![]() However, when compared with the USB 3.0 external enclosures with the SSD’s, the performance difference is quite significant. I’ve been incredibly happy with my USB 3.0 HDDs overall for the last few years and I only purchase USB 3.0 HDD drives based on my performance tests a few years ago. The two external USB 3.0 HDD drives had very similar performance characteristics, and they beat their USB 2.0 counterparts performance wise significantly. The numbers he quoted didn’t match my previous testing, so he made a recommendation for a specific USB 3.0 enclosure, and I figured, for $20 it was worth testing, so I bought an extra Hornettek Panther USB 3.0 device for comparison testing along with the Vantec NexStar CX eSATA enclosure I had already selected.įor the tests, I ran a short set of tests using SQLIO that I previously blogged about on my blog post about the Powershell parser for SQLIO output. Based on this tweet, I set out to my local MicroCenter computer store to purchase a eSATA enclosure and while I was buying it, one of the sales representatives, a guy named Chris, approached me and asked what I was planning to do with the enclosure because USB 3.0 should be faster for SSD’s. However, after tweeting about the results, my friend Jose Chinchilla ( Blog | Twitter) mentioned that I should also try out eSATA because it performed significantly better in his own tests. Initially I was just testing the MassCool USB 3 enclosures that I purchased, and I was incredibly happy with the performance that I had from them. I happen to own a number of OCZ drives at home and they are one of my favorite brands personally because of the overall reliability I’ve had with them the last three years as well as the performance to cost ratio I’ve experienced. When I purchased the 240GB SSD I paid right around $1.08 per megabyte, showing how much the prices have decreased nearly 3 years later. The SSD’s used with the external enclosures listed above are:Īt the time that I bought the 120GB drive I paid close to $2.42 per megabyte for it, and at the time this was a good deal. The external enclosures being tested in these tests are as follows: Western Digital My Passport Essential 500GB USB 3.The external USB 3.0 HDD’s being tested are as follows: Specifically I tested two different USB 3 2.5” SATA enclosures, a separate eSATA 2.5” SATA external enclosure, as well as two USB 3 HDD’s that I already owned to get some performance information from each of the setups. To make this blog post something worth looking at, I ran a number of additional tests over the last few days using SQLIO and a varying configuration of drives with external enclosures. Initially the performance was impressive, and I posted a few tweets that attracted some attention and a few people requested that I blog my results. When the package from Newegg arrived, I immediately installed the SSD into one of my personal machines and then later I went about testing the performance of the USB 3 external enclosures with the older SSD’s. The cost for the MassCool enclosures was only $14.99 so I figured it would be a good way to reuse the SSD’s at the time. A few weeks ago I purchased a new OCZ Agility 3 240GB SATA III SSD from Newegg when it was on sale and at the same time I also purchased two MassCool USB 3 external enclosures to make use of the two 120GB OCZ Vertex 2 SSD’s that I would have sitting around. ![]() I recently did some drive upgrades in my personal laptops and as a result I had a couple of SSD drives sitting around that I wanted to make use of.
