Samsung Demos PCIe NVMe SSD At 5.6 GB Per Second, 1 Million IOPS (hothardware.com)

MojoKid writes: Samsung decided to show off their latest SSD wares at Dell World 2015 with two storage products that are sure to impress data center folks. Up and running on display, Samsung showcased their PM1725 drive, which is a half-height, half-length (HHHL) NVMe SSD that will be one of the fastest on the market when it ships later this year. It sports transfer speeds of 5500MB/sec for sequential reads and 1800MB/s for writes. Samsung had the drive running in a server with Iometer fired up and pushing in excess of 5.6GB/sec. The PM1725 also is rated for random reads up to 1,000,000 IOPS and random writes of 120,000 IOPS. The top of the line 6.4TB SSD is rated to handle 32TB of writes per day with a 5-year warranty.

Rating vs. Warranty

[Anonymous Coward]

Samsung PRO line offers 5 years or total bytes written, whichever comes first, as a part of their warranty package:

While this drive "is rated to handle 32TB of writes, every day for five years without failure" - I want to see a warranty to go with that. That's ~58400TB total, about 200 times higher than their best warranty offers right now at 300TBW.

Given the endurance test people have peformed against "consumer" SSDs, it sure seems like the expected endurance exceeds the warrant by a lot.

This guy:

http://blog.innovaengineering.... ...has 7 PB written to an 850 Pro and it's still going (last blog update was more than a month ago).

I'd be awful curious to see what the actual durability of an 850 Pro would be in a real production SAN. My suspicion is that the better-than-rated endurance coupled with the low replacement cost might make it worthwhile when you consider the staggering performance you would get.

There might even be gimmicks you could apply on a per-disk basis to improve durability, such as underprovisioning each drive by 25% so that you could wear level across more capacity.

You don't need an explicit warranty anywhere with sensible consumer protection laws. The Sale of Goods Act in the UK (and equivalents in most EU countries) allow you to return the goods for a full refund if they do not meet the promises made at time of sale. I had a battery fail in an Apple laptop after four and a half years, but within the number of charge cycles that their ads claimed. They replaced it (couriered out a replacement that arrived at 9am the day after I called them at 3pm - better service than I've ever had from them for anything under warranty) as soon as I mentioned the Sale of Goods Act.
