The M.2 interface solid state drive has become the standard configuration of hard drive products for computer platform users due to its high-speed read and write performance and simpler installation characteristics that are much higher than that of the SATA interface. At the same time, the storage chip as the core of SSD capacity has improved in single-chip capacity and iterative upgrade of main control chip performance. Large-capacity M.2 interface SSD will become the choice of future public users.
At present, the mainstream large-capacity solid-state hard drives are mainly 512GB and 1TB. In particular, the 1TB capacity specification can well meet the current needs of most computer user groups. The 1TB capacity is not only used as a system disk on a PC desktop, it can easily take into account system installation and The installation and operation of the core large-scale software and the need for cache space have expanded the support for use as a mobile application platform for laptops that are mainly mobile applications and whose expansion space is strictly limited.
The competition for large-capacity solid-state hard disk products is gradually fierce. In addition to the traditional old-brand manufacturers that seize the opportunity and have the strength, many new solid-state hard disk brands have also stepped into this, thus forming a pattern of separatism and strength. In view of this, Lexar, as a storage brand that has been deeply involved in the storage industry, recently launched a second model of its M.2 interface professional solid state drive with Professional, and it is also a PCIe 4.0 protocol support. Flagship solid state drive—Lexar Professional NM800 M.2 2280 NVMe solid state drive.

Lexar NM800 Solid State Drive-Product Appreciation
The Lexar Professional NM800 solid state drive has two capacity versions, 512GB and 1TB. The version we obtained is a 1TB capacity version, which is also marked on the outer packaging, which can well distinguish between different capacity versions.
The NM800 solid-state drive adopts a single-sided PCB design. All storage components, main control chips and peripheral function control circuits on the solid-state drive are laid out on one side of the solid-state drive PCB substrate, and the side where the components are laid out is covered with a label with a thermal conductivity design. , The label is composed of three colors of black, gold and gray, marked with the product model name and core parameter specifications. At the same time, the composite material design of the nano-copper foil layer is used in the label material, which can enhance the heat dissipation performance and have a heat dissipation function similar to the heat conductive sheet, which can be described as one thing with multiple functions.
The back of the PCB substrate is also labeled with black and white colors. The content on the label is the product information barcode and related data parameter descriptions.
After lifting the label on the front of the solid state drive, you can see the specific layout of the components on the PCB substrate. There are roughly three areas: the main control chip circuit part in the interface area, the buffer circuit part in the middle and the storage at the tail. Chip part.
The NM800 solid-state drive is equipped with an InnoGrit IG5236 controller on the main control chip, which has 8 NAND channels and supports a capacity of up to 8TB. According to relevant information from InnoGrit, the IG5236 main control chip can provide sequential read performance of up to 7400MB/s and sequential write performance of up to 6.4GB/s. Cooperating with the high-bandwidth and low-latency data transmission support provided by the M.2 interface (NVMe protocol), it can lay a solid foundation for the performance of SSDs to bring better read and write efficiency
The cache circuit part is equipped with a DRAM cache chip with a capacity of 1GB, which provides data exchange cache when the solid state drive is working.
The memory chip part uses two memory chips with the model number NC66THA1884512G to form the 1TB capacity of the solid-state hard drive, and the soldering effect of the components around the chip is clean and tidy. At the same time, the soldering and layout of the components on the entire PCB substrate perform very well, as the brand's flagship level Positioning products also highlights Lexar's outstanding capabilities in product development, production and quality control.
Lexar NM800 solid state drive-performance test
The test platform used in this evaluation, the motherboard is ASUS ROG C8H WIFI, CPU is Ryzen 9 5900X, RAM is Trident Z Royal Elite, system disk is Samsung 970 EVO PLUS 1TB, data disk is Samsung 870 EVO 4TB, test The disk is Lexar Professional NM800.
First look at the actual available space of this hard drive, you can see that the available space displayed in the system reaches 953GB, which is in line with the capacity level of a 1TB hard drive.
Using the hard disk health detection tool CrystalDiskInfo to view the hard disk information, we see that the Lexar NM800 1TB firmware version is 126.96.36.199, the transmission mode is PCIe 4.0 x4, it supports the NVMe 1.4 standard, supports SMART, TRIM and VolatileWriteCache functions, and the standby temperature is 42 degrees.
Use CrystalDiskMark test software to test the solid-state hard disk empty disk. In the 1GB read and write test, the read speed of Seq Q8T1 was 7473 MB/s and the write speed was 5729 MB/s. In the 16GB read and write test, the read speed of Seq Q8T1 was 7476 MB/s and the write speed was 5715 MB/s, the overall data read and write performance is in line with the transmission protocol supported by the solid state drive and the performance strength of the hardware configuration.
After the CrystalDiskMark test, let's take a look at the performance of the NM800 in the AS SSD software. In the 1GB read and write test, the 4K multi-threaded read IOPS score was 353,489, and the write IOPS score was 897977; and in the 10GB read and write test Among them, the 4K multi-threaded read IOPS score was 356069, and the write IOPS score was 940026. The performance is also remarkable.
After reading the performance of the Lexar NM800 solid-state drive when the disk is empty, let's take a look at the performance of the Lexar NM800 solid-state drive when the storage data volume reaches half of the disk?
Also first use the CrystalDiskMark test software to perform a half-disk test on the solid state drive. In the 1GB read and write test, the read speed of Seq Q8T1 was 7472 MB/s and the write speed was 5730 MB/s. In the 16GB read and write test, the read speed of Seq Q8T1 was 7478 MB/s and the write speed was 5717 MB/s, so it can be seen that there is no big difference between the test data obtained when the empty disk and the test data obtained when the half-disk is At half-time, its performance can still maintain a high performance level similar to that of an empty disk.
In the TxBENCH SLC Cache cache test conducted with an empty disk, the Lexar NM800 1TB SLC Cache space is actually relatively large, reaching 316 GB, which can meet the daily entertainment and game use of most users, even if it is more than open programs. There is absolutely no problem.
During the SLC Cache test, we also monitored the surface temperature of the hard disk vest. It can be seen that the heat dissipation vest equipped with the Z590 snow blowing motherboard has a good temperature performance, with the highest temperature reaching 50.4 degrees. You must know that Lexar NM800 itself does not have a special metal heat sink, but a thermal conductive material is added to the label for heat conduction and heat dissipation. If you want a better heat dissipation effect, you can also add a metal heat sink to strengthen the SSD. The heat dissipation performance.
Lexar Professional NM800 M.2 2280 NVMe SSD is Lexar's second flagship SSD with Professional naming and adopts the latest PCIe4.0 protocol support, which compares to other PCIe3.0 protocols in terms of read and write performance The SSD has better performance. In fact, the performance of reading and writing data obtained by testing it can maintain a high level regardless of whether it is an empty disk or a half disk. However, the cache part may be its only shortcoming at present, especially The impact of big data on cache performance is still relatively large. I don't know whether the subsequent firmware update can improve this shortcoming through algorithm changes.
The 1TB capacity of the Lexar Professional NM800 M.2 2280 NVMe SSD can meet the current needs of both desktop and laptop user groups. The high-speed, low-latency and large-capacity hardware configuration is worthy of the recent upgrade of SSD users. .
