OCZ Vertex 4 Indilinx Everest 2-Infused SSD

19 thumbs up

Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. Out testbed's motherboard was updated with the latest BIOS available as of press time and AHCI (or RAID) mode was enabled. The SSDs were secure erased and left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO, PCMark 7, and CrystalDiskMark benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test.

I/O Subsystem Measurement Tool

As we've noted in previous SSD articles, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real-world performance for the average end user. That said, we do think IOMeter is a reliable gauge for relative available throughput within a given storage solution. In addition there are certain higher-end workloads you can place on a drive with IOMeter, that you an't with most other storage benchmark tools available currently.

In the following tables, we're showing two sets of access patterns; our custom Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and IOMeter's default access pattern of 2K transfers, 67% reads (34% writes) and 100% random access.

The OCZ Vertex 4 drives performed very well, leading the other drives, when using IOMeter's default access pattern, which uses small 2K transfer size and 100% random access. With out custom access pattern that uses a somewhat larger transfer size and a mix of random and sequential access, however, the Vertex 4 drives stumble a bit and land somewhere around the middle of the pack.

In terms of total transfers, we see a similar trend. The OCZ Vertex 4 offers best of class bandwidth with the default access pattern, but middling performance with our custom test.

SiSoft SANDRA 2011
Synthetic HDD Benchmarking

Next we ran SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting and read and write performance metrics are detailed below.

Things seemingly take a turn for the worse in the SiSoft SANDRA physical disk test. The new Vertex 4's trail the pack in terms of read bandwidth, but put up excellent write numbers. We do not, however, thing these read scores translate into a real-world performance penalty. We'll explain a little later.

Very nice. I was kind of a SSD refusenic and actually for a while regretted buying an OCZ Vertex 4 for a while. I kept on trying to figure out how to get rid of, but eventually just gave up and installed it and...I can't go back to normal HDs anymore...

What I did was when upgrading to Windows 7, I installed Windows on the SSD, and used my old HD as the other partition for games and whatnot. Windows completely boots in about 7 seconds or so. The difference became more apparent when I bought a cheap laptop for school with a regular HD, and waiting for this thing to boot up is now torture compared to my desktop.

Anyway, nice review but for me it seems like the price doesn't climb proportionally to how much the space increases, so I think I'll stick smaller ones just for a Windows partition and regular HD for everything else.

Thanks for the review Marco I've been waiting for this one. Ever since they announced they were going back to the Indilinx controllers it's had my attention. After seeing the octane's performance I was skeptical the Vertex 4 would break any records. I'm glad to see it's performance is up there but like you said the vertex line means speed and I was expecting it to beat the vertex 3 in all categories and sit as top dog. On the plus side it looks like ocz is really benefitting from their Indilinx purchase. It will be interesting to see if they convert the agility line over to the new controller as well.

Good review Marco. These are good performers. The SSD market is really changing fast these days. Prices are going south and performance keeps getting better too.

Also,.....the SanDisk Extreme SSD drives are really looking good to me.
