About this deal

Note that with a 2TB SSD, the pSLC cache could be up to 500GB in size for a completely empty drive. So, if you could do sustained writes at max speed and fill that up, and then had to drain it at ~100 MB/s, it could take over 1.38 hours just to empty the pSLC to QLC. LOL. (Related: The drives take a while to recover in our Windows testing, unless you just wipe/format them.)

Official write specifications are only part of the performance picture. Most SSDs implement a write cache, which is a fast area of (usually) pseudo-SLC programmed flash that absorbs incoming data. Sustained write speeds can suffer tremendously once the workload spills outside of the cache and into the "native" TLC or QLC flash. At 2TB for your Steam stash, at least you won't have to swap games in and out as often, which signficantly helps to lessen the write burden. These days I just keep running my manual TRIMs when I do major updates and most of my SSDs never go near the 90% mark anyway before I expand or reallocate: prices below €50/TB evict quite a lot of lesser capacity drives natuerally, which interestingly have never gone near 90% remaining life in all those years. What I really want is a local shared Steam cache on my 10Gbit LAN, only one copy of every game in a houshold with nearly 10 Steam devices of various kinds.abufrejoval said:I guess the biggest question is: how do you ensure it's done steady-state processing before you turn the device off? I had ARK running once on Linux: It loaded ARK faster from a hard disk than Windows loaded it from NVMe... This drive is available in a wide range of capacities, with the largest being the 1TB model we've linked here, but if you want to go smaller for whatever reason, Sabrent also offers 256GB and 512GB options. Windows and Linux will see just a committed write, turning off the device won't loose you any data, it might just not have the opportunity to do the house-keeping and the SLC cache will remain permanently filled while the drive has to bypass it for new data resulting in HDD class write speeds. Powering off (via a hard switch) in the middle of doing anything can be bad. Most drives limit how much stuff sits in volatile storage (RAM caches) for exactly this reason. High-end drives would have a super capacitor to store power so that they can flush things from RAM to NAND in the event of a power loss. For consumer drives, it's possible, if you cycle the power in the middle of writes, to kill an SSD. Probably very unlikely, and it would depend on the model, but I know in the past I heard of this happening.

But then perhaps, you'd never trust it with your data again, when you see how badly even firmware can be written =:-O Idle power consumption is higher, but this is with the best power management features disabled, reflecting desktop rather than mobile device use. Most NVMe drives will idle with very little power usage in a laptop or other battery-dependent device, so load power consumption is technically more relevant. However, most of the time the storage will be in lower power states, such that the impact on battery life is minimal. We use the Quarch HD Programmable Power Module to gain a deeper understanding of power characteristics. Idle power consumption is an important aspect to consider, especially if you're looking for a laptop upgrade as even the best ultrabooks can have mediocre storage.As for different capacities, the MP600 Mini is available just in a 1TB config, but that's still going to be a worthy upgrade, especially if you've got one of the lower capacity options. Generally, we would expect BiCS5 to be less efficient than B47R. In our testing, these drives largely peak at 3-4W when something like the 2TB SN740 is rated for a peak of 6.3W, a substantial difference. Our 2TB SN770 reached a peak of 4.91W, which is noticeably less efficient at 1TB and 2TB. In practice, the difference probably isn’t massive as long as you have a newer controller, though - the TN436’s E19T is objectively much less efficient.
