Samsung 860 EVO

New Best-selling Family Member

The EVO series is the most popular SSD series not only among Samsung models but in general throughout the industry. That is the result of the company's work on constantly upgrading their product range as well as their flexible pricing policy: with innovations being released as often as at Samsung, the previous versions slightly decrease in price, thus becoming harder to compete with for other companies.

The Samsung 860 EVO is based on an MLC V-NAND Flash. MLC drives are the best option for general consumers today: if you are looking for the fastest solid state drive for your gaming computer, for example, you probably need an MLC SSD. While SLC models a faster still, they are not found among consumer-level options and are geared towards enterprises. Though MLCs are a bit on the expensive side, mostly, they are worthy of the price in the long run.

The drive is offered in several capacities: 250 GB, 500 GB, 1 TB, 2 TB, and 4 TB. All of them offer the reading speed of up to 550 MB/s and the writing speed of 520 MB/s. The speeds are higher than the previous models thanks to the TurboWrite technology. This technology also provides a larger buffer that enhances the performance of the SSD. For example, the buffer size for a 1 TB drive is 42 GB.

Review of Samsung 860 EVO 2.5 Inch SATA III Internal SSD

The Most Reliable SSD

Another remarkable spec this model is carrying is its TBW, the terabytes written. It is 150 TB for every 250 GB of capacity and is only topped by the Samsung 860 Pro. 150 TBW for every 250 GB means that, if you choose a 1TB drive, you get 600 TBW, and with a 4 GB drive that number rises to no less than 2400 TBW. That's actually very impressive, no competitor comes close to these at the moment.

The 860 EVO is faster, more reliable than its predecessors, and it also consumes less energy: 2.5 Volts as compared to 3.3 Volts of a previous model. Furthermore, it is equipped with an MJX controller, which, in its turn, works nicely with a DDR4 memory that is also known to be a low-consumption one.

The drive comes with the Magician software for monitoring it and the access to a tool for migration. The Magician is rather difficult to manage but it does offer a couple of useful features if you are ready to spend some time mastering it.

Drawing a conclusion, we'd say that this model is an undeniable winner when it comes to constant heavy loads, like with professional gaming or some similar activity. Its main selling point is durability, after all. If you use your PC more moderately, the price difference between this and some other models might not be worth it. Consider your needs and maybe check out other suggestions in this review before you decide.

P.S. This internal SSD is compatible with some ancient systems, like Windows XP with service pack 2, for example, released almost 15 years ago, in August 2004. Rare as it is nowadays, some computers still have this OS version and not many solid-state drives are capable of working with something released this much earlier than they were.

Western Digital Blue (WDS500G2B0A)

WD's Breakthrough Model

The WD Blue is one of the most reliable SSD devices, with its Mean Time To Failure (MTTF) bordering on 1.75 million hours. That's almost 200 years of operation, can you imagine that? Of course, the actual lifespan depends more on the drive use and, therefore, such parameters as TBW (Terabytes Written) and DWPD (Drive Writes Per Day) but the sheer number of 200 years is still impressive.

As of 2016, Western Digital (shortened to WD) is a parent company of SanDisk, which means they have similar, if not the same, technologies used in their products. Particularly in this solid state drive, WD has implemented the 3D NAND TLC flash created for them by SanDisk. The drive has 200 TBW and approximately 0.22 DWPD for 500 GB of capacity, which is not something we'd consider too over-the-top but is really good for the price and the 5-year warranty. The price is, by the way, exceptionally moderate, low even, all things considered.

Basically, at a price below $100 for a 500 GB SSD, you get the near-top reading and writing speed SATA interface can offer: 560 MB/s and 530 MB/s respectively. Some testers claim the drive even exceeds them, if only slightly to the point of being unnoticeable during the actual use.

Review of Western Digital Blue (WDS500G2B0A) SATA III 3D NAND SSD - 2.5" Solid State Drive

Top Average User Bargain

This solid state drive for your desktop computer is a real energy savior: compared to its predecessor, the traditional non-3D WD Blue, this one consumes 25% less energy while performing way better.

