I got an Inateck USB 3.0 2.5″ SATA III disk enclosure. I placed my OCZ SSD in there, and got the following Crystal Disk Mark results: ———————————————————————– CrystalDiskMark 5.0.2 x64 (C) 2007-2015 hiyohiyo Crystal Dew World : http://crystalmark.info/ ———————————————————————– * MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s] * KB = 1000 bytes, KiB = […]

That’s 167 MB/s sequential write—pretty cool. Since this is on Windows 7, there’s no UASP support, which should improve performance even more. Be the first to like. Like Unlike

Got it from this slick deal. It actually performs better (on the reads) than advertised (advertised as 120MB/s), and slightly better on the writes (advertised as 70 MB/s). Update Oct 19 I ran some dd tests […]
I ran these on my (8GB RAM) Sandy Bridge Core i7-2600K (not overclocked) H67 machine. I compared a newly bought USB 3.0 16 GB drive to an internal Kingston SATA and a previously purchased 8GB USB 3.0. I also compare the USB 3.0 drives to their performance with USB 2.0 port speeds. Be the first […]
I’ve been reading up on using a USB flash drive as an L2ARC for ZFS. Some reason that since the bandwidth of USB is much lower than SATA. However, others reason that since the USB flash drive has no seek time, it will speed up non-sequential reads, which is what the L2ARC is there for. […]
