The Toshiba OCZ VX500 (256GB, 512GB, 1024GB) SSD Review
by Billy Tallis on September 13, 2016 9:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.
As compared with the Heavy test, more drives are able to offer peak performance that makes them competitive. The VX500 is not only slower than Samsung's 850 EVO and Pro, but it is also slightly slower than the Phison S10-based PNY CS2211. On the other hand, the full-drive penalty doesn't look as egregious in this test and is less severe than what most TLC drives suffer.
The spread of average service time scores is narrow, so the fact that the VX500 lands near the bottom of the chart isn't saying much. The full-drive average service time ends up less than twice that of the best drive's score.
The number of latency outliers could be better in the full-drive case, but it's not a big problem. The 250GB Crucial MX200 showed that SLC caching can backfire much worse, while the VX500 simply degrades down to the level of a budget TLC SSD.
Power efficiency of the VX500 continues to be great even when it is not performing at its best.

I like their RMA... but their Vector series is such a disaster i have to RMA my drive 3 times, and they finally give me a Vector150 which has been solid... SMART reading is getting a lot worse these days, i'm using it sololy for caching now... I have their Vertex 3 and Vertex 4, those drives are quite better than the first gen Vector drives...shabby - Tuesday, September 13, 2016 - link
Will you be reviewing the intel 600p and samsung pm961(960 evo) any time soon?Ryan Smith - Tuesday, September 13, 2016 - link
Yes, we have the 600p in-house. So you will be seeing it soon.bug77 - Tuesday, September 13, 2016 - link
Looks like a pretty pointless product to me. Then again, maybe it's only meant to tick a few checkboxes so that it can be sold to OEMs.ocztaec - Thursday, September 15, 2016 - link
Hi bug77,Thank you for your feedback. We believe that there is still a market for mainstream SATA with MLC. For users that are not quite ready for NVMe VX500 will provide the long term reliability/endurance they need. Our 5 year Advanced Warranty service helps ensure mainstream users have peace of mind should there be any issues. Thank you again for your input.

For at least six months we've had the Mushkin Reactor 1TB drive for $230. How is this OCZ worth $340 today?BrokenCrayons - Tuesday, September 13, 2016 - link
It's nice to see MLC SSDs still out there, but I'm not sure the VX500 is really worth the MSRP. They're asking a lot for their 1TB model. I think the price increase isn't worth the benefits MLC offers over the plethora of much cheaper TLC drives.kfleszar - Tuesday, September 13, 2016 - link
I wish Intel 540s was included among the compared SSDs.DanNeely - Tuesday, September 13, 2016 - link
Am I missing it, or are these not in Bench yet?Billy Tallis - Tuesday, September 13, 2016 - link
They're in Bench, I just forgot to uncheck to box that keeps them hidden. We can't set the to automatically go public when the review embargo expires.
