New Samsung SSDs can 'never die' thanks to 'fail-in-place' technology

What you need to know

  • Samsung announced two news SSDs that 'never die,' the PM1733 and PM1735.
  • The fail-in-place technology means that a single NAND chip failing doesn't ruin the entire SSD.
  • The new PM1735 can hit 8GB/s read speeds and 3.8GB/s write speeds.

Samsung announced two new PCIe Gen4-based SSDs, the PM1733, and PM1735. These new SSDs are incredibly fast, and take advantage of three new innovations, including fail-in-place (FIP) technology that ensures an SDD can "never die." While the drive technically can die, Samsung has mad it much less likely than it is for other SSDs.

Samsung began mass production of the two new chips last month. Samsung outlines the specs and innovations utilized in the chips in a news post (opens in new tab) (via PC World).

The PM1733 has a 6,400MB/s read speed, and 3,800/s write speed. The PM1735 has a read speed of 8,000MB/s and a write speed of 3,800MB/s. Samsung points out that the PM1735 offers almost 14 times the sequential performance of a SATA-based SSD. The PM1733 is available in up to 30.72TB, and the PM1735 is available in up to 12.8TB, though maximum sizes depend on the form factor you choose.

One unique feature about these SSDs is that they utilize Samsung's FIP technology. FIP software detects a faulty chip, scans for damage in data, and then relocates the data onto a working chip. On other SSDs, failure of just one NAND chip makes the entire SSD fail. FIP makes SSDs much more difficult to kill because a single failure doesn't spell the end of the drive. As an example given by Samsung is that a 30.72TB SSD from Samsung has 512 NAND chips. A large number of chips would have to fail before you'd run into issues thanks to FIP.

Additionally, Samsung highlights the role of SSD virtualization technology that allows a single SSD to be subdivided into up to 64 smaller SSDs. This allows multiple users to have virtual workspaces on a drive.

Finally, Samsung highlights V-NAND machine learning technology that helps accurately predict and verify cell characteristics. It also detects variation among circuit patterns using big data analytics.

  • That's pretty cool
  • That would especially be useful for laptop ssd's that ship with crappy unreliable ssd's lol (probably will take some time before those will. be improved).
  • This would be handy for "crucial" data - pun totally intended - have had only Crucial SSDs fail on me. Then again I only have every bought Samsung SSDs and took a chance on a Crucial SSDs because they were cheap. Goes to show why they were cheap... they don't last as long lol.
  • I'm waiting for a 980 Pro to be announced with PCI gen 4
  • I would only trust that claim if they also provided a lifetime warranty with the drives, put your money where your mouth is.
  • But it's not like the chips can't fail, it would still cost them money to refurbish them for you. Never die would hopefully mean you never lose data. Maybe they could give a guarantee of repairablity of the drive.
  • Ummm, these are "Enterprise SSD's" in U.2 and HHHL (Card Type) form factors and are priced accordingly.
    They are intended for large data centers and are not consumer tech.
    In a year or so we may see this tech trickle down to consumer drives, but not before that.
  • That was actually stated in the press release. It said they hope to get it in their other consumer options in the future. I'm sure it will trickle down.
