Verizon’s Samsung Galaxy S20 has mmWave 5G but less RAM

  Verizon’s Samsung Galaxy S20 has mmWave 5G but less RAM There are some compromises for this 5G smartphoneAs spotted by Digital Trends, the Galaxy S20 5G UW has 8GB of RAM, which is 4GB less than the standard Galaxy S20. The Verizon model also does not include a microSD card slot, which allows owners to expand the phone’s storage capacity. “We had to make certain design and hardware decisions to provide a device with the form factor and price point as other S20 models,” a Samsung spokesperson told Digital Trends. The Galaxy S20 5G UW costs $999.99, the same price as the Galaxy S20.

Samsung finally has an 8TB solid-state drive that’s ready for the mainstream. The company has unveiled an 870 QVO range of SSDs that ranges from ‘just’ 1TB through to the flagship 8TB capacity — enough that you may not have to worry about free space for a long time. It’s an SATA drive limited to peak sequential read and write speeds of 560MB/s and 530MB/s respectively, but Samsung is promising a 13 percent boost in random read speeds over the 860 QVO.

And before you ask: it should last a long time before losing its write ability despite the quad-level cell flash memory. The 8TB model is rated for an endurance rating of up to 2,880 terabytes written. You’d have to completely rewrite the drive 360 times before running into trouble, to put it another way. That 360-times endurance applies to lower-capacity models as well.

Samsung's PCIe 4.0 SSDs come in a range of new form factors

  Samsung's PCIe 4.0 SSDs come in a range of new form factors Intel’s “ruler” form factor for NVMe server SSDs once looked radical, but it’s now become mainstream. As evidence, Samsung just introduced a new line of ultra-fast PCIe Gen 4 drives derived from Intel’s original design. The PM9A3 SSDs come not only in the standard M.2 NVMe format, but also in the newfangled E1.S format (a shorter version of Intel’s ruler) and U.2 — which looks like a SATA drive but is much, much faster. The E1.S and U.2 variantsThe E1.S and U.2 variants of these drives (designed for data centers, not consumers) can hit up to 6,500 MB/s read and 3,500 MB/s write speeds and capable of 900,000 IOPS (random reads). These speeds are double what PCIe 3.0 drives can handle because PCIe 4.0 has double the bandwidth. The M.

You’ll have to keep waiting for pricing. The 1TB, 2TB and 4TB models are available today at respective prices of $130, $250 and $500, but the 8TB version doesn’t arrive until August and doesn’t yet have a price. The pricing model suggests it may cost closer to $1,000. That wouldn’t be outlandish for what you’re getting, although it’s definitely not a trivial purchase.

There’s one main issue: the competition isn’t standing still. Sabrent recently introduced an 8TB SSD of its own, and that’s a PCIe drive with much faster transfer speeds. It costs a hefty $1,500, but the premium might not be that much of a deterrent if you can justify an 8TB SSD in the first place. Samsung’s offering is more for that subset of enthusiasts (and certain pros) who can afford a capacious drive but still need to keep their costs vaguely in check.

Arm helps chip allies like Qualcomm push speeds higher with its X1 processor customization plan.On Tuesday, Arm unveiled its new Cortex-A78 processor design, which should provide a 20% speed boost compared with Arm's current A77, said Paul Williamson, general manager of the product line. Chips based on the more customized Cortex-X1-based designs get another boost of up to 22% more than regular A78 designs.
