Hope you guys are not planning on getting a shiney new Vertex 2 SSD from OCZ this Christmas I just spent the past week testing and retesting these SSD's and compairing the results to both platter based hard drives and the original Vertex from OCZ What started out as an anomoly, quickly turned into a large number of problems with these drives Here is what happened> 1. The Anomoly I wanted to test the copy and paste speed of the Vertex 2 and compare it with 2 regular hard drives from Western Digital (One was a 7200RPM Desktop drive and the other a 5400RPM Laptop drive) I copied and pasted 200MB of data in 919 files and 85 Folders from and to the same drive and timed the result in Windows 7 However, due to Windows 7's funky caching scheme, ALL of the drives finished the test in the same amount of time So then I tried it in Windows XP Here are the copy and paste times in Windows XP-SP2 > Vertex 2 = 55 seconds (Hmmm - Only 3.6 Megabytes per second) 5400RPM Laptop Drive = 54 seconds (Thats odd, the laptop drive is faster than the fastest SSD on the planet) 7200RPM Desktop Drive = 17 seconds (Now thats what I like to see) I then posted the results at OCZ's Forum and was banned for a month They said I was testing them wrong and needed to align the partitions with Windows 7, apply several tweaks and only use synthetic benchmarks in Windows 7 but not XP (Hmmmm) But I said that I got the same results with all the drives in Windows 7! They diddn't care BANNED! After a week discussing the situation with Anandtech and Maximum PC Forum members, I finally got to the bottom of what is going on Here are the problems in testing these drives> 1. Sandforce controllers hardware compress the data going to the SSD so what is a 200MB test on a NON-Compressing SSD, is only a 100MB test on a Vertex 2 2. OCZ and other SSD makers claim that their SSD's can read and write data at 275MB/sec but Maximum PC Staff says SATA 2 ports can only transfer around 240MB per sec due to the overhead involved 3. Staff members at the OCZ Forum claimed that my testing was wrong because I did not align the partition on the SSD using a Windows 7 Boot disk but... TODAY I ran the same tests again after aligning the partition with a Windows 7 disk and I even consolidated the free space with PerfectDisk v11 that is supposed to optimize SSD's Guess what? Same results! A copy and paste of the same data resulted in 51.38, 54.00 and 54.22 seconds for the "OPTIMIZED" Vertex 2 in XP-SP2 Anand himself shed some light on the situation when I recommended ONLY using Non-Compressible Data Sets when testing SSD's That way, you can compare SSD's with hardware compression and without hardware compression fairly Anand replied that INTEL SSD's use alignment agnostic controllers and would probably be the best SSD's to use with XP He says the Intel SSD's would probably handle non-compressible data the fastest of any controller type out there OCZ uses substandard Flash memory in their SSD's (The type used in thumbdrives) and they claim that "YOUR" data is not at risk due to their new Sandforce controller with Duraclass......but, If you go to NewEgg or OCZ's Forum and read the complaints for OCZ Vertex 2 drives, you will quickly see that the top 3 complaints are Drives getting bricked by doing firmware updates or drives losing all your data, or drives mysteriously going into read only mode after a reboot (Hmmm, Who should I believe, the customers or the Advertisers?) XP is THE NUMBER 1 Operating System TODAY! XP still has a greater user base that ALL Vista and Windows 7 computers combined! Nowhere in the OCZ documentation does it say that their drives are not plug and play compatible with XP But they did give me a pretty sticker that says: My SSD is faster than Your hard drive! Bwaaahahhahahhahhahhahhahahhahahaha OCZ Sandforce drives are only good for reading static (Unchanging) data They boot fast (AS fast as my 300X Compact Flash) 12 second boot on an ATOM Dualcore! but if you want to manipulate the data already on the drive or work with non-compressible data (Video editing and such) You are better off with a platter based drive as my tests have shown ANYONE using Windows XP should buy an Intel SSD or a platter based drive If you are using Windows 7, I don't care what you use because the caching scheme ruins your test results The morals of this are... NEVER USE SYNTHETIC BENCHMARKS TO TEST AN SSD! NEVER TEST WITH WINDOWS 7 NEVER USE COMPRESSIBLE DATA FOR YOUR TEST NEVER LISTEN TO THE ADVERTIZING DEPT OF ANY SSD MANUFACTURER AND DO YOUR OWN TESTS

Shame, i like OCZ 'ram'. SSDs are still too expensive. |

OCZ SSD's are OK as long as you only use it for a boot drive with data that never changes They read fast and open your app's quickly but they are not so good when you start manipulating the data on your drive As long as the data never changes, they are fine! I torture tested both a Vertex and a Vertex 2 drive without failure I did EVERYTHING that OCZ told us not to do I ran the SSD without aligning the partitions I did not apply the OCZ recommended tweaks I defragged the drives (Big No-No) I never used trim or garbage collection, etc The drives are still as good as new If you get one, just make sure you read the complaints over at OCZ forum before you try updating the firmware or start tweaking it If I really wanted to torture my SSD's, I would try OCZ's updates and tweaks! NOT!
