OCZ Vertex 3.20 Conclusion

Iometer IOPS Performance

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. Iometer does for a computer's I/O subsystem what a dynamometer does for an engine: it measures performance under a controlled load. Iometer was originally developed by the Intel Corporation and formerly known as "Galileo". Intel has discontinued work on Iometer, and has gifted it to the Open Source Development Lab (OSDL). There is currently a new version of Iometer in beta form, which adds several new test dimensions for SSDs.

Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.

To measure random I/O response time as well as total I/O's per second, Iometer is set to use 4KB file size chunks over a 100% random sequential distribution at a queue depth of 32 outstanding I/O's per target. The tests are given a 50% read and 50% write distribution. While this pattern may not match traditional 'server' or 'workstation' profiles, it illustrates a single point of reference relative to our product field.

All of our SSD tests used Iometer 1.1.0 (build 08-Nov-2010) by Intel Corporation to measure IOPS performance, using a SandForce-created QD30 configuration: 4KB 100 Random 50-50 Read and Write.icf. The chart below illustrates combined random read and write IOPS over a 120-second Iometer test phase, where highest I/O total is preferred:


In our Iometer tests, which are configured to use 32 outstanding I/O's per target and random 50/50 read/write distribution, SandForce SSDs generally outperform the competition when tested with this large queue depth. The OCZ Vertex 4 SSD delivered the best combined IOPS performance we've seen from any SATA-based SSD with 83,494, followed by the Intel SSD 520 Series at 80,433 peak combined IOPS, then the Intel SSD 335 Series with 80,015. This 240GB OCZ Vertex 3.20 solid state drive produced 56,135 IOPS, keeping pace with the OCZ Vector SSD. The 120GB OCZ Vertex 3.20 solid state drive trailed behind because of its lower capacity, which limited it to producing only 32,711 combined IOPS.

It should be noted that nearly all modern SSDs deliver I/O far beyond the needs of multi-tasking power users and hardcore gamers, and would be ideal for workstation systems running utilizing virtual machines.

In our next section, we test linear read and write bandwidth performance and compare its speed against several other top storage products using EVEREST Disk Benchmark. Benchmark Reviews feels that linear tests are excellent for rating SSDs, however HDDs are put at a disadvantage with these tests whenever capacity is high.

There was an article not too long ago that OCZ was going out of business.
Are they or not? They keep coming out with new products so apparently not.
I'd forward the article but now I can't find it.

You can't find it because we never wrote that OCZ was going out of business. We did write about their layoffs and stock value about seven months ago:

I'm most impressed by the benchmark results for the Vertex 4, which are consistently at or near the top of every test, and well above the 3.20.

I'm disappointed not to see any RAID configurations thrown into the mix (most notably, how a Raid-0 of the 120 compares to a single 240.)

Almost nobody purchases a SSD to put it into a RAID-0 array, so obtaining a second drive for the sake of pleasing 1/10000 of the readers wouldn't make a lot of sense.

Begging your pardon, but that's a pretty stupid reply.

With a 120GB SSD running at almost exactly have the price as it's 240GB older brother, the possible performance increase over running two 120's over two SATA-III ports vs running a single 240 over just one SATA-III port, seems a bit near-sided.

as far as i know in raid-0-mode trim and other vital features do not work

# Trim, RAID 0, Z77Bruce 2013-05-28 08:50
The Z77 Intel Chipset supports Trim with RAID. It's a shame that it only supports two SATA 6Gb/s ports, limiting RAID options to RAID 0 or RAID 1.

You do know that the only storage capacity running a pair of 120GB ssd's in RAID-0 is 120GB don't you?
You only obtain a faster speed and still have only the capacity of one 120GB ssd. The designation "240 GB's" is meaningless when describing this.
Paying twice just for a bump in speed is what's completely stupid.
If you lose one drive then you lose the info on both drives in RAID-0.
RAID-0 is just fine for hdd's to get a worthwhile gain in speed.
For SSD's the speed increase is not worth the expense. Just a complete waste of money.
I use 500 GB Samsung SSD's and don't RAID them. They're more than fast enough as is and running a pair in RAID-0 would just be ludicrous.
I own 5 of these, so far, that cost $319.99 each. I am more than happy with their speed as is.
If it were possible, all I would do is run them as JBOD. Same speed but double capacity.

Raid-0 is not redundant. It is simple "striping", so you will have all 240GB available. (only Raid levels above 0 that allocate one drive just for recovery "wastes" a drive.)

I'm not sure what you're talking about. But then again, neither do you.

The pitfalls of using Raid-0 (lose one drive and lose everything) is the same whether you use SSDs or HDDs. I ran Raid-0 with two HDDs for years with no problem. SSDs are (no longer) more susceptible to failure than most HDDs.

You claim Raiding SSDs is "not worth the expense", but with two 120GB going for $240 and a single 240GB going for $220, the "expense" is only $20 whereas the performance gains might more than justify the extra money (but we don't know b/c they never tested it.)

Whether YOU are satisfied with the speed of your single SSDs is a matter of usage and personal preference. *I* however edit LARGE A/V files frequently that would greatly benefit from the faster Read/Write speeds of Raid-0.
