The SanDisk X400 1TB SSD Review
by Billy Tallis on May 6, 2016 9:00 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
Unlike on The Destroyer, the X400 can't quite keep pace with the Crucial MX200 or other MLC drives on the Heavy test, but it is still faster than the other planar TLC drives.
The average service time of the SanDisk X400 on the Heavy test is the best among planar TLC drives, but the TLC drives are all still at the bottom of the ranking by comparison.
The number of latency outliers experienced by the X400 puts it in the same class as the other planar TLC drives, while most of the MLC drives have much tighter control on latency.
As with The Destroyer, the X400 comes in third place for power consumption and overall efficiency, behind the Crucial BX100 and MX200. This is impressive given how write-intensive the Heavy test is and how the the higher power consumption of TLC flash is usually most apparent for write operations.

It uses less power than some, and is priced lower. But it seems performance is severely lacking..jabber - Friday, May 6, 2016 - link
This just shows what a fantastic budget SSD the BX100 was. Crucial were stupid to dump it.Mixal11 - Sunday, May 8, 2016 - link
Exactly, for me it's v300 for low end desktop, BX100 for laptops (hard to get over time) and Sandisk Extreme Pro or 850 Pro for high end. I avoid TLC, because of experience with Dell Samsung 841oem. Who knows if I can read data from it after year or two. TLC drives are great to reduce ssd prices.jabber - Sunday, May 8, 2016 - link
Yeah everyone moaned about the V300's back in the day but they are perfect SSDs for putting in SATA II kit as they push 285+MBps all day long...plus they are the cheapest you can buy usually. Also I have bought dozens of them and not one has yet failed. They are a solid tough little SSD. I shall be sorry when they go.jhh - Friday, May 6, 2016 - link
I wonder if they have included any of the increased endurance technology from their Smart Storage (formerly part of Smart Modular) acquisition. The idea behind the technology was that most cells didn't need full current to program, and when programmed with less than full current, that the cell would allow more write/erase cycles.Michael Bay - Friday, May 6, 2016 - link
Goddamn it, one more terabyte.Just one.

I think if I were shopping for a TLC drive I'd stick with Sandisk too. I haven't had any issues with their Ultra II's, although many people have. I have, however, had two ADATA SP550's fail (a 120GB and 240GB) one during a power failure in a laptop (BSOD) which a secure erase recovered usability of the drive, and another within an hour of installation - cloning about 100GB of data to it killed it an no longer detects by BIOS.I have 5 or so other SP550's in the field running fine though, but none of them have suffered the "abuse" of the above cases.
I have dozens of Mushkin drives out there, even ECO2's, all running incredibly well. I have a few ECO3 TLC drives in house about to go out, but I've been avoiding them because the ECO2 is still available.
On a side note, I still have 840EVO's coming in at least bi-weekly with basically unusable performance. Samsung is hell to deal with for RMA (a stark contrast to, say, OCZ that actually sends you an advanced replacement!) and nothing I can do revives performance in these drives. Secure erase, fill and trim, etc, nothing works. Even after a fresh OS install they read at half the speed they write. It's crazy, slower than a 2.5" hard disk.

Win 8.1 - STILL? -For the love of god WHY?

Switching to Windows 10 would require re-testing a lot of drives, monopolizing the testbed for a month. It'll probably happen at some point this year, but I'll need to put together a second system for it (hopefully a Skylake system with working PCIe power management).jabber - Saturday, May 7, 2016 - link
Yeah no rush, after all 85% of 10's code is...8.1.
