Results and impressions
First thing that we noticed upon transfer of OS to SSD is that system got more responsive compared to RAID system used before. This is result of not only higher read speeds but also because of lower access times of SDD. Boot-up time of OS was in all cases slightly faster, but not fast as it was in Intel SSD. Scanning with antivirus depends almost only on CPU speed so we tested AV scanning on configuration with fastest CPU.
Scanning with Avira on SSD was significantly faster. Similar test was reading of small and large files but for this operations CPU speed was not important. As you can see from other tests that depend on reading speed (boot-up time, game level load time and similar), SSD performed well while test with copying files from partition to partition were slower even from 3 year old Maxtor. First we thought that it was some error on our side but after we repeated test several times and got the same results every time we suspected that it was something wrong with SSD itself. This baffled us until we saw results of write speeds and its graph. As you can see from graph, until 25% of capacity is reached, speed is according to specification (around 93MB/s), but after that it started to oscillate. We can only conclude that manufacturer used faster chips for first 16 GB and for the rest of disk capacity used slower (cheaper) memory chips. Although writing speed graph looks bad it didn’t have to much influence on OS performances because, actually OS performances much more depend on read speeds. If we optimize placement of data on SSD and place OS with most used applications on end of SDD we can eliminate problem with writing speed. Since this SSD is intended to be used in notebooks, this is the scenario where this SDD shines the most. Compared to WD Scorpio 250GB that was present in our notebook, and it is considered as fast notebook HDD, problems with slower writing speed is even less noticeable.
We wanted to compare performance levels on 3 different configurations just to check if owners of older motherboards will get same performance boost as owners of newer motherboards. Test results showed that this SSD performed almost identically on all configurations and the differences were minimal.
