Samsung has launched a new SSD that is smaller than a postage stamp, and is said to be the world’s fastest but smallest 512GB SSD and also the world’s smallest NVMe SSD.

The latest PM971-NVMe SSD offers storage capacity up to 512GB, and comes with extremely fast read and write speeds.

Designed for the next generation of super-thin ultrabooks and notebooks, the PM971-NVMe comes in at 20mm x 16mm x 1.5mm, and weighs a gram.

“It will also ‘triple the performance of a typical SATA SSD,’ Jung-bae Lee, Samsung’s senior vice president of memory product planning & application engineering team,” said in a statement.

It is wrapped in a single BGA package by merging 16 of Samsung’s 48-layer 256GB V-NAND flash chips, one 20-nanometer 4GB LPDDR4 mobile DRAM chip, and an in-house controller.

Samsung claims that the PM971-NVMe SSD offers read and write speeds of up to 1500MB/s and 900MB/s respectively. These figures will allow a 5GB full-HD movie to be transferred in just three seconds, and downloaded in 6 seconds.

Furthermore, Samsung claims that it supports random read and write IOPS (input output operations per second) of up to 190K and 150K respectively.

When compared to a traditional hard drive, the company claims that the new PM971-NVMe SSD is 1,500 times faster.

Samsung says it will manufacture the SSD in 128GB, 256GB, and 512GB capacities, and make them available to its customers next month.

Sleeping in on weekends may help live longer

Sleep deprivation has been found to have numerous negative effects on a person’s health. But the new study has shown that sleeping more on the weekend might help ease health problems associated with not getting enough during the week, and even reduce the risk of an early death.

The study, published in Journal of Sleep Research by scientists from Sweden and the United States, suggested that the negative effects of a few nights of short sleep could be counteracted by staying in bed over the weekend.

The from the Stress Research Institute (SRI) at Stockholm University and the Karolinska Institute discovered that people below 65 years old who slept less than five hours on weekends had a higher risk of early death after examining medical and lifestyle data from more than 43,000 adults, following them for a period of 13 years.

For people who slept for less than five hours throughout the week but slept longer on the weekends for about nine hours, there was no increase in mortality risk. But, for people who consistently slept for less than five hours through the whole week, the mortality risk is higher.

Torbjorn Akerstedt, one of the authors of the research and a clinical neuroscience professor from the Karolinska Institute in Sweden, said that the findings were consistent with previous studies on the link between sleep duration and mortality.

However, those previous studies only focused on sleep during weekdays.

“The results imply that short sleep is not a risk factor for mortality if it is combined with a medium or long weekend sleep,” the researchers wrote in the study.
