I've been googling and searching for any SSD benchmarking utilities or tools for Mac however I have not been able to find any. I only see utilities for windows such as HD Tune Pro, CrystalDiskMark and SiSoftware Sandra. If you know of or can recommend any SSD benchmarking utilities _for Mac_, please let me.

The Hitachi Deskstar 7K1000 has the second highest overall sustained transfer rates of the three drives listed. The sustained transfer rate is nipping on the heels of the WD1500AHFD in this test while the maximum transfer rate is slightly ahead and the minimum results are about 17% slower. Our first screenshot is the Hitachi drive with Automatic Acoustic Management and NCQ turned on. The second screenshot has both features turned off.
We also tested with AAM off and NCQ on with the burst rate results mirroring the first screenshot and the access time mirroring the second screenshot. This means that NCQ being turned off is what affected burst transfer rates and AAM being on increased the access times in these synthetic tests. We did not expect this as previous test results with several drives showed that AAM usually caused a performance penalty in both transfer and access time rates. In our application tests we found that enabling AAM usually did not alter the test results more than 1% and at times the scores were even or slightly better (other than the lower access times). Even though the 7K1000 drive has excellent sustained transfer rates we will soon see this does not always translate into class leading performance. Hard Disk Performance: HD Tach Click to enlarge We are also including HD Tach results for each drive. Once again the first screenshot has the 7K1000 test score with AAM and NCQ turned on while the second screenshot is with both options turned off.
Our tests with AAM turned off and NCQ on resulted in scores nearly identical to the HD Tune results indicating once again that AAM does not inflict a noticeable performance penalty on this drive. The balance of the performance results between our test samples basically mirrors those of our HD Tune scores. Friday, March 30, 2007 - We had a lengthy meeting with the Hitachi engineers this week to go over APM and AAM modes along with the firmware that is shipping on the Dell drives. I hope to have some answers next week as testing APM capabilities on a Dell based system resulted in a slightly different behavior than our test bench. I have completed the balance of testing with various AAM/NCQ on/off combinations and some additional benchmark tests. I am hoping to update the article next week. Also, I ran acoustic tests in a different manner and will have those results available.
Until, then I did find out that sitting a drive on a foam brick outside of a system and taking measurements from the top will mask some of the drives acoustic results. The majority of noise emitted from this drive comes from the bottom, not the top.;). Monday, March 26, 2007 - 'However, Hitachi has informed us they have the capability to go to 250GB per-platter designs but launched at smaller capacities to ensure their reliability rate targets were met. Considering the absolute importance of data integrity we think this was a wise move.'
This sounds like an sneaky attempt by Hitachi to raise doubt about the safety of Seagate's forthcoming 1TB drive. Where is the data to support this rather bold statement that 250GB platters designs are not as capable as 200GB designs of meeting these completely unspecified 'reliability rate targets'? What does that even mean? Can we infer that 150GB platter designs are even more reliable than 200GB designs? It's disappointing to see the review accept Hitachi's statement without question, going so far as to even applaud Hitachi for its approach without any evidence whatsoever to back it. Thursday, March 22, 2007 - While I know memory density in general isn't increasing nearly as fast as hard drive size, 32MB cache seems pretty chintzy for a top-end product.
I suppose 16MB on the 750GB drives is even worse. My first 528MB hard drive with a 512KB cache was a 1/1007 ratio (using binary cache size, and labelled drive size which would be around binary 512MB). Other drives still had as little as 128KB cache, so they could have been as little as a 1/4028 ratio, but better with smaller drives. I think anything larger than 512MB always had 512KB. A 20GB drive with 2MB cache is 1/9536 ratio.

A 100GB drive with 2MB cache is 1/47683. Then the jump to 8MB cache makes the ratio much better at 1/11920 for a 100GB drive (I'm ignoring the lower-cost models that had higher capacities, but still 2MB cache). Then it gets progressively worse as you get up to the 500GB size drives. Then we make another cache size jump, and the 160GB to 500GB models have a 16MB option, which is back to 1/9536 on a 160GB, to 1/29802 on a 500GB. The trend here being that we stick with a particular cache size as drive size increases so the ratio gets worse and worse, then we make a cache size jump which improves the ratio and it gets worse again, then we make another cache size jump again. Now we go to 750GB drives with 16MB cache. Now we are up to a 1/44703 ratio, only the 2nd worse ever, seems like time for another cache increase.
Jumping to 32MB with a 100TB drive only makes it 1/29802. Not a very significant change despite doubling the cache again, since the drive size also increased, and it'll only get worse as they increase the drive size. Even 32MB on a 750GB drive is 1/22351, only slightly better than the 16MB/500GB flagship drives when they came out, and we don't even HAVE a 32MB/750GB drive. A 512MB cache would be nice. That's still not the best ratio ever, it's still 1/1862, but that's a heck of a lot better than 1/30,000th. At the very least, they need to jump those cache chip densities a lot, or use more than one.
Even a single 512MB density chip would be 64MB, still not great but better.
