The Crucial BX200 (480GB & 960GB) SSD Review: Crucial's First TLC NAND SSD
by Billy Tallis on November 3, 2015 9:00 AM ESTIdle Power Consumption
Many SATA drives are getting close to the limits of what our equipment can measure for power consumption. It's hard to build a meter than has sub-milliwatt accuracy and can withstand the high peak currents drawn by devices like high-performance PCIe drives. Our test rig can't measure the deepest power saving modes (DevSlp), but we can look for any red flags that the intermediate modes aren't working.
The BX200 joins the club of drives than are very poor at managing power without DevSlp support. Its active power consumption and poor efficiency are enough to exclude it from being useful for laptops, so idle power isn't as important, but it's another disapointment.
TRIM Validation
A drive that didn't correctly implement the ATA TRIM command would be very surprising to find today, but it's a quick enough check. The trimcheck tool creates and then deletes a file on the disk, and later checks if the contents of the file are still accessible. In addition to verifying that TRIM is working correctly, this test also demonstrates that, for better or worse, files that are deleted cannot be easily recovered.
Nothing about the drive is completely broken, and TRIM does indeed work.

So, apparently the first "bad" crucial SSD. Oh wait, no, the second one, remember that V4 or whatever it was, heh.hojnikb - Tuesday, November 3, 2015 - link
This is miles ahead V4, because this is usable, while V4 was not.iLovefloss - Sunday, November 8, 2015 - link
Nah, Crucial still had their M4 which quite a few issues for many people.Glock24 - Tuesday, November 3, 2015 - link
Wow, didn't expect such a product from Crucial. The only other SSD that performs worse than a mechanical disk is the Kingston SSD V300 that is still being sold.hojnikb - Tuesday, November 3, 2015 - link
V300, despite its hate, is still *much* faster than any HDD out there.Glock24 - Tuesday, November 3, 2015 - link
Maybe you got lucky, but I bought one after reading some good reviews (before the nand change fiasco hit the news) and after a while I noticed something was wrong because of the painfully slow performance. It was giving me reads close to 100MB/s and writes on the 20MB/s range, and that's sequential performance. I usually do not notice any difference in tel world performance between different SSD models, but with the V300 was very notorious. Even the HDD I had in use at the time felt faster (Spinpoint F1 1TB). So no, the V300 is not faster than any HDD.hojnikb - Tuesday, November 3, 2015 - link
that was a faulty model or issue on your end. eve the crappiest models were good for atleast 75mbs of write....Gigaplex - Tuesday, November 3, 2015 - link
And most hard drives these days can beat 75MB/s sequential write.hojnikb - Wednesday, November 4, 2015 - link
sequential speeds matter very little, its the random performace that makes ssds fast. and those are orders of magnitude better, even with v300jabber - Tuesday, November 3, 2015 - link
Yeah I use V300's exclusively in SATA II based PCs and laptops as they will push 270MBps+ all day long. No point buying 850 EVOs there. Must have bought 50+ and all of them are still going strong.
