They won't be able to achieve anything like 2GB/s when handling reads from swap, because they are likely to be lots of small chunks of reads - the pages being swapped in are often 4k and will be very difficult to predict, so bulk I/O will be unlikely. Same goes for writes, with the added proviso that your SSDs will have far worse small file write performance than reads, which is probably the 2GB/s headline figure. A better statistic to use is how many IOPS the disk can handle. |
