Every train has its passengers (or they stop it).

Please note that there are currently only 3 manufacturers of
hard-drives and they make/made alliances with SSD/memory
manufacturers: WesternDigital/SanDsik, Seagate/Samsung,
Toshiba/Fujitsu... And buffalo is mostly doing OEM (and doing it

On a(nother) side-note, if anyone is looking to get decent speed out
of their recent machine, do not overlook NVMe on M.2 socket:

# smartctl -d scsi -i /dev/nvme0n1 |grep -P 'Product|Capacity'
Product:              Samsung SSD 950
User Capacity:        512,110,190,592 bytes [512 GB]
# hdparm -t /dev/nvme0n1

 Timing buffered disk reads: 7368 MB in  3.00 seconds = 2455.46 MB/sec

Write speed is a tad slower but around 2GB/s, so no issues. Ah, yeah
and there is like no seek time for random IO :-)

That pleasure costed me about 5man (so 1$/GB), but hey that is 20-25
times my good 7K RPM SATA drives!

And since USB3 was mentioned, there are external pen-type SSDs that
are relatively fast. I currently use a few of SanDisk's SDCZ88-128G
for about 250MB/s R/W and 1man for 128GB.
