OWC Thunderbay 4 mini Thunderbolt 2 Enclosure Review – 2TB SSD Storage at 1340 MB/s

 OWC THUNDERBAY 2 PERFORMANCE TESTING

For testing today, we are using an Apple Mac Mini which contains dual ThunderBolt 2 ports, an Apple MacBook Air which contains a single ThunderBolt Port, along with our Intel Z87 Test Bench which contains an ASRock Z87 Extreme11/ac motherboard with two ThunderBolt 2 ports.  For our purposes, we are interested in testing the Thunderbay 4 mini in ThunderBolt and ThunderBolt 2 in Mac, along with ThunderBolt 2 on our Test Bench.

THUNDERBOLT 2 SPEED – APPLE MAC MINI

Using QuickBench 4.0, we first tested smaller file sizes and this result provides a great example of how top transfer speeds are reserved for larger file sizes.  Having said that, there is no reason why, if one had need, they couldn’t use The ThunderBay 4 Mini as a boot device for OSX.

Taking a look at larger file testing, ThunderBolt 2 shines as it should, with a high read transfer of 1340MB/s and a high write transfer speed of 1291MB/s.

Using ZoneBench 2.0, we can see a high transfer speed of 1157MB/s read with write performance falling just under this.

Lastly, write performance seems to drop a bit more with Disk Speed test, however, this software is great at telling us what type of video can be viewed on this SSD.

Our MBA contains a single thunderBolt port which provides for a great comparison with the newer ThunderBolt 2.  We have only included the QuickBench Extended File Size test as low 4K transfer remained the same.

Transfer speed highs of 888MB/s read and 855MB/s write are still great speeds, however not quite what we are seeing in ThunderBolt 2.

Much like above, Zonebench performance once again drops just a bit, when compared to that of Quickbench.

Why did you show not even a single picture of its interior? You call that a review? Stop kidding! Chips matter. You photograph SSD chipsets, so please reveal what is inside ThunderBay 4 Mini.

(Need I remind you: ThunderBay 4 notmini contains four count ASM1061.)

You know what…. You are absolutely right. Give me a day or two.

Thanks in advance. I appreciate TSSDR. I hope I did not offend you, by being pushy.

On the 4th sentence of the first paragraph (page1) it said “yet capable of speeds up to 1.4MB/s”, that doesnt sound right or did you mean 1.4GB/s ?

I am trying to find out whether this unit honors write barriers, which are critical to data security ( see this thread: http://markmail.org/thread/shrs46f6lixkqllw ). Without them, a sudden power outage or an unexpectedly pulled cable can easily make a RAID completely unrecoverable by mere mortals. Have you tested that?

I am sorry but we have not tested for that.

Planning on upgrading from old MacPro running Crucial SSDs to Retina iMac. Will this TB Mini accept non-OWC drives in non-RAID config.

What happens when the TB cable is not attached. Will the drives power up and idle?
