The Mushkin Source 500GB SATA SSD Review: A Value Proposition For An Everyday PC
by Billy Tallis on November 21, 2018 10:00 AM ESTIdle Power Measurement
SATA SSDs are tested with SATA link power management disabled to measure their active idle power draw, and with it enabled for the deeper idle power consumption score and the idle wake-up latency test. Our testbed, like any ordinary desktop system, cannot trigger the deepest DevSleep idle state.
Idle power management for NVMe SSDs is far more complicated than for SATA SSDs. NVMe SSDs can support several different idle power states, and through the Autonomous Power State Transition (APST) feature the operating system can set a drive's policy for when to drop down to a lower power state. There is typically a tradeoff in that lower-power states take longer to enter and wake up from, so the choice about what power states to use may differ for desktop and notebooks.
We report two idle power measurements. Active idle is representative of a typical desktop, where none of the advanced PCIe link or NVMe power saving features are enabled and the drive is immediately ready to process new commands. The idle power consumption metric is measured with PCIe Active State Power Management L1.2 state enabled and NVMe APST enabled if supported.
The active idle power consumption of the Mushkin Source seems a bit high given the lack of external DRAM to power, but in the slumber state it is quite competitive against other SATA drives.
The Mushkin Source has a notably slow wake-up from sleep, taking more than 2.6ms when a typical time for SATA SSDs is around 1ms. The Toshiba TR200 also has a similarly long wake-up latency, and the HP S700 likely only avoids that by not having a working slumber state at all.

what are you referring to? This uses Micron and it's TLCgglaw - Saturday, November 24, 2018 - link
lol yea, are people not even reading these articles? It is using one of the best selling controllers with a great track record for a low cost one, with Micron's 64L 3D-NAND which also speaks for itself. There is nothing "risky" with this drive. Every aspect of it is very well known.Lolimaster - Thursday, November 22, 2018 - link
Till now you can still get the Samsung 860 EVO for $130.Darcey R. Epperly - Friday, November 23, 2018 - link
Good drive to speed up my Gaming Console. I don't need a high write performance.Samus - Friday, November 23, 2018 - link
Always nice to see competition, but still hard to consider this over an MX500 that sells for virtually the same price.nwarawa - Friday, November 23, 2018 - link
70MB/s seq write?! REALLY?! Makes it garbage as an upgrade. This SSD would be the bottleneck transferring from a HDD... smh.Billy Tallis - Friday, November 23, 2018 - link
Yes, but how often do you really transfer more than 150GB at a time? Even putting a full OS+apps image onto the drive probably wouldn't do that much writing in one shot. If you're only writing tens of GB at a time, this drive is still twice as fast as a hard drive.nwarawa - Friday, November 23, 2018 - link
Personally? Often. I move video folders between drives often as the projects go to cold storage. Laughable that this would be slower than my 4tb HDD at this task. But I upgrade people from HDD storage, or even smaller SSD, ALL THE TIME. MX500 or 860 EVO will image an existing 250GB so much faster.gglaw - Saturday, November 24, 2018 - link
To be fair that's a TINY niche scenario no budget drive is trying to fill. Having a performance drop after >150GB of data is transferred is something most users will encounter a couple times a year at most. Even if they are doing a full drive migration, as Billy pointed it, for most users it won't past the threshold and this is the one and only time a typical user MIGHT encounter the problem. If it adds 5 minutes to the clone time for the handful of GB after 150GB is cloned, that's the least of most users problems.The current prices make no sense either way though. It is way too close to the MX500, but the prices will have to settle into sensible patterns or these will just rot away in warehouses. I imagine the actual sell prices will end up significantly lower than MSRP. For any of my spare home rigs or office computers, the limitations of performance drop after 150GB would not bother me one bit as long as it saved enough cost to justify it. I would gladly take even a steep dropoff at 50GB if it saved several more bucks. The times I would be transferring more than this I would either A) be using my main computer or B) not sitting there waiting on the transfer/clone. I build or upgrade enough systems that anytime a workload even passes the 5 min mark, there's something else I could be working on (or sneaking in another OW match).

the price paid in the retail market , specifically Western Markets, is not indicative of the price OEM's pay or say LA/Far Eatern markets .I am noticing a bias against Chinese Brands simply based on their Chinesity?, is this how we stop them taking over the PC components world? HUAWEI e.g.
