It's not about the devices that use the Thunderbolt 3 interface. However, this does not mean that this interface is not crowded. Additionally, we can say that today Thunderbolt 3 is a standard option for laptops. The interface can be found in modern laptops of the leading manufacturers, especially in the category of top-price models. However, the problem with clearing the connected devices through this interface is not clear. At this time, there are not so many compatible gadgets, and most devices are external video cards or storage channels or connectors to monitor.

Samsung, the South Korean company, decided to enter this market. The Thunderbolt 3 features a very good definition of the NVMe interface to connect to solid-unit connections. The Samsung Portable SSD X5 external drive, discussed in this review, acts as the director of this idea in life. Samsung Portable SSD T5 SSD has recently been reviewed with a portable 850 EVO SATA drive. The portable SS5 X5 is also a portable external SSD model, but everything is different. Instead of the USB interface, Thunderbolt 3 is used and SATA is not used internally, but the NVMe drive.

As a result, Samsung did not create a fast and fast external SSD. Unlike Thunderbolt 3-unit manufacturers, based on Samsung's Phison PCIe 3.0 x2-bridge, Samsung did not save and only selected advanced components for its solution. These are Intel's Thunderbolt 3-bridge Alpine Ridge and high-end SSD, like 970 EVO.

As Samsung Portable SSD X5 tells us, it is the best solution. However, there is a negative side; As a result, the product is not cheap. For the X5 version of 500 GB, 28,990 rubles have been requested, a terabyte disk is required, 49,990 rubles are payable, and the old version X5 has a capacity of 2 TB, 99,990 rubles. An external SSD may be more in case of compassion for paying money.

⇡ # External performance and features

Surprisingly, Samsung does not complete a single style in its external drive design. The new X5 is completely different from T5 and T3 earlier. The company's sharpening designers sooner do, the portable X5 XDS looks much more auspicious and sleek, with a cigar-shaped profile. With external support, Samsung suggests a race car.

In addition, the new Thunderbolt 3 interface is larger and heavier than the predecessor: more than 150 grams weighs 116 x 60 x 18 mm in dimensions. In Samsung T5's review, we could not use "miniature" epithets, but we're not going to let it go so far: X5 is lightweight but lightweight.

As Samsung explains, choosing the sizes and materials to make the case is a mere reflection. After all, the body not only addresses the problem of attracting product attention, but also fixes other tasks: protecting the padding and removing heat from the heat. Therefore, it is not surprising that construction uses an unusual material. Half of the body has a different look, but the lower half, painted "glazed asphalt" with glossy paint and the top, with a red color, is made with the same metal.

And this is not traditional aluminum, but lighter, but more durable magnesium. As a result, the manufacturer can withstand Samsung Portable SSD X5 body from a 2-meter high. But do not dispose of water – it does not provide moisture protection.

At the end of the device, there is only one connector: the USB C key, with the Thunderbolt 3 internal interface. Data transfer and device provision are made through a single cable. Next to the USB port type in the case, there is a white LED that indicates the activity of the disk. The Thunderbolt cable has a length of 45 cm with the disc, but there is no X5 accessory, that is, devices with this cost have no features.

The interfaces used to connect the external units have made a significant difference in recent years. The first external Samsung SSD, T1, was connected via USB 3.0 and could offer hundreds of megabytes per second. The next series product, Samsung T3, went to a Type-C connector that was USB 3.1 Gen 1, but this did not improve at a speed. But the T5 model created linear velocities around 540 MB / s. The next version of the secret interface was presented – USB 3.1 Gen 2 10Gb / s broadband theoretical.

The Thunderbolt transition has not been surprising since it happened in the new Samsung external drive. The first version of the interface is also used as USB 3.1 Gen 2 as 10 Gb / s. And the modern version of Thunderbolt 3 is four times faster. Its capacity reaches 40 Gb / s, which is enough for a faster consumption level SSD. Samsung reads and writes the sequences of the new X5 sequences between 2.8 and 2.3 GB, respectively. That is, at least 5 times faster than a portable SSD on the T5.

