Toshiba introduces new nvme-ssds design with memory card size
Many electronic products use soldered BGA solid-state drives based on internal design and size, but users who want to replace the hard disk themselves will be very difficult. At the same time, based on the speed considerations, more and more users choose NVMe type solid-state hard disks, and this type of hard disk cannot be used for soldering disk devices. The good news is that Toshiba Storage now offers NVMe SSDs like BGA variants, which are so small that they can be used to replace soldered hard drives.
Users of M.2 NVMe SSDs should know that these drives are very small. Toshiba’s new XFMEXPRESS SSD supports dual-channel or quad-channel PCIe, which is no difference in speed from ordinary M.2 SSDs. From the picture, Toshiba’s new SSD is very similar to the microSD card, but it is actually bigger and thicker than the microSD card.
Since the size is very small and supports the use of a dedicated connector, can the XFMEXPRESS SSD be called as an external storage device? The answer is no, although the above assumptions are theoretically achievable, Toshiba has indicated that it is not prepared to use this type of solid-state drive as pluggable storage. This means that it is still built into the device instead of adding a slot as an accessory to the user. It is not clear why Toshiba did this.
In addition, because the size is relatively small, heat dissipation is also a relatively big problem. Toshiba claims that the heat dissipation mainly depends on the metal casing of the hard disk external connector. At present, Toshiba has cooperated with Japan Aviation Electronics Industry, Ltd. to develop such connectors to ensure that XFMEXPRESS heat dissipation will not be a problem.
