Crucial m4 trim support mac os x lion

Most of the new SSDs have functions to do garbage collection built into the controller on the drive. Go look it up on OWCs site. Built-in garbage collection is guessing at what needs to be reclaimed. No amount of clever GC algorithms can compare to a simple instruction that says "do this". I bought a Vertex2 SSD drive over 7 months ago.

Hackintosh OS X Lion Crucial M4 SSD

I don't use TRIM. I ran a speed test on the drive right after the purchase. I ran the same test on the drive just recently. The results were the same. No loss of speed. After reading things on the OWC site and on ancillary blogs maintained by their top personnel, I have lost respect for them. One has to be able to differentiate between technical competence and cleverness in self-promotion.

I for one am not going to pay someone premium prices for their ability to BS. I have no second SSD to test. Really curious whether third-party add-on does this, or OS X itself. Decreases performance. Lion supports TRIM. Third-party drives will not get it without a hack. Trim Enabler is not needed. It is a Vertex2 with SandForce.

How to Enable TRIM for Third-Party SSDs on Mac OS X

I ran some tests on the SSD right after installing it. I uninstalled Trim Enabler, or rather installed the old kext and I have no freezing issues. TRIM enabler 1. Finally I got a blog from where I be capable of in fact get useful facts regarding my study and knowledge. Please suffer with my broken down Phrases as I am functioning at getting better!

    The author of Trim Enabler has just responded, acknowledging that older versions of the program did have problems, which are fixed in the current version. It works much better now. Further thought: if a drive is managing its own garbage, it should simply ignore a TRIM command received from the O. Thus claims that enabling TRIM could harm the drive seem dubious at best. There should be a prominent Black Box Warning just like on medications where death is a possible side effect.

    Are they just parroting a myth? Well, It is purposefully context mixed, like saying that roads are dangerous. Yes, but that makes them no less vital. Or any external SSD for that matter? USB 3. Thunderbolt attached SSD drives. Firewire attached SSD drives.

    Memory, SSDs and more

    RAID drives. So, if a SandForce-based drive can see some benefit, so will any other solid-state repository you install. In those. My question, I have an iMac Lion I was confused by SSD and external hard drives. Is one better or faster or even worth using? If you would like more assistance with determining an appropriate SSD or even External Solution , you can contact our Technical Support Team at 1 , via email or Live Chat for assistance.

    Should I get the 6g or 3g owc ssd? On average what your lifetime? Thank you very much. Lifespan deals greatly with usage. See my comment linked here for a full explanation. I installed 8. The results are very poor, not what the company has promised OWC. I wonder what he debe. Muchas thanks! As already mentioned in the thread — Black Magic uses incompressible data for its test and is meant to gauge usage for high-end video production.

    However I have a problem, I could not do the correct speed tests because I could not get the program because it is costly quickbench. Thank you very much, I hope your help.

    How to Enable TRIM on Third Party SSDs in Mac OS X with trimforce

    You can provide me in download code for a temporary test? Thank you! How do I format it so that it is reset to factory settings and initial performance? Do I use Disk Utility? I am looking to totally wipe out my hard drive and re-install the OS, so you can make me erase it all. Under normal usage, that should not be the case. For wiping the drive and starting over, using Disk Utility is just fine to reformat and partition the SSD.

    If you would like more assistance at determining the cause of the slowdown, you can contact our Technical Support Team at 1 , via email or live chat for assistance in troubleshooting the issue. This is because that the secure erase would help to reset the drive to default factory setings, including the speed, just except the p cycles.

    Hi, I have a Mac Pro model 5. Is this correct? Is there any fix for this? We highly recommend the use of a SATA 2. Would I loose some data in this process? Thanks for the answers. On a SandForce-based drive, this would report lower speeds, since the Durawrite technology used in the Sandforce controller compresses data in part to achieve its speed.

    The BlackMagic test is good for a worst case scenario of write speeds. Raw video capture deals with compressible data… whereas conversion and editing of already compressed video file types is dealing with incompressible data. How can I be sure? I thought they never needed any maintenance. That should not be the case — from our testing the speeds actually increased over time. You can contact our Technical Support Team at 1 , via email , or live chat for assistance in troubleshooting. The performance have been top notch on the subjective level, also consistent using common benchmarking apps.

    As OWC claims in their website. What tool did you use to achieve that number and why? That particular number was achieved on a 2. When finding our real-world marketing numbers we run several benchmark suites on several machine configurations to determine the optimal results. I contacted Sandforce regarding to Trim or not to Trim — They gave me good insight into their process:. In flash memory, Garbage Collection GC is the process of relocating existing data, deleting stale data, and creating empty blocks for new data.

    When the OS writes a new file to the drive, it will eventually write to the previously used spaces in the table. An SSD only knows data is no longer needed when the OS tells it to write to an address that already contains data. Sandforce has a patented technology called Durawrite. Kent Smith — Sr. Director of Corporate Marketing SandForce. Please see the linked chart from SandForce. I agree with Michael. In a worst case scenario with a unrealistic test load of completely incompressible data, still seeing less than 3X and without TRIM engaged. Between this efficiency and the top tier flash we utilize, the computer is likely to be years retired before the NAND write endurance cycles is reaching compromise.

    I should add that other controllers are always well over 1. As Michael pointed out, If the SDD controller is not aware of which blocks are unused, it has less space available for reallocation during GC.
