Industrial SSDsIndustrial strength solid state drives built for the most demanding applications
Virtium’s SSDs are made for extreme conditions in industrial embedded applications. Most SSDs are available with industrial temp (-40ºC to 85ºC) ratings. They include vtGuard® and can be accessed by Virtium’s vtView® software. vtSecure® options include Self-Encrypting Drives (SEDs). Virtium’s SSDs carry three- or five-year warranties. StorFly® SSDs come in three classes: CE (MLC), XE (pSLC) and PE (SLC). TuffDrive® solutions are ideal for heavy-duty networking and embedded applications that require a modest amount of storage for non-SATA designs.

Q1: Is there a utility/tool or operation guide for SMART command?
Q2: What is Virtium’s over-provisioning percentage?
Q3: What is the spare capacity of an overprovisioned drive (resulting in reduced user capacity) used for?
Q4: Can a SATA 6Gb drive be configured for 3Gb access only (i.e. can automatic selection of either 6Gb/3Gb be disabled)?
Q5: How does StorFly SATA negotiate the SATA link speed?
Q6: Do StorFly drives support TRIM?
Q7: How do StorFly drives maintain steady performance over the life of the drive? Does Virtium precondition its drives?
Q8: Does Virtium fully test each drive before shipping it out?
Q9: When do Virtium drives become read only?
Q10: Do Virtium drives stop working when the SMART attribute life remaining is zero?
Q11: Could you clarify the difference between SMART attribute 0xA1 and 0xF9?
SMART attribute 0xF9 (249) = Percentage of remaining spare blocks
If the initial spare block count is 100, then both values will be identical – 50 spare blocks remaining equals 50%.
If the initial spare block count is 110, then the values will be different – 50 spare blocks remaining equals 45%.
Additionally, users can benefit from Virtium’s vtView software, which provides a time-based estimate of the remaining spare blocks versus a percentage.
Q12: What is the NAND endurance of MLC, iMLC, and SLC and how do I read it?
XE class (iMLC, offers 7X endurance compared to CE with 5-year warranty)
Example: 240 GB, 4207 TBW / 9.6 DWPD (5 years)
PE class (SLC, offers 30X endurance compared to CE with 5-year warranty)Example: 256 GB, 23,880 TBW / 51 DWPD (5 years)
*Endurance baseline = one entire drive-write-per-day for the entire warranty period. Results are higher/lower based on various read/write workloads.
Q13: What is the difference between M.2 keys: B, M, and B+M?
Q14: What is Virtium’s secure erase and how does it work?
Q15: What is AHCI?
Q16: Why does Virtium use tantalum capacitors in our designs?
Q17: What type of conformal coat does Virtium use?
Q18: What is MIL-STD-810? Which Virtium products are compliant?
Q19: What is garbage collection?
Q20: What is write amplification (WA) or write amplification factor (WAF)?
Q21: What happens when the SSD's spares run out during a large file transfer?
Q22: Will vtView work with first generation VSFA series SSD?
Q23: How to tell if a drive is in SATA II 3Gbps?
Q1: How does self-encryption differ from other common SSD (e.g. software) encryption solutions?
Q2: What is unique about Virtium’s SED solution?
Q3: What are some key features and corresponding benefits of the SED product?
Feature 1: integrated AES encryption engine with self-encrypting capabilities Benefit: no burden on host system and no extra host encryption elements required.
Feature 2: supports rapid sanitization via “crypto-erase” as well as standard secure eraseBenefit: sanitizes SED in milliseconds, at very low power and is unaffected by power loss to SED; secure erase wipes all NAND blocks including spare area.
Feature 3: supports all SATA formats, not just 2.5” and M.2 like most competitorsBenefit: first industrial SSD supporting full range of embedded form-factors providing system designers with options previously unavailable.
Feature 4: supports all StorFly drives including SLC (PE), iMLC (XE) and MLC (CE)Benefit: wide range of endurance and performance options to meet most any application and price target.
Feature 5: supports industrial operating temperatures (-40Cº to 85Cº)Benefit: extends new levels of security to designs in extreme operating conditions.
Q4: Which Virtium products does SED support?
Q5: Is the encryption automatic or does it require a user command?
Q6: Can the encryption be disabled?
Q7: How is the key on the drive protected?
Q8: What happens to data in flight?
Q9: How is the access to the drive secured to allow only the Authorized user to access it? Is there a boot-up password that is entered via a BIOS dialog?
Q10: What happens to data if the DEK is stored in drive space that goes bad? Is the data lost or is there any way to recover?
Q11: How is data recovery from a crashed SED handled?
Q12: Is drive sanitization now a thing of the past?
Q13: What happens if the sanitization / secure erase is interrupted from a loss of power, does it need to be manually restarted?
Q14: What is the time difference between sanitizing an encrypted vs non-encrypted drive?
Q15. Are there any countries where encryption based products cannot be shipped?
Q16: What security standards are supported with SED?
