Intel's New 520 Series SSD Codenamed "Cherryville"

"Cherryville", Intel's new high-end 520 Series SSD, is based on 2.5-inch SATA 6 Gb/s form-factor and comes in 60 GB, 120 GB, 160 GB, 240 GB, and 480 GB capacities (versus just 120 GB & 240 GB with the 510 Series). The drive will utilize 25 nm multi-level cell (MLC) NAND flash memory made by Intel and features support for TRIM, SMART, NCQ, and ACS-2 compliance. Intel looks to be setting up to battle the SandForce SF-22xx SSDs at each capacity level and price-point.

Initial performance information on "Cherryville" shows sequential and random access performance figures are expected to be up to 530 MB/s read, 490 MB/s write sequential performance; and 40,000 IOPS reads and 45,000 IOPS writes random performance. As with other SSD manufacturers, the performance information is expected to vary between capacities, so we'll have to take a wait-and-see approach on what the final release numbers are for each capacity. In addition, the SSD drives are rated with 1.2 million hours MTBF, can operate between 0 and 70°C, and withstand up to 2.7 G (RMS) vibration.


Intel is expected to begin production of the 520 Series SSD in the fourth quarter of 2011.

    I wouldn't mind popping that Cherryville in to see how it performs.

    I'm still waiting for their 310 series to fall on price.

    Lately, I'm getting a little impatient, and I'm very tempted by the prices of the "new" Vertex Plus, does anyone know if the Vertex Plus are any good?

    I'm waiting for Tom's or Anandtech to do a review on them.

    Newegg reviews on the Vertex Plus have not been encouraging. However, OCZ usually does well with their customer service. The prices are good, but the Kingston V+100 series seem to have similar performance numbers and price, without the reliability issues...

    can someone tell my how NCQ is implemented in SSD?

    I thought that was for HDD with spinning platter to read data then sequence them in logical order...

    Is this an Intel or a Marvell controller? That is the only useful piece of information I was hoping to get from this article :(
  • scook9
    Intel still owes us a 6 Gbps Sata 3 controller!

    one day I'll have an SSD when the newegg reviews don't look so dire for the drives that cost ~$1/GB. I don't want to spend $200-300 on a single drive.

    "the SSD drives are rated with 1.2 million hours MTBF". Are they serious? Thats like 130+ years before device fails.... yea right.

    cakster, the old Raptor Enterprise 150's were rated very high prior to failure. I lost only one of 4 after almost 24/7 gaming. Back in the day they were truly monsters.

    Intel is going to have to lighten the load and make these drives faster, other SSD's and similar storage are approaching one gig/second.

    1200000 / 8 (hours a day) / 365 days = 410 years
    Good luck with that.

    Nobody is going to live that long to prove it.
