Samsung announces the largest SATA SSD: 4TB 850 EVO

Magnetic storage, watch out.

Maybe you can ditch that hard drive after all. Samsung said Monday morning its new 4TB 850 EVO now stands as the world’s highest-capacity consumer SSD.

The drive offers double the capacity of the previous 850 EVO and will reach sequential read and write speeds of 540MBps and 520MBps, respectively—pretty much the max of the SATA interface.

SATA, of course, is the key word here. Samsung has been shipping a near 16TB drive (which you can read about here) for months already, but that drive runs on the server- and workstation-focused SAS interface. The 850 EVO's SATA interface and 2.5-inch form factor make it an ideal solution for consumer desktops.

Samsung has also had a 3.84TB SATA SSD available since last year, but it's built for datacenter use, supports far more writes than consumer drives, and costs more. With the new 4TB 850 EVO, Samsung uses its well-respected V-NAND and rates it for 300 terabytes written.

In performance, the 850 EVO can’t touch drives running on the M.2, U.2, or PCIe interfaces, but for capacity it can’t be beat today.

Naturally, you want to know the price. Samsung said the list price of the 4TB 850 EVO will be $1,500 with a five-year warranty. For comparison, the current 2TB 850 EVO sells for $675 on Amazon, so that price seems in-line.

Why this matters: Everyone is waiting for the day when they no longer need hard drives for bulk storage, and with SSD capacities creeping ever higher, this is another possible nail in the coffin of magnetic media.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
