I don't understand that statement. I've never heard of "sequential reads" or "random reads". There's only one way to access a HD, or a SSD. So I'm not sure what the person who made that statement meant, but in itself, it does not mean anything.
At the risk of sounding pedantic, that statement actually has at least some meaning: To the extent that your audio files are stored contiguously on disk, the bytes will be read sequentially and the throughput from a magnetic HD will be comparable to an SSD because the magnetic head will not have to seek from track to track. If, on the other hand, your audio files are fragmented, i.e. the bytes are not in sequence, then the advantages of the SSD will be more pronounced. Historically, the terms sequential and random access refer to the distinction between tape drives and computer memory. Tapes required seeking back and forth to find files but computer memory was able to access any location "at random" with no seeking. That's why they call it RAM (Random Access Memory). Properly speaking, a magnetic HD (MHD) is something of a hybrid -- it reads sequentially if the the bytes are on the same track but is capable of random access by moving the read heads across tracks.
There's no doubt that an SSD will boot and load programs way, way faster than an MHD, but it's certainly possible that it may not deliver as great an advantage with audio files.
FWIW, I'm about to purchase a mac mini server and dedicate it mostly for Logic. I'll probably go with MHD's to get more storage for my money, especially since I expect to leave the mini server booted up and have Logic running for long periods of time. Next time I buy a laptop, though, I'll almost certainly go for an SSD for faster boot up.
