I saw a lot of differ storage solutions discussed on this forum so I decided to do an almost apples to apples comparison with different types of HDD and one flavor of CF/SSD. All this was done very low cost so I don't have access to the relatively expensive real SSD or very fast CF cards.
The test platform is a 1.03Ghz X30 but loaded with 1GB of SDR RAM.
Test software is Crystal DiskMark 2.1:http://crystalmark.info/software/Crysta ... dex-e.html
The Hitachi DJSA-220 is a year 2000 vintage drive. It performed pretty well for its age. When new drive is fragmented, performance is almost same as this drive.
The Hitachi ZIF drive is a pretty modern drive. Even with its power saving features, it can out perform the DJSA-220 even at the same rotational speed. The adapter is a $4.95 free S/H item off eBay.
The Fujitsu performance is obviously the best. But interesting that it is still slower than CF random read speeds.
The Kingston CF clearly beat the HDD's read speed due to very low latency. The sequential write speed met test conducted by Rob Galbraith in SLR cameras. While the read speed exceeded 20MB (133x 150KB) spec, write speed fell short and only yielded 54x.Rob Galbraith's Speed Test
Random write large and small file size fell way short of the HDDs and render the X30 painfully slow whenever it need to do sizable write tasks. This is particularly a problem when the disk is almost full. I believe this is related to the erase/reclaim operation taking the same amount of time for large or small blocks of internal memory. Blank flash cells initially starts as all ones. When card level controller writes 010 to the cells, it writes 0-blank-0. Once 0 is written into any cell, only way to return the cell to 1 is with a erase. Erase is a relatively long operation. Hence writing to an old card will become slower and slower. I am interested to see if someone had ran a benchmark on a fast card such as Sandisk Extreme and Transcend 300x both new and after 6 months of use.
Sophisticated SSDs have background erase and reclaim working without user intervention. I am interested to see if low cost SSD such as Runcore can match up to Toshiba, Sandisk (M-System) and Samsung SSDs.
The CF/IDE adapter I used is one of three no name I picked up at Akihabara in Tokyo. That little shop has ZIF adapters also. The boot drive (CF) must be formatted in NTFS in order to boot. This is one way to get around the fixed vs remobable ID bit in the CIS (card information system). A RiDATA 8GB 233X card is in use in a X40 but not available to participate in this test.
