poor sequential read throughput
That's the expected behaviour of this disk. Extremely fast for common tasks (booting and loading apps) and slower for less common and less performance-critical tasks. If you really need the SSD-like performance for all your tasks, buy a 500GB+ SSD, if you have the money for it.
In a number of tests, the XT is actually slower than Seagate's year-old Momentus 7200.4, a drive that costs $40 less.
That's because it's probably a $40 cheaper disk with an $80 SSD attached to it.
