The next big leap in the world of micro-storage cards can be achieved thanks to the adoption of PCI-Express technology and the leader in the field SanDisk Volunteer to demonstrate this
Small external cards are a convenient and efficient solution to increase the amount of storage available on any computer product, and therefore continue to be a very common addition to both smartphones and personal computers today, many years after they were introduced for the first time.
The performance of these small, large-sized plastics has indeed improved over the years in several aspects, both in volume growth and in the relative price reduction storage Given - but all this still felt too little compared to the rapid progress of the built-in volumes.
The solution that could propel the performance of SD cards forward is beyond the limited standard on which they are currently based to the agile and sophisticated PCI-Express standard - and this is something that the company SanDisk (SanDisk) has chosen to advance by demonstrating the potential of a prototype it has developed alone.
A completely standard SD card in its dimensions was adapted for work in front of an M.2 connector and an artery PCI-Express A relatively modest 3.0 × 1 physical behind it, which will be enough for a card to display continuous read performance of over 850 megabytes per second, writing performance approaching 450 megabytes per second and also maximum random performance with small 4 kilobytes of over -100,000IOPS.
At the moment, this is only a demonstration that will not reach the stores due to being over-standard, but SanDisk believes that this will be an important boost in creating demand and demand for a suitable future standard - and indeed it seems that the SD Alliance responsible for this standard Which will be based on the current third-generation PCIe arteries, as well as subsequent editions that are already in the pipeline with the intention of doubling the possible bandwidth each time.
Believe that it will be the next big thing, at least for the computer world? Let's tell in comments.
