The Crucial BX200 (480GB & 960GB) SSD Review: Crucial's First TLC NAND SSD
by Billy Tallis on November 3, 2015 9:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so application launch times and file load times are what dominate this test. This test can be seen as the sum of all the little delays in a day's usage. Details of the Light test can be found here.
Even our Light test is enough to hit the BX200 where it hurts. The 480GB drive's average data rate is around what the first-generation SATA interface could handle.
The latency outliers are the most disturbing result so far. The Light test should not enough to bring a SSD to its knees.
Power consumption is finally getting close to normal, showing that the BX200 was able to catch a break for at least a while during this test.

I just ordered a couple more BX100's 250GBdoggface - Tuesday, November 3, 2015 - link
The MX100 was just brilliant, an easy recommendation.The BX100 has been my go to value SSD, that l I recommended to many friends. The bx200 is garbage which costs more? And is about as bad as a HDD. What the hell crucial. What the hell.Luke212 - Tuesday, November 3, 2015 - link
BX100 and MX100 were great.... how can they go backward so badly?JDG1980 - Tuesday, November 3, 2015 - link
It's looking more and more as though TLC is a big flop. It doesn't seem to provide substantial price savings, and it comes at a considerable cost in performance, durability, and reliability.For a TLC drive to be worth it, it would need to be 1/2 to 1/4 the cost per gigabyte of a MLC solution on the largest drives. It then might be acceptable for people who want moderately priced bulk storage that's cheaper than standard SSDs. But that's not close to being the case now, and it may never be.

Yeah, I still wonder if TLC is really reliable as producers advertise them.Samsung needed a "hack" to their 840 TLC series to solve data retention problems reducing life time.
We do not know if others have done the same without (obviously) telling publicly. And if 850 series has it under the hood.
I would go to MLC drives for few $ more. I feel them as more reliable and durable. And "feeling" is an important thing for me, as I put my data on them and saving few bucks may not really be an advantage when a TLC drive lives less then a MLC one.
For performance, I bet anyone to be able to discern differences in real life form an SSD to another. This are "synthetic" tests, where source of data is faster than SSD speed (RAM). For whatever real usage, anything comes from sources that are slower (HDD, network, optical disks). Load times into RAM is limited, as you don't usually load GB and GB into it but during a benchmark.
What it really matters is reliability, durability and price. TLC fails to make me comfortable with the first two criteria. Which, for me, are the most important ones.

Yeah it seems like you really need to go to 3D NAND to get decent TLC -- the 850 EVO's have so far been pretty much great. That significantly larger feature size really helps the TLC out.Beaver M. - Wednesday, November 4, 2015 - link
No wonder I have been skipping reviews of new SATA SSDs for a few years now. Nothing can touch the Samsung ones, and thats sad.ghanz - Wednesday, November 4, 2015 - link
Review request: Please do a review of Sandisk Plus, their current lowest tier SSDs available in 120gb and 240gb capacities.Will be interesting to see how those compares to the BX100 and BX200 in similar capacities.

I must buy another BX100 until the stocks will dry...
