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.

    I suppose there are a few 5 pound laptops out there for power users that still use the 2.5" form factor, but they're disappearing rapidly. Things are moving fast in the SSD storage area and many are moving to the M.2 format. Though I suppose any increase in density is good as it means higher cap small format drives and cheaper options*.

    *so that Microsoft and Apple can increase their profit margins on storage. The great thing about impossible to open PCs is that they can charge whatever the fuck they want for storage no matter how cheap it gets.

    Is it just my observation, or are there way too many stupid people in the world?

    Then how is Apple having such good luck with them? Granted, Macs aren't generally used as high-transaction-count Servers; but people who do media creation/editing can sure churn through some R/W cycles in a hurry.

    First off, the problem is Linux is somehow triggering a bug in the TRIM implementation on Samsung SSDs.

    We know Windows doesn't do it, as Windows users are probably the biggest consumer of Samsung SSDs and there isn't a mass loss of data problem from Windows users. (And from querying Windows 7 via the command line, Windows does use TRIM).

    OS X may be using TRIM or not (depends on whether you're talking Apple-approved SSDs which are OEM versions, or third party user installed SSDs replacing the hard drive that was shipped). It's possible OS X may use TRIM in a way that it doesn't trigger the bug. Or maybe it does it less aggressively than Linux, so the bug incidence is far lower and no one noticed it yet.

    All we know is that Linux definitely triggers the TRIM bug, OS X and Windows doesn't, yet (but there are no guarantees that Apple or Microsoft won't change the way Windows 10 or El Capitan does TRIM which WILL expose the bug).

    The bug is in TRIM. That's all, if you don't use TRIM, it'll be fine. Maybe even using fstrim periodically is OK over using discard mode.
