Samsung Releases First 2TB Consumer SSD For Laptops

Lucas123 writes: Samsung has released what it is calling the world's first 2.5-in consumer-grade, multi-terabyte SSD, and it's issuing the new drive a 10-year warranty. With up to 2TB of capacity, the new 850 Pro and 850 EVO SSDs double the maximum capacity of their predecessors. As with the previous 840 Pro and EVO models, Samsung used its 3D V-NAND technology, which stacks 32 layers of NAND atop one another in a microscopic skyscraper. Additionally, the drives take advantage of multi-level cell (MLC) and triple-level cell (TLC) (2- and 3-bit per cell) technology for even greater density. The 850 Pro, Samsung said, can manage up to 550MBps sequential read and 520MBps sequential write rates and up to 100,000 random I/Os per second (IOPS). The 850 EVO SSD has slightly lower performance with 540MBps and 520MBps sequential read/write rates and up to 90,000 random IOPS. The SSDs will range in capacity from 120GB to 2TB and in price from $99 to $999.

Finally we have a reasonably sized SSD... now it's just got to come down in price 80-90%

Clearly you're not a gamer. 60 GB installs are the norm these days.

How does that work? Multiple Blurays?

Or video editor. Unless you are fastidious about getting rid of stuff, you can stack up some serious GB on each project.

I've got Civ 5 (5 GB) on my system, and Flight Simulator X (25 GB) , Simcity 4 (1 GB) , Simcity 5 (3 GB), several Railroad Tycoons, Age of Empires, Zoo Tycoons, GTA IV, several versions of Tropico, plus I have Tomcat, IIS and SQL Server, and a complete backup of my previous system (which has a previous backup of my previous previous system, ad infinitum). My whole system uses about 375 GB.

Good Summary

[Art3x]

This summary is well written. It is:

• Complete: It covers all of the main facts. There was no big question left in my mind after reading it. It's so complete that many will not go on to the article itself. (Not that they would anyway. This is Slashdot.) But that's what headlines and leads are supposed to do. They are supposed to tell the whole story, from beginning to end --- just not with every last detail. If you want all the last details, you read the rest of the article.
• Approachable: It defines all but the most common acroynms. For one it even goes further than just spelling out the acronym and also gives a nice little picture: ". . . 3D V-NAND technology, which stacks 32 layers of NAND atop one another in a microscopic skyscraper."
• Well-built: The English is good. Although technical, it uses plain English where it can instead of buzzwords. The sentences are not too long or tangled with several interdependent clauses. They have a good rhythm. You hear the words in your head even when reading silently, so sonic things still matter, like rhythm, alliteration, and rhyme (That doesn't mean you should rhyme all the time).

As a former professional technical writer, I am always on the look-out for good explanatory writing. I wanted to call it out here, especially since often we just complain when the summary's bad. When something's good, we're often silent. I suppose that's partly because when things are working, like the utility company, they don't attract attention and we just take them for granted. But writing like this is no accident.

Re:Warning: DO NOT USE SAMSUNG SSDs IN LINUX SERVE

[mlts]

Since TRIM is a standardized command, SSD vendors either need to support it, or like is done with the format command on IDE drives... do nothing, return a success value.

It is better to do nothing than to do it broken, and TRIM isn't exactly a new technology... it has been around for quite a few years now.

Re:encryption won't help you against malware

[billstewart]

Doesn't matter whether they use security-by-obscurity or real hardware-driven or OS-driven encryption. The malware's running on top of the OS, which already has access to all the data on the drive (unless you're doing something fancy with multiple user logins, each of whom has differently-encrypted home directories, but even then, the malware can attack whoever's logged in right now.)

Drive encryption mainly helps you against stolen hardware, and not usually very much, because that would require an inconvenient user interface.
