It was only last month that I reviewed the OCZ Vertex 4. A lot can happen in a month and this was certainly the case with OCZ's new flagship consumer grade SSD, the Vertex 4.
Every single reviewer on the Internet assumed that the words "Indilinx Infused" meant that the Everest 2 controller was a completely in house design from Indilinx. OCZ never claimed this, but it turns out the silicon is in fact a proprietary Marvell controller, and the firmware is Indilinx. In actual fact it doesn't matter, as to me what is important is how the drive performs, and how stable the drive is in everyday use.
So here we are, one month down the line, and OCZ is about to release a new firmware for the Vertex 4. The review sample I have is the 512GB version which is already an awesome performer, in fact the fastest SSD I have tested here at MyCE.com. When I tested the Vertex 4 last month I couldn't find any real performance issues. Partly this was due to how I test SSDs. I tend to test in a manner that I think is important to the majority of MyCE members, and there is a great many of us who edit video, graphics, and audio.
In any case, in my original Vertex review I failed to highlight that low queue depth (QD1) sequential reading performance with the original Vertex 4 shipping firmware wasn't very good, in fact it was decidedly subpar. I had noted that overall sequential reading performance could be better, but that should not excuse me from failing to find a weak point in an SSD. However, it's a lesson learned.
With firmware version 1.4, OCZ have raised the bar again. The 128GB and 256GB models will see the largest performance increase, but even the already blazingly fast 512GB model will also see some performance gains. Adding to the impressive figures below, low queue depth (QD1) sequential reading performance will also receive a boost with the new firmware.
Okay, let's get on with the testing. For this article there simply wasn't time to run a full set of tests, but I also thought it was important to run enough tests with the new firmware to make sure the results were representative of the performance the end user can expect to get when updating to firmware 1.4
Note: The 1.4 firmware update is a destructive flash. Make sure you backup all important data before flashing.
