OCZ Vertex 4 SATA 3 SSD Review – Indilinx Infused and Game Changing Performance Results

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. The 512GB result is on the left with 256GB on the right:

Specifications list 535MB/s read and 475MB/s write for the 512GB version and 535MB/s read and 380MB/s write for the 256GB version which is in line with what we are seeing here.  This was a bit unexpected simply because ATTO favors the use of highly compressible data in its testing and we expected a performance drop.   Adjusting the Queue Depth in ATTO testing shows no change in performance.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible.For our testing today, we will concentrate on testing with incompressible data samples and the 512GB will be shown on the left with 256GB on the right.

Our Crystal Diskmark results typically fall below that of ATTO which is normal but we thought the high sequential and 512k read results of the 512GB drive were a bit low.  What was really nice to see was a low 4k score above 100MB/s on the 512GB Vertex 4.

AS SSD BENCHMARK VER 1.64

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the worst case scenario in SSD transfer speeds while using SandForce Driven SSDs as they use compression in storage as discussed earlier.  Many enthusiasts like to benchmark with AS SSD for their needs.

V4 512GB SSD

This is perhaps the best result that I have seen in AS SSD and definitely shows the strengths of the Vertex 4 512GB SSD.  Every aspect that a reviewer looks for is taken care of here; great high sequentials, dynamite low 4k speeds, equal and high IOPS and great disk access time.  This result is something that enthusiasts have been in search for since SSDs joined the consumer storage scene.

Nice numbers but I’ll be waiting until after the first firmware rev comes out before diving in. The 512Gb pricing is very attractive and makes the V3 480 price look pretty ridiculous. I’ll be curious how these bad boys handle RAID 0.

You’ll find loads of benchies here…;)

It’s a barn burner for sure…

Nice benchmarks… bit of tweaking on those benches as well. Did I see a 150+ 4k random write?

“OCZ Technology is standing by the Vertex 4 with a five year warranty”
“…the fact that the Vertex 4 has an industry leading four year warranty.

So is it four or five?

It’s five, but either way 5 isn’t industry leading with Intel,Plextor, and OWC beating them to the 5 year warranty by a long time. This was surely a reaction to the upmarket brands offering two more years of coverage than everyone else.

So it’s good, but it’s not industry-leading… that would be 5 years and 1 day of coverage ;).

Give the fw a few months and throw in some 24nm toggle and watch me pounce. 4 sho

I like the specs on the 512GB version very much. If we can see above 550MB/s read and write on future releases then I will be truly impressed.
