Patriot Memory's Torqx SSD Beats Intel's X25-M

When was the last time you upgraded your PC? Was it a CPU? Was it a graphics card?

As the saying goes, a chain is only as strong as its weakest link. This saying also remains true for a computer system. There's no refuting that the slowest part of a computer system is its storage system.

Up until the last year or so, everything ran on hard drives except very rare server systems that focused on performance. These specialized systems also came with stratospheric prices--well beyond the range of consumers. Solid state drives (SSDs) changed all that recently with more down-to-earth prices and exceptional performance.

Upgrading a HDD-based system to a SSD will provide instant gratification. Before you can even play a game, or use an application, the first thing that must occur is data fetching. Most of the time, the CPU wastes cycles waiting around for the hard drive to deliver the necessary data. With an SSD upgrade, you experience an immediate and noticeable impact on everything your computer does.

Despite the huge performance gains, two major things plague SSDs:

- Poor quality flash memory controller, performance
- Cost

Thankfully, Patriot Memory's new Torqx SSD addresses both--more so the former.

The new Torqx SSD utilizes the now famed Indilinx flash controller. This is a crucial distinction because up until recently, most SSDs on the market utilized the horrible JMicron JMF602 controller. This particular JMicron controller was low costing, hence manufacturers were quick to utilize it. Unfortunately, the tradeoff between cost and performance was a bad one. Not only did JMicron-based SSDs heavily degraded in performance over time, users experienced system stuttering--the controller simply could not keep up with data requests from the CPU. Because of this, some manufacturers shipped SSDs with two JMF602's in internal-RAID mode to alleviate the stuttering.

Then came Indilinx 1DX110M00 controller, which offered performance near to that of Intel's X25-M drives. Herald as the world's best desktop SSD, the Intel X25-M up until now remains largely unbeaten. However, Intel's current lineup of SSDs are quite costly. As you'll see, a current-generation Indilinx-based SSD can come close in performance, and in some cases even beat Intel's offerings.

Patriot's new Torqx 128 GB SSD utilizes the 1DX110M00 and comes with 32 MB of onboard cache. The drive also comes in 64 GB and 256 GB flavors, all utilizing Indilinx's fantastic controller. We can't but feel partly responsible for this drive. We constantly beggared Patriot to move to Indilinx  controllers.

The true test of the drive comes after several weeks of usage. Because of the way SSD drives work, they will slowly degrade in performance over time--JMicron-based drives take a huge hit. SSDs must erase a used block before it can be rewritten to again. This factor combined with wear leveling technologies are primary culprits for poor random write performance.

We decided to run the Torqx 128 GB through a week's worth of typical usage on a MacBook Pro with a 2.2 GHz Core 2 Duo notebook, 4 GB of memory. The notebook was used because notebooks are prime candidates for SSD upgrades--SSDs negate worries about vibration. The operating system in use was Mac OS X Leopard 10.5.7.

Our preliminary results:

Xbench 1.3, Random - Patriot Memory Torqx 128 GB
    - Uncached Write: 146.85 MB/sec. [256K blocks]
    - Uncached Read: 211.38 MB/sec. [256K blocks]

Clearly the Torqx does extremely well. All SSDs perform slower with 4K blocks, and our results are in line with other drives in the same class. Compared to the Intel X25-M 80 GB:

Xbench 1.3, Random - Intel X25-M 80 GB
    - Uncached Write: 73.37 MB/sec. [256K blocks]
    - Uncached Read: 219.60 MB/sec. [256K blocks]

Under random access performance, which is the most critical for SSDs, the Torqx performs exceptionally well in our preliminary tests. In fact, the Torqx gives the Intel X25-M 80 GB a run for its money under random write performance.

We have to make note here that on a Windows PC, users will see even higher numbers, for both drives. This is because OS X turns on Journaling in its file system by default. While Journaling will provide increased data security in case of a fault, performance will take a hit. According to Apple, users may see up to 10-percent better performance with Journaling disabled.

At $399, the Torqx is still at the high-end of the price spectrum. However, consider that prices have fallen greatly recently. The Torqx provides similar or better performance than the more expensive Intel X25-M series per gigabyte, making it an attractive SSD option. The 64 GB model can be had for roughly $218 while the 80 GB X25-M costs nearly $100 more.

Look for an in-depth review of the Torqx--with more detailed tests--in a future SSD roundup from Tom's Hardware.

    While I can't argue with the content, the title and the tone of this article is just spin, spin, spin. Those preliminary tests are fairly meaningless. Most SSDs fare well with big block sizes and the slow outright write performance of the Intel SSD is well known, yet it has reportedly trumped everything else in real-world tests thus far. This would appear the same Indilinx controller that's already on the market in the shape of the OCZ Vertex and has already been reviewed far less enthusiastically here: http://techreport.com/articles.x/16848. Let's see what TH think of it once they complete their full review...
