AnandTech Storage Bench 2011 - Light Workload

Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).

The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:

Light Workload 2011 - Average Data Rate

Our light workload is far more representative of a mainstream client workload (read heavy) and this is where the Vertex 4's sequential read performance hurts it the most. The Samsung SSD 830 ends up being considerably faster here. Once again, if we look at the breakdown of reads and writes we see why:

Light Workload 2011 - Average Write Speed

Read performance is around half of the best performers, while write speed is around 30% better. The combination results in competitive but not class-leading performance.If OCZ is able to deliver, at a minimum, Octane levels of read performance, the Vertex 4 should find itself much higher in the overall charts.

    It's still a drive from OCZ, a company that has repeatedly and blatantly used its customer base as unpaid beta testers, and lambasted them when they dared to complain about it. No thank you. The fastest drive in the world is of no use to me if it's causing my computer to BSOD constantly. I'll be spending my money and that of my many clients on drives with proven track records for reliability and excellent customer service, both sadly lacking in OCZ products. Reply

    Ocz is the only one that actually got to the bottom of the bsod screen on sandforce. In the end it was sandforce fault because they made the controller. All the other companies waited and then used the fix. Intel is the exception who waited a whole year before releasing them to validate but they still use sandforce controllers. Vertex4 is the 1st time that ocz now owns the controller and firmware that goes into the product. I hope this will prove to be better and have quicker fixes. Ocz is always the first to release the technology so expect some issues, but thats what people take for early adopting. I had 5 vertex 1 die on me and then they upgraded me to a vertex2. Just purchased the 4 so hope all goes well. Reply

    "Ocz is the only one that actually got to the bottom of the bsod screen on sandforce."

    Actually that was intel.

    Not true. Ocz pushed sandforce to finally find the issue based on what the users were telling ocz while sandforce kept trying to deny the issue and could not find it in a lab environment. If you see further down I said intel waited a year with validation going on. Reply

    You have no idea about ssd validation if you think Ocz pushed sandforce for BSOD.The fact is that Intel found this and kept sandforce busy with fixing the issue while ocz even though knowing the issue release agility 3. Anyways doesn't matter who takes the credit, people know where to go when it comes to reliability. Reply

    you do realize intel 520s are now getting bsods?! Reply

    You go to Samsung for reliability. Iceman is correct, word is spreading of more 520 stability issues. If you want the fastest, most reliable SSD get the 830 as Anand recommends. Reply

    At work we have deployed about 50 - 80GB Intel 320 Series Drives and so far nearly 60 - 64GB Samsung 830 Drives. The Samsung drives are screamers but we've seen a lot of strange issues with the Samsung drives that we never had with the Intel drives. We have not had a single drive from either company fail or come DOA. That amazes me personally, not a single dud. We've literally had dozens of faculty members come ask us what we did to their computer that made it so fast all of a sudden. The issues we've had with the Samsung drives about 1 in 10 causes Windows mini-setup to freeze. We re-image the drive again it works just fine. We are thinking maybe the compatibility with some SATA controllers isn't as robust on the Samsung drives as it is on the Intel drives. Reply

    Or choose a SSD with a marvell controller like the Corsair Performance Pro or Plextor M3P. Both are fast and stable. I would never choose a SSD with sandforce again after using a vertex 3 for a while with lot or problems and i'm obviously not the only one. Reply
