OCZ Vertex 3.20 Conclusion

ATTO Disk Benchmark

The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.

ATTO Disk Benchmark: Queue Depth 4 (Default)

Our bandwidth speed tests begin with the 240GB OCZ Vertex 3.20 solid state drive attached to the Intel P67-Express SATA 6Gb/s controller operating in AHCI mode. Using the ATTO Disk Benchmark tool, the test drive performs basic file transfers ranging from 0.5 KB to 8192 KB.

The 240GB model provided to Benchmark Reviews for testing produced 554 MBps maximum read speeds that plateau from around 1024-8192 KB file chunks, and 528 MBps peak write bandwidth that plateaus from 512-8192 KB. These results agree with OCZ's performance specifications of 550/520 MBps for all 120/240GB Vertex 3.20 SSDs.

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 never mentioned that it was you that wrote the article. Never!

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-0Mugsy 2013-05-28 08:45
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.
