Evo vs M500 vs M550 (mSATA)

Hey guys, I'm looking to buy a 500gb mSATA drive and the ones I am looking at right now are the Samsung Evo, Crucial M500 and Crucial M550. What I want is the one that has the lowest temperatures and uses a low amount of power. Between the Evo and M500 I know the Evo has way lower temperature and power usage but it would also cost me $40 more. I cannot seem to find any reviews about the Crucial M550 512GB mSATA and wanted to know if it was better than the M500 at achieving lower temperatures and using less power. I can get the M550 the same price as the M500 so I just wanted to know if it improves upon it in temperatures and power usage. Thanks.

I can get the drives at the following price: (Canadian $)
Samsung Evo mSATA 500GB - $309.99
Crucial M500 mSATA 480GB - $268.81
Crucial M550 mSATA 512GB - $268.99

 

I have the 1TB 840 EVO it's superb!

I would vote for the EVO mSATA because it is more likely to be frugal with the idle power as you can see from my review. I've now had the EVO running for about 6 months and it's done nothing to change my positive opinion.

However, it is possible to jump through a lot of hoops and reduce the Crucial's idle power consumption as documented here. However, I think it still struggles to match the EVO's frugality.

You also get to be able to use the Samsung Magician software with the EVO. This has some useful features.

When will Samsung be making m.2 SATA drives, dang it!

 

They do, but nothing for retail.

Plus there's the XP941 and maybe others.

However, why no M.2 EVO is one of those mysteries for which I haven't seen an explanation. Perhaps they don't see a big enough market at the moment.

So would you guys say it is worth the $40 to buy the Samsung Evo over the other ones? I really only care about temperature and power consumption. I don't care that the Evo may be faster than the other two because in real world performance I am not going to notice a difference. Does anyone have any specific temperature and power consumption benchmarks for the Crucial M550 mSATA?

 

The 840 EVO is a great SSD. I'd buy it over Crucial for sure.

 

I just bought the Samsung 840 Evo 500GB mSATA for $310 Canadian. Hope its better than my Liteon 128GB I have.

 

Oh, it is, lol.

 

If TRIM is enabled for the mSATA EVO's it will be (nobody has confirmed yet...).


See:
AnandTech | Samsung SSD 840 EVO mSATA (120GB, 250GB, 500GB & 1TB) Review

 

It is enabled, despite what they said on their initial unit that they got



I was initially worried after reading that article but I asked many guys on diff. forums and they said it was working

 

ssdlife pro stating it's enabled / supported doesn't mean anything to me.

What did the other people specifically show that made them claim it was working?

 

using that trimcheck.exe app

For some strange reason, when I run it now it's telling me error: low disk space although I have 60% free disk space

 

Yeah...


My take:

I'm sure Samsung Corp would have gotten back to Anandtech with this small 'update' if they could have.

(Which is why I'm avoiding mSATA EVOs still).

 

I'm going to purchase a ~250GB mSATA soon and was debating on either the M500 or the MyDigitalSSD BP4 (since both of these are MLC). Would the EVO be the better choice though even though it's TLC? It's going in a Yoga 2 Pro, which has no other slots for drives. I just want reliability!

 

Ok does this help to confirm that TRIM does work on the mSATA 840 EVO?





If that doesn't convince you, how else do you want me to prove that it works and Anandtech's article is not true about TRIM not working?

From Overclock Forum:

 

I've been using a 1TB EVO mSATA for about 6 months and it has caused me no worries. It also is a frugal power user when on idle (see my review) while Samsung's SSD Magician helps get everything set up.

I don't expect it to wear out before I retire it.

Such checks as I have done on my EVO mSATA show it is working fine. When I checked the speed recently it was still in the same range as when new (but I haven't been trying to kill the SSD in the way that Anandtech does).

Im running dual Samsung 840Evo 250GB mSata in raid 0 on my laptop with intel RTS and the trim command seems to be working,

 

TRIM is not a box to be checked off (for me).

It signifies that PEFORMANCE is restored, which Anandtech's tests shows it doesn't.

No worries; I could be wrong - but still, I want to bring this to the OP's attention.

For myself: I haven't bought any EVO mSATA drives because of this issue reported by Anandtech.

 

Anantech article also says

But i never saw anything later, have you seen any followup?

 

That's the issue for me: I never have seen this addressed (as the article states it will if/when Samsung replies).
