Cavalry Storage CASD Pelican Elite 2.5” SSD (32GB)

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

The CASD Pelican Elite SSD by Cavalry storage is the only product in this roundup based on a JMicron JMF602, which is probably the main reason for the device’s 115 MB/s interface bandwidth limit. In terms of real throughput, it reached a maxiomum 84 MB/s read and less than 50 MB/s on writes with minimum throughput way below these numbers.

Official performance numbers on the Cavalry Web site are entirely different. The firm talks about 250 MB/s read and 200 MB/s sequential write throughput, and 130/95 MB/s random read/write. These are obviously two different worlds. The site mentions 64GB, 128GB, and 256GB capacities, but we received a 32GB drive, hence we can only say the results apply to our particular capacity. Since this unit isn’t mentioned on the Cavalry site, it seems likely that higher capacity versions might perform better than this one (at least we'd hope so).

    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.
