Other highlights include no need for additional power and the Z-Drive R4 is bootable, removing the need for a system drive. Not very useful yet for the regular users without deep pockets. Max latency topped out at Our next test looks at random large-block transfers, but still keeping the 2MB transfer size. Be the first to review this item. Sign up now Username Password Remember Me.

Veeam Introduces Instance Licensing. Veeam Announces FY Results. The Test This is going to be a bit of a disappointing set of performance graphs as it is our first real foray into the world of enterprise SSD testing. OCZs track record over the past few years shows them to be no less than a leader in SSD innovation and much of what they have accomplished has yet to be matched by their competition. This also allows a more optimized data path, which has the side benefit of increasing storage performance. Our final section of enterprise synthetic benchmarks covers steady-state performance in our server profile tests. Our first enterprise trace covers a Microsoft Exchange mail-server environment. Another feature or lack of a feature is the Z-Drive R4 sources all of its power from the PCIe slot itself, instead of requiring an external power source connected.

Cooling is completely passive on the Z-Drive R4, utilizing cooling air from the case itself, pushing air from the front of the card, over the NAND serjes controllers, and out the grill that is part of the PCIe mounting bracket. Now we cant go back Looking at the same test with random 4K write activity, we measure performance again from an effective queue depth of 4 to This shows the two polar sides of real-world conditions where some data in a given environment can be repeating and compressed.

OCZ tells us eeries problems will be addressed in the final version of the drives due to ship in the coming weeks. In a straight line measurement the 1.

OCZ Z-Drive R4 SSD Review

Our next test looks at 4K random write performance at a static queue depth 3.tb 32 and results are recorded and averaged once the drives have reached steady-state. The table above simply highlights the standard configurations OCZ builds. If you are new to StorageReview, one thing we try to focus on is how any given drive might perform under real-world conditions.

We introduced the Z-Drive R4 in our Computex coverage earlier this year – it’s 3.2tbb beast. See any errors on this page?

In our Web Server scenario with read-only transfers, we measured speeds topping at roughlyIOPS with a single worker load from both compressible and incompressible data-types.


OCZ TB Z-Drive R4 C Series PCI Express Solid ZD4CMFHT

In this test we include: The Z-Drive R4 integrates seamlessly with servers at the system bus and kernel level, creating a new flash memory tier and dramatically increasing the throughput and application performance while slashing capital and operating costs. In our steady-state Workstation and Database profiles, we found that the R4 couldn’t be used to its fullest potential unless it had a multi-worker environment with certain compressible workloads.

This allowed us to fully saturate the Z-Drive R4 and reach speeds that the drive was advertised as being able to handle. The breakdown is as follows: Several months later, our re-review has does nothing but increase our admiration for what OCZ has done with the Z-Drive R4. We will use this review to begin assembling our enterprise SSD data and hopefully in the coming weeks and months we’ll be able to have a set equivalent to what we have in the consumer space.

The method we came up with which allowed us to still work with the drive in an unformatted setup was to have two managers and two workers interfaced with the same 5GB LBA segment.

This is subjective because the z-drive r4 is cheaper than the FIO drive. Be the first to review this item. We split the synthetic IOMeter testing portion of this review into two parts. Home Lab Horror Stories. We also have a new enterprise trace that we’ll roll out after the client-focused tests.

OCZ Z-Drive R4 CM88 (1.6TB PCIe SSD) Review

Suggestion to authors — test it just for fun. CPU Intel Core i7 running at 3. Reviews 0 Write a review xszwrqud. This section also includes our server profile tests, which from the start are designed to show how well enterprise products perform under demanding mixed server loads. We split the synthetic IOMeter testing portion of this review into two parts.

We also had to run the Z-Drive R4 on our old X58 testbed instead of our H67 system as it wouldn’t complete any tests on our H67 platform. Despite the spec table above, OCZ also offers customized solutions as I mentioned above.

OCZ Z-Drive R4 CM88 (TB) Overview – CNET

For today’s review OCZ sent us a 1. Public companies are under an even greater pressure to maintain high profit margins. Les Tokar September 27, 15 Comments. Let the storage wars begin! Veeam Announces FY Results. OCZ is also offering a tremendous amount of flexibility with the drive, there are both full height and half height options, with the full height R4 available in capacities of GB, 1.


It was so fast in fact, that it made us re-develop our testing platform to better accommodate the burgeoning PCIe SSD space, dedicating a testing platform specifically for enterprise storage solutions.

Intel Core i7 running at 3. When do you expect to have current hardware for live testing? The breakdown is as follows:. We kept the same drives in the lineup for our real-world benchmarks, although with our mail-server trace being released after the LSI WarpDrive was reviewed, it was not included in that test. Given the high price of this item, we opted to leave the daughter board attached since the symmetrical parts layout meant that we could easily identify even partially obscured electronics on the board.

This is what keeps my interest. We have put in a request to FusionIO for a competing solution however it appears to have fallen on deaf ears.

Our first ramped test looks at random 4K read performance as it scales from an effective queue depth of 4 to Home Lab Horror Stories. You might first ask yourself why it only topped out at k While IOPS performance is a good metric to measure steady-state performance, another key area of interest is around average and peak latency. This manages redundancy and acts as a software interface with the host system.

Increasing the load to four workers, transfer speeds stayed at 50, IOPS with incompressible data, while average latency jumped from the higher queue depths. The shrinking margins in the consumer SSD space will ultimately drive companies out of the business, consolidating power in those companies who are fine operating with slim margins.

Our second real-life test covers disk activity in a productivity scenario. Sorry, but thinking this through HP should donate some equipment or Dell as well as updating the cards and also add tests of real applications to see performance gains. The driver accumulates IOs and redestributes them to the drive’s controller array, to some degree, dynamically.