The WD Blue 3D NAND internal SSD has been subjected to extensive testing by the company's labs to ensure that it works with basically any system without so much as a glitch. It also comes with the access to download the WD Dashboard, a free monitoring software with all the necessary tools for the drive management, including the Acronis True Image WD Edition that allows cloning the system. There is a catch here, though, and it is that this cloning tool, in particular, seems to only cooperate faultlessly when your regular hard drive is also the model from Western Digital; however, there seems to be no problem with all other tools and the general monitoring of the WD Blue drive.

This is the drive primarily for those wishing to upgrade to better manage their everyday computer-related tasks. It is not a gaming or video editing model, at least not for anything hardcore, but it does offer high quality, endurance, and better-than-nice speeds for just about anything else at a somewhat ridiculous price.

Crucial MX500 SATA III

Unexpected Breakthrough

For the first time in a while, the Crucial brand is closing on the industry leaders, the Samsung SSD, not overcoming them yet but after the years of producing drives for lower tiers, their MX500 solid state drive wins in the price department against EVO 850, for example, so much that the differences in performance can be overlooked as not too substantial.

This MX500 is equipped with a 64-layer TLC 3D NAND which has elevated the performance a healthy 30% compared to the 32-layer 3D NAND; the contrast with the planar NAND is even more stark. This drive is faster and more durable, with 360 TB endurance for a 1 TB drive and 700 TB for a 2 TB one. While EVO 860 has 600 TB for the 1 TB drive, winning hands down, the EVO 850 only offers 150 TB there. That's something to consider if you are looking for an SSD to use under some load but aren't willing to cough up more than $200 for 1 TB.

The Crucial SSD offers 560 MB/s sequential reading and 510 MB/s writing speed. Both numbers are more or less average for the class. At the same time, the model shows a top performance in random reading, which is a good thing.

Crucial sells their MX500 solid state drive in four capacities: 250 GB, 500 GB, 1 TB, and 2 TB. The model is not the cheapest on the SATA market but is cheaper than models from more famous brands that offer near-similar performance.

Review of Crucial MX500 SATA III 3D NAND 2.5 Inch Internal SSD

Safe as They Come

The MX500 solid state drive offers top-notch data protection in a case of a power loss. The feature was present in the MX series before but now it has been slightly adjusted to enhance the protection quality by reducing power requirements to maintain the signal.

Here's more. While most TCL drives use SLC buffers, the one designed by Crucial here is dynamic instead of fixed. This means its capacity is flexible: it depends on how much data there is on the flash. When the SSD is in its idle period, the technology frees some capacity that will be used when the speed-up time comes. This way, your drive writes data faster and better.

Included with the drive is the Storage Executive software. This is a collection of tools to manage your MX500. In addition to the standard set of tools, there is a tool to up the overprovisioning, i.e. allocate some more space for the controller's background operation. This will result once more in the performance boost of the drive in general.

We've stated this at the beginning of this review but it won't hurt to repeat: the Crucial's MX500 is not the very best among the drives on today's market but its performance exceeds expectations for the devices of its price so the deal is more than nice in the end.

Silicon Power A55

Made To Last

One of the realities of life with any mass storage device, including SSDs, is the problem of bad sectors. Although they aren't always guaranteed to start showing up, when they do, it usually starts to spell trouble for the data stored on that sector, as well as for the drive on the whole. Recovering from bad sectors can always be quite difficult, especially if the data was corrupted beyond repair, and trying to do this can be a time consuming process. Although SSDs don't experience bad sectors as often as physical hard drives, they do still crop up from time to time.

The Silicon Power A55 2.5 Inch SATA III Internal SSD was made with this problem in mind, and it offers a unique solution to it. This drive features Bad Block Management Technology, which carefully monitors disk space for damaged blocks and, if found, correctly replaces them with working sectors that are reserved for such a purpose. Although this can potentially shorten the storage capacity of the drive by up to 5%, it is a unique solution to the problem of bad sectors, letting you maintain data integrity over the lifespan of the drive without bad sectors causing a serious disruption. Such a feature is always welcomed by anyone who has had trouble with bad sectors on their mass storage in the past.

