Product Specifications

Product Description:	IronKey D500S is an essential pillar to meeting Data Loss Protection (DLP) best practices with the toughest military-grade security for compliance with data encryption laws and regulations such as CMMC, SOC2, NIS2, FISMA, GDPR, PIPEDA, HIPAA, HITECH, GLBA, SOX and CCPA, along with TAA. D500S offers more features than any other drive in its class, making it an industry-leading security solution for high-value, confidential data protection. D500S self-tests upon bootup and over-temperature or voltage conditions will lead to drive shutdown. For added peace of mind, D500S incorporates digitally-signed firmware, making it immune to BadUSB malware. Brute force password attack protection is always on to guard against password guessing and will ultimately crypto-erase the drive if invalid password retries are exceeded. It offers a Multi-Password option to access data, which supports up to three passwords: Admin, User and One-Time Recovery. Admin can reset a User password and also enable a One-Time Recovery password to restore access if the User password is forgotten. D500S supports traditional Complex password or Passphrase mode. Passphrases can be from 10–128 characters long. D500S includes an industry-first Dual Hidden Partition option where Admin can create two custom-sized secure partitions for Admin and User, thereby allowing for a Hidden File Store that can be used to provision files to the User partition as needed. When using untrusted systems or sharing the drive, the Hidden File Stores keep their data secure and invisible unless properly accessed. A managed version (D500SM) that allows central management of drive access and usage across a fleet of drives, is available upon request. Please contact us for more details.

First Class all round!

I don't use Mr Memory frequently but have bought from them for many years when upgrading my (and extended friends and family's) various computers or replacing hard drives. I have never had cause to contact them outside of the normal process because a) everything has always been spot on and b) I haven't been a numpty before and ordered the wrong thing! So the most recent transaction with them has been a wholly enjoyable experience and totally different from any other contact I have had with any other company.
I ordered PC memory, when I should have ordered laptop memory -totally my fault! - and upon completing the returns details (which is all free post by the way!) I received an email from a wonderful person named Zoe, who happens to be Head of Operations, within 30 minutes giving me a return reference and asking what I wanted to exchange it for (the return request was for replacement not refund).
I replied with my brain fart issue and stated the laptop memory needed.
I received a very fast reply stating the laptop memory will not be in stock until the following Monday.
I then - being the awkward customer I am - asked if it could be posted to a different address as I was on a bit of a time crunch. Zoe replied saying it wouldn't be a problem. I then asked how I could pay the (very small amount) difference..... and she replied saying that they wouldn't charge any more than I had already paid!
If anyone out there doesn't agree about the absolute first class customer focus and service after hearing all my issues and stupidity that Zoe dealt with....
I have no words!
Thank you Zoe and Mr Memory, I am very glad I purchase hardware from you and will continue to do so!
