vertical NAND (3DV-NAND).


The system RAM can be used as a cache byer drives, surely? Although there are some advantages to the HMB method over using no cache, it still doesn't offer the same performance as drives with a cache. HMB is a compromise in terms of performance. The random R/W performance of SSDs with DRAM-less SSDs is better than SSDs without DRAM. However, overall system responsiveness and speed are not as good as SSDs equipped with onboard caches. The choice between cost and performance is the key. To help you make the right choice, check out this list of top NVMe SSD manufacturers.
HMB employs the NVMe protocol instead of PCI Express. This means that it can't be used on SATA SSDs.


Flash memory is limited in life span. This means that once a storage cell has been written more than a specified number of times it will cease to hold data. Drive manufacturers often indicate the drive's endurance rating in total terabytes (TBW) or daily drive write (DWPD).
You should avoid QLC drives if you intend to use your drive longer than this or if you are certain that you will be using the drive more often than average. Instead, look for models with longer warranties and higher endurance ratings.

SSD Storage Capacity

What size SSD should you have? What amount of data are you looking to save? The best SSD storage capacity will depend on the use scenario. SSDs are available in a range of sizes, from 256GB to 2TB. The cost per gigabyte is generally lower as drives become larger. A 250 GB SSD is a common configuration on desktop computers. It stores the main productivity apps and operating system. A larger HDD is used to store work files and media. SSD storage costs have dropped to a point where all-SSD storage makes sense for many use cases.

DRAM Cache

The drive must know exactly where the data are stored within the memory cells when the SSD is instructed by the system to retrieve it. The drive maintains a "map", which tracks all data stored physically. The drive's DRAM Cache stores this "map". The cache, which is an additional high-speed memory chip within the SSD that can be very important, is separate. This type of memory performs faster than separate NAND Flash within the SSD.

SSD Reliability And Lifecycle

Common reliability ratings for SSDs are the average time between failures. This is a complicated concept. Wikipedia describes it as: MTBF stands for the time that is predicted between failures in an electronic or mechanical system. This can be used to describe normal system operation. We'll now discuss what it actually means.
MTBF ratings can be found in millions of hours. MTBF ratings of 1.5 million hours don't necessarily mean your SSD will last for 1.5 million hours. This is over 170 years. Instead, MTBF measures the probability of failure when there is a large number of drives.


It is clear that SSDs without DRAM caches are not the best for performance. Although HMB is a great way to improve performance, these workarounds can still lead to compromises. If you're looking for an affordable NVMe SSD with HMB, there are some options available that can offer more features than drives without DRAM cache. The performance loss may not outweigh the savings, especially if you're using the SSD as a secondary drive. Avoid buying a DRAMless SATA SSD in all cases.

Memory Controller

A SSD does not contain NAND flash memory cell cells. Each SSD has a controller chip, which manages memory cell data and connects to other parts of the computer such as the motherboard or other data storage devices. Many of the most important features in SSDs are handled by memory controllers. These include wear-leveling and data provisioning. The type of memory controller you use can have an impact on drive performance, reliability and endurance as well as other features.

Drive Performance

SSD and hard drive shoppers often pay attention to SSD throughput, which is commonly referred to as the maximum read/write speed. This factor plays a significant role in driving SSD performance. Although read/write speeds do impact the speed at which files are written and received from the drive, they do not affect performance. When transferring large amounts of data onto or from the drive, read/write speeds are important.


What Is Wear Leveling?

The repeated erase and program cycles in Flash Translation Layer (FTL) and data storage systems can cause NAND flash memory to become worn. The memory becomes invalid if it is constantly programmed and erased to the same location. The NAND flash will therefore have a short life span. Special algorithms within the SSD are called wear leveling to prevent such scenarios. Wear leveling, as the name suggests, is a way to distribute program and erase cycles evenly across all memory blocks of an SSD. It prevents the repetition of program or erase cycles within the same block. This results in a longer life span for the NAND flash memory.

Why I Might Notice A Decrease In Write Performance When I Compare A Used Drive To A New Drive?

SSD drives can be used in environments where there is a greater number of writes than reads. MLC drives often include an endurance management system to ensure that drives last for a certain period of time. The drive can use an endurance management mechanism to reduce the write speed if it projects its useful life will be shorter than the warranty.

Why SSD?

Solid-state drives use NAND chips to replace spinning platters for data storage. HDDs are susceptible to damage due to their many moving mechanical parts. Solid-state drives on the other side have no moving parts, so they are much more resistant to damage, even if they get impacted.
SSDs deliver ultra-high performance input/output operations per second (IOPS), and very low latency for transaction-intensive server and storage applications. They can be used with HDDs to reduce the total cost of ownership (TCO), as they are low in power and operate at low temperatures.

What Are The Types Of SSDs?

SSDs (solid-state drives) that are based on flash memory typically have lower latency than hard drives, which can often enable faster response times. SSDs offer higher throughput than HDDs for random-read workloads.
Based on Nand Flash : SLC, MLC (Multilevel Cell), eMLC [enterprise MLC].
Basing on the Host Interface, SATA SSD and SAS SSD

How Long Can I Expect The Drive To Retain My Data Without Needing To Plug The Drive Back In?

This depends on the amount of flash used, P/E cycle used and type of flash. This can vary between MLC or SLC. In MLC it can range from 3 to 10 months, while in SLC it can go up to more than 10 years. Retention is affected by temperature and work load.

How Do SSDs Maintain Data Integrity?

The following methods are used to maintain data integrity on Dell SSD drives:
- Strong ECC
- Protection of data path and CRC
- Multiple metadata and FW copy
- Metadata checksum protection
- Strong voltage rail design ensures stable power for NAND flash memory

What Are The Best Use Cases & Applications For SSDs?

SSDs work best for applications that need the most performance. SSDs are best suited for I/O-intensive apps such as data mining, data warehouse, data mining and analytics.
SLC SSD is the best technology to write cache and for read caching applications that are write-intensive and random.
MLC SSD is becoming a preferred choice for handling both writes and reads. This makes it especially attractive when you have tight budgets.
MLC SSD offers the best value for expensive read-intensive tasks such as accessing databases tables.

How Is SSD Sanitized?

SSDs can easily be cleaned by writing several times over their entire capacity. For future releases, Dell is investigating secure erase and self encryption features for SED SSDs. This allows for a quicker and more efficient method to clean a SSD.

How Is The SSD Useful Life Span Calculated?

Three key factors determine the useful life of SSDs: SSD NAND flash technology and capacity. The application usage model is also important. The following calculator will give you an idea of how long your drive will last.
Life = [years] = [Endurance (P/E cycles] * Capacity (physical, bytes]* Overprovisioning Factor). / Write Speed [Bps] Duty Cycle [cycles] *Write % * WAF. / 36 *24*3,600
