Two years ago, Samsung unveiled a massive 15.36TB SSD and now it has doubled that storage in a single drive the PM1643. To do that Samsung used its V-NAND technology and 64-layer 3-bit 512-gigabit (Gb) chips. Samsung's PM1643 SSD is the successor to 15.36TB series, introduced by the company in March 2016. To achieve such performance numbers, Samsung used Through Silicon Via tech the drive includes 40GB of DRAM. Now this year, Samsung is taking it a step further with the new "PM1643", a 30TB SSD built on the latest 512Gb V-NAND. The drive has a 12GBps SAS interface with random read and write speeds of up to 400,000 IOPS (Input/output operations per second) and 50,000 IOPS as well as sequential read and write speeds of up to 2,100MBps and 1,700MBps, respectively. It also offers impressive sequential read and write speeds of up to 2,100MBps and 1,700MBps respectively. This is three times faster than a normal SATA SSD. Jaesoo Han, executive vice president of Samsung's Memory Sales and Marketing Team commented that, "Samsung will continue to move aggressively in meeting the shifting demand toward SSDs over 10TB", which is good news for everyone. The advanced controller integrates nine controllers from previous high-capacity SSDs into a single package. The PM1643 also applies TSV technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages. This is the first time that an SSD has included a TSV-applied DRAM.
Facebook for iOS Now Offers a VPN Client Under 'Protect' Option
Such data is attractive information for Facebook , hence why it bought the Israeli security company behind Onavo Protect in 2013. And many users likely wouldn't realize that other VPNs approach privacy differently, and offer much more extensive protections.

The outage comes amid an uproar over a redesigned iOS app, which has users looking for ways to install the previous version . But now Snapchat is facing criticism that the app reorganization makes it harder to navigate.
Manchester City vs Leicester City
It is not yet known if his decision to report for training puts him in contention to feature for the first time since 20 January. Riyad Mahrez returned to Leicester City's training ground today for the first time in 11 days, ending his self-imposed exile.
The PM1643 also features enhanced software that supports metadata protection, data retention and recovery from sudden power failures as well as an error correction code (ECC) algorithm for high reliability and minimal storage maintenance. Moreover, there is a mean time between failures (MTBF) functionality for up to two million hours. The device is quite robust too, with an endurance level of one full drive write per day. This should help drive the growth of all-flash arrays and migration from HDDs to SSDs in the enterprise market, including industries such as government, financial services, education, healthcare, pharmaceutical, oil and gas, business services, communications services, and of course the ever-important social media platforms.
