OCZ Agility 3 SSD review -
SSD Performance HD Tach 184.108.40.206
HD Tach is a physical performance hard drive test that uses a special kernel mode VXD to get maximum accuracy by bypassing the file system.
The HD Tach sequential read test is a little bit different from other benchmarks. Most benchmarks create a file on the hard drive and test within that file. The problem is that modern hard drives use a zone bit recording technique that allows different read speeds depending on where the data is located. Data on the outside of the drive is much faster than data recorded on the inside.
When we look at write performance we see 347 MB/sec in this test, and that's surely okay for this drive.
In addition to sequential read performance, HD Tach tests the drive's random access time. Random access is the true measure of seek speed. Many drives advertise sub 10 millisecond seek speeds, but seek speeds are misleading. Also again, without a physical head that moves around, the SSDs are just so fast as they have no mechanical moving parts. Here obviously, the smaller the number is, the better. In this case, 0.1 ms.
The Burst speed measured in HD Tach was 352 MB/sec by the way. Check the test result here.
OCZ is about to inject an SSD into the market that is labeled Agility 3 SSD. What's the difference in-between Agility 2 and now 3 you might ask ? Well, two primary things really, controller and NAND flash memory type. Labeled with advertised speeds of of 525 MB/sec with write speeds of 500 MB/sec this product should be really interesting for many of you.
OCZ Agility EX SSD 60GB review
Today we test the OCZ Agility EX SSD. If 100% reliability is your thing then this is the cheapest SLC based SSD with an Indilinx controller that you can think of. The OCZ Agility EX offers top notch performance and reliability, we honestly believe in the theory that the SSD could probably outlive you.
OCZ Agility SSD 120GB review
The OCZ Agility series SSD is an accumulation of all the latest breakthroughs in SSD technology, including controller design, spiffy read/write speeds, and 64MB of onboard cache, yet with this series, at a somewhat better price. See, by doing so OCZ shaves another 20 to 25% off the sales price.
