CrystalDiskMark 3.0 Tests

CrystalDiskMark 3.0 is a file transfer and operational bandwidth benchmark tool from Crystal Dew World that offers performance transfer speed results using sequential, 512KB random, and 4KB random samples. For our test results chart below, the 4KB 32-Queue Depth read and write performance was measured using a 1000MB space. CrystalDiskMark requires that an active partition be set on the drive being tested, and all drives are formatted with NTFS on the Intel P67 chipset configured to use AHCI-mode. Benchmark Reviews uses CrystalDiskMark to illustrate operational IOPS performance with multiple threads. In addition to our other tests, this benchmark allows us to determine operational bandwidth under heavy load.

CrystalDiskMark uses compressed data, so sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance in this section.

CrystalDiskMark 3.0 reports sequential speeds reaching 486.8 MB/s reads and 326.2 MB/s writes. 512K test results reached 419.6 MB/s read and 322.2 MB/s write performance. 4K tests produced 32.01 read and 92.87 write performance. All CrystalDiskMark results produced by this 240GB OCZ Vertex 3.20 SSD were roughly equal to the previous-generation Vertex 3 series, yet trailed behind some recently released solid state drive products.

Maximum 4KB IOPS performance results at queue depth 32 are reported in the chart below. These values represent the performance levels for several enthusiast-level storage solutions, and illustrates which products offer the best operational performance under load:

In the next section, we continue our testing using Iometer to measure input/output performance...

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.
