Intel SSD 520 Review: Taking Back The High-End With SandForce

Features

If you thought that Intel had conceded the high-end SSD market to its competition, you were wrong. The company's new SSD 520 centers on SandForce's SF-2281 controller, incorporates top-bin IMFT NAND, and is protected by a five-year warranty.

Power Consumption: Idle And 4 KB Random (Windows 7/Mac OS X)

Idle

Because SSDs are so fast, they sit idle most of the time. It's true! In almost our almost-30-minute virus scan, the SSD was only busy for 281 seconds. As a result, idle power consumption is the most important figure to consider in a desktop environment.

Samsung's 830 does exceptionally well here. Even though it employs a beefy triple-core ARM-based controller, it consumes slightly less power than Crucial's m4 and its dual-core ARM-based Marvell controller.

The Intel SSD 520 consumes the most power (even exceeding the Vertex 3).

4 KB Random Read

Tasked with a workload, the SandForce-based drives use more power than their competition. At a queue depth of one, the 60 GB SSD 520 and Vertex 3 both consume 0.5 W more than the 256 GB m4 and 830, regardless of whether you're on a Mac or PC.

4 KB Random Write

The drives based on SandForce's controller achieve higher 4 KB random write performance than the competition, while using less power.

  • Hmmm, maybe I missed a good excuse, but I'd like to see the Octane in these tests.

    I love Intel SSD. 128GB for about $210 isn't bad. It is just hard to not chose something like a Corsair GT 120GB that cost $150 with rebate over this. I would always put a Intel SSD in a computer for novice since it is reliable.

    Nice article :)

    Just need more SSD's to compare, I'd like to see similar tests done with 120GB...180GB...256GB and several more brands. Further, as I mentioned before in the other article please list the exact model numbers and OEM specs including their 4KB IOPS; otherwise folks don't understand the results and if relying on this a purchasing will have in many cases a 4 in 5 chance of selecting the wrong SSD.

    costly but i think reliability comes at a price. These ssds are best for enterprises . If the price will be little lower then the common user can afford these and get a good reliable ssd.

    "Measuring boot time is one of the best illustrations of how an SSD benefits your computing experience." Be that as it may I find it almost irrelevant seeing as I hardly ever boot my computer, perhaps 2-3 times a month if that. Getting out of standby on my HDD is a matter of seconds.

    These prices are lower than I thought. $20-$40 extra (depending on the comparison) for peace-of-mind is not outrageous.

    We didn't have the Octane on hand in the 256 GB capacity, but we'll be sure to make that side by side comparison down the road.

    Excellent point. Price is always a fickle thing.

    thessdreviewNice Review!Thanks Les. :)

    We'll keep that mind for future reviews. However, we already list model and firmware on the test page.

    Anyone else disappointed Intel isn't producing their own high end chipset? Been waiting to upgrade my X25-M for a while now (Intel 320 isn't a big upgrade) but might just go with Samsung.
