While I agree with Hilbert on the software thing I wonder if I am the only one who can't understand NAS manufacturers building 2.5 inch slot versions?
2.5 inch HDD drives are more expensive, are available in smaller sizes (4 TB max. atm. ?) and tend to be slower at some point.
SSDs on the other hand can't put their whole speed through the GBit interface.
And from what I saw 2.5 inch models are a bit more expensive than their 3.5 inch counterparts.
So why invest in a 2.5 inch version when you can get a 3.5 inch version? Cheap HDDs with big cache and high rpm. And you can still get an 2.5 inch drive and mount it by using some 2.5/3.5 inch adapter. SATA doesnt mind.

EDIT:
Regarding size of 2.5 inch HDDs and prices:

For home use i agree with you but on pro side i am not so on your side.
The 2.5 HDD format have risen last year for 3 reason:
- It is more energy friendly (main argument)
- The extra cost compared to 3.5 equivalent on specialised is realy low on specialised NAS's HDD.
- It permit to mix it with SSD (or use only SSD) more easily.

Now even on 3.5 Nas they bundle the 2.5 adaptator for the bay. Anyway future will be 2.5.

My old and cheap qnap model trays have holes to mount either size. Atm I have it running on a single 8Tb 3.5'' for backups and an old 128Gb SSD as system + work files.
