Just received and installed the caddy. No wonder everyone recommends NewMode - the product is just as good as the one from HP (which costs three times more even if you count the hard drive).
The packaging was great (it was shipped overseas, was afraid it could be damaged) and my 9.5mm hard drive fits perfectly.
The only thing I needed to do was to bend the latch which holds the caddy to the laptop housing just a bit (the clearance is very narrow on the Elitebook 8530), which took literally a few seconds.
Very happy with the product, would recommend it to anyone who needs more storage space on their laptop!
