Can I just add that I have ordered me a 128gb Crucial M225 and am a little concerned as to the speeds compared to my raid0 Samsung F1's.
I have ran HD Tune on my raid0 and get a max & min transfer rate of 185MB/sec and 79MB/sec (average 136MB/sec) with 11.9ms access time.
What concerns me is these SSD's read at 250MB/sec which is not that much higher than 185MB/sec.
Am I missing something?
Run Crystal mark, or anything that will give you results for random small file writes, 512kb or 4kb random read and writes.
If you run either on your sammy raid you'll probably see maybe 1-1.5mb/s random 4kb reads, and between 1-2mb on the random writes.
This is where SSD's excel, my hitachi 640gb's in raid 0(2 platter ones, the b series which are quite a bit faster than the earlier ones) would get numbers like I posted, my 2x64gb Crucial raid gets 30mb/s read and write in the random numbers, and thats largely because I have problems with the reads which should realistically be about 40-45mb/s.
But thats not as important as some make out, ssd's absolutely without question destroy normal hdd's in small file read and writes and they are important just not quite as important as many make out. The intel offers next to no real world improvement despite higher performance in the 4kb files, but lower elsewhere, clearly its not as important as people think.
I/o's is a lot of the situation, if you've ever say been unrar'ing a large file, while trying to load a game and you bring up Firefox and it just hangs for a while as the hdd's chung a long sounding like they are plotting your death. Thats the key thing, I/O's, when you do the same with an SSD the hanging won't be there, you won't get bogged down and everything is smoother.
Sequential read's are almost completely pointless on ssd's as unless you use them for business(ie you actually make money using photoshop or editing video, you'll be smart to download onto a mechanical hdd and store data on them aswell, so you'll actually very very rarely require the high sequential speeds. Install several games, and load them will be a mix of many types of reads but almost never pure top read/writes being done.
