Sequential Read Performance
For full details of how we conduct our Iometer tests, please refer to this article.
Sequential read performance hasn't been a strength of Crucial's Marvell based SSDs and the MX200 doesn't change that.
Power efficiency isn't too good either because the performance is low, yet the power draw is quite average.

The scaling graph reveals why: the performance at QD1 and QD2 is simply terrible compared to other drives. Most drives max out the SATA 6Gbps interface at QD2 by providing over 500MB/s, but the MX200 requires QD4 before it reaches its full potential.
Sequential Write Performance
Fortunately sequential write performance is much better. The 250GB does leave a bit to be desired with its SLC cache, but compared to competing drive in the same capacity class it does well.
Power efficiency is also decent.

Again the full SLC cache shows its impact, but now the slowdown starts at QD2 already (sequential writes are faster than random, so the cache is filled quicker). The larger capacities scale well and reach their maximum throughput at QD2.

SSD market has becoming just as boring as CPU. Time for new chipste and NVMe drives which will finally deliver an actual improvement. However for clients, it doesn't really matter...even my intel G2 was good enough.JackF - Friday, May 22, 2015 - link
I continue to be happy with my 1TB Samsung EVO drive. For $359, it is/was a good value, and consistently performs high on these comparison charts.Just out of curiosity, why is the Mushkin Reactor not included on any of the comparison charts? When I was considering an upgrade, it was at the top of my list, but you never include it in the comparison charts. You gave it a Anandtech recommendation back in February?

Sounds like what Kingston did with the SSDNow series, older SSDNow drives were fast but the newer ones are ridiculously slow, so now the same with Crucial?MrSpadge - Saturday, May 23, 2015 - link
Take another look at the BX100 - that's a really good value drive and anything but slow.jabber - Saturday, May 23, 2015 - link
The Kingston SSDs are great value as they are usually the cheapest SSDs on Amazon etc. And in most cases are probably being used to upgrade SATA II equipped hardware. In which case they will push 260MBps all day long. Seen many labour for days over SSD specs and reviews when in fact the machine they want to upgrade doesn't have SATA III.der - Friday, May 22, 2015 - link
Crucial for CRUCIAL performance. Eek!eanazag - Friday, May 22, 2015 - link
In the SSD market I only see excitement in PCIe/NVMe designs. I believe there is a place for SATA drives, but the differentiation needs to innovative; i.e. beyond performance. Warranty, reliability, consistency, software tools, and RAID support are areas for differentiation.After looking at the value & mainstream performance products in the chart the Samsung Evo is a compelling product. Crucial's BX line is a price undercutting product compared to the Evo and it doesn't do that. I say this because the BX feature set is sub-par to the Evo. The MX is the Evo's direct competitor.

I do not get TRIM validation. There was never doubt that TRIM works in the sense that they LBAs contain zeroes. The question always was whether TRIMming a drive would restore degraded performance. And for some drives, it would not.Why isn't this verified any more? Or have I missed something?

Thanks so much for the review Kristian. Now I can finally compare this in Bench to others drives when making recommendations for clients.zodiacfml - Friday, May 22, 2015 - link
Price and warranty. Anyway, it is just getting more difficult to compete with Samsung which is the case and it will just get worse.
