The solid state drive era began with 2.5 '' drives that communicated with the motherboard via SATA. After a while, they switched to the M.2 format, because the same drives are easier, more compact and cheaper than analogs of the notebook form factor. Almost immediately they ran into the ceiling of SATA and switched to PCI Express, since it was “embedded” in M.2. At the moment, there are plenty of different NVMe SSDs, but not everyone can boast a low price - controllers and 3D memory cost a lot of money. However, with due diligence, you can get into the budget sector, and keep the speed characteristics at the level. An example of this is the Transcend TS512GMTE110S.

Packaging, design features
SSD comes in a box of thin cardboard. The plastic blister protects from mechanical damage.
The drive itself is made in the format of 2280, the radiator is not attached.
Design featuresCircuits on the PCB are located on both sides.
The label with the label is glued to the controller chip, which forces it to be removed before installing the radiator
The controller is SM2263XT manufactured by Silicon Motion.
Introduced at the end of 2017, supports NVMe version 1.3, interface - PCI Express 3.0, 4 lines. Inside there are two ARM cores, it is possible to use DDR3 and DDR4 memory as a buffer. The XT modification (installed on the tested SSD) dispenses with its own buffer, using RAM instead of it (HMB technology). There is only one obvious advantage of such a solution - cheaper production and, consequently, the final price of the product. Peak data transfer rates are 2400 for reading and 1700 MB / s for writing. It can be seen that the controller was created for the production of low-cost models (by the standards of NVMe drives).
512 gigabyte NAND memory is equipped with eight THGMU3B-1D04 chips, 477 gigabytes available to the user.
Transcend claims lower read / write speeds than the controller manufacturer - 1700 and 1500 MB / s, respectively. Perhaps this is due to the memory used and some modifications of the firmware relative to the "standard".
Test resultsCrystalDiskMark, as usual, shows very close to the declared results of streaming reading and writing. The test utility AS SSD produces close to real speeds - from 780 to 1330 MB / s. The speed of operations with random four-kilobyte blocks is low - up to 30 MB / s.
The graphs of sequential read and write from the AIDA test package show that the drive copes with read operations, but a small amount of pseudo-SLC buffer spoils the big picture.
This fact does not give a reason to call SSD slow, but in general, the performance is slightly lower than that of other models on the same controller. Well, almost the same - with a gigabyte of allocated buffer. This is reflected not only in the results, but also in the price. It is higher on average by 10% with a slightly smaller volume.
However, a blind test in real problems is unlikely to reveal the difference between them, especially if you use SSD as a system drive.
An important moment when working more or less high-speed models (to which the TS512GMTE110S refers) is the heating of the controller. Two measurements - with and without a simple aluminum radiator-plate - show the importance of using a heat sink.
With active read-write operations, the controller warms up to 60 degrees, and this is on an open bench with good airflow from the processor cooler. The maximum operating temperature of the controller is 70 degrees, and it is quite possible to achieve it when installing an SSD next to a video card or power converter.
SoftwareYou can monitor the status of the drive with the proprietary utility SSD Scope. In addition to indicating the “health” parameters (disk full, cell resource, SMART information), there is a quick speed test, the option to transfer the system partition from HDD to SSD and the ability to update firmware.
Transcend has a second utility for recovering accidentally deleted information from different drives - RecoveRx. Easy to use and intuitive software.
Transcend TS512GMTE110S from all sides is good for a system drive with a cash deficit - it can be found for less than 7000 rubles. It is not as fast and cold as it would be if you used your own buffer and heatsink, but the first drawback is difficult to notice without tests, and the second is fixed for a hundred rubles. The rest of the SSD is similar to other NVMe drives of the 2280 form factor: compact, fast.prosMay not like
