This review is from: Shuttle DS61 V1.1 Intel H61 2 x 204Pin SO-DIMM Black Mini / Booksize Barebone System
Pros: In an age of dinky plastic computers, the sturdy steel chassis and practical design is very refreshing. The fans are quiet and all the parts fit nicely.
Plenty of USB ports (this was the main selling point for me). Liked that it had dual gigabit ethernet and serial ports too. I use this as a desktop machine mounted to a 24" monitor, but it would be great as a server in a small office too if you put in a quad-core i5+512GB SSD with a cheap NAS for backups.
Cons: No display port interface and only 2 of the USB ports are 3.0READ FULL REVIEW
This review is from: SAMSUNG 840 EVO MZ-7TE120BW 2.5" 120GB SATA III TLC Internal Solid State Drive (SSD)
Pros: fast SATA interface and fast cache.
makes pretty looking benchmark scores.
has samsung logo on it.
fast random I/O.
Cons: This drive does not hit anywhere near the claimed 410MB/s write performace, not in a burst let alone sustained. It has a big cache that masks it's true sustained speed of about 100MB/s and when used as a journal for ceph it plummets down to 50MB/s. Disgusting. This thing was built to look good in a benchmark and nothing more, it's real-world performance is sickening. A 2 GB write will average around 250MB/s, a 100MB write will hit close to 380MB/s. "sustained" may be a subjective term, but in my eye "sustained" means the rate at which I can write more than half of the disk without stopping. The 200GB Intel DC S3700 which claims 365MB/s has been reported by other people using it for ceph to hit 320MB/s which is close enough to it's advertised performace. But this is falsely advertised, if the wording was changed from "sustained write" to "max write" it wouldn't be quite as insulting. I really would have expected more from samsung. This is totally sub-par coming from a trusted name like samsung.
Other Thoughts: I'm now the proud owner of a 3 node file server cluster that can't even saturate a 1gb network connection. When BTRFS becomes stable, I will be able to get better performance in ceph with the journals running on the same disks as the data. There was another person that reported similar results with their ceph cluster and this drive, so just for a sanity check, I'm not the only one getting this type of terrible performance.READ FULL REVIEW
