OCZ Vertex Features

Offering your system the incredible performance of flash-based technology, 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 200MB/sec read and 160MB/sec write speeds, and featuring up to 64MB onboard cache. OCZ continues to place solid state technology within reach of the average consumer, and delivers on the promise of SSDs as an alternative to traditional hard drives in consumer targeted mobile applications.

Perfect for notebooks and desktops alike, the Vertex Series is ideal for energy-efficient mobile computing to extend battery life, increase 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. With fast access and seek times combined with excellent reliability, the OCZ Vertex Series SSDs are the answer for consumers demanding this latest storage technology.

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. Vertex series SSD drives are available in ample storage capacities of 30GB, 60GB, 120GB, and 250GB.

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?

# El Presidente'Marko 2010-11-27 01:09
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.

# DKSGDKSG 2012-04-18 00:41
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).

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:

# RE: RE: 4-drive RAID 0Remo 2010-12-23 08:57
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?
