Intel SSD 660p 1TB SSD Review - QLC Goes Mainstream

08/07/2018 - 11:41

Introduction: Flash Memory Summit 2018 is on, and it's rapidly looking like the theme of the year is 'QLC'. QLC stands for Quad Level Cell, which is a bit of a misnomer since there are actually 16 voltage levels of a QLC cell - the 'quad...

Conclusion, Pricing, and Final Thoughts

08/07/2018 - 11:39

Conclusion PROS Highly competitive cost/GB (see below). Outstanding random performance for a mainstream/budget SSD. Generous dynamic SLC cache. 5-year warranty (high for a budget product). CONS Heavy sustained workloads may saturate the cache and...

Performance Comparisons - TRIM Speed

08/07/2018 - 11:20

Thanks to the plethora of data we have at our disposal from the new suite, I can derive some additional interesting data that nobody seems to have been paying any attention to yet. Have you ever deleted a large file and then noticed your system seem to...

Performance Comparisons - Mixed Burst

08/07/2018 - 11:16

These are the Mixed Burst results introduced in the Samsung 850 EVO 4TB Review. Some tweaks have been made, namely, QD reduced to a more realistic value of 2. Read bursts have been increased to 400MB each. 'Download' speed remains unchanged.

Performance Comparisons - Client QD Weighted

08/07/2018 - 11:09

These results attempt to simplify things by focusing on what really matters - the Queue Depths that folks actually see when using these products. A dimension is eliminated from the previous charts by applying a weighted average to those results. The...

Performance Comparisons - Sequential and Random

08/07/2018 - 11:03

[inline:files/review/2018-08-07/bsw.png] [inline:files/review/2018-08-07/bsr.png] Mid-pack performance on sequential writes and reads. [inline:files/review/2018-08-07/brw.png] NAND SSDs are surprisingly fast at low QD random writes. This is for a few...

Performance Focus - Intel SSD 660p 1TB

08/07/2018 - 10:49

I'm sticking with the 'burst vs. saturated' plots here, as they do well to show both sustained performance and the more realistic (for client PC usage) burst throughputs. Random [inline:files/review/2018-08-07/sbr.png] Random looks good. Even...

PC Perspective Custom SSD Test Suite Introduction

08/07/2018 - 10:31

Back in late 2016, we implemented a radically new test methodology. I'd grown tired of making excuses for benchmarks not meshing well with some SSD controllers, and that matter was amplified significantly by recent SLC+TLC hybrid SSDs that can be...

Internals, Testing Methodology and System Setup

08/07/2018 - 10:29

Internals [inline:files/review/2018-08-07/180805-213153.jpg] Intel's QLC Flash dies store 1Tbit of data each, and that added density means fewer dies needed to store the 1TB pictured above. The controller is the Silicon Motion SM2263 launched at last...

Toshiba RC100 M.2 2242 240GB and 480GB SSD Review - Tiny NVMe

06/12/2018 - 09:50

Introduction: Budget SSDs are a tough trick to pull off. You have components, a PCB, and ultimately assembly - all things which costs money. Savings can be had when major components (flash) are sourced from within the same company, but there are several...
