The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
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.
Specifications list 550MB/s read and 530MB/s write performance and ATTO results are just about exact at 555MB/s read and 528MB/s write. Having these same numbers result in the transfer of highly incompressible data will be very convincing as to the Vector’s 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. In the OCZ Vector SSD, performance results are very similar whether we test with compressible or incompressible data and, for this reason, results are displayed utilizing incompressible data.
This analysis was completed using random, or highly incompressible, data and these results are amongst the best we have seen to date. In fact, these are very similar to the Samsung 840 Pro SSD we recently reviewed.
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 because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
Lightning fast disk access times are highlighted by great performance and a Total Score above 1000 points which is what we like to see. Taking a look at the IOPS, we can see that 4k random IOPS of 92006 read and 76595 write are just under that of specs.
This AS SSD Copy Bench result is, once again, almost identical to the Samsung Pro and one of the two top results we have seen to date.
Excellent as always, Les! Can’t wait to get mine in for testing!
I am very excited about this drive! Maybe it will be my next ssd.
Geeze, SandForce is getting kicked to the curb with this one. Do you think this will send toggle NAND to the sidelines for good?
What about this V. OCZ Vector Turbo
Eh?
Les, I took a chance and bought the 512GB from your Amazon link! I hope I like this drive!
You will and thanks! Need any help at all, send me a note as you have my email! Congrats…the long wait is finally over!
Yes, I just had a feeling about this drive. Bought a few shares of OCZ yesterday as well. They are very cheap 🙂 But I am betting that this drive keeps them as a major player. And like you, I believe SSD’s are a HUGE market. And I always thought them buying Indilinx was a great idea. And this drive is the culmination of that.
Ya…shares are a pretty safe bet at this point…too bad I couldnt jump on that train.
Well, I only got 85 shares. Becasue I blew all my other $$$ on… AMD! Which I really hope makes a comeback 🙂 I am really betting that OCZ learned from their earlier mistakes. It did take awhile for this drive to appear. It is also my first 512GB drive.
I bought 350 more shares of OCZ. I am betting that this drive is going to be a BIG winner. I hope I am right.
Got the disk today. Cloned it with no issues. Seems to be working just fine. Cannot seem to find the toolbox software online. Seems to top out at the Vertex drive.
Congrats Dave!!!
Les halo! First post here. Excellent review. Well i still side with 840 pro but OCZ did some serious job here. One question do you disable LPM before testing? Any opinion on that?
LPM as in CStates? I feel a bit embarassed that I dont know the definition eheh. If it is power management, check out the results in our forums here AFTER I disabled the C States…Actually I am going to give you the whole thread as my benches were only the first!!!

LPM is SATA “Link Power Management”. Just registered btw.
Well looks like a strong boost with c states! On par with the 840pro. Well i won’t cancel my order for the sammy though!
Check this link. https://forum.crucial.com/t5/Solid-State-Drives-SSD/Solution-C300-Disk-Freeze-ups-in-Windows-7-solved-for-me/td-p/38766
It looks like an important performance factor ignored by many. Maybe a note for the optimization guide? Trust me i felt embarassed more than once from your knowledge of ssd’s! Lol I’m a gpu knowhow guy. Your name is not wikipedia after all!
Hello Les, tanks for the review! Great as aways! I would like to know what SSD do you recommend between the Samsung 840 Pro 250GB and the OCZ Vector 240GB? I don’t understand so much about technical specifications, but I wan’t the very best available on the market at this moment! I’ll buy two SSDs to use on RAID 0, because of that I can’t do the wrong choice, since I’ll spent a good amount of money on this.
Neither of these drives could be he wrong choice and I haven’t settled on a favorite just yet as they are so close in performance and both have five year warranties. Either is the right pick for your needs.
Hi Les! Just bought two of those for RAID0! I’m in love with this SSDs ehe but I’m having a little problem. The write-back cache on IRST can’t be enabled =( Do you have any ideas to help me to enable that? The IRST version is 11.7.0.1013. One more thing: can I enable the TRIM function with this version of IRST? (if yes, how can I do that?)Thanks a lot!
Hello Les, it is very good review but what about the DRAM Controller and two of the DDR3 256MB DRAM. Cache? how it it work? what is the advantage of this function?
How good is the IOPs with SATA 3Gb/s? That would be good to know for people that have older laptops and want to buy the Vector for their old laptop but want to eventually upgrade their laptops.
Pretty much any SATA III spec’d SSD will saturate the SATA II bus. Real world performance will float around 230MB/s . If you’re on a SATA II limited system, you can either save $ by buying a lower end SSD like an Agility 3 or know that with a 5 year warranty this SSD will be waiting with a performance jump when migrated to a newer system.
Its been 3 months, the Samsung Pro can be had for 100.00USD less than the Vector in the 512gb flavor. No contest Samsung every time. If both prices were equal, I would probably have a harder time deciding.
