Mushkin Callisto Deluxe Conclusion

EVEREST Disk Benchmark

Many enthusiasts are familiar with the Lavalys EVEREST benchmark suite, but very few are aware of the Disk Benchmark tool available inside the program. The EVEREST Disk Benchmark performs linear read and write bandwidth tests on each drive, and can be configured to use file chunk sizes up to 1MB (which speeds up testing and minimizes jitter in the waveform). Because of the full sector-by-sector nature of linear testing, Benchmark Reviews endorses this method for testing SSD products, as detailed in our Solid State Drive Benchmark Performance Testing article. However, Hard Disk Drive products suffer a lower average bandwidth as the capacity draws linear read/write speed down into the inner-portion of the disk platter. EVEREST Disk Benchmark does not require a partition to be present for testing, so all of our benchmarks are completed prior to drive formatting.

Linear disk benchmarks are superior bandwidth speed tools in my opinion, because they scan from the first physical sector to the last. A side affect of many linear write-performance test tools is that the data is erased as it writes to every sector on the drive. Normally this isn't an issue, but it has been shown that partition table alignment will occasionally play a role in overall SSD performance (HDDs don't suffer this problem).

The high-performance storage products tested with EVEREST Disk Benchmark are connected to the Intel ICH10 controller and use a 1MB block size option. Read performance on the 60GB Mushkin Callisto Deluxe SSD measured an average 271.3 MBps with a nearly identical maximum peak of 272.6 MBps. Linear write-to tests were next...

The waveform chart below illustrates how the integrated buffer manages file transfers, and makes linear write performance appears relatively even. The results seen here are still relatively consistent compared to most other SSD products we've tested in the past. The Mushkin Callisto Deluxe solid state drive recorded an average linear write-to speed of 256.5 MBps, with a maximum performance of 260.8 MBps.

The chart below shows the average linear read and write bandwidth speeds for a cross-section of SATA storage devices tested with EVEREST:

Linear tests are an important tool for comparing bandwidth speed between storage products - although HDD products suffer performance degradation over the span of their areal storage capacity. Linear bandwidth certainly benefits the Solid State Drive, since there's very little fluctuation in transfer speed. This is because Hard Disk Drive products decline in performance as the spindle reaches the inner-most sectors on the magnetic platter, away from the fast outer edge.

In the next section I share my final thoughts on the struggle between SSD and HDD technology, as well as their new hybrid counterpart, before delivering my conclusion and final product rating.

Well thanks again Olin. Nice review. The more SSDs you test, the more crowded the competition becomes to the advantage of the end user. All is well in the SSD-verse. (PS, forgot the site, but I did see a "sale" item on an SSD, 64Gb @ $84 last week. $$ Looking better all the time.)

Good look at SSD's. Thanks for your time and effort putting this all together Olin. I'll refer back to this info when I'm ready to buy more of these drives. I'm still waiting for SSD Prices to come down a little more. I only have one of them, an OCZ Agility-2 that is seriously fast, but I can't afford to put one in the other computers yet.

Maybe SSD makers could learn a lesson from Amazon, whereby they lowered the prices of their Kindle Readers and then had the very best sales and profits that they have ever recorded in the last quarter of 2010.

I would re-check your facts about GC being as bad as defragging aN SSD drive. Yes, it will add some extra wear, but this would be nothing on the order of a full defrag. When these drives are used in a situation where TRIM is not available, then GC is the only solution available. I am very wary of their speeds when in a "dirty" state, and how a normal home desktop user would really be affected. I think cheap Slow long lasting SSD would be great(direct competitor to hard drive) simply for the Noise, power and space requirements. £/GB equality.
