We offer to purchase a Sandisk M.2 80mm (2280) format SSD drive with a 8 TB capacity.
This SSD drive has a compact and modern M.2 connector.
This SSD drive uses the latest NVME standard with PCIe interface, which allows simultaneous data transmission across multiple data lines. Thanks to this technology, the drive is ideally suited for those who work with large files, play computer games or deal with video editing.
7200 MB/s – this is the data reading speed that this SSD disk is capable of reaching. However, we must remember one crucial nuance - "fast" disks may not show the performance promised by the manufacturer if adequate cooling is not provided.
The writing speed for this SSD disk reaches 6600 MB/s. Without a suitable cooling mechanism, "fast" disks may not be able to achieve the performance indicators promised by the manufacturer.
To ensure memory chips maintain a low temperature and assure constant performance over long periods of use, the disk equipment is equipped with a cooler or a radiator. However, even if you purchase a "fast" SSD without a built-in radiator, it's not critical - almost all motherboards (99%) already have an integrated M.2 slot cooler.
This is an SSD disk in the M.2 80mm (2280) format.
This SSD drive interface is PCIe 4.0 x4. If you insert this drive into an older interface slot, the speed of the drive will decrease, as the drive will not have sufficient data transfer speed (Bandwidth).
Sequential read speed or the mean data reading speed is the most important criterion of the high-speed operation of the SSD. The data from the SSD will be read much more often than written to it because the operating system stores the processed data in the RAM in most cases.
If you want the reading speed of the purchased SSD to exceed the speed of the classic HDD considerably you should choose the SSD with the reading speed of 200 MB/s or above. The additional increase in the performance will be achieved on the account of the data search (SeekTime) which is of much higher level with SSDs than any HDD.
The writing speed is almost as important as the reading speed. Also this parameter determines the performance of the SSD, however, as the writing to the disc happens not as often as the data reading and average user will find it subjectively difficult to distinguish between any speed above 100 MB/s and higher indices, except the cases when the SSD is used in a server, for audio/video recording, etc.
Thanks to the small size provided by the SSD technology the standard size of the discs is 2.5", and it is suitable for an average portable computer. It is possible to install the 2.5" disc in the desktop computer if the transition 2.5" -> 3.5" is used, and this transition can be bought at a low cost at TopPC.fi section"Adapteri". The discs with the format 2.5" + 3.5" have this transition included.
1.8" discs are intended for the ultra-compact class portable computers.
PCI-Express SSDs are intended for desktop computers with a free PCI-Express plug available. This technology in most cases is used for ensuring the performance that exceeds the possibilities of other types of connections.
SSDs with SATAII and SATAIII connection are compatible with the connections of both types in the motherboard. Still, it has to be taken into account that the motherboard SATAII connection can provide maximum about 300 MB/s transmission capacity which can reduce the actual transmission capacity of the SSDs whose reading and/or writing speed exceeds this level to the capacity limits of the SATAII.
The situation is similar with the PCI-Express and SATAIII connection slots. Although the SATAIII standard can provide up to 600 MB/s data transmission capacity there are SSDs with the speed exceeding this limit, in this case the manufacturer chooses the PCI-Express connection slot with a higher transmission capacity. The PCI-Express discs cannot be connected to the portable computer.
