Possible (and if so best method) to Run SSD RAID on Laptop
Posted on 2014-02-09
Hey All -
I've got a Latitude E6470 which I'm about to upgrade a bit. Below are it's current specs:
- Dell Latitude E6470
- Windows 8.1 x64
- i7-2640M CPU @2.80Ghz
- 16gb RAM (DDR3-1333 DDR3) (2 x 8gb) (E6470 supports max of 8gb per Dell's website, but after reading few posts, found that 16gb works. Have used it for few months now without issue)
- x1 128gb SSD (OCZ Vector 4) in primary drive slot
- x1 320gb 5400RPM HDD in secondary drive slot
The secondary drive slot was actually a module bay I purchased which replaced the DVD Drive. It allows you to use a 2.5" SATA drive instead.
I'm upgrading the 320gb drive soon when I thought it may be a good idea to just add another Vector 4 to it and run the two drives in RAID. I have four questions about doing this, though...
1. Can I do it in this model laptop? The BIOS surely doesn't support it as it comes stock with only 1 SATA port. Given that, would Windows 8.1 alone be able to handle the RAID.
2. Since using a module bay which replaced the DVD Drive, is it's connection still just a standard SATA connection therefore any drive attached there just as fast (I/O) as if in primary drive slot? The last thing I want to do is have the RAID degrade performance
3. Assuming above two things are good to go, would either of the two things above affect performance of the RAID and if so, how much do you think?
4. Honestly - do you think the speed difference would be worth it and very noticeable over single SSD? If not, perhaps just upgrading with a bigger and faster HDD may be best.
