Currently £136 for the 480gig version on Scan.co.uk, very tempted as an upgrade for my gf`s rig, one thing i would like to know though, page 16 shows read/write speeds for various drives....were these reading taken when the drives were empty, reason for asking is i have in my own rig 2 Samsung 960`s, a 960 pro 512gb and a 960 evo 512gb, my pro which i use for os and a couple of games has 131gb free and gets 1800 seq read with As ssd, my evo which has 8 of my games on has 151gb free and gets 2100+ seq read, in both cases read/write speeds are no where near the empty drive speeds when i first in stalled them.

So i`d like to see populated test reading for the mp 300 480gb please.

ADATA XPG 8200 is still better in low cost category.

@Hilbert Hagedoorn : Are you keeping testing system up to date? If yes, it can pretty significantly affect results. Likely in negative way as newer patches for intel kind of degrade thing here and there.
I am not saying that you should be testing on system without patches, that would be unfair for audience as they would see worse performance in their systems.
I am saying that keeping all results perfectly fair with each other is quite some work for you.

I am really not seeing the point of these PCIe x2 drives if they continue to cost the same as budget x4 ones. The expensive part of an SSD is the NAND chips, so saving a couple bucks on a cheaper controller isn't going to make them cheaper.

My enthusiast side want to still get the 960 EVO at some point but my wallet says that this model is more worth it.

Also, HH, please, the copy and paste is extremely strong for the "" part of the review. You give installation instructions for a SATA 6gbps SSD, not for an NVMe SSD. >.>

Ah yes, the correct NVMe snippet is now inserted.

As to the other questions. Populated SSD testing is a good point, while I do not secure erase or format the SSD before each new benchmark run (as hey you do not do that in real life either) I do make sure the storage unit is empty. All SSDs and HDDs are prone to lose some performance once they get filled up. However keep in mind that there are more factors to consider, the biggest perf hits you see often are related to a boot drive, e.g. OS drive. Windows continuously do stuff these days and an SSD simply does need 20 minutes to recover. Also, power states have an effect on the SSD, e.g. if you proc is clocked down in desktop idle, your SSD can perform slower. I could consider loading the SSD 75%, but here again, if I would give the SSD time for trim, GC and recovery perf always has been back to normal levels in my experience.
