Still confused about external 2bay hd enclosure.
I have a choice to buy a raid 2xhd enclosure Sil 3512 that is sata 1.5gb/s or another make that uses Sil 3132 sata 3.0gb/s using 2x wd4000kd's in raid 0 .
How much will the hd's slow down using sata 1.5gb/s ?
Supposedly the sata card can do 140MB/s .
Should I even be concerned at slowing the hd's down ?
No difference. Today's hard drives cannot even come close to using all of the bandwith of SATA 1, hell the fastest drives you can buy can barely use 10% of the theoretical bandwidth of SATA 1, let alone SATA 2.
Think about it, 1.5gb per second interface speed, the fastest drives today can only read/write at maybe 120mb per second (in bursts) sustained speed is even much lower.
SATA 2 is purely marketing hype to sell more drives.
Thanks so the 2x wd4000kd should get to 100MB/s or upto 140MB/s at most and still be in the safe zone for sataI 1.5Gb/s -> I will get it and test it if slowing them down return it to newegg and get the bit more expensive sata 3.0Gb/s one. Thanks for the help.
