There are no continous read and write speeds posted in detail view. Seems they were intentially ommited. Is it because speeds are lower than now-a-day standards, or the drive is more likely to fail? Maybe has to do with older technology & drive keeping processes?
Ratings are pretty high and users boast about speed performance though.
the only difference between the intel drives are the 330 uses 25nm nand and 335 uses the new 20nm nand. there is pretty much no speed difference between the 2. the intel 520 is a step up as intel considers it a enthusiast drive and it costs more. there is really no reason the get the 520 or 335 over the 330 if its cheaper.
