It will also be interesting to see how the temperatures of the installed NVMe SSDs behave. After all, the installation space is very limited, and these SSDs tend to run quite hot.

To illustrate the respective changes, I conducted measurements without a SATA caddy (including a fan), with a caddy and fan, and finally with a caddy, fan, and a homemade aluminum passive cooler.

A Mega Fastro MS200 with 2 TB was always installed in M.2 slot #2; this tends to run very hot (especially the controller). A Samsung 970 Evo Plus reaches slightly lower but ultimately similar temperatures. A “Drive Temperature 2” doesn’t seem to exist, which is why it’s missing below.

Laufwerkstemperatur 1

The three values in the table, from left to right, are: Minimum, Maximum, and Average. The values stated are in degrees Celsius.

Laufwerkstemperatur 3

The three values in the table, from left to right, are: Minimum, Maximum, and Average. The values stated are in degrees Celsius.

Laufwerkstemperatur 4 (Probably the controller)

The three values in the table, from left to right, are: Minimum, Maximum, and Average. The values stated are in degrees Celsius.

Laufwerkstemperatur 5

The three values in the table, from left to right, are: Minimum, Maximum, and Average. The values stated are in degrees Celsius.

Laufwerkstemperatur 6

The three values in the table, from left to right, are: Minimum, Maximum, and Average. The values stated are in degrees Celsius.

Laufwerkstemperatur 7

The three values in the table, from left to right, are: Minimum, Maximum, and Average. The values stated are in degrees Celsius.

The effectiveness of the thermal pad and aluminum heat sink, in particular, cannot be denied.

Thanks to the many available 3.0 lanes, an above-average number of NVMe SSDs with full bandwidth can be used. Due to the high prices at the upper end of the capacity range, I was keen to experiment with two SSDs and, when I saw a very good offer from Mindfactory at the time of purchase, I was tempted to buy something that was quite unfamiliar to me:

Two MS200s from Mega Electronics (MS200200TTM), a South Korean manufacturer like Samsung that uses Micron or Intel NAND. These PCIe 3.0 NVMe SSDs with 2 TB capacity were repeatedly offered at bargain prices for a while, and the data sheets look good: fast DDR4 DRAM cache, high TBW, good write and read performance – everything as desired.

I’ve read quite a few comments about “Mega Fastro Kaputto,” and the 1 TB version is said to have been prone to failure – but I haven’t noticed anything unusual with my model so far.

It’s important to mention that the MS200 is double-sided and therefore doesn’t fit into every M.2 slot. You have to be careful with mobile devices or expansion cards, and this also plays a role in the compatibility of passive heat sinks. For example, only single-sided M.2 SSDs fit on the expansion card I use.

• Two MS200 with 2 TB each from Mega Electronics, on the motherboard under the passive heat sinks of the board
• Two Samsung 970 Evo Plus with 2 TB each*, on an x8 expansion card (x4x4 bifurcation*) including JEYI passive heat sinks
• One Samsung 970 Evo Plus with 500 GB*, also on the motherboard
