New Latitude 5470

John,
Thanks for the confirmation....
I don't need the WWAN drive to be bootable - so that should be fine.
Also, as long as the Transcend is substantially faster than a fast USB3 Flash drive I will be happy. It will only be holding reference information - which I will only need to access intermittently but would like to access at decent read/write speeds. With the mini USB3 Flash Drive I got 90/17Mb/s R/W speeds with the H2wTest tool.
The benchmarks on this page for sequential Read/Write are much higher - so that should be good enough for me.

Cheers !!

UPDATE: Decided spend the extra and went for the 256GB instead - seems considerably faster and will ensure I dont run out of storage for a while....

 

You will probaly find that the 256GB Transcend will have better performance than the 128GB system drive. If so, there will probably be benefit in moving the swap file and hibernation file (if you use it) to the second SSD.

Most USB 3.0 flash drives have poor write speeds. If you want something reasonably fast through the USB interface then get something like this which appears to enable UASP by default, at least with Windows 10.

Thanks again John. The 256gb was approx £35 more from amazon so went for it....

 

Ok - just to confirm I received my 256gb Transcend M.2 2242 drive and fitted it to my E5470 and so far so good.

I am currently transferring 18GB of data from the supplied 128GB LiteON M.2 to the new Transcend and a bit underwhelmed with the transfer speed. It started off OK at around 120MB/s but soon dropped to 10MB/s -which seems incredibly slow?! Just finished now and it took around 26mins to transfer the 18GB - a mixture of different sized files; 140,000 files across 17000 folders....

I have also moved the Pagefile as recommended - thanks.

I can't find a way to move the Hibernate file on Windows 7 - though....

Update: I ran the UserBenchmark tool and the Transcend gives some impressive results.

But the LiteOn failed to benchmark - because the tool seems to think a RAM Cache is active??

 

I wonder if Windows thinks that the new SSD is removable (does it show on the Task Bar as a removable drive) and the write policy is set for safe removal. If you change that to best performance (and reboot) then you should find that the files transfer much, much faster. The safe removal policy means that Windows waits for confirmation that each file is written before the next one which, with small files, means a lot of time spent sending messages and little time transferring files.

The second SSD showed up on my E5570 as a removable drive and I have failed to convinced Windows that it is fixed so i would expect that the E5470 behaves the same.

Yeah, the new 256GB is showing up as removeable but it benchmarked fine.
Both of them had Write Cache enabled - so a bit puzzled.
But decided not to worry about it. Main thing is I have the storage I need and it is fast enough - so happy ...
Thanks again for all your input.
cheers!

 

Just thought I would share the following in case anyone else has the same issue in the future...

Since I installed the new Transcend, my E5470 would not shutdown properly. The screen would just go blank after a few moments but the power LED stays on until I eventually hold down the power button for several seconds. I had waited over 2 minutes on a few occasions - in case it was still processing the shutdown....
Occasionally I also got a BSOD during shutdown - but it could be possible I had selected Hibernate on those occasions.

Removing the Transcend seemed to fix the problem....

I had set the pagefile only for the D: drive, so I moved it back to the C: and removed it from the D:.
I had also set my TEMP and TMP vars to D:\Temp, so I set them back to C:\Temp as well.

After doing the above, I can now shutdown cleanly with the Transcend fitted...

 

This could well be a consequence of Windows thinking that the Transcend SSD was removable. Stupid Windows: In one place it lets you put those files on the D drive. In another place it won't use them. Remember also that Windows 10 Fast Startup uses the hibernation file so that will also have been confused.

Not sure why you guys have issues...

here - shows my E5470 booting from m.2 2242 (Transcend 512GB TS512GMTS400 m.2 2242).

2.5" SATA slot disabled (SATA-2 and everything is disabled, and you can see the boot sequence is set to "UEFI:TS512GMTS400 Partition 2" only. That was auto-added, points to EFI\Microsoft\Boot\bootmgfw.efi)

not sure why you guys have issues

BIOS 1.4.7 a07

(After going into UEFI setup and rebooting, the system waits a bit before resetting, and then the Dell logo shows up (01:00-01:10).

It normally doesn't take a long time to boot up.)
