OCZ Vertex 4 Review (128GB), Firmware 1.4/1.5 Tested


The latest Vertex 4 firmware updates provide a noticeable boost in sequential write speed at 128GB and 256GB capacities, and the low queue depth sequential read performance issue has also been fixed. Our primary complaints from the initial review, at...

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, while other drives continue to work at roughly the same speed as with...

OCZ Vertex 4 256GB Solid State Drive


We've looked at many SSDs here, and they've mostly been implementations of the popular SandForce NAND controller. While this isn't a bad thing, as the performance offered by those drives have been good, it's good to see more competition in the growing...

OCZ Vertex 4 256 GB Solid State Hard Drive SSD Review


The Vertex 4 is a departure from OCZ's tried and true model of using third party controllers and firmware for its SSDs. Taking control of the firmware with the Vertex 4 gives OCZ the ability to tune the SSDs for speed and performance at lower queue...

It is worth mentioning that the OCZ Vertex 4 has been on the market since April of this year, so it is hardly a newcomer compared to some of the SSDs we have directly compared it to. Seeing that it has been selling for six months and still shows to be...


best in its class

OCZ Vertex 4 256GB Solid State Drive


A while ago, there was a Hong Kong serial drama called "Links to Temptation". Frankly, it has one of the worst storylines I have ever seen. It begins with a barrister who travels to Macau with his family, and encounters a pole dancer of whom he falls...

OCZ Vertex 4 SSD Revisited: 128GB and New Firmware


OCZ Vertex 4 SSDs (256GB and 512GB) through the benchmark grinder to see what they could do and also told you everything you ever wanted to know about them in the process. Today, we're testing another brother in the family, the 128GB OCZ Vertex 4. When...

Excellent price and value ; 5-year warranty ; Much better sequential reads with firmware update

Weak write performance in some tests ; Larger-capacity V4s offer same value, better performance

To put it succinctly, the 128GB Vertex 4 delivered somewhat of a mixed bag of performance results. In some tests it bested the field, while in others it couldn't keep pace. Like the previous Vertex 4s, the 128GB version didn’t do very well in SANDRA, a...

OCZ Vertex 4 128GB review (firmware 1.5)


For years now, Vertex name is the one people talk about when talking about fast SSDs. OCZ has been on the forefront of SSD technology since the very beginning, and - so has Vertex as a "brand". Over the years, they've developed other very popular and...

We can actually draw several conclusions from this test. First and foremost, this drive is not only fast, but it's consistently fast, which is something that you can't say about many SSD's. Reads and writes are very comparable across the board, access...

OCZ Vertex 4 128/256 GB and New Firmware 1.5


Flagship solid state drives from OCZ – Vertex 4 – underwent yet another spec modification caused by the release of the new firmware version 1.5. Therefore, we decided to retest the “updated” Vertex 4 SSDs and try to figure out the reasons behind the...

We were very pleased with the OCZ Vertex 4 series, based on the Everest 2 controller, in our previous review. Being rather affordable, these SSDs almost matched the performance of top-end SSDs with other controllers and seemed to lack just a little to...

OCZ Vertex 4 128 GB: Revisiting Write Performance With Firmware 1.5


In our recent look at the Vertex 4 SSD equipped with firmware 1.4, we found that the 128 GB drive's write performance depended heavily on available capacity. OCZ disagreed, but then quickly rolled out firmware 1.5. So, we're back to test the new build.

OCZ Vertex 4 256GB SSD w/1.5 Performance Update


As some of you already know, at the heart of the Vertex 4 is an “Indilinx Infused” SSD flash processor called the Everest II. This dual core ARM processor is based on Marvell silicon and “Infused” with OCZ's own Indilinx proprietary firmware. This is...

OCZ Vertex 4 240GB SATA 6Gbit/s SSD Review


The Vertex is back, and this time it features more OCZ than ever before! (No, we're not kidding.) Powered by its latest Everest 2 platform, the Vertex 4 is a completely in-house SSD that not only brings Indilinx back to the table, but very well has the...

It should be noted that the launch firmware for the Vertex 4 was revision 1.3.X, and OCZ has since released the update (the firmware utilized in our test sample). Amongst other things this version especially improves the Vertex 4's performance...
