An SSD State of the Union Update

I'm very pleased with the level of acceptance of SSDs today. When the X25-M first hit the market and even for the year that followed, any positive SSD recommendation was followed by a discussion of how many VelociRaptors you could RAID together for the same price as one SSD. Now we have an entire category of notebooks that come standard with some degree of solid state storage. End users are much more accepting of SSDs in general, aided by the fact that prices have finally dropped very close to the magical $1/GB marker (a boundary I expect us to finally cross by the end of 2012).

Today's SSDs are not only more prevalent than those we were reviewing just a couple of years ago, they're also a lot better. While the first SSDs still had difficulties competing with mechanical storage for sequential transfers, modern SSDs are several times faster even in the most HDD-friendly workloads. The implementation of technologies such as TRIM helps ensure the performance degradation issues of the very first drives are less likely to be encountered by anyone with a normal client workload.

Although it helped shape the client SSD business, Intel's drives are no longer the only option for performance and reliability. There are good, reliable SSDs from companies like Micron and Samsung that can easily hang with their Intel competitors. And if you're willing to live on the bleeding edge for the promise of the absolute best performance, there's always SandForce.

The client SSD space may not be mature, but I'm happy with the current state of things. With the exception of the ultra low price points, if you want an SSD, there's a solution on the market for you today.

Going forward, I'm not expecting a ton of change in the near term. Intel's Cherryville SSD has been delayed. This is the long awaited SandForce based drive from Intel. I suspect the delay has to do with Intel working through bugs in SandForce's firmware, but its efforts should hopefully make the platform more robust (although it remains to be seen if any of Intel's efforts are ported back into the general SF codebase).

In the first half of next year we'll see the first 20nm IMFT NAND shipping in client SSDs. The smaller transistor geometry will eventually pave the way for cheaper drives, although I wouldn't expect an immediate drop in prices. At the very least we'll see firmware updates enabling 20nm NAND support, although we may see the introduction of some new controllers as well. We're going to be pretty limited in terms of performance gains until ONFI 3.0 based controllers/NAND show up in early 2013. I expect the next 12 months to be more about driving enterprise SSDs and bringing down the cost of consumer drives.

The Topic At Hand: OCZ's Octane

Now for the reason we're all here today. Earlier this year OCZ acquired Indilinx, one of the first SSD controller makers to really make a splash in the enthusiast community. Ever since OCZ entered the SSD business it wanted to guarantee its independence by securing exclusive rights to a controller. OCZ initially did so by buying up all available inventory, first of Indilinx controllers, then of SandForce controllers. That strategy would only work for a (relatively) short period of time as the controller vendors sought to expand their market by selling chips to OCZ's competitors. A few slip ups on the roadmap and Indilinx was ripe for acquisition. OCZ stepped up to the plate and sealed the deal. Several months later, OCZ debuted its first drive based on an unreleased, exclusive Indilinx design: Octane.

Although Octane didn't set any performance records, it was competitive. Performance was definitely current gen, giving OCZ an in-house alternative to SandForce. There was just one issue: OCZ only sent out 512GB Octane review samples. SSDs get a good amount of their performance by executing reads/writes in parallel across multiple NAND devices. Higher capacities have more devices to read/write in parallel, and thus generally deliver the best performance. The greatest sales volume is of the lower capacity models - they're cheaper to own and NAND prices are falling quickly enough that investing in a 512GB drive rarely makes financial sense.

MSRP TBD $879.99 $369.99 $199.99

OCZ finally sent out a 128GB Octane, which I promptly put through our standard test suite.

The drive still uses sixteen IMFT synchronous NAND devices. In this case each package features 64Gb (8GB) of 25nm MLC NAND on a single die. You may remember from our original review of the 512GB Octane that the Indilinx Everest controller supports 8-channels, but pipelining read/write requests to multiple devices per channel is supported.


Look ma, no muxes!

Gone from the Octane's PCB are the TI muxes that we found on the 512GB version. With the only difference between these drives being their capacity, it's likely that the muxes were used to switch between NAND die/packages. The 512GB version has 4x the number of NAND die than the 128GB version, and it's possible that the Everest controller is only capable of directly communicating with 16 or 32 die on its own. An external mux per channel would allow OCZ to scale capacities much further.

Other than the absent muxes and a change in PCB color, the 128GB Octane is no different than the original 512GB drive we reviewed. The drive does ship with a newer firmware revision:

The updated firmware doesn't do much for performance, although it does apparently fix a number of bugs that existed in the previous version. I haven't seen any mass reports of significant issues with the Octane, although it is still pretty new. Let's hope the trend continues.

    My desktop (i7-920 based, Win7 64bit) currently have a 160GB Intel G2 as a boot drive, but my data drive is currently an older 500GB Seagate.

    Workload: Primarily editing images in Lightroom, etc. (compressed RAW files from a Nikon D700 currently).

    I would like to replace the Seagate with a 256GB SSD, but which one would be recommended for such a workload?

    Standard recommendations are:

    Intel 320
    Crucial M4
    Samsung 830

    All are known for high dependability. Last two use sata III controllers, which you do not currently have on your system, but would become faster when you eventually upgrade your system. (And will therefore remain competitive longer.)

    Thanks.

    I was thinking along those lines and not the Sandforce based as I'm generally working with compressed data.

    And true, I don't have sata III controllers, but I don't think my system is worth upgrading just yet :)

    I have a similar system (i930) and currently have a OCZ Max IOPs 120gb for my boot drive, and an OCZ Vertex 3 120gb as my game drive (along with a 600gb Velociraptor for data).

    When I first got the MAX IOPs drive, I had occasional issues with the drive disappearing (would need a reboot), but with the firmware updates, this drive has been running for 2-3 months with no problems. I never had any problems with the Vertex 3, but I got it later and it had newer firmware.

    I think the reliability issues have been resolved with the Sandforce 2281 controller and I would not rule these out as they have come down in price.

    Even if you add an SSD for working with your large photo data, Keep the Seagate as a data back-up.

    I was avoiding the Sandforce based SSD's because they are best for data that can be compressed, my images are already compressed. Images are relatively big (spanning from 5-15MB or so), so my thinking is that I should be looking at sequential read/write performance and less on random read/write performance.

    I have no doubt though that almost no matter what SSD I choose, I will get a quite nice performance boost.

    He could also get a SATA 6GB/s controller card. Reply

    Be careful of this -- the total bandwidth of a PCI-e 1x slot is only 500 mb/s. That's less than the maximum SATA III speed, and if you hook up more than one drive you could actually cap out at less than SATA II performance for each disk.

    Maybe there are more expensive adapter cards that plug into a different PCI-e slot, but I would be inclined to only rely on motherboard connections for true SATA III speeds for the time being.

    Good review. In the last paragraph on the final page, myriad is spelled incorrectly. Reply
