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. As for the compliment of it being a brilliant article, totally unexpected and thank you very much. Flash performance changes the longer you write to a drive and speeds taper down until the drive hits its steady state speed. Our next test looks at random large-block transfers, but still keeping the 2MB transfer size. For today’s review OCZ sent us a 1. The R-series boards have an array of capacitors that can store enough charge to flush all pending writes to the NAND arrays in the event of a power failure. Our next test looks at 4K random write performance at a static queue depth of 32 and results are recorded and averaged once the drives have reached steady-state.

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. We split the synthetic IOMeter testing portion of this review into two parts. The R-series boards have an array of capacitors that can store enough charge to flush all pending writes to the NAND arrays in the event of a power failure. The Z-Drive R4 also leverages an efficient power management system that requires less cooling 90 vs LFM and less power. The breakdown is as follows: This was a great article none the less.

This section is designed to show how well esries products perform under different demanding mixed workloads. The Fusion-io drive we just reviewed requires a secondary power source for full performance.

OCZ Z-Drive R4 SSD Review

This item is nonreturnable. Our final section of enterprise synthetic benchmarks covers steady-state performance in our server profile tests. It really comes down to analyzing your current workloads and seeries the best PCIe solution that fits application requirements.

Both companies can put there money where their mouth is. To see how well it performed in straight-line performance we used IOMeter with a 4K-aligned sequential 2MB transfer test, with an effective queue depth rate of 4.


The Z-Drive R4 has ultra-high endurance for enterprise applications. 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. Enter new zip code to refresh estimated delivery time.

With countless variants the Z-Drive R4 offers class-leading performance with a custom configuration for nearly any application. For esries that want a Z-Drive R4 for a specific use, OCZ offers plenty of configuration options, including specialized models. The breakdown is as follows:.

Apricorn Aegis Secure Key 3z Review. For all intents and purposes this test shows drive performance under normal daily activity for most users. A single mm wafer only has a surface area of mm 2 even less z-driv usablewhich means it takes more than half of a mm 25nm MLC NAND wafer to supply the flash for just one of these drives.

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

Public companies are under an even greater pressure to maintain high profit margins. We captured the activity of our StorageReview mail server over a period of a few days. Other highlights include no need for additional power and the Z-Drive R4 is bootable, removing the need for a system drive.

CPU Intel Core i7 running at 3. OCZ did a great job from a design perspective, keeping the parts within the boundaries of the card to minimize interference with other devices installed within the computer. In an enterprise setting, initial burst is hardly relevant if after one hour of use the drive won’t see that speed again. You find it subjective because one performs alot better yet is alot cheaper?

The main difference between both of these models, besides physical card height, is the number of SandForce SF processors. The Z-Drive R4 also leverages an efficient power management system that requires less cooling 90 vs LFM and less power. This review is of the 1. Despite the spec table above, OCZ also offers customized solutions as I mentioned above. OCZ attributes this to an issue with the preproduction Z-Drive boards which it says will be corrected by the time mass production begins.


Up to bits correctable per byte sector Data path parity protection. Eaton 9PX Battery Replacement. This is what keeps my interest. With the maximum power usage figure of 26w, the R4 is rated for just 90 LFM of air to stay within its operating temperature range under load. 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. After that point the R4 quickly ramps up to its top recorded speed.

Our first enterprise trace covers a Microsoft Exchange mail-server environment. Post Your Comment Please log in or sign up to comment. The table above simply highlights the standard configurations OCZ builds.

Our second real-life test covers disk activity in a productivity scenario. Our first ramped test looks at random 4K read performance as it scales from an effective queue depth of 4 to The difference between the Z-Drive R4 and ioDrive Duo become very apparent in the expanded random 4K read and write test. We have put in a request to FusionIO for a competing solution however it appears to have fallen on deaf ears.

OCZ Z-Drive R4 CM88 (3.2TB)

This was a great article none the less. The trace captures the heavy read activity of each game loading from the start, as well as textures as the game progresses. The breakdown is as follows:
