State Of The Art SSD Options for W500? (2015)

2015-08-15, 4:51 AM

After searching for SSD solutions for the W500 and going through quite a few out of date posts, I thought it might be time to see what our options are in Summer 2015. Especially with Labor Day sales in a week. (Incidentally BestBuy has a 480GB SSD for $148 - sale price goes off on the evening of Aug 15th I think).

o So there's the SATA II connector the HD usually goes in, as well as drive caddies for the optical drive ultra-slim bay/port.

o Then there's the ExpressCard port. I think I heard the W500 only uses the v1.2 ExpressCard standard?
o The Mini PCI-e connectors; one of which is usually the caching Intel "Turbo Memory" (which incidentally, the driver doesn't seem to play well with Win7 x64)

Am I missing anything?  I've heard wildly conflicting information on W500 support for mSATA. Is there a FAQ for this?
Should I hop on that sale^ or can I get a similar-sized SSD that won't exceed the W500's abilities for cheaper?

Another user spoke highly of the Vertex 2 SSD: 

The Vertex 2 SSD is SATA II and offers "up to":

  • Up to 285 MB/s Sequential Read
  • Up to 275 MB/s Sequential Write

On the other hand, there's this lower-cost SSD:

The PNY CS1100 SSD is SATA III but offers "up to":

  • Up to 460 MB/s Sequential Reads
  • Up to 415 MB/s Sequential Writes

    The PNY looks better in bang for buck but my question is, does this PNY CS1100 offer the 300MB/s R/W speeds to match the top spec of the W500's SATA II bus?

To my knowledge, pretty much any halfway decent Sata III SSD is going to cap out the R/W on a Sata II interface. Per the spec sheet on the linked page, it gets "up to" saturation of Sata II on the lower sizes, so that "up to" 415MB/s should consistently saturate the bus... if you have anything that actually wants to write that fast. Speaking from experience with a T61 with modified BIOS (to allow for Sata II), as well as my current machine, bus saturation at Sata II or Sata III speeds is extremely uncommon under normal use; the only times I've seen it get anywhere close were large inter-drive transfers.
