Corsair P256 2.5” (256GB)

SSD Summer Slam: 12 New 2.5" And 1.8" Drives Rounded-Up

Corsair’s P256 SSD is an excellent product that delivers high capacity and balanced performance. Corsair didn’t try anything tricky, but simply purchased Samsung’s PB22-J SSD and resold it under the Corsair brand. That's good news for enthusiasts, since Samsung's drives aren't usually available on their own at retail.

The P in the model name stands for the performance series. Drives are specified at 220 MB/s maximum read speed and up to 180 MB/s for writes. We measured up to 208 MB/s for reads and almost 180 MB/s for writes, which are great results even though the drive cannot match the performance of Idilinx-powered SSDs. Still, Corsair does well and provides huge capacity. The company also offers SSDs powered by Indilinx hardware in its Extreme Series.

The Performance Series P256 is avialable in 256GB, 128GB, and 64GB capacities. Pricing for the 256GB model starts around $650. If you can live with 128GB, then you’ll get away with a much more palatable $350. Corsair does a responsible and all-too-rare job of providing solid product information, detailing important specifications.

The P256’s I/O performance cannot keep pace with Intel or Indilinx-powered SSDs, as the Samsung drive was delevoped mainly for desktop users. As such, it’s optimized for applications and throughput. Application performance scores well and in the middle of our test bed.

With regard to power consumption, Corsair’s P256 is the real deal, topping out at a mere 0.8W. Other SSDs, such as the Cavalry, went up to 2.3W in certain tests. Corsair’s results are stellar in performance-per-watt for streaming reads (high throughput at low power consumption). It doesn’t shine as brightly in the I/O efficiency summary, but we consider this drive excellent for performance notebooks.

    shit review, the G1 is alot worse then the G2 over time/use and intel won't be giving the G1 the Trim command

    Would have been helpful to have a hard drive in there for comparison just to reflect just how far SSDs improve performance.

    Where are the comparisons at empty verses used? This is a key differentiator at the moment and you seem to have missed the point completely. Its not how well a drive performs out of the box its how far it degrades once time has taken its toll.

    There is a lot missing from this article. TBH, I wouldn't use this as a basis for making a decision on what SSD to buy.

    One of your competitors has a superb article on SSD that they published recently, that delves into new vs used performance, and a good explanation of TRIM, and why it's important.

    IMO, this article is not up to the usual THG high standard.

    Why is the Vertex doing so extremely bad in the write-test?? Just 74MB/s write?? Is that a typo and is it suposed to be 174MB/s?

    Fail, Fail, Fail.

    Once again THG resorts to lots of silly benchmarks but misses the point... I wouldn't pick a drive based on this roundup!

    Where, or where are the degradation of write performance tests... Thinking where all the Flash blocks are used and write cycles become Write-Read-Write cycles. (heading off to AnandTech again...)

    Where is the Patriot Torqx M28 SSD (128Mb cache & 10 year warranty) in this "roundup"??

    If you want a fast boot drive for "desktop usage" you'll surely want more I/O performance emphasise.

    I meant Read-Modify-Write of course!!

    It's like you guys haven't read Anand's articles on SSDs or intentionally ignoring it. SSDs with JMicron controllers are automatically crippled SSDs. At least until JMicron cleans up their shoddy work, but then they'd have to fight against a bad reputation.
