This is an old thread, but came up high in search results for Gloway.
I've just tested a Gloway Fervent SATA3 60GB SSD. It's one of the slowest SSDs I've ever tested, slower than all of the SATA2 models I've acquired. Sequential read for large transfers is the only thing it does well (450MB/sec max), but every other metric is awful, eg. sequential write speed is 70MB/sec max. It scores a mere 313 with AS-SSD. 4K read is also pretty rotten, but surprisingly for AS-SSD, 4K-64Thrd read/write are also poor.
So, yes it's cheap (about 20 UKP as of Apr/2016), but it's terrible. Spend a bit more, buy a SanDisk Ultra II instead, or if budget permits, a Samsung 850 EVO.
Budget SSDs from 5 years ago were slow, but it's shocking that misc-branded budget models today are actually worse. Lesson: if you do buy a budget model, stick with the better known brands like Samsung, SanDisk, OCZ, Toshiba and Crucial.
Thanks for the replay. I posted this two years ago and this is the first time I've signed in since and its amazing how many replies I have got since. two years later ssd prices have decreased and I have bought multiple Kingston, adata and a crucial one since(I think). however its really great that you did answer so I will no longer look at this thread wondering how crap these ssds really are!
