Crucial M500 alternative

Recommended Posts

I used to buy Crucial M500 and M550 960GB and was quite happy with them (speed, IOPs, etc). I need more drives, similar qualities but I am lost now among various nands, controllers and manufacturing processes 16nm, 20nm....  TLC, 3D TLC, 3D MLC; Toshiba vs Crucial vs Samsung Nand and Controllers of Phison, SIlicon Motion, Marwell ... Seriously, the more I read, the less I know... I came up with some conclusion that Marwell controller and Micron MLC would be good option; anyway ...

1) What drive do you suggest as good replacement ?

2) Also - has 3D TLC reached stability of old planar MLC drives already ?

3) Any of these are good candidates ??

Mushkin Reactor 960GB, SATA (MKNSSDRE960GB) - specs --> Micron 16nm 2D MLC & SM2246EN 
ADATA Premier SP610 1TB - specs --> Micron 20nm 2D MLC & 
SM2246EM (looks same as above but more expensive)
ADATA Premier Pro SP920 1TB - specs --> 20nm Micron 2D MLC & Marvell 88SS9189 (price same as samsung 850 pro - pointless to buy)
Crucial MX300 1TB, SATA (CT1050MX300SSD1) - specs --> Micron 3D TLC & Marwell 88SS1074
Micron SSD 1100 1TB - specs -->  Micron 3D TLC & Marvell 88SS1074 (looks same as above but more expensive)
Toshiba OCZ TR150 - specs --> Toshiba TLC 15nm & Toshiba TC58  - (looks like old controller....)
Zotac T500 SSD 960GB --> Toshiba TLC & Phison

Thanks a lot !

PS: I need to get more than a dozen... so in a way price does matter...

What exactly do you expect from your SSD's? If it's just typical desktop use, then anything should work. Honestly along budget SSDs, buy whatever's cheapest from the major name brands. 3D TLC does seem to be the way to go, and it's finally proliferating among other NAND makers besides Samsung, so there's plenty of choices.

Stick with the brands that have their own fabs. Samsung, Crucial/Micron, Toshiba/OCZ.

We do have an embargo drop on an SSD next week that you may find interesting.

WD recently announced 4-bits-per-cell 3D NAND. Not sure what we'll call it - QLC? 4LC?

They didn't mention when product will ship, so 2018 at the earliest. Probably not helpful for your needs, but with 3D QLC coming, I expect 3D TLC is stable today.

No it's not desktop. Workstation mobo, dual cpu, each SSD disk is hosting one vmware guest (attached to several sas hba). Server is on 24/7 but usage of SSDs is low actually... I know that any of above SSDs would survive (even ocz vertex was used for 4 years of virtualization and health is 100%; but let's consider something newer than sandforce lol). 

So back to original question; what is decent alternative to e.g. Samsung 850 pro or EVO or good old MLCs ?? Does Crucial MX300 TLC has decent performance ? I see benchmarks are way below Samsung EVO; which is weird....

If your actual disk I/O requires are low then pretty much anything should work, including the MX300.

850 EVO actually has near best in class performance as Samsung has a significant headstart on both 3D NAND as well as TLC vs. their competitors, the 850 Pro is ahead of it (perhaps near the very top of SATA SSDs for consumer use), but it smells like either of those might be a waste of money for your use.
