OCZ Z-Drive R4 C PCI Express 1.6TB SSD Review – OCZ Z-Drive R4 versus FUSION-IO ioDrive Duo

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

OCZ Z-DRIVE R4 C SERIES PCI EXPRESS 1.6TB SSD

FUSION-IO IODRIVE DUO PCI-EXPRESS 640GB SSD

ANALYSIS

We need to keep in mind that ATTO tests with compressible data.  This results in the highest performance result possible which is why it is preferred by manufacturers to determine product specifications.  Experienced data storage managers will understand that knowledge of their own server environment is a key factor in understanding the proper storage device to purchase for that system.

Having said that, the Z-R4 results of 2.87GB read and 2.81 GB write performance easily surpass that of the 1.62GB/s read and 1GB/s write results of the io-D (when testing compressible data) and both results do match that of their product specifications.  An absolutely incredible thought is that the Z-Drive doubles this score with the addition of another of OCZs proprietary Superscale Storage Controller.

Would be more fair if you compared it to the 1.28 TiB variant of the Duo.
Brilliant article none the less…

I agree totally but we have to work with the hardware that we have access to. As for the compliment of it being a brilliant article, totally unexpected and thank you very much.

“we have to work with the hardware that we have access to”

OK, so you have access to the fastest OCZ hardware but not the fastest FIO hardware…and this makes for a subjective test? Seriously? When do you expect to have current hardware for live testing? Any chance we might get actual server-side testing to show off the true strength of FIO hardware and, more importantly, software? Oh wait, then we couldn’t have a test could we…you’d need a competitor other than OCZ….

WE would be pleased to hear suggestions as to other sources of competition for the card. Thanks ahead.

not sure why the harsh response or love affair with Fusion. Why do you care which company? I say Fusion should put up the hardware like OCZ and do real life tests within applications. Both companies can put there money where their mouth is.

Harsh response? Love affair? I guess I am a bit confused because, well, myself, when I read an article I want to know the reviewers opinion and feelings just as much as I do facts alone. This is what keeps my interest. It is also an important factor to help the reader. Take for instance the stuttering 602 controller a few years back. Can you imagine a reviewer saying, ” The drive stalls and stutters a bit but is still a large step up from a hard drive” Say it like it is I believe and hope our fellow members… Read more »

This is subjective because the z-drive r4 is cheaper than the FIO drive.

You find it subjective because one performs alot better yet is alot cheaper? How so?

Finally SSDs start approaching the RAM speeds. Not very useful yet for the regular users without deep pockets. So meantime we still get 2-5 times of these speeds with software based QSoft RAMDrive and, thanks to DRAM price drop, at the $5/GB. While many even never heard of that but we are enjoying such crazy RAMDrives’ speeds for our apps for almost a quarter of century since the DOS times. Suggestion to authors – test it just for fun. The latest QSoft Enterprise edition or one of Romex Software have a lot of nice functions allowing to auto backup the… Read more »

nice review. I like both of these companies, but I think you need to compare the iodrive II DUO if you really want to compare head to head what each manufacture would put against another. Another addition that would be nice is to see performance of actual work like indexed data using lucene. What is the performance gain on these working enviornments.

We have been in contact with FusionIO during CES and just may be able to appease your request soon enough.

OCZ Z-R5 is also coming

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. This was a great article none the less. Thank You
