External eSATA - Velociraptor 10k or 7200 laptop drive?
Posted on 2011-03-19
I have an ASUS F5GL laptop for which I have ordered an Intel X25-M 160GB SSD and looking at upgrading the DDR2 400MHz 2GB RAM to new matched pair of DDR2 2x2GB 800MHz. I understand the processor is not replaceable as they are usually soldered to the motherboard. Any comments on this setup would be appreciated.
Main question: I'm considering several options for my main data (100-200GB of 10MB jpeg files, plus mixed music/Office files). Hoping someone can tell me what the data transfer/access speeds would be in the real world for the below setups.
1. Expresscard/eSATA adapter, external eSATA enclosure, VelociRaptor 10k 600GB 32MB-cache: model WD6000HLHX.
2. Expresscard/eSATA adapter, external eSATA enclosure, 7200RPM 750GB laptop drive: model WD7500BPKT.
3. Expresscard/eSATA adapter, external eSATA enclosure, with my old laptop drive at 5400RPM and 250GB. Obviously not big enough for all my data but I'd like to know how speed compares.
4. Existing drive, Western Digital MyPassport Elite 640GB USB 2.0.
Also, the last three being laptop/mobile drives would be less susceptible to damage if bumped. How much of a factor is this - how much care need be taken of a Velociraptor in an external enclosure?
