Hi Brian,

would it not be better to change the values
8K Sequential

100% Read, 100% Write
100% 8K

128K Sequential

100% Read, 100% Write
100% 128K

4K Random

100% Read, 100% Write
100% 4K


to 50 % read / 50% write ?

Also I wanted to ask did you get the chance to test larger Jumbo frames with MTU>1500 ?
I have tried that with MTU 4000 and got miserable stability over iSCSI.

What you see above is my personal opinion. Don't take it as the holy bible and the one-and-only truth :)

With those workloads, it is tested with 100% read or write activity, whereas the other workloads it is a ratio inside the same test.

Also, all of these tests were performed with Jumbo frames enabled on the NIC and NAS (9000).

Great info!
About the access patterns - are those IOMeter tests?
If yes, how excatly do you perform 4 thread / 4 QD tests?
4 workers with 4 outstanding IOs each?
About the 50 Gb LBA - this means you configured the IO Meter to use 100 000 000 000 blocks?
If yes - did you time limit the test?

I hope the answer to the first question is not no :)

Cheers,
SV

Not quite sure what you meant by Expansion shelves are their own volumes, not additive.

The expansion box connects to the ESATA port and you can either create a new volume or expand the current volume.

Agreed!

The DS1512+ is compatible with the following expansion units which allow for volume expansion across the physical units:
DX513
DX213
DX510

Manufacturer Spec (emphasis added):

Synology expansion units are designed for pairing with specific expansion-ready DiskStation/RackStation models to enlarge the internal volume, or form an independent volume for backup or additional storage


Desktop: Silverstone Grandia GD05, Seasonic SS-560KM PSU, MSI 880GM-E43 AM3 mATX, AMD Athlon II X4 640 CPU @ 3.4GHz, Cooler Master GeminII S CPU Cooler, Mushkin Blackline 4GB (2 x 2GB) 1600MHz, Mushkin Blackline 8GB (2 x 4GB) 1600MHz, ASUS Radeon HD 6850, Seagate 600 240GB SSD (Boot), WDC 500GB Black SATAII (Data)

Good review overall, however, is there a reason why power consumption graphs were completely left out? I went through a number of NAS drives reviewed over the year in this category and each one shows power consumption. This info was conspicuously missing here.

Thanks

Good catch. We're completely revamping our testing protocol and will be including it in new reviews soon. We'll go back and update some of these key reviews.

Should the Synology box ever die, fail to power on, boot, etc. How to recover the data? Can another unit be purchased then move the drives to the new box and all is well?

You could move the drives into another box or actually load the drives into a generic server running your favorite flavor of Linux. Synology uses standard mdadm RAID and is pretty easy to recover from.
