But still, you can go to Amazon and get something like this: https://amzn.com/B01IAGSD68 https://amzn.com/B01IAGSD68 at 22 cents/GB, 510/530 read/write speeds, 92K/83K random read/writes.

  The extra cost is for the enterprise features. For example the MX300 quotes endurance of 200-300TB. The 5100 is several times that - up to 17PB. If you're running a database server then you might need that endurance.

    Not sure i buy into that. Sounds a lot like sales talk. Be interesting to see how they compare with these guys: http://techreport.com/review/27436/the-ssd-endurance-experiment-two-freaking-petabytes http://techreport.com/review/27436/the-ssd-endurance-experim... and, afaik, for enterprise, sas hdd still leads ssd in performance price and endurance.

      Endurance of consumer SSDs may be derated for marketing reasons, but there are also physical differences that give enterprise SSDs higher endurance. A consumer 240 GB SSD has 256 GB of flash, while an enterprise 240 GB SSD may have 512 GB of flash. More flash allows more writes and the effect is nonlinear because FTLs are more efficient with more free space.

        I was commenting less "consumer v enterprise" and more "consumer vs consumer that pretends they are enterprise". Enterprise servers are mostly sas interfaces. These are sata, which is mostly home and soho plus a few startups running on a shoe string (afaik)

        A SATA SSD with capacitors, high endurance, and a good warranty is not "consumer that pretends they are enterprise". It's actually better. Really the only advantage of SAS is dual port and some customers don't need that.

        The benefit of 15k SAS drives is 250MBs per drive actual throughput, even more because they are RAID arrays - for 3c a GB, they are HIGHER performance than most SSD drives on the market. Sticking "enterprise" on the box will not make enterprise pay 42c per gig for less performance.

        In general enterprise SSDs are not using SAS, they are either NVME or SATA. For example, intel's datacenter range https://www-ssl.intel.com/content/www/au/en/solid-state-drives/data-center-family.html https://www-ssl.intel.com/content/www/au/en/solid-state-driv... has no SAS drives.

        in gerneral enterprise is not using ssds. so you kinda missed the point. and when the hardware they plug into is a sas interface, they arent going to be buying them either. seriously, getting a bit tired of the immaturity and shilly nonsense on here. check any rack machine from cisco, dell or any of the other big enterprise suppliers (of which intel is an oem, they dont really deal with the likes of hsbc or shell corporation) and they all come with sas interface for storage. enterprise means "more than 10000 employees". you do have dedicated support personel from your supplier. intels "data center range" definately isnt enterprise imho. enterprises still not stupid enough to go anywhere near the cloud.

  "Dynamic Write acceleration" means its TLC nand emulating SLC nand. At some point your write saturates the buffer and you lose the speed advantage. The MX series have a dynamically expanding buffer (unlike samsung evos and other competition which have a static sized buffer,) but its not infinite.

  The sustained random write speed of that drive is more like 6600 IOPS, even though its burst performance in ideal conditions is close to what's specified.
