ssd in T25

2017-10-06, 5:36 AM

I was looking at a review for the T25 on Notebookcheck website.  The storage section it mentioned "The 2.5-inch SATA III bay utilizes the same M.2 adapter as our original T470. It can technically accept either one 2.5-inch drive or one M.2 2242/2280 SSD depending on the adapter. The ThinkPad 25 ships with a 512 GB Samsung SM961 M.2 NVMe SSD by default and so owners are stuck with M.2 drives unless if they can somehow get their hands on a proper 2.5-inch SATA adapter."

 

Why would someone want a sata drive over m.2 or vice versa?  Is being stuck on m.2 bad?  What part number would be a "proper" adapter?

 

thanks!

Good day.

 

Personally, since I've gone to machines with PCIe SSDs, first AHCI and now NVMe, I'd never choose going back to SATA drives. ;)

 

Regarding the adapter, you might wish to poke around the FRU BOM file: 

https://download.lenovo.com/parts/ThinkPad/t25_retro_frubom_20171003.pdf to see if anything stands out.

I'd rather look in the T470 parts list https://download.lenovo.com/parts/ThinkPad/t470_frubom_20170731.pdf because no way the T25 has it, and then 00UR495 N CABLE,HDD,SSD stands out. And it looks the part, too:

Why would someone want a sata drive over m.2 or vice versa? 


because of the pricing. With sata ssds you get twice as much space for the same price with the most models.

Of course the M.2 NVMe SSDs are much faster on specs. 

 

I updated my T25 with a 1TB M.2 NVMe SSD, but also considered a 2TB sata SSD, because of pricing at the beginning.

what brand/model  SSD did you update your T25 with?  I'm looking at going to 1TB of storage.

The easiest / cheapest way to get a T25 to 1TB of storage is to add an 512GB SN520 2242 PCIe SSD. That is if you don't need (or didn't receive) the WWAN card. This way you have two SSDs, the 512GB it shipped with and the SN520 I have :) Check eBay or https://geizhals.eu/western-digital-pc-sn520-nvme-ssd-512gb-sdapmuw-512g-a1797631.html

Do you have verification of that?  The T25 shares base hardware with the T470 and the  WWAN 2242 slot  is specified to support SATA SSDs, not PCIe/NVMe.  I've had two different SATA 2242 drives in mine that work.

 

There are a few reports out there that an NVMe drive is visible in Windows, but not in BIOS, and is not bootable.  I'd not be confident that it would even be visible in Windows, and if it is, that could change with BIOS changes.

 

If you have evidence otherwise, please post a link.

Um, I have the SN520 working in my T25 for months now. I posted https://www.reddit.com/r/thinkpad/comments/agj7f4/crystaldiskmark_520_of_sn520_512gb_2242_nvme_in/ a benchmark. I am not keen on opening it up again just to snap a photo of it. What proof would you accept if my word is not enough? 

 

And yes, BIOS doesn't see it but so what, if you want to put the OS on it, you need to put the bootloader on the first disk which is an SSD too in the T25 anyways. As https://www.reddit.com/r/thinkpad/comments/83m0d2/fun_fact_t25_doesnt_have_25_sata_slot/ details it doesn't have a 2.5" bay so you can't even put a spinning rust disk in there.

Your word is sufficient ;)  Others might appreciate a snip of device or disk manager showing the drive, but I believe you :)

 

Thanks for confirming my concern about BIOS visibility and bootability.  I'm not sure everyone will agree with "so what" if they want a bootable device likely to be supported in future BIOS releases, but to each his own.  I boot Linux and some other tools on my 2242 SATA SSD - and want it bootable especially when the primary drive fails.

 

The reason I'm concerned is this:  I have a ThinkPad Yoga 370 that supports a SATA drive in the WWAN slot in the same way as your SN520 in the '25: not visible in BIOS, not bootable, but can be read and written in Windows.  Others with later 370s (mine was an early-release unit) find that the WWAN doesn't support an SSD in any way.  Perphas I'm overly concerned, but thought others should be forewarned.  I can imagine SSDs purchased to be bootable and disappointment when they aren't.

 

SATA 2242 drives will work and are "officially" supported - at least in the T470.  Of course the performance level is different.

 

Thanks for the detailed reply,

Z.