Review of Silicon Power A55 2.5 Inch SATA III Internal SSD

Plenty of Included Tools

There are plenty of other features of this high speed SSD other than its ability to handle bad sectors. The drive features 3D NAND flash memory that helps maintain high data transfer speeds, making this drive a true speed demon. This drive is capable of delivering enhanced boot times along with a huge increase in overall system performance, a hallmark of most SSDs to be sure, but enhanced greatly by its advanced SLC Cache Technology. Along with the high data speeds are an increased lifespan, meaning you won't have to worry about the memory wearing down for many years.

The overall design of this drive makes it an ideal solution for ultrabooks, which often require extremely thin components. This drive certain fits the bill thanks to its thickness of just 7mm, making it possible to install in virtually any computer, especially ones with severe space constraints. Installation of this drive should be a breeze for anyone, thanks to its easy to follow instructions and the SP ToolBox Software, which will help you easily create backup copies of the older hard disk and copy over to the new drive. All in all, this highly rated SSD is a great upgrade for any computer thanks to its combination of high data transfer speeds and ease of installation.

Kingston A400

Fast and Affordable

The SSD from one of the most popular and recognised brands, the Kingston comes strong with one of its latest models - A400. Rigid, fast, and reliable - the A400 will not let you down.

In terms of specifications, the A400 model comes with a fairly fast (by today’s standards) read and write speed of 500MB and 450MB per second, respectively. The speeds will allow for a quick data transfer no matter how big are the files. Since things like video editing and online gaming require a lot of resources from your machine, this SSD will more than suffice your needs (better than any top-of-the-line hard drive, at the very least). And if you intend to use the SSD as a boot drive for your system, you will notice a significant increase in booting speed, which is also quite nice considering the modest price of this device.
Some users may find the read/write speed rates somewhat low. As the manufacturer states in the supplementary documentation, the main reason behind this is old drivers. Thus, it is recommended to update all of your firmware with newer versions of the drivers in order to achieve a minimum response time and the fastest speed from the SSD.
The 2.5-inch device is compatible with all modern SATA connection interfaces from SATA 1.5 Gb/s up to the SATA 6 Gb/s, which will be a neat thing to consider if you plan to upgrade your current system with that much-needed data transfer speed. The A400 SSD will be a good addition to any new system, an old computer, or a laptop as both an additional drive and as a replacement for soon-to-be-obsolete HDD drives. The only thing that may concern some users is the fact that this model comes without a SATA cable but it's not really a dealbreaker.
Review of Kingston A400 2.5 Inch SATA III Internal SSD

Not Much More You Could Ask For

Speed and interfaces aside, the model comes in four different flavours: 120Gb, 240Gb, 480Gb, and 960Gb. But we have decided to go with the 480Gb model as the most solid middle-ground solution out of the four.

Moving on, the Kingston A400 is resistant to shock and various vibrations, which will come in handy for those owners of laptops that tend to carry their gadget with them on a daily basis. The reliability of the SSDs cannot be underestimated, and Kingston beats almost every other brand in this aspect. If you'd like your data to be firmly secured, look no further - the A400 SSD is the right pick for you.

The Kingston A400 solid state drive is perhaps one of the best budget models available on the market today. It isn't perfect but you won’t be able to find a better deal for a 480Gb SSD with read/write speeds comparable to premium models.

Comparison of Solid State Drives

What Is a Solid State Drive?

If you want to buy a new computer or a laptop, you should take into account such individual components as the processor speed, RAM size, Wi-Fi availability and of course, memory capacity of the hard disk. This parameter shows how much information you can save on your computer. Nowadays, if you want to record or store information on the hard disk drive (HDD), you can face some drawbacks. That's why we would like you to pay some of your attention to the newish technology - a solid state drive. Solid state drive or SSD is a non-mechanical storage device based on memory chips. SSD is designed to replace the hard disk drives. The SSD is less energy-consuming and resistant to mechanical effects.

You still need to keep an external hard drive, for when we face a lack of storage space, SSD can't help a lot. Hard drives can help us store plenty of media content and not affect PC's performance. In addition, if you're looking for a comfortable keyboard to type, take a peek at our review on ergonomic keyboards.

What Features to Compare

For many people, the choice of an SSD drive is quite difficult. How to choose the best SSD correctly? What parameters of a solid state disk should you take into account? In this review, we will try to give answers to many questions related to the choice of the SSD drive.

