Solid State Drives, better known as SSDs, have become increasingly popular thanks to the likes of OCZ Technology. As a power house in the industry for all things DRAM related, OCZ has 8 models of SSDs available on their website each with two or three drive capacities. While SSDs have been commonly known for lower power consumption and heat, particularly important when it comes to flash memory for cameras or camcorders, SSDs used in notebooks and PCs today don't have the same concerns. An 800W power supply will power many hard drives and your one 4870X2 probably generates more heat than the combined number of SSDs you could afford.

Solid State Drives are primarily purchased for one reason: speed. Hard drives haven't changed in technology for quite a number of years but the new SSDs have evolved from the first generation into lightning quick response times and high speed bandwidth. The first evolution of affordable SSDs were plagued. After a bit of use, they would eventually bog down your system to performance levels slower than your average SATA. The OCZ Vertex with the Indilinx Barefoot controller aims to resolve that and provide consistent performance regardless of whether or not your drive is brand new or well-aged like a fine wine.

Page 2 : OCZ Vertex Package & Contents

I received the OCZ 30GB Vertex in its retail packaging. It promptly displays what the Vertex drive looks like but on the list of features the first line is ‘New, Faster SATA II Access Time’. This can basically be attributed to the 64MB Cache listed as the second key feature. The back of the package gives a breakdown of the specifications and a paragraph marketing the Vertex.

The sides of the box re-iterate the product name so we're going to skip those photos and jump right into the internal packaging. The Vertex is packaged almost identical to the G.Skill Falcon earlier reviewed. The second box completely surrounds the drive with foam to protect it from bumps and drops during transportation.

With the exception of the hard drive, the only other item with the packaging is an instruction and warranty manual. Surprisingly, there is no jumper included in the package to assist in firmware flashing.

The drive is protected in an anti-static plastic bag and by removing this we get our first good look at the OCZ Vertex. The front is pretty bland and the underside displays some technical information about the Vertex and its capacity.

Since the Vertex is 2.5′ and really intended for a notebook the power and data connection points are oriented as such. We can clearly see the two pings used for flashing the firmware on the second image.

Taken directly from OCZ's Vertex webpage:

Offering your system the incredible performance of flash-based storage, the OCZ Vertex Series delivers the performance and reliability of SSDs at less price per gigabyte than other high speed offerings currently on the market. The OCZ Vertex Series is the result of all the latest breakthroughs in SSD technology, including new architecture and controller design, blazing read/write speeds, and 64MB of onboard cache.

Perfect for notebooks and desktops alike, the Vertex Series is ideal for energy-efficient mobile computing to extend battery life, increase the speed of access time, and provide a durable alternative to conventional hard disc drives with superior shock resistance. High capacities and low power consuming NAND flash technology provide the necessary performance and battery life boosts generated by the proliferation of mobile gaming and new ultra-thin laptops.

The OCZ Vertex drives feature a durable yet lightweight alloy housing, and because OCZ SSDs have no moving parts, the drives are more rugged than traditional hard drives. Designed for ultimate reliability, Vertex Series SSDs have an excellent 1.5 million hour mean time before failure (MTBF) ensuring peace of mind over the long term. All Vertex Series SSD drives come backed a two year warranty and OCZ's legendary service and support.

By now just about everyone knows that OCZ is using the Indilinx Barefoot controller. Indilinx claims it supports up to 256GB with performance in the range of 230MB/s read and 170MB/s write which is in the same range as the Vertex depending on which model you own.

Page 4 : Installation, Power Consumption & Test Configuration

If you're interested in buying the Vertex SSD or any SSD for that matter, you must already know how to install a 2.5′ hard drive. For laptops, the drive needs to be mounted onto your hard drive cage and pushed into the bay. For desktop PCs, you'll need to purchase a 3.5′ to 2.5′ drive bay converter, screw the drive into place and plug in the SATA data cable and power.

I compared the power consumption of the Vertex to a few other SSDs and a conventional 500GB Seagate hard drive. With no surprise, the SSDs are a few watts below the conventional hard drive. It also appears that the Indilinx controller requires a few more watts than the original JMicron controller.

I will be testing the OCZ Vertex on my test bed as the primary drive with the OS installed on it. Here's my system specification:


  • CPU: Intel C2D Q6600 (G0 SLACR L731B434) @ 2.71 GHz

  • MB: Asus P5E3-Dlx Wifi-AP Edition
  • GPU: Sapphire HD 4850 X2 Catalyst
  • RAM: Aeneon 2×2GB XTune DDR3-1600 (AXH860UD20-16H) @ 1800Mhz 10-10-10-30 1T
  • PSU: Cooler Master Real Power Pro 850W
  • CPU Cooling: Thermalright HR-01 w/ 120mm Antec Tri-Cool Fan
  • PWM/NB/SB Cooling: Stock/Stock/Stock
  • OS: Windows Vista x64

Hard Drives

  • OCZ 30GB Vertex SSD (OCZSSD2-1VTX30G)

  • G.Skill 64GB Falcon (FM-25S2S-64GBF1)
  • G.Skill FM-25S2S-64GB
  • Seagate Barracuda SATA 500GB 7200.11 (ST3500320AS)

To test out the drive we'll be using DiskBench, Crystal DiskMark, SiSoft Sandra, HD Tune 3.10, ATTO, HDTach, IOMeter and Boot Timer. All benchmarks were executed 5 times and the average result was recorded. The system was reset between each benchmark.

