[gauthier]

I'm wondering if I can put those SSDs in it:

What about the one which has height of 3.73mm ?

Thanks for insight.

Not unless you intend to buy a SATA to M.2 adapter caddy for either the 2.5" primary SATA bay or ultrabay (and the necessary SATA ultrabay adapter), such as this: https://www.amazon.com/StarTech-2-5in-A ... J7U20?th=1

The extra port you're seeing in the W520 isn't M.2, it's mSATA. mSATA on the W520 uses the SATA-II standard, so your throughput will be limited to ~285 MB/s. If you need faster raw transfer speeds, then the only options are drives that live in the primaray SATA bay as it is SATA-III.

W520 is mSata, not M.2 Buy something like a Crucial MX200 mSata; available in 250 and 500 GB. And the *ugh* Samsung Evo 850 exists in 1TB mSata as well.

The Ultrabay is SATA-III as well

Thanks both for your thorough and helpful answer

I just bought a W520 with quad-core 2.5 i7 and maxed ram to upgrade my T420s, what intel ssd do you recommend to put in the msata port?

For the primary SATA bay, am I good going with this one: https://www-ssl.intel.com/content/www/u ... -spec.html

Thanks again for outstanding technical information!

Does it have to be an Intel?

My two suggestion would be SanDisk Extreme Pro or Samsung 850 Pro. I like Intel drives generally speaking, but I don't like TLC NAND.

Thanks Ajkula, I think I'll get a intel 730 (I use one with my T420s), I'm somehow leaning toward intel wrt. SSD drives and thanks for the notice about TLC which I wasn't aware of.

730 is the last Intel SSD worth owning, IMO. I've gone through a few and they were excellent.
