First Look: OCZ Vertex SSD

The OCZ Vertex Series SSD introduces a new controller to help deliver the manufacturer-rated bandwidth speeds. On the outside, this 120GB SSD (model OCZSSD2-1VTX120G) looks like all of the other Solid State Drive products OCZ offers in their current product family.

When it comes to the appearance of notebook drives, it must be understood that the product you're looking at will be hidden away from plain view once installed. Keeping in mind that this product is solid state, and therefore offers no amount of noticeable physical activity, it takes some special attention to presentation in order to help keep the consumer feeling comfortable with their premium purchase. Unlike the Hard Disk Drive (HDD) storage products, SSD's are practically impervious to impact damage and do not require special vibration dampening or shock-proof enclosures. OCZ utilizes a metal enclosure for the Vertex series, which fastens with four small counter-sunk screws on the underside.

Standard 2.5" drive bay mounting points are pre-drilled and threaded into the Vertex SSD, which allows for quick upgrade or addition into any existing notebook or desktop system. The mounting positions matched up to the drive bracket on my laptop, and after only a few minutes of drive cloning I was quickly loading Windows XP.

Unlike desktop computers which utilize a SATA cable system to connect drive to motherboard, nearly all notebooks allow the 2.5" drive to simply slide directly into a connection bay within the system. In addition to notebooks and desktop computer usage, this OCZ Vertex Solid State Drive can be utilized for mission-critical backups or high-abuse data systems. One unfortunate omission from the Vertex series was the integrated High-Speed USB 2.0 Mini-B seen on the Core v2 SSD.

Now that you're acquainted with the basic exterior features of the Vertex SSD, it's time to peek inside the OCZSSD2-1VTX120G enclosure and inspect the internal components...

I'm always wary of Mbps(bits) and MB(bytes), too many people use them interchangably. The Ads on the same page for this product say "250MB" not bits, so what is the Atto 249 MBps maximum read bandwidth??? bizarre?

Anthony, typically Mbps (Megabits) refers to a transfer speed whereas MBs refer to a capacity. Whether ignorant people use them interchangeably or not, using this guideline you should always be able to figure out which it is. :)

I'm not exactly clear which side of the argument you're on here, Marko. Read up on the specifications for any SSD product, and you'll see their bandwidth speed represented as MB/s.

MB when used in advertised capacity is not Megabytes, it's Million Bytes. Bytes or Bits will be denoted by B or b respectively. When the vendor advertise 250MB, it means 250 Million Bytes which is approx to 244.14 Mega Bytes. This 244.14 is RAW Megabytes and have not included partitioning and other possible overhead used in the system which may yield lower capacity than 244.14 Megabytes.

When used on the bandwidth, make sure you fully understand what the bandwidth measures. In different network or cable setup, the bandwidth could be shared and a single device do not usually get that kind of bandwidth on average. On network, typically vendors means Megabytes when they denote MB unless otherwise denoted using fineprints, but the usual price is using Megabits which looks a lot better on paper.

# RAID-0 Setuptypoknig 2010-05-10 09:52
How exactly did you have your RAID-0 setup during this test? For instance, were you using the Intel Matrix Storage Manager or some other method?

# Intel ICH10Olin Coles 2010-05-10 15:11
RAID-0 was built using the motherboard's Intel ICH10 controller.

What stripe size was used in the RAID 0 setup and why?

# 128KB Stripe SizeOlin Coles 2010-05-12 08:49
This articles used a 128KB stripe size, which is the largest the Intel ICH10 controller allows for RAID-0 sets.

# Benchmarking A Bigger RAID 0 Arraytypoknig 2010-06-08 22:06
Hi, I have been running the same benchmarks you ran on my RAID 0 array which has 3 120GB OCZ Vertex drives compared to the 2 used in this benchmark. My results have not even been close to what I thought I would be getting after reading this review. I have posted some info about my results here:

##overclock.net/benchmarking-software-discussion/750979-benchmarking-3-120gb-ocz-vertex-ssds.html

Maybe you can take a look at my stuff and tell me why my linear read in Everest does not produce a flat line like yours (I realize I used 512MB block size, but the 1MB block size produced identical results), and why my numbers are so much lower when they should be higher. I have also ran the benchmarks without an OS (or any data) on the array at all, and the results are very similar. Any thoughts?

# Partition alignmentOlin Coles 2010-06-14 19:43
I'm betting that our results are higher because of drive conditioning: partition alignment, diskpart clean all, secure erase, etc. Since TRIM doesn't always pass through to RAID arrays, used drives will produce lower performance results.

# sanitary erasetypoknig 2010-11-27 21:23
I have had this problem fixed for quite some time now. If you go to the link I provided in my last comment you will see that using sanitary erase did trick for me... so as you said, "drive conditioning" was my problem. To keep my drives as clean as possible I use the "Wipe Free Space" feature of CCleaner. Does the same thing as wiper.exe but it works when drives are in RAID (unlike wiper.exe).

# flash, not dramscott 2010-12-02 15:43
Samsung K9HCG08U1M-PCB00 is flash memory, not DRAM... this is why we call it an SSD

# 4-drive RAID 0Remo 2010-12-23 08:42
Mr Coles, do you have any idea how would a 4 SSD in RAID-0 perform? Would you use it as the boot drive in a windows 7 system?

# RE: 4-drive RAID 0Olin Coles 2010-12-23 08:44
You should look into the OCZ RevoDrive 2 PCI-Express SSDs, which fit four SSDs into RAID-0 on one board. Our review is here:

I definitely will look for it. But, how much gain in performance would you expect when upgrading from a 2-drive raid-0 to a 4-drive raid-0?