Note that although the most common type-C connector is used, the Thunderbolt 3 port is not compatible with the USB back. That is, you can connect Samsung Portable SSD X5 and computers are waiting for Thunderbolt 3 interface to wait for orders. Additionally, the computer must have a relatively cool operating system: Mac OS X 10.12 or later or Windows 10 version 1703 and above.

In general, the specifications considered portable SSD are as follows.

The great advantage of Samsung X5 supports AES256 data encryption without imposing a penalty for performance. The encryption is managed through the Samsung DATA SSD portable.

It should be noted that the proprietary utility has a very reduced functionality: only enable encryption – and nothing more. Therefore, all the information about the diagnosis will not work. But for this it is possible to use third-party programs, such as CrystalDiskInfo.

Note that we are talking about an external device, CrystalDiskInfo uses NVM Express 1.3 as a protocol. The use of the standard component within the X5 is a precise recovery: a Samsung 970 EVO drive based on the Samsung TDC NAND drive.

Nonetheless, there is still no limit on abilities. For example, from CrystalDiskInfo's testimonial X5 does not support TRIM, although the Thunderbolt 3 interface, which is a PCI Express bus structure, should be completely transparent. It's all a file system. The unit is formatted when formatting exFAT and if NTFS is formatted, TRIM support will appear.

But here it should be taken into account that this recipe is suitable for computers that only work on the Windows operating system. External formats with NTFS are recognized as Mac OS X readers.

⇡ # Internal device

To create portable SSD drives, the same scheme is used: the extra bridge is added to some traditional series series, compatible with the external interface.

This is exactly how Samsung Portable SSD X5 is done. The base of this SSD is the latest version of Samsung NVMe NVID-970 EVO (PM981) and has changed with the firmware. This means that Samsung X5 uses the TLC 3D V-NAND 64 layers, which is the newest eight-channel controller, controlled by Samsung Phoenix. In other words, there is a real M2 drive inside X5, which is installed on the slot, which is not in the normal device's device.

However, to combine the NVMe drive with the Thunderbolt 3 interface, another chip is installed on a X5 motherboard: the Intel Alpine Ridge Bridge. Thanks to this bridge, the 970 EVO speed is cut using the PCI Express 3.0 interface and internal NVMe SSD offers 40Gbps Thunderbolt 3 bandwidth access. However, the appearance of an additional node of Alpine Ridge data is still small due to the performance damage and the formal features of Samsung X5 a bit slower compared to the original 970 EVO. But this damage is not very high: it adapts to 10-15%.

The popular Samsung X5 desktop products are characterized by: first, the SLC-caching Intellegent TurboWrite in two phases. The essence of this fast-typing technology consists of the SLC-cache of the unit, which is both static and dynamic. As a result, Samsung Portable SSD X5 is capable of receiving high-speed information, which is even more important than an external drive.

We tested Samsung X5 with 1 TB of volume, and the total capacity of the SLC cache was about 36 GB. This would be enough for average usage situations, but it should be taken into account that the free space of the SLC cache has run out, the writing performance is about half: from 2.3 to 1.0 GB. This is illustrated in the graphic that is copied to the large SSD file.

If we explain how Samsung X5 was designed in a mechanical design, then it has to be emphasized that there has been a lot more cooling. This is natural: NVMe SSD high-speed dissolution is quite harmful, so all X5 internal heating chips are in contact with thermal contact, metal case or X5 metal mass distribution.

Straters do not have a positive effect on the thermal regime, but Samsung X5 cases will always have a comfortable temperature and will not create thermal combustion.

However, in the active work process, Samsung X5 allows the body to heat up to 40-45 degrees. But the temperature is not rising. This continues with another proprietary technology – Dynamic thermal guards, when the frequency of the Phoenix control inhibits more than 55 degrees. Of course, at the same time, it reduces the productivity, but as the usual thermal regime returns to its original state.

In other words, you should not fear Samsung X5. The unit increases the temperature and controls its state.

It seems strange for some reasons, the endorsements by Samsung for portable SSDs for X5 and three years. The internal unit 970 EVO has been granted a five-year warranty at the same time. Actually, a portable external SSD does not have a maximum limit on the charge. It seems that Samsung could use more than one SSD in real life.
