AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.

Incompressible Sequential Write Performance - AS-SSD

As a 3Gbps drive the 710 is pretty much limited by the SATA interface for the sequential read test. Sequential write speed is definitely improved over the X25-E, which may help narrow the performance gap in some enterprise workloads. Let's get to the real tests shall we?

    Use a CD; that's mechanical storage.

    Flash is definitely a poor choice, since charge is slowly lost. I'm not sure about magnetic hard drives.

    If you use optical media, better have it a manufactured ROM disk, as opposed to writable media.
    Even the best consumer optical media is only good for around 10 years.

    One thing intel and the rest of the SSD crowd by far have failed to address is the limitations of SATA for enterprise workloads. Doesn't matter how fast your drive is, on a SATA interface it will tank in truly heavy mixed I/O environments. Native SAS SSD's are needed to move the hdd form factor SSD's forward in the industry.

    That being said, in my research for an in-house project, I discovered Smart Modular. Their Optimus SAS SSD's are up to 1.6TB/drive, and at that capacity are still below $3/GB.

    To be fair, I have not gotten any of them in house to test yet, so I can't say how well they will do. But knowing the difference moving from SATA to SAS drives make in an array, I would have to imagine it will be significant when I do.

    Not to mention, from a pure density standpoint, 1.6TB 2.5" SSDs can pack more density per rack unit than 3TB 3.5" drives. Once you get to the 4TB 3.5" drives, the crown returns to slow spinning media though.

    A conventional HDD wouldn't fare much better. The typical service life of an enterprise HDD is 5 years after a storage period of no more than 6 months. Beyond that point, the MTBF numbers aren't valid. That doesn't mean the drive will immediately fail. But, conventional HDDs aren't meant to be stored for a long period of time. The lubricating medium (grease or oil) will start moving away from where it is supposed to be, so that parts which were supposed to be lubricated won't be lubricated. The lubricant may also start oxidizing, becoming less of a lubricant. I'm not sure that a drive sitting around for 5 years will be any worse than a drive which was operating for 5 years, but I wouldn't count on either to be around for 20 years, let alone 50.

    If you want to be sure those baby pictures will still be around to show their grandkids, best to print the pictures, as we have never developed a better archival storage device. Better yet, paint it in some obscure cave in France. If you want the time capsule information to be available, print it on archival paper with archival inks.

    I see an article in EE Times saying Samsung is producing flash NAND on their new 20nm FAB now and expects to begin running it at 10nm next year. Just passing it on, don't know how newsworthy it is. ET Times 10/10/2011 edition.

    Well you've made it this far. Hopefully you've learned something on the way.

    Here's the next path on your journey. http://bit.ly/nqPUwd

    Because I do video graphics and its really the only thing that slows my system down for any type of reference # on tests. Even with a 10,000 RPM drive I have 12gb of mem and I upgrade my processor every 3-4 years when I can but I really never think of the hard drive. But now I am seriously thinking about getting one of these.
    Oh and by the way guys I think that the collar of his shirt is stretched out because his head is so big and it has to stretch itself out cause of the big brain he has in it unlike ppl who are arguing about someone that is wearing a t-shirt on a hard drive review.