First of all, you need to decide what Capacity of the SSD drive will satisfy your needs. Maybe, you would like to use this device as the main memory in the computer? As the additional one? Or just for the installation of the operating system? The standard capacity of a solid state disk varies from 60 to 500 Gb. As the practice shows, it is extremely convenient to use the SSD just as an operating system storage. It is better to store all other data like movies, music, etc. on the hard disk. If you think it will be a suitable option for you, the disc capacity from 60 to 250 Gb is surely enough.

SSDs can have different Form Factor. Nowadays, most of the solid state disks have a 2.5-inch form factor. This size is great because you can install the SSD on almost any laptop or PC. Several models have a smaller form factor, but it shouldn't be a problem at all. You can simply buy the adaptor.

Depending on the form factor, SSD drives can be connected to a PC or a laptop with the help of Connection Interface - PCIe or SATA (II or III). You should know that the data transfer rate of the SSD drive directly depends on the connection interface. If you are connecting the SSD solid via the SATA interface, it is better to connect it via the SATA III (up to 6Gb/s). You will see, the speed of the SSD drive will be much faster than with the SATA II (up to 3Gb/s). So, our suggestion - it is better to choose the drive with SATA III interface.

Also, you surely need to pay attention to such a feature as Read and Write Speed. The higher these figures are, the faster the work of the driver will be. However, you should notice that manufacturers indicate the highest possible speed characteristic. In reality, the drive probably will not work as fast (but still much faster than HDD).

In addition, you have to pay attention to the cycle index of re-recording. Nowadays, we can pick up two main types: MLC (Multi-Level Cell) up to 10 000 cycles and SLC (Single Level Cell) up to 100 000 cycles. All models in our SSD drive review are made on MLC technology. We would like to mention, that such type is the most acceptable in the quality-price relation. And don't forget about the warranty! The more, the better!

Did you know?

TBW, DWPD, MTTF—Which One Is the Most Important for an SSD?

Everything wears off after time, hardware does, too. For solid state drives, there are several parameters that showcase wearing and endurance. Same as with most products, the answer to the "Which one is more important?" question here depends on your needs and on how you plan to use the device. However, in our experience, the MTTF parameter is the one most often disregarded as irrelevant, both by customers and manufacturers. But still, let's define the terms before making a decision.

MTTF is the Meat Time To Failure of your drive. Basically, it's what it sounds like: the time before it stops working altogether. Do not confuse it with MTBF, Mean Time Between Failures. The latter is for devices that can be repaired and used again and again. Solid state drives are, as a whole, non-repairable. They don't have that many parts, to begin with, so when they fail, they fail for good. MTTF is expressed in hours it will take for the drive to fail under normal circumstances. Why is this parameter often overlooked? Because most drives have it in a number of hours equaling hundreds of years, longer than anyone uses them. This parameter is of importance for engineers working with critical systems, rarely for an average consumer.

TBW, or Terabytes Written, is the maximum amount of data you can write on the SSD before it fails. It is usually measured in hundreds of terabytes. It is not, per second, a capacity of your drive, which can be less than even 1 TB, let alone hundreds. The thing is, even when you delete data from the device, the amount of space it took up is still remembered in the core. So you write the data, then erase it and write something new. The capacity does not dwindle here, at least not much, but when, eventually, the TBW is exceeded, you won't be able to write more data even if there is actual space free there. The drive can still be read, though, most of the time.

DWPD, the Drive Writes Per Day. This is the parameter most directly connected to the warranty, capacity, and the TBW. It is, in a nutshell, the number of times you can re-write the drive in its full capacity every day for it to fail right on the day its warranty ends. For example, when the DWPD is 1, the warranty is 3 years, and the capacity is 1 TB, it means you can write and re-write 1 TB of data every day for the next 3 years, after which the drive will die on you. Usually, the DWPD is less than 1, it is calculated like this:

DWPD = TBW / (Warranty * 365 days * Capacity).

If you do not overwrite the drive completely (or in any significant part) every day, you may not worry about this.

Knowing all this, you can decide which parameter to turn to when you are buying a new solid state drive.