To add a little flavour to the review, I'm going to benchmark the OCZ Vertex twice – once when the drive has only Windows Vista and the benchmarking software installed, denoted ‘New’ in the benchmarks, and once when the drive is completely full with files then deleted to make room for the benchmark test files. These results will be denoted ‘Full’. I'm doing this to see what the performance impact is once the drive is full of files.

Page 5 : ATTO, Crystal Disk Mark & Disk Benchmark Performance

ATTO Disk Benchmark

ATTO Disk Benchmark is probably one of the gold standards when it comes to drive performance. The software itself is fairly old but it works, measuring transfer rates at different transfer sizes for a file being 256MB in size.

The OCZ Vertex is off to a very strong start, almost 50% faster than the JMicron MLC SSD. It is a few MB/s slower than the G.Skill Falcon which also uses the Indilinx Barefoot controller but the difference is negligible at these rates. We're talking maybe needing to wait an extra second or two for a file transfer to complete.

Crystal Disk Mark

Crystal Disk Mark is another disk benchmark software commonly used, unlike ATTO Disk Benchmark, Crystal Disk Mark is our first look at sequential transfer rates as well as 4KB and 512KB Random transfer rates.

Crystal Disk Mark Sequential Read didn't give a realistic number; it was in the thousands of megabytes per second. We can see that the 4KB random read and write performance doubled over the JMicron controller. Once the drive was full, the write performance for the Vertex at 512KB Random and Sequential shows little difference and actually falls back in the ranking.

Nodesoft Disk Benchmark

There's nothing fancy to DiskBench, I commonly use it to see how long it takes to copy a file from one source to another. Seeing as this is a hard drive review, I'm going to use the ‘Create File’ feature and determine the speed at which the hard drive is able to create a 200MB file consisting of 100 2MB blocks.

Page 6 : Sisoft Sandra, HD Tune, HD Tach Performance

Sisoft Sandra – File System

Another common benchmarking program, we have SiSoft Sandra File System Benchmark. The File System Benchmark gives us a quick glance at the overall performance and whether we have a new or full drive, the performance is both consistent and miles ahead of the JMicron SSD or conventional platter hard drives.

SiSoft Sandra – Physical Disk

The Physical Disk Benchmark benchmarks the hard disks and not the file system, meaning the graph below compares the performance of the physical disk to the storage adapter, unlike the SiSoft Sandra File System benchmarks which shows performance between the file system itself and the adapter.

HD Tune

Yet another hard disk utility to determine the performance of your drive. HD Tune runs a few tests to provide a transfer rate (minimum, maximum and average). It also trends the performance through the entire disk and gives you the access time, burst rate and CPU usage.

HD Tach

HD Tach is a low level hardware benchmark for random access read and writes. The performance numbers are quite similar to HD Tune.

Page 7 : IOMeter & Boot Time


IOMeter is the latest addition to my hard drive benchmarking suite. The software is highly customizable and what I'm doing only scratches the surface of its capability. I added IOMeter because of flaws in the original solid state drives on the market. After completing all the benchmarks on my first JMicron SSD, I popped into my laptop and made it my day-to-day drive. I found overtime the performance to become really sluggish. At first, MSN messages would take longer to appear and videos would stutter. After some digging on the net, it turned out to be a problem with the random write performance. More information on the issue at hand can be found at AnandTech.

With IOMeter, I set the program up to pepper the drive with a 1GB file with 4KB record sizes, 100% random (as opposed to 100% sequential), 50% read and 50% write for 3 minutes. I generated results for average read and write access times and average read and write transfer rates.

ocz vertex benchmark

It's clear that with an average write response time of 6.114 seconds on the JMicron controller compared to 0.062ms from the OCZ Vertex the system will stutter. Even the read and write performances are factors higher with the OCZ Vertex.

Boot Time

With SSD comes the reduction of start-up times. Basically every application will load up a tiny bit quicker. The performance is very much related to how fast the drive is able to read random files scattered throughout your drive required for load up and how many operations it can handle at once. The higher these two throughputs, the faster programs will load. With the OCZ Vertex, we've got a good lead over the original JMicron controller and the G.Skill Falcon.

Page 8 : Conclusion

To an unknown user, the OCZ Vertex appears to be like all the other OCZ Solid State Drives. It's a black box with an adhesive label indicating the series and capacity. Function comes first in my books over form and the OCZ Vertex does exactly that. Once installed in your PC or notebook, it'll rarely see the light of day but under the hood is a powerful engine waiting to roar to life.

The OCZ Vertex is leaps and bounds better than the original JMicron Solid State Drive. If you're an owner of the first generation drives and noticing your performance and system is starting to fall behind, it is time for an upgrade. I was originally pleased with the JMicron MLC SSD but after a few short weeks of use my notebook started to hang for a few seconds at a time. As OCZ clearly indicated on their packaging, my OCZ Vertex gives me faster access times resulting in a far more stable machine. The 64MB cache has made a world of difference and OCZ didn't sacrifice too much bandwidth for the improved access time. We're still well into the 140MB/s Write and 200MB/s Read. With Win7 just around the corner and the OCZ Vertex already claiming to support the TRIM command, OCZ's Vertex has a very bright future ahead of itself.



  • Significant improvement over first generation SSDs

  • New controller with cache provides significant reduction in random access times
  • Vertex family has up to 250GB capacity


  • Premium price

  • Power consumption increased with new controller and cache

I'd like to thank OCZ for making this review possible.
