Early TRIM Support on Indilinx Drives

As I already briefly mentioned, Indilinx has added support for the TRIM instruction in an early firmware for OCZ and Super Talent drives. OCZ calls this firmware 1.42 while Super Talent sticks with the Indilinx label: 1711. Unfortunately, the firmware caused data loss if you put your machine to sleep and has since been pulled from both OCZ and Super Talent's websites.

When it was available, the firmware did work:

SuperTalent UltraDrive GX 1711 4KB Random Write IOPS
Clean Drive 13.1 MB/s
Used Drive 6.93 MB/s
Used Drive After TRIM 12.9 MB/s

 

TRIM is triggered by two things it seems. Either deleting a file and emptying the recycle bin (to truly delete it) or formatting the drive. Simply deleting a partition doesn't TRIM the entire drive as I found out the hard way. During normal use, TRIM should deliver somewhere in the upper 90s in terms of percent of new performance.

There are significant limitations to TRIM at this point. The instruction only works in a supported OS (Windows 7 and some Linux builds) and only with supported drivers. Under Windows 7 that means you have to use a Microsoft made IDE or AHCI driver (you can't install chipset drivers from anyone else).

Unfortunately if you’re running an Intel controller in RAID mode (whether non-member RAID or not), Windows 7 loads Intel’s Matrix Storage Manager driver, which presently does not pass the TRIM command. Intel is working on a solution to this and I'd expect that it'll get fixed after the release of Intel's 34nm TRIM firmware in Q4 of this year.

    I first started reading anandtech when I got seriously interested in SSDs and honestly, you write the best SSD articles around! Thank you for all the help you gave me in deciding which SSD to buy.

    I ordered online the new G2 last week and should be getting it in a few days. I live in Greece and the re-launched G2 has been available here for about a week now.

    I am planning on replacing the HDD on my Feb 08 Macbook Pro (last refresh pre-unibody) as soon as I get it. I am just a consumer with a little bit of knowledge on tech but not a pro at all. I just thought of asking all a few questions that I have pre-drive swapping.

    1. Will TRIM be supported on macs? Any news if and when?
    2. When then new TRIM firmware is out, do I have to just install the firmware or will I need to format everything and start from fresh in order to get it to work?
    3. I have bought a 2,5'' SATA USB enclosure in order to put my G2 in there first, connect it to the laptop via the USB and install Snow Leopard from there. After I am done, I will remove the G2 from the enclosure, swap the drives and hopefully, everything will be working. Does this sound logical? I am worried about the h/w drivers to be honest.

    Thanks in advance for your help. I will post some non-scientific time results as soon as get this done. Cant wait.

    The simplest way to swap the HD on most Mac OS machines is:

    1. Connect both the old and the new drive to the machine (internally or in an external USB or FireWire case).
    2. Use Disk Utility (included in Mac OS X) to set the appropriate partitioning scheme (GUID for Intel based Macs, Apple Partition Scheme for PPC Macs) on the new drive.
    3. Partition and format the new drive.
    4. Use Carbon Copy Cloner (shareware) to clone the old drive to the new drive.
    5. Try booting off the new drive. Note that PPC Macs can't boot from USB drives, but Intel based Macs can. All PPC and Intel Macs with a built-in FireWire port can boot from a FireWire drive.
    6. If not already done, physically swap the drives to the desired locations, boot and set the preferred startup drive.

    Awesome, thanks for the help.

    I have checked Carbon Copy Cloner and it is already one of my options. Never tried it before but looked easy enough.

    I havent decided yet which way I will do it (fresh install or clone existing drive) but I will make my mind up when everything is ready!

    Thank you for reading and saying such wonderful things, I really do appreciate it :)

    1) I don't believe TRIM is presently supported in Snow Leopard. I've heard that Apple may be working on it but I don't think it's there now.

    2) From what I've seen, it should preserve your data. It's still worth backing up just in case something ridiculous happens.

    3) What you're describing should work, although if I were you I'd just swap the drives and install. Hook your old drive up via USB and pull any data you need off of that.

    Take care,

    Another fantastic article. I just wanted to draw your attention to recent reports that the majority of currently available laptops (including the MacBookPro) are unable to support transfer rates greater than SATA-150 (http://www.hardmac.com/news/2009/06/16/new-macbook...">http://www.hardmac.com/news/2009/06/16/...imited-1....

    Since most laptops can't even use the full performance of these SSD's, do you have any recommendation regarding which one would be the best bang-for-the-buck to speed up a laptop?

    Personally, I am interested in putting SSD's in a laptop not only for the speed improvements, but I'm also hoping that it reduces the amount of heat that my laptop will put out so that I can finally find a laptop that you can use comfortably on your lap!

    Incidentally, it would be really great if laptop reviewers checked to see if they could comfortably work with a laptop at full load on their lap as a standard test.

    Even on a SATA-150 interface, you're generally only going to be limiting your sequential read speed and perhaps your sequential write speed a bit. Random read/write speeds don't really go above 60MB/s so you're fine there.

    They recommendations remain the same; Intel at the top end, anything Indilinx MLC to save a bit. If anything, a SATA-150 interface makes the Intel drive look a bit better since its 80MB/s sequential write limit isn't as embarrassing :)

    Take care,

    I hope Seagate / Western Digital etc. bring even more innovation / competition in SSD's next year... and not just Enterprise products.

    And one thing I don't fully understand is why there aren't more dedicated 3.5" drives. Patriot has the adapter but what about the rest??? No money in desktops anymore???
  • Anand Lal Shimpi - Monday, August 31, 2009 - link

    OCZ is making a 3.5" Vertex drive, waiting on it for review :)

    Take care,

    Now that the good performing SSDs are half the price of last year, I'd really like to see a 2xSSD in RAID 0 article!
  • mgrmgr - Monday, August 31, 2009 - link

    I second the request for a 2xSSD RAID-0 article...with specific discussions about which applications it benefits (Photoshop?) and which ones it doesn't.

    Before October 22nd when I buy a new Win7 computer? Please. :-)
