WD Raptor drives in external USB2 housing useful?

RichBa5tard · 14th October 2005, 11:15

As i'm very fond of my laptop, but bothered with the extremely slow & expensive laptopdrives of today, i'm considering buying an external housing with a raptor 10k drive in it.

The drives are very fast, but won't the usb2 interface be a very limitting factor? It would be a shame to buy such a drive if usb adds 5 millisec to the 5.2ms access time.

Access time is important, not throughput. It wouldn't be used for storage but compiling / editing / copying thousands of very little files.

How are you going to connect a sata drive to an usb-port ?
... can't find the housing you want to use

USB2 has worse access times than Firewire, which has A LOT worse access times than PATA/SATA
the 10k drive is known for having extremely good ACCESS times

so in short: it's a waste of money, get a very large slower drive (even 5200rpm is good

) and you are good to go!

hehe, my answer should have been more elaborate

case if
laptop_connectors like 'usb2'
then performance = 'low'
print "Bummer the laptop hasn't got a sata-port"
if
laptop_connectors like 'sata'
then performance = 'very good'
print "miep miep"
end if

yes, most confusing

there are a few laptops out there with SATA, but they are high end and quite pricy

edit: PCMCIA is nice solution,
